Oh, sorry, I miss two separate commits here. This patch should not be ready for review. I need to rebase it after commit D20581.

Fix a nit.

This doesn't seem to be the right name. It does more than minimizing headers.

include-fixer/tool/ClangIncludeFixer.cpp
120

These comments seem redundant since it is already clear what those parameters are from variables' names.

128

This should only be for vim-mode or STDINMode I think. For normal mode, we should apply replacements on the rewriter.

206

Same here.

include-fixer/tool/clang-include-fixer.py
30

I think we can simply have one mode where a header is inserted if there is only one result, and a dialog is shown only if there are multiple headers for user to choose from.

30

Also remove semicolons here and below...

94

I think we should also update the buffer with the diff method below. It doesn't make sense to clear the buffer if we are just inserting one line.

Update and address comments.

Can you add some lit tests for the various command line modes clang-include-fixer has now. We can't reasonably test the vim integration but we can tests the bits it's composed of.

maybe 'about the symbol being queried'?

73

'Header' looks like it should be a StringRef too.

include-fixer/IncludeFixerContext.h

I think some doxygen comments would be in order for this struct and its members.

I think function name should start with lower case in llvm.

Function name should start with lower case.

include-fixer/tool/ClangIncludeFixer.cpp
219

I'd put this before creating replacements and right after you get the context since those replacements are not used here. And the "Added #include..." message above doesn't make sense in this mode.

include-fixer/tool/clang-include-fixer.py
48

Maybe handle cases where to_eval is not a valid index?

88

If there is only one candidate, it doesn't make sense to ask users to choose it IMO. We can simply insert the header in this case.

And I think we should make users pick the correct header if there are multiple candidates by default. What do you think, Ben? @bkramer

I agree, we should ask by default when there is more than one suggested header.

vim can handle this for us.

Remove unneeded headers.

Do we want UINT_MAX? I find the wording in the standard to be too involved for me to easily understand that this is both well-defined and what we want and portable.

include-fixer/IncludeFixer.h
63–73
  1. This only needs one style, so I think we should pass it in instead of FilePath and FallbackStyle
  2. From the docs it seems like FirstIncludeOffset should always be INT_MAX? Can we just leave out that parameter and make the function do the right thing?
  3. Generally, I'd order parameters by "importance", that is, the ones that are core to the functionality go first (C++ kinda implies this by only allowing later parameters being defaultable); so basically, I'd make this:

    .. insertHeader(StringRef Code, StringRef Header, const FormatStyle& Style);

Refactor createReplacementsForHeaders.

I don't see why we'd want Style to be optional.

include-fixer/tool/ClangIncludeFixer.cpp
110

We might still want to use clang::format::getStyle("file", FilePath, FallbackStyle);, which will use format style defined in clang-format config file in the path, if such config file exists. Style option is just a fallback style.

Use format::getStyle to get clang-format style.

Using a default argument in Style can simplify the code in some cases, for example in the Unittest. @klimek might have idea?

I think you can drop the part about 'uninitialization' from this comment.

This doesn't look clang-formatted :p

This is still missing documentation on what the -1U special case means.

Add -1U comment back.

Currently, the header is only inserted at the first line of the file because we don't output the FirstIncludeOffset to py script. A follow-up patch will come soon.
