[emacs][clang-format] Suppress reference to free variable errors (#126254)
vc-git-program is referenced but not defined -- vc-git provides the
definition.

[emacs][clang-format] Add elisp API for clang-format on git diffs (#112792)
New proposed function `clang-format-vc-diff`.

It is the same as calling `clang-format-region` on all diffs between
the content of a buffer-file and the content of the file at git
revision HEAD. This is essentially the same thing as:
    `git-clang-format -f {filename}`
If the current buffer is saved.

The motivation is many project (LLVM included) both have code that is
non-compliant with there clang-format style and disallow unrelated
format diffs in PRs. This means users can't just run
`clang-format-buffer` on the buffer they are working on, and need to
manually go through all the regions by hand to get them
formatted. This is both an error prone and annoying workflow.

Add "clang-format-on-save-mode" minor mode to clang-format.el (#104533)
Add an minor mode which can be optionally used to run clang-format on
save.

Formatting before saving works well and is convenient to avoid having to
remember to manually run clang format.

I've written this as it's own package but it's probably better if the
functionality is supported by clang-format.el.

2f906683ed clang-format.el: Make clang-format work in indirect buffers.
In an indirect buffer, buffer-file-name is nil, so check the base buffer
instead.  This works fine in direct buffers where buffer-base-buffer returns
nil.

f349cc37cc clang-format: Add a fallback style to Emacs mode
Summary:
This allows one to enable `clang-format-buffer` on file save and avoid
reformatting files that are outside of any project with .clang-format style.

c256a4ed17 Fix assume-filename handling in clang-format.el
Summary:
When 'buffer-file-name' is nil 'call-process-region' returned a segmentation fault error.

This was a problem when using clang-format-buffer on an orgmode source code editing buffer.

I fixed this problem by excluding the '-assume-filename' argument when 'buffer-file-name' is nil.

To make it a bit more flexible I also added an optional argument, 'assume-file-name', to specify an assume-filename that overrides 'buffer-file-name'.

ce2f6b413f Use UTF-8 for all communication with clang-format
Summary: Instead of picking the buffer file coding system, always use utf-8-unix for communicating with clang-format.  This is fine because clang-format never actually reads the file to be formatted, only standard input.  This is a bit simpler (process coding system is now a constant) and potentially faster, as utf-8-unix is Emacs's internal coding system.  Also add an end-to-end test that actually invokes clang-format.

8a70450590 Minor cleanups in clang-format.el.
- Enable lexical binding
- Formatting
- Enable file name completion for the clang-format-executable variable
- Add a missing docstring
- When available, use bufferpos-to-filepos and filepos-to-bufferpos. These functions given more precise mapping than byte-to-position and position-bytes.
- Rename arguments of clang-format-region to match the docstring
- Instead of binding local variables to nil and then assigning them, bind them directly to their values
- Make use of the fact that insert-file-contents returns the number of characters it inserted
- Use cl-destructuring-bind to make the code a bit shorter
- Use standard iteration (dolist) instead of mapc with a lambda, which is more common and shorter
- Remove a message that was most likely only present for debugging purposes

a704600295 Revert "Make emacs show when clang-format encountered a syntax error."
This reverts commit 236854, which caused clang-format to always print
'{ "IncompleteFormat": false }' at the top of an incompletely formatted file.
This output causes problems e.g. in Polly's automatic formatting checks. Daniel
tried to fix this in 236867, but this fix had to be reverted due to buildbot
failures. I revert this change as well for now as it is Friday night and
unlikely to be fixed immediately.

7a95ce4399 Make clang-format work in emacs buffers with unicode characters.
Emacs functions by default use character positions; convert characters
to offsets when handing parameters to clang-format and convert byte
offsets we get from clang-format back to character positions.
Reworked the code a bit so the 0-based to 1-based offset calculations
are done in the same place where we do the multi-byte to offset mapping.

e488f5dd1e clang-format: Add -assume-filename option for editor integrations.
With -style=file, clang-format now starts to search for a .clang-format
file starting at the file given with -assume-filename if it reads from
stdin. Otherwise, it would start searching from the current directory,
which is not helpful for editor integrations.

Also changed vim, emacs and sublime integrations to actually make use of
this flag.

This fixes llvm.org/PR17072.

bc36e6e099 Switch the default mode for clang-format to '-file'. Make 'LLVM' the
fallback syntax used when we fail to find a '.clang-format' file. Adjust
variable names appropriately.

Update the editor integration pieces that specify a '-style' option to
specify it as '-style=file'. I left the functionality in place because
even if the preferred method is to use '.clang-format' files, this way
if someone needs to clobber the style in their editor we show how to do
so in these examples.

Also check in a '.clang-format' file for Clang to ensure that separate
checkouts and builds of Clang from LLVM can still get the nice
formatting. =] This unfortunately required nuking the test for the
absence of a '.clang-format' file as now the directory happening to be
under your clang source tree will cause there to always be a file. ;]
