Auto merge of #1555 - puremourning:fixit, r=Valloric
[RFC] YCM Client support for FixIt commands This change provides the client-side support in YouCompleteMe for vim providing a new :YcmFixIt command which applies changes to the vim buffer to implement trivial fixes to common coding errors where the completer provides instructions on how to fix a diagnostic. A note is added "(FixIt)" to the diagnostic text echo'd in vim when a FixIt is available. While this may seem out of the scope of ycmd/YouCompleteMe (as a completion engine), I think it is a really useful feature, and provided straight out of libclang. so I'm sending this slightly incomplete PR (along with the associated ycmd change) to see what the appetite is within the user and maintainer community, and to get feedback on the approach. I know that I need to write some tests, and perhaps tidy up some TODOs, but I would really appreciate any feedback on the approach. Also, I should confess that I haven't yet run the existing tests as I'm having trouble getting them to run on my mac. Hoping that travis will help me out :) I know I also need to update the readme. Testing has been performed manually by going through the list of .c, .cpp and .m files in clang's tests/FixIt folder and ensuring that by hitting :YcmFixIt (actually "@:" a lot!) on each diagnostic, the diagnostic went away (assuming a FixIt was available). I also mangled a number of the clang test such that the fix was spread across multiple lines, etc. I also haven't tested this with completers other than clang completer (due to having trouble one with diagnostics getting them to work) , but of course I will prior to this being ready to merge. I also understand that adding the vim modelines might be divisive, but the standard in this project doesn't match my usual setting :) Happy to remove them if people react angrily. Once again thanks for the time and a great (and improving!) product. I have signed the CLA Demo:

### The `FixIt` subcommand
|
||||
|
||||
Where available, attempts to make changes to the buffer to correct the
|
||||
diagnostic closest to the cursor position.
|
||||
|
||||
Completers which provide diagnostics may also provide trivial modifications to
|
||||
the source in order to correct the diagnostic. Examples include syntax errors
|
||||
such as missing trailing semi-colons, spurious characters, or other errors which
|
||||
the semantic engine can deterministically suggest corrections.
|
||||
|
||||
If no fix-it is available for the current line, or there is no diagnostic on the
|
||||
current line, this command has no effect on the current buffer. If any
|
||||
modifications are made, the number of changes made to the buffer is echo'd and
|
||||
the user may use the editor's undo command to revert.
|
||||
|
||||
When a diagnostic is available, and `g:ycm_echo_current_diagnostic` is set to 1,
|
||||
then the text ` (FixIt)` is appended to the echo'd diagnostic when the
|
||||
completer is able to add this indication. The text ` (FixIt available)` is
|
||||
also appended to the diagnostic text in the output of the `:YcmDiags` command
|
||||
for any diagnostics with available fix-its (where the completer can provide this
|
||||
indication).
|
||||
|
||||
NOTE: Causes re-parsing of the current translation unit.
|
||||
|
||||
NOTE: After applying a fix-it, the diagnostics UI is not immediately updated.
|
||||
This is due to a technical restriction in vim, and moving the cursor, or issuing
|
||||
the the `:YcmForceCompileAndDiagnostics` command will refresh the diagnostics.
|
||||
Repeated invocations of the `FixIt` command on a given line, however, _do_ apply
|
||||
all diagnostics as expected without requiring refreshing of the diagnostics UI.
|
||||
This is particularly useful where there are multiple diagnostics on one line, or
|
||||
where after fixing one diagnostic, another fix-it is available.
