Question about exclusion (!) syntax #59

Closed sffc closed 6 years ago

sffc commented 6 years ago

I was trying to find where it is implemented in the code, but unless I'm missing something obvious I can't find it:

https://github.com/tomusdrw/grunt-sync/blob/master/tasks/sync.js

A few questions about it:

  1. Where did the idea for using ! originate (rather than some other syntax for doing exclusion patterns)?
  2. Where is it implemented in grunt-sync?
  3. Are you aware of any other projects using this syntax?

The reason I'm asking is because I'm working on an inclusion/exclusion engine for ICU, and I was intrigued by the idea of using ! for exclusion patterns and want to understand more of the history, particularly the degree to which this syntax is a convention.

Hi @sffc, the pattern is blindly forwarded to https://github.com/isaacs/node-glob#glob-primer The syntax is actually what they do support, so better direct the question to glob maintainers.

Got it, it's just from Glob directly. Thanks for the pointer!
