[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Annotate input dump (2/7)
This patch implements input annotations for diagnostics that suggest
fuzzy matches for directives for which no matches were found. Instead
of using the usual `^~~`, which is used by later patches for good
matches, these annotations use `?` so that fuzzy matches are visually
distinct. No tildes are included as these diagnostics (independently
of this patch) currently identify only the start of the match.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- ? marks fuzzy match when no match is found
- colors error, fuzzy match
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^<<<</,$p'
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3'0 X~~~~~~~~ error: no match found
next:3'1 ? possible intended match
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
This patch introduces the concept of multiple "match results" per
directive. In the above example, the first match result for the
CHECK-NEXT directive is the failed match, for which the annotation
shows the search range. The second match result is the fuzzy match.
Later patches will introduce other cases of multiple match results per
directive.
When colors are enabled, `?` is colored magenta. That is, it doesn't
indicate the actual error, which a red `X~~` marker indicates, but its
color suggests it's closely related.

[FileCheck] Implement -dump-input-context
This patch is motivated by discussions at each of:
* <https://reviews.llvm.org/D81422>
* <http://lists.llvm.org/pipermail/llvm-dev/2020-June/142369.html>
When input is dumped as specified by `-dump-input=fail`, this patch
filters the dump to show only input lines that are the starting lines
of error diagnostics plus the number of contextual lines specified
`-dump-input-context` (defaults to 5).
When `-dump-input=always`, there might be not be any errors, so all
input lines are printed, as without this patch.
Here's some sample output with `-dump-input-context=3 -vv`:

matches, these annotations use `?` so that fuzzy matches are visually
distinct. No tildes are included as these diagnostics (independently
of this patch) currently identify only the start of the match.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- ? marks fuzzy match when no match is found
- colors error, fuzzy match
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^<<<</,$p'
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3'0 X~~~~~~~~ error: no match found
next:3'1 ? possible intended match
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
This patch introduces the concept of multiple "match results" per
directive. In the above example, the first match result for the
CHECK-NEXT directive is the failed match, for which the annotation
shows the search range. The second match result is the fuzzy match.
Later patches will introduce other cases of multiple match results per
directive.
When colors are enabled, `?` is colored magenta. That is, it doesn't
indicate the actual error, which a red `X~~` marker indicates, but its
color suggests it's closely related.

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<

2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1

CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1

[FileCheck] Annotate input dump (2/7)
This patch implements input annotations for diagnostics that suggest
fuzzy matches for directives for which no matches were found. Instead
of using the usual `^~~`, which is used by later patches for good
matches, these annotations use `?` so that fuzzy matches are visually
distinct. No tildes are included as these diagnostics (independently
of this patch) currently identify only the start of the match.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- ? marks fuzzy match when no match is found
- colors error, fuzzy match
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^<<<</,$p'
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3'0 X~~~~~~~~ error: no match found
next:3'1 ? possible intended match
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
This patch introduces the concept of multiple "match results" per
directive. In the above example, the first match result for the
CHECK-NEXT directive is the failed match, for which the annotation
shows the search range. The second match result is the fuzzy match.
Later patches will introduce other cases of multiple match results per
directive.
When colors are enabled, `?` is colored magenta. That is, it doesn't
indicate the actual error, which a red `X~~` marker indicates, but its
color suggests it's closely related.

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.

and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for

patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,

For example:

$ FileCheck -dump-input=help

- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~

CHECK-NOT: foobar
CHECK: def
$ cat input3

```
-vv enables these annotations for FileCheck's implicit EOF patterns as

If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Annotate input dump (3/7)
This patch implements input annotations for diagnostics that report
wrong-line matches for the directives CHECK-NEXT, CHECK-SAME, and
CHECK-EMPTY. Instead of the usual `^~~`, which is used by later
patches for good matches, these annotations use `!~~` to mark the bad
match ranges so that this category of errors is visually distinct.
Because such matches are errors, these annotates are red when colors
are enabled.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would

[FileCheck] Annotate input dump (5/7)

- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Fix --dump-input annotation sort per input line
Without this patch, `--dump-input` annotations on a single input line
are sorted by the associated directive's check-file line. That seemed
fine because that's often identical to the order in which FileCheck
looks for matches for those directives.
The first problem is that an `--implicit-check-not` pattern has no
check-file line. The logical equivalent is sorting in command-line
order, but that's not implemented.
The second problem is that, unlike a directive, an
`--implicit-check-not` pattern applies at many points, between many
different pairs of directives. However, sorting in command-line order
gathers all its associated diagnostics together at one point in an
input line's list of annotations.
In general, it seems to be easier to understand FileCheck's logic when
annotations on a single input line are sorted in the order FileCheck
produced the associated diagnostics, so this patch makes that change.
As documented in the patch, the annotation sort order is also
especially relevant to `CHECK-LABEL`, `CHECK-NOT`, and `CHECK-DAG`, so
this patch updates or extends tests to check the sort makes sense for
them. (However, the sort for `CHECK-DAG` annotations should not
actually be altered by this patch.)

[FileCheck] Annotate input dump (3/7)
This patch implements input annotations for diagnostics that report
wrong-line matches for the directives CHECK-NEXT, CHECK-SAME, and
CHECK-EMPTY. Instead of the usual `^~~`, which is used by later
patches for good matches, these annotations use `!~~` to mark the bad
match ranges so that this category of errors is visually distinct.
Because such matches are errors, these annotates are red when colors
are enabled.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file

- !~~ marks bad match, such as:

- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Annotate input dump (7/7)
This patch implements annotations for diagnostics reporting CHECK-NOT
failed matches. These diagnostics are enabled by -vv. As for
diagnostics reporting failed matches for other directives, these
annotations mark the search ranges using `X~~`. The difference here
is that failed matches for CHECK-NOT are successes not errors, so they
are green not red when colors are enabled.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:

- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- CHECK-DAG overlapping match (discarded, reported if -vv)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- CHECK-NOT not found (success, reported if -vv)
- CHECK-DAG not found after discarded matches (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, discarded match, unmatched input

-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

- T:L'N labels the Nth match result for a pattern of type T from line L of

- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- CHECK-DAG overlapping match (discarded, reported if -vv)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- CHECK-NOT not found (success, reported if -vv)
- CHECK-DAG not found after discarded matches (error)
- ? marks fuzzy match when no match is found

[FileCheck] Fix --dump-input annotation sort per input line
Without this patch, `--dump-input` annotations on a single input line
are sorted by the associated directive's check-file line. That seemed
fine because that's often identical to the order in which FileCheck
looks for matches for those directives.
The first problem is that an `--implicit-check-not` pattern has no
check-file line. The logical equivalent is sorting in command-line
order, but that's not implemented.
The second problem is that, unlike a directive, an
`--implicit-check-not` pattern applies at many points, between many
different pairs of directives. However, sorting in command-line order
gathers all its associated diagnostics together at one point in an
input line's list of annotations.
In general, it seems to be easier to understand FileCheck's logic when
annotations on a single input line are sorted in the order FileCheck
produced the associated diagnostics, so this patch makes that change.
As documented in the patch, the annotation sort order is also
especially relevant to `CHECK-LABEL`, `CHECK-NOT`, and `CHECK-DAG`, so
this patch updates or extends tests to check the sort makes sense for
them. (However, the sort for `CHECK-DAG` annotations should not
actually be altered by this patch.)

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Annotate input dump (6/7)
This patch implements input annotations for diagnostics reporting
CHECK-DAG discarded matches. These diagnostics are enabled by -vv.
These annotations mark discarded match ranges using `!~~` because they
are bad matches even though they are not errors.
CHECK-DAG discarded matches create another case where there can be
multiple match results for the same directive.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- CHECK-DAG overlapping match (discarded, reported if -vv)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- CHECK-DAG not found after discarded matches (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, discarded match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -vv -dump-input=always check4 < input4 |& sed -n '/^<<<</,$p'
<<<<<<
1: abcdef
dag:1 ^~~~
dag:2'0 !~~~ discard: overlaps earlier match
2: cdefgh
dag:2'1 ^~~~
check:3 X~ error: no match found
>>>>>>
$ cat check4
CHECK-DAG: abcd
CHECK-DAG: cdef
CHECK: efgh
$ cat input4
abcdef
cdefgh
```
This shows that the line 3 CHECK fails to match even though its
pattern appears in the input because its search range starts after the
line 2 CHECK-DAG's match range. The trouble might be that the line 2
CHECK-DAG's match range is later than expected because its first match
range overlaps with the line 1 CHECK-DAG match range and thus is
discarded.
Because `!~~` for CHECK-DAG does not indicate an error, it is not
colored red. Instead, when colors are enabled, it is colored cyan,
which suggests a match that went cold.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

- T:L'N labels the Nth match result for a pattern of type T from line L of

- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'

check:3 ^~~
>>>>>>
$ cat check3

CHECK-NOT: foobar

$ cat input3

```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

This shows that the line 3 CHECK fails to match even though its
pattern appears in the input because its search range starts after the
line 2 CHECK-DAG's match range. The trouble might be that the line 2
CHECK-DAG's match range is later than expected because its first match

Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Fix --dump-input annotation sort per input line
Without this patch, `--dump-input` annotations on a single input line
are sorted by the associated directive's check-file line. That seemed
fine because that's often identical to the order in which FileCheck
looks for matches for those directives.
The first problem is that an `--implicit-check-not` pattern has no
check-file line. The logical equivalent is sorting in command-line
order, but that's not implemented.
The second problem is that, unlike a directive, an
`--implicit-check-not` pattern applies at many points, between many
different pairs of directives. However, sorting in command-line order
gathers all its associated diagnostics together at one point in an
input line's list of annotations.
In general, it seems to be easier to understand FileCheck's logic when
annotations on a single input line are sorted in the order FileCheck
produced the associated diagnostics, so this patch makes that change.
As documented in the patch, the annotation sort order is also
especially relevant to `CHECK-LABEL`, `CHECK-NOT`, and `CHECK-DAG`, so
this patch updates or extends tests to check the sort makes sense for
them. (However, the sort for `CHECK-DAG` annotations should not
actually be altered by this patch.)

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.

and are printed first. For brevity in the example above, I've

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were
forced to hunt through a dump of long input looking for the error.
If you think they'll get in the way sometimes, keep in mind that
it's pretty easy to grep for the start of the input dump, which is
`<<<`.
* Colored Annotations: The annotated input is colored if colors are
enabled (enabling colors can be forced using -color). For example,
errors are red. However, as in the above example, colors are not
vital to reading the annotations.
I don't know how to test color in the output, so any hints here would
be appreciated.

[FileCheck] Annotate input dump (1/7)
Extend FileCheck to dump its input annotated with FileCheck's
diagnostics: errors, good matches if -v, and additional information if
-vv. The goal is to make it easier to visualize FileCheck's matching
behavior when debugging.
Each patch in this series implements input annotations for a
particular category of FileCheck diagnostics. While the first few
patches alone are somewhat useful, the annotations become much more
useful as later patches implement annotations for -v and -vv
diagnostics, which show the matching behavior leading up to the error.
This first patch implements boilerplate plus input annotations for
error diagnostics reporting that no matches were found for a
directive. These annotations mark the search ranges of the failed
directives. Instead of using the usual `^~~`, which is used by later
patches for good matches, these annotations use `X~~` so that this
category of errors is visually distinct.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- colors error
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^Input file/,$p'
Input file: <stdin>
Check file: check1
-dump-input=help describes the format of the following dump.
Full input was:
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3 X~~~~~~~~ error: no match found
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
Some additional details related to the boilerplate:
* Enabling: The annotated input dump is enabled by `-dump-input`,
which can also be set via the `FILECHECK_OPTS` environment variable.
Accepted values are `help`, `always`, `fail`, or `never`. As shown
above, `help` describes the format of the dump. `always` is helpful
when you want to investigate a successful FileCheck run, perhaps for
an unexpected pass. `-dump-input-on-failure` and
`FILECHECK_DUMP_INPUT_ON_FAILURE` remain as a deprecated alias for
`-dump-input=fail`.
* Diagnostics: The usual diagnostics are not suppressed in this mode
and are printed first. For brevity in the example above, I've
omitted them using a sed command. Sometimes they're perfectly
sufficient, and then they make debugging quicker than if you were

[FileCheck] Annotate input dump (2/7)
This patch implements input annotations for diagnostics that suggest
fuzzy matches for directives for which no matches were found. Instead
of using the usual `^~~`, which is used by later patches for good
matches, these annotations use `?` so that fuzzy matches are visually
distinct. No tildes are included as these diagnostics (independently
of this patch) currently identify only the start of the match.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- X~~ marks search range when no match is found
- ? marks fuzzy match when no match is found
- colors error, fuzzy match
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check1 < input1 |& sed -n '/^<<<</,$p'
<<<<<<
1: ; abc def
2: ; ghI jkl
next:3'0 X~~~~~~~~ error: no match found
next:3'1 ? possible intended match
>>>>>>
$ cat check1
CHECK: abc
CHECK-SAME: def
CHECK-NEXT: ghi
CHECK-SAME: jkl
$ cat input1
; abc def
; ghI jkl
```
This patch introduces the concept of multiple "match results" per
directive. In the above example, the first match result for the
CHECK-NEXT directive is the failed match, for which the annotation
shows the search range. The second match result is the fuzzy match.
Later patches will introduce other cases of multiple match results per
directive.
When colors are enabled, `?` is colored magenta. That is, it doesn't
indicate the actual error, which a red `X~~` marker indicates, but its
color suggests it's closely related.

[FileCheck] Annotate input dump (5/7)
This patch implements input annotations for diagnostics enabled by -v,
which report good matches for directives. These annotations mark
match ranges using `^~~`.
For example:
```
$ FileCheck -dump-input=help
The following description was requested by -dump-input=help to
explain the input annotations printed by -dump-input=always and
-dump-input=fail:
- L: labels line number L of the input file
- T:L labels the only match result for a pattern of type T from line L of
the check file
- T:L'N labels the Nth match result for a pattern of type T from line L of
the check file
- ^~~ marks good match (reported if -v)
- !~~ marks bad match, such as:
- CHECK-NEXT on same line as previous match (error)
- CHECK-NOT found (error)
- X~~ marks search range when no match is found, such as:
- CHECK-NEXT not found (error)
- ? marks fuzzy match when no match is found
- colors success, error, fuzzy match, unmatched input
If you are not seeing color above or in input dumps, try: -color
$ FileCheck -v -dump-input=always check3 < input3 |& sed -n '/^<<<</,$p'
<<<<<<
1: abc foobar def
check:1 ^~~
not:2 !~~~~~ error: no match expected
check:3 ^~~
>>>>>>
$ cat check3
CHECK: abc
CHECK-NOT: foobar
CHECK: def
$ cat input3
abc foobar def
```
-vv enables these annotations for FileCheck's implicit EOF patterns as
well. For an example where EOF patterns become relevant, see patch 7
in this series.
If colors are enabled, `^~~` is green to suggest success.
-v plus color enables highlighting of input text that has no final
match for any expected pattern. The highlight uses a cyan background
to suggest a cold section. This highlighting can make it easier to
spot text that was intended to be matched but that failed to be
matched in a long series of good matches.
CHECK-COUNT-<num> good matches are another case where there can be
multiple match results for the same directive.

[FileCheck] Fix --dump-input annotation sort per input line
Without this patch, `--dump-input` annotations on a single input line
are sorted by the associated directive's check-file line. That seemed
fine because that's often identical to the order in which FileCheck
looks for matches for those directives.
The first problem is that an `--implicit-check-not` pattern has no
check-file line. The logical equivalent is sorting in command-line
order, but that's not implemented.
The second problem is that, unlike a directive, an
`--implicit-check-not` pattern applies at many points, between many
different pairs of directives. However, sorting in command-line order
gathers all its associated diagnostics together at one point in an
input line's list of annotations.
In general, it seems to be easier to understand FileCheck's logic when
annotations on a single input line are sorted in the order FileCheck
produced the associated diagnostics, so this patch makes that change.
As documented in the patch, the annotation sort order is also
especially relevant to `CHECK-LABEL`, `CHECK-NOT`, and `CHECK-DAG`, so
this patch updates or extends tests to check the sort makes sense for
them. (However, the sort for `CHECK-DAG` annotations should not
actually be altered by this patch.)
