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.
