[cfe-dev] Ignore the content from the included files with RecursiveASTVisitor

[Etienne]

Hello,
I am working on a project where I am using the RecursiveASTVisitor to get
metrics from files.
I would like to exclude the parts of the AST that are from included files,
so the metrics I get concern only the file I want to analyze.
I tried to check the location of the Statements, Declarations etc and
exclude them if their location is not the file I am analyzing.
However this solution doesn't really work.
As an example if I call a function from cstdarg:


As the dump shows, the location of the CallExpr is in stdarg.h so my method
excludes it, even if I would like to keep it since it appears in my source
file


Would you have a suggestion to avoid this problem or an other method that
could work?
Thank you
Etienne
