@voronkovich why do you need such functionality?

[voronkovich]

@mkusher, when I create an index for a Symfony project, padawan scans the app/cache directory.

[mkusher]

@voronkovich thanks, nice case

[voronkovich]

@mkusher, I think, you could add support for .gitignore files, or another files with the same format.

[mkusher]

@voronkovich I'm thinking about creating project files, e.g. .padawan-project.json or .padawan-project.yml with the structure like:

exclude:
 - "*/cache/*"
 - "*.cache"
plugins:
 - "mkusher/padawan-symfony"

have you any ideas about it?

[voronkovich]

@mkusher, I think the yaml format would be more appropriate than json. Why not to use just a .padawan.yml (without project suffix) name for the project file?

[mkusher]

@voronkovich Yeah, make sense

It would be awesome if this was configurable from a plugin as well. For instance, if I write a Drupal plugin, it would be extremely cool if I could exclude modules that are not enabled from code completion.

[mkusher]

@cweagans I need to think more about plugin api at all, because now it has very basic abilities.
