[Feature request] disable parsing if no composer.json at root

[pelallemant]

What I want to do

I have written a package manager, with a folder packages in which the packages are installed.

When I open atom in the package manager folder, ide-php seems to be parsing all the packages in the folder packages, so it takes lot of time and has no use for me since I go in the packages folder with another atom window.

What I would like

I would like:

• either that ide-php doesn't start if no composer.json is at the root of the atom project directory,
• either a way to precise folder to not parse for a specific package

Best regards
