Closing this bug as process substitution on the command line makes it possible to import a patch generated by any tool without writing it to a temporary file first.

As an alternative, you could also create an empty patch with "quilt new" and then use "git diff | quilt fold" to import the patch contents generated by the external tool (git in this case).

Yes this works for me in Cygwin Bash:

$ quilt import -P git.diff <(git diff)

Completely forget about Process Substitution.

That satisfied my needs.

Unfortunately I can't find any trace of the candidate patches mentioned in bug #46958. I must have deleted them after closing the bug.

With bash, you can use the following to achieve what you want:

# quilt import -P git.diff <(git diff)

It should work with other SCM, and with any shell supporting process substitution. Does it work for you?

Found ugly alternative:

  svn diff | quilt import -f -P new.diff -p0 /dev/stdin

and broken by interesting:

  hg diff | quilt fold

I would like to use quilt with Git and

  • to avoid numerous "quilt add" and
  • to allow to import existing Git changes as patch

I'd like to have syntax:

  git diff | quilt import -P fix.patch -

Currently it failed with:

  Patch - does not exist

I can emulate behavior with:

  git diff >fix.patch
  quilt import fix.patch
  rm fix.patch

though it doesn't look funny in 2017 ((

Similar request is closed without no meaningful reason:


If this request WONTFIX please answer how I can import already applied changes from Git/HG/SVN managed sources avoiding SH/BASH kong-fu (to make "quild add ..." or save patch, un-apply changes, etc).
