[clang-format] Add option to specify explicit config file
Needs ReviewPublic

This diff extends the -style=file option to allow a config file to be specified explicitly. This is useful (for instance) when adding IDE commands to reformat code to a personal style.


clang-format -style=file:<configfilepath> ...

I think not finding the config file should be an error.

Return a "Config file <name> not found" error if the file: style's file isn't found.

Please add a test for the new -style syntax.

@alexfh do you mean to the clang-format-test.el file (which I don't know how to run) or to the FormatTests? If the latter would the right place be TEST(FormatStyle, GetStyleOfFile)?

Add FormatTest for style=file:<path>

The patch has "Context not available" issue (i.e. I couldn't expand to see code around the changes). Could you re-upload the diff?


Could you also update the comment in include/clang/Format/Format.h?


I think the logic of parsing config files should be similar in the "--style=file" case. Could you pull it into a function to avoid duplication?
