mydeveloperday 8b7881a084 [clang-format] Add basic support for formatting JSON
I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support  in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.

I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to  [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.

This has come up from time to time:

{D10543}
https://stackoverflow.com/questions/35856565/clang-format-a-json-file
https://bugs.llvm.org/show_bug.cgi?id=18699

I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).

This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level

This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.

Vitali Lovich 64cf5eba06 [clang-format] Add new LambdaBodyIndentation option
Currently the lambda body indents relative to where the lambda signature is located. This instead lets the user
choose to align the lambda body relative to the parent scope that contains the lambda declaration. Thus:

someFunction([] {
  lambdaBody();
});

will always have the same indentation of the body even when the lambda signature goes on a new line:

someFunction(
    [] {
  lambdaBody();
});

whereas before lambdaBody would be indented 6 spaces.

Currently, it uses `Standard: C++03` setting for clang-format, but this breaks e.g. u8"string" literals.
Also, angle brackets are the only place where C++03-specific formatting needs to be applied.

Max Sagebaum dda978eef8 [clang-format] Option for empty lines after an access modifier.
The current logic for access modifiers in classes ignores the option 'MaxEmptyLinesToKeep=1'. It is therefore impossible to have a coding style that requests one empty line after an access modifier. The patch allows the user to configure how many empty lines clang-format should add after an access modifier. This will remove lines if there are to many and will add them if there are missing.

This updates the canonical text proto raw string delimiter to `pb` for Google style, moving codebases towards a simpler and more consistent style.

Also updates a behavior where the canonical delimiter was not applied for raw strings with empty delimiters detected via well-known enclosing functions that expect a text proto, effectively making the canonical delimiter more viral. This feature is not widely used so this should be safe and more in line with promoting the canonicity of the canonical delimiter.

The new option, `IndentAccessModifiers`, if enabled, forces the content inside classes, structs and unions (“records”) to be indented twice while removing a level for access modifiers. The value of `AccessModifierOffset` is disregarded in this case, aiming towards an ease of use.

// clang-format off
        #pragma HLS UNROLL
        // clang-format on
        for (int j = 0; j < 5; j++) {
// clang-format off
            #pragma HLS UNROLL
            // clang-format on

```

can become

```
    for (int i = 0; i < 5; i++) {
        #pragma HLS UNROLL
        for (int j = 0; j < 5; j++) {

Ben Hamilton e7b4feea8e [Format/ObjC] Add NS_SWIFT_NAME() and CF_SWIFT_NAME() to WhitespaceSensitiveMacros
The argument passed to the preprocessor macros `NS_SWIFT_NAME(x)` and
`CF_SWIFT_NAME(x)` is stringified before passing to
`__attribute__((swift_name("x")))`.

ClangFormat didn't know about this stringification, so its custom parser
tried to parse the argument(s) passed to the macro as if they were
normal function arguments.

That means ClangFormat currently incorrectly inserts whitespace
between `NS_SWIFT_NAME` arguments with colons and dots, so:

```
extern UIWindow *MainWindow(void) NS_SWIFT_NAME(getter:MyHelper.mainWindow());
```

becomes:

```
extern UIWindow *MainWindow(void) NS_SWIFT_NAME(getter : MyHelper.mainWindow());
```

which clang treats as a parser error:

```
error: 'swift_name' attribute has invalid identifier for context name [-Werror,-Wswift-name-attribute]
```

Thankfully, D82620 recently added the ability to treat specific macros
as "whitespace sensitive", meaning their arguments are implicitly
treated as strings (so whitespace is not added anywhere inside).

This diff adds `NS_SWIFT_NAME` and `CF_SWIFT_NAME` to
`WhitespaceSensitiveMacros` so their arguments are implicitly treated
as whitespace-sensitive.

  New tests added. Ran tests with:

Alex Richardson e7bd058c7e [clang-format] Allow configuring list of macros that map to attributes
This adds a `AttributeMacros` configuration option that causes certain

This is motivated by our CHERI C/C++ fork which adds a __capability
qualifier for pointer/reference. Without this change clang-format parses
many type declarations as multiplications/bitwise-and instead.
I initially considered adding "__capability" as a new clang-format keyword,
but having a list of macros that should be treated as attributes is more
flexible since it can be used e.g. for static analyzer annotations or other language
extensions.

Example: std::vector<foo * __capability> -> std::vector<foo *__capability>

Depends on D86775 (to apply cleanly)
