mq extension - patch management and development
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):
prepare repository to work with patches qinit
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
print name of top applied patch qtop
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
list of commands:
qapplied print the patches already applied
qclone clone main and patch repository at same time
qcommit commit changes in the queue repository
qdelete remove patches from queue
qdiff diff of the current patch
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
qinit init a new queue repository
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
qrestore restore the queue state saved by a rev
qsave save current queue state
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 revision and all later revs on the same branch
use "hg -v help mq" to show aliases and global options
