[FileCheck] Suppress old -v/-vv diags if dumping input The old diagnostic form of the trace produced by -v and -vv looks like: ``` check1:1:8: remark: CHECK: expected string found in input CHECK: abc ^ <stdin>:1:3: note: found here ; abc def ^~~ ``` When dumping annotated input is requested (via -dump-input), I find that this old trace is not useful and is sometimes harmful: 1. The old trace is mostly redundant because the same basic information also appears in the input dump's annotations. 2. The old trace buries any error diagnostic between it and the input dump, but I find it useful to see any error diagnostic up front. 3. FILECHECK_OPTS=-dump-input=fail requests annotated input dumps only for failed FileCheck calls. However, I have to also add -v or -vv to get a full set of annotations, and that can produce massive output from all FileCheck calls in all tests. That's a real problem when I run this in the IDE I use, which grinds to a halt as it tries to capture all that output. When -dump-input=fail|always, this patch suppresses the old trace from -v or -vv. Error diagnostics still print as usual. If you want the old trace, perhaps to see variable expansions, you can set -dump-input=none (the default).

; Create the check file, good input, and bad input.

; For both good and bad input, make sure the -v trace has at least one remark

[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.

[CommandLine] Change help output to prefix long options with `--` instead of `-`. NFC . Part 3 of 5 Summary: By default, `parseCommandLineOptions()` will accept either a `-` or `--` prefix for long options -- options with names longer than a single character. While this change does not affect behavior, it will be helpful with a subsequent change that requires long options use the `--` prefix.

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] Suppress old -v/-vv diags if dumping input The old diagnostic form of the trace produced by -v and -vv looks like: ``` check1:1:8: remark: CHECK: expected string found in input CHECK: abc ^ <stdin>:1:3: note: found here ; abc def ^~~ ``` When dumping annotated input is requested (via -dump-input), I find that this old trace is not useful and is sometimes harmful: 1. The old trace is mostly redundant because the same basic information also appears in the input dump's annotations. 2. The old trace buries any error diagnostic between it and the input dump, but I find it useful to see any error diagnostic up front. 3. FILECHECK_OPTS=-dump-input=fail requests annotated input dumps only for failed FileCheck calls. However, I have to also add -v or -vv to get a full set of annotations, and that can produce massive output from all FileCheck calls in all tests. That's a real problem when I run this in the IDE I use, which grinds to a halt as it tries to capture all that output. When -dump-input=fail|always, this patch suppresses the old trace from -v or -vv. Error diagnostics still print as usual. If you want the old trace, perhaps to see variable expansions, you can set -dump-input=none (the default).

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).

[FileCheck] Suppress old -v/-vv diags if dumping input The old diagnostic form of the trace produced by -v and -vv looks like: ``` check1:1:8: remark: CHECK: expected string found in input CHECK: abc ^ <stdin>:1:3: note: found here ; abc def ^~~ ``` When dumping annotated input is requested (via -dump-input), I find that this old trace is not useful and is sometimes harmful: 1. The old trace is mostly redundant because the same basic information also appears in the input dump's annotations. 2. The old trace buries any error diagnostic between it and the input dump, but I find it useful to see any error diagnostic up front. 3. FILECHECK_OPTS=-dump-input=fail requests annotated input dumps only for failed FileCheck calls. However, I have to also add -v or -vv to get a full set of annotations, and that can produce massive output from all FileCheck calls in all tests. That's a real problem when I run this in the IDE I use, which grinds to a halt as it tries to capture all that output. When -dump-input=fail|always, this patch suppresses the old trace from -v or -vv. Error diagnostics still print as usual.

[FileCheck] Suppress old -v/-vv diags if dumping input The old diagnostic form of the trace produced by -v and -vv looks like: ``` check1:1:8: remark: CHECK: expected string found in input CHECK: abc ^ <stdin>:1:3: note: found here ; abc def ^~~ ``` When dumping annotated input is requested (via -dump-input), I find that this old trace is not useful and is sometimes harmful: 1. The old trace is mostly redundant because the same basic information also appears in the input dump's annotations. 2. The old trace buries any error diagnostic between it and the input dump, but I find it useful to see any error diagnostic up front. 3. FILECHECK_OPTS=-dump-input=fail requests annotated input dumps only for failed FileCheck calls. However, I have to also add -v or -vv to get a full set of annotations, and that can produce massive output from all FileCheck calls in all tests. That's a real problem when I run this in the IDE I use, which grinds to a halt as it tries to capture all that output. When -dump-input=fail|always, this patch suppresses the old trace from -v or -vv. Error diagnostics still print as usual. If you want the old trace, perhaps to see variable expansions, you can set -dump-input=none (the default).

[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.
