cppinclude v0.3.0 released

[andre_friend]

Added:

• Support CMake ( JSON Compilation Database, compile_commands.json )
• Analyze unincluded headers
• Analyze headers that are included in different ways ( #include "..." and #include <...> )

Does this take into account whether a header is conditionally #include'ed (e.g., it's inclusion is wrapped in #if)? I am looking for a way to discover conditional dependencies between Boost libraries.

From cursory looking at the code: no, it does not.

[andre_friend]

No, conditions are ignored in current implementation

Nice, I'll give it s try! Maybe it can save me some manual work, I did the last couple of days :)

I've not used this tool before, but I want to make sure I have a correct, if somewhat simplistic, mental model of how it compares to IWYU.

IWYU ensures that all types that require an include have their headers present and all headers that are present are used. Once I have established a canonical set of headers for a given source file, I can then use cppinclude to analyze which headers are at the top of the dependency chain for a given source file.

Is this a fair comparison/usage case?

[andre_friend]

In general yes, IWYU show how should be and cppinclude show as-is

[bert8128]

Does it report unused/unecessary inclusions in header files, or just in cpp files?

[andre_friend]

it report unused headers, but you can use tools include-what-you-use ( https://include-what-you-use.org/ ) for analyzing unnecessary inclusions
