mq extension - manage a stack of patches

This extension lets you work with a stack of patches in a Mercurial

repository. It manages two stacks of patches - all known patches, and applied

patches (subset of known patches).

Known patches are represented as patch files in the .hg/patches directory.

Applied patches are both patch files and changesets.

Common tasks (use "hg help command" for more details):

  create new patch                          qnew

  import existing patch                     qimport

  print patch series                        qseries

  print applied patches                     qapplied

  add known patch to applied stack          qpush

  remove patch from applied stack           qpop

  refresh contents of top applied patch     qrefresh

By default, mq will automatically use git patches when required to avoid

losing file mode changes, copy records, binary files or empty files creations

or deletions. This behaviour can be configured with:

  [mq]

  git = auto/keep/yes/no

If set to 'keep', mq will obey the [diff] section configuration while

preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq

will override the [diff] section and always generate git or regular patches,

possibly losing data in the second case.

list of commands:

 qapplied     print the patches already applied

 qclone       clone main and patch repository at same time

 qdelete      remove patches from queue

 qdiff        diff of the current patch and subsequent modifications

 qfinish      move applied patches into repository history

 qfold        fold the named patches into the current patch

 qgoto        push or pop patches until named patch is at top of stack

 qguard       set or print guards for a patch

 qheader      print the header of the topmost or specified patch

 qimport      import a patch

 qnew         create a new patch

 qnext        print the name of the next patch

 qpop         pop the current patch off the stack

 qprev        print the name of the previous patch

 qpush        push the next patch onto the stack

 qrefresh     update the current patch

 qrename      rename a patch

 qselect      set or print guarded patches to push

 qseries      print the entire series file

 qtop         print the name of the current patch

 qunapplied   print the patches not yet applied

 strip        strip a changeset and all its descendants from the repository

use "hg -v help mq" to show aliases and global options
