Ehsan Akhgari fae3ac3e9b [clang-tidy] Add -path option to clang-tidy-diff.py
Summary:
This flag allows specifying a custom path for the compilation
database.  Unfortunately we can't use the -p flag like other
clang-tidy tools because it's already taken.

Krasimir Georgiev 1b8bfd4b76 [clangd] Implement format on type
Summary:
This patch adds onTypeFormatting to clangd.

The trigger character is '}' and it works by scanning for the matching '{' and formatting the range in-between.

There are problems with ';' as a trigger character, the cursor position is before the `|`:
```
int main() {
  int i;|
}
```
becomes:
```
int main() {  int i;| }
```
which is not likely what the user intended.

Also formatting at semicolon in a non-properly closed scope puts the following tokens in the same unwrapped line, which doesn't reformat nicely.

Jonas Devlieghere 2789043178 [clang-tidy] Add check 'modernize-return-braced-init-list'
Summary:
Replaces explicit calls to the constructor in a return with a braced
initializer list. This way the return type is not needlessly duplicated in the
return type and the return statement.

```
Foo bar() {
  Baz baz;
  return Foo(baz);
}

// transforms to:

Foo bar() {
  Baz baz;
  return {baz};
}
```

Benjamin Kramer bb1cdb63e5 Add a prototype for clangd
clangd is a language server protocol implementation based on clang. It's
supposed to provide editor integration while not suffering from the
confined ABI of libclang.

This implementation is limited to the bare minimum functionality of
doing (whole-document) formatting and rangeFormatting. The JSON parsing
is based on LLVM's YAMLParser but yet most of the code of clangd is
currently dealing with JSON serialization and deserialization.

This was only tested with VS Code so far, mileage with other LSP clients
may vary.

Manuel Klimek a47515ec4a Improve include fixer's ranking by taking the paths into account.
Instead of just using popularity, we also take into account how similar the
path of the current file is to the path of the header.
Our first approach is to get popularity into a reasonably small scale by taking
log2 (which is roughly intuitive to how humans would bucket popularity), and
multiply that with the number of matching prefix path fragments of the included
header with the current file.
Note that currently we do not take special care for unclean paths containing
"../" or "./".

Summary:
This checks for calls to double-precision math.h with single-precision
arguments.  For example, it suggests replacing ::sin(0.f) with
::sinf(0.f).

Alexander Kornienko ebdfb9cf0c [Clang-tidy] check for malloc, realloc and free calls
Summary:
This checker flags the use of C-style memory management functionality and notes about modern alternatives.
In an earlier revision it tried to autofix some kind of patterns, but that was a bad idea. Since memory management can be so widespread in a program, manual updating is most likely necessary.
Maybe for special cases, there could be later additions to this basic checker.

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

Benjamin Kramer b568d99dd7 [clang-rename] Prune away AST nodes more correctly and effectively when looking for a point
Due to the way the preprocessor works nodes can be half in a macro or a
different file. This means checking the file name of the start location
of a Decl is not a correct way of checking if the entire Decl is in that
file. Remove that flawed assumption and replace it with a more effective
check: If the point we're looking for is *inside* of the begin and end
location of a Decl, look inside.

This should make clang-rename more reliable (for example macro'd namespaces
threw it off before, as seen in the test case) and maybe a little faster
by pruning off more stuff that the RecursiveASTVisitor doesn't have to
drill into.

Eric Fiselier 732a3e0dd1 [clang-tidy] Fix identifier naming for initializer list member initializers.
Summary:
This patch adds handling for member initializers in a constructors initializer list. Previously we only handled base-class and delegating initializers, which are transformed by the `TypeLoc` matcher. For Example:

```
// Style options: All identifiers should start with an upper case letter.
struct base { ...  }; 
struct der :  base {
  int field;  // FIXES: int Field;
  der() : der(42) {} // FIXES: Der() : Der(42) {}
  der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)
  // Note that `field` doesn't get replaced
};
```

Eric Liu ff51f011d1 [change-namespace] handle constructor initializer: Derived : Base::Base() {} and added conflict detections
Summary:
namespace nx { namespace ny { class Base { public: Base(i) {}} } }
namespace na {
namespace nb {
class X : public nx::ny {
public:
  X() : Base::Base(1) {}
};
}
}

When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
 "Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.

The namespace lookup is tricky here, we simply replace "Base::Base()" with "nx::ny::Base()" as a workaround, which compiles but not perfect.
