Re: [RFC] extending git-ls-files --exclude.

Marco Costalba [off-list ref] writes:

This cumulative effect brakes local scoping of .gitignore files in 
corresponding subdirectory.

As example in a directory A we can have a .gitignore file with

!foo.html
*.html

because we want to special case 'that' foo.html in 'that'
directory.

I guess that !foo.html I wrote was a bad example of special case
not being specific enough.  Saying "!/foo.html" should work
[*1*], so I think "cumulative effect _breaks_" is a bit too strong
a word.

Having said that,...

This can be powerful and flexible but also prone to errors. 

While I also suspect it _might_ be prone to user errors, at
least to some classes of users, Catalin (and Peter as well I
suspect, although I may be mistaken by what he originally meant
by "cumulative") seems to think it is OK.  As a developer of
another Porcelain (qgit), your input is as valuable as others,
so...

BTW, I am CC'ing git list because I saw you forwarded your
entire message to the list as a quoted message form.  Please do
not do that.  I cannot distinguish a message like that with a
message with nothing but quote and no original contents, which I
normally discard without even reading.

*1* I just tried, and it seems to work.

  $ rm -f .gitignore ppc/.gitignore
  $ (echo '!/foo.bar'; echo '*.bar') >.gitignore
  $ for i in foo.bar baz.bar; do date >$i; date >ppc/$i; done
  $ git-ls-files --others --exclude-per-directory=.gitignore | grep '\.bar'
  foo.bar
  $ rm -f .gitignore ppc/.gitignore
