fileExclusionRegExp behavior with multiple files/directories with the same name

[mickeyreiss]

Hi there!

I've noticed a limitation in the fileExclusionRegExp configuration option.

I'm using "Optimizing a Whole Project"-style compilation with a number of modules, and I'm having trouble specifying the set of files I'd like to copy over to the build directory.

Here's a simplified directory listing of my project:

/app/scripts/a.js
/app/scripts/b.js
/app/scripts/c.js
/tools/scripts/d.js

The Problem

During compilation, I would like a, b and c to be copied over but I'd like to ignore d.js as it is not intended for distribution.

• I tried fileExclusionRegExp: /^scripts$/, but that excludes all 4.
• I tried fileExclusionRegExp: /tools\/scripts/, but that excludes none of the 4.
• I've tried a few more similar permutations, but I couldn't figure out a way to include all files in /app/scripts without the files in /tools/scripts.

The Workaround

The only workaround I've been able to find is to rename /tools/scripts to something different. This feels kludgy to me; why shouldn't fileExclusionRegExp support multiple files or directories with the same name?

Potential Solutiosn

Some solutions come to mind, such as executing the provided RegExp on relative project paths (i.e. /app/scripts/a.js instead of scripts and a.js). Another idea would be to reinstate functionality for excluding particular directories.

Thanks!

I can see where a kind of fullPathExclusionRegExp might be useful. Although, r.js cannot do all the kinds of exclusions a developer may want, and relying on post-r.js build processes are still suggested for maximum flexibility.

Putting this in the 2.2.0 bucket for consideration.

What, exactly do you mean by post-r.js build processes? Is that essentially a script that goes through my r.js build directory and deletes unnecessary files?

[jrburke]

Yes, or if you have a script that drives r.js now, adding the removal after the r.js step.

@jrburke I also find that it would be very useful to be able to be able to use more flexible regular expressions. In projects, which have bower_components with hundreds of dependencies, developers have to be extra careful with what they exclude from the build. Being able to use something like that would be extremely beneficial for build time. Thank you.
