ede-directory-project-p

ede-directory-project-p is a compiled Lisp function in `files.el'.

(ede-directory-project-p DIR &optional FORCE)

Return a project description object if DIR is in a project.
Optional argument FORCE means to ignore a hash-hit of 'nomatch.
This depends on an up to date `ede-project-class-files' variable.
Any directory that contains the file .ede-ignore will always
return nil.

Consider using `ede-directory-project-cons' instead if the next
question you want to ask is where the root of found project is.
