./devel/include-what-you-use, Analyze #includes in C and C++ source files

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.21, Package name: include-what-you-use-0.21, Maintainer: pkgsrc-users

"Include what you use" means this: for every symbol (type, function
variable, or macro) that you use in foo.cc, either foo.cc or foo.h
should #include a .h file that exports the declaration of that symbol.
The include-what-you-use tool is a program that can be built with the
clang libraries in order to analyze #includes of source files to find
include-what-you-use violations, and suggest fixes for them.

The main goal of include-what-you-use is to remove superfluous #includes.
It does this both by figuring out what #includes are not actually needed for
this file (for both .cc and .h files), and replacing #includes with
forward-declares when possible.

Log message:
include-what-you-use: updated to 0.21

iwyu 0.21 compatible with llvm+clang 17 is released. Major changes:

[iwyu] Improve analysis of type aliases (typedef and using)
[iwyu] Improve analysis of namespace aliases (namespace xyz = foobar)
[iwyu] Improve support for elaborated forward declarations (typedef struct Foo Bar;)
[iwyu] Improve handling of "autocast" and function return types, \ 
particularly with complex template types.
[iwyu] Add new IWYU pragma: always_keep, which lets a header announce that it \ 
should always be kept wherever included
[iwyu] Automatically use builtin libc++ mappings if libc++ is the active \ 
standard library
[mappings] Improve mappings for libc++ and posix headers
