Some combination of qnew, qrefresh, qpop, and qpush.
Try this:
$ # first set up a repo and enable MQ
$ hg init anatoly
$ cd anatoly
$ cat >.hg/hgrc <<EOF
[extensions]
mq =
EOF
$ # some base data
$ echo apples >fruit
$ echo cheddar >cheese
$ hg add .
adding cheese
adding fruit
$ hg commit -m 'initial commit'
$ # some work in progress
$ echo bananas >fruit
$ hg status
M fruit
$ cat fruit
bananas
$ # stash!
$ hg qnew stash
$ hg qpop -a
popping stash
patch queue now empty
$ hg status
$ cat fruit
apples
$ # some unrelated changes
$ echo brie >cheese
$ hg commit -m 'second commit'
$ # unstash!
$ hg qpush stash
applying stash
now at: stash
$ hg status
$ cat fruit
bananas
Having done that, you have a patch called stash, so you can't do qnew
again. You could either pick a new name, or do a qrefresh instead of a
qnew (i think).
Roughly, in this situation:
qnew = "create a new patch, and add all my current uncommitted changes
to that patch"
qrefresh = "add all my current uncommitted changes to an existing patch"
qpop = "remove a patch from the working directory"
qpush = "add a patch to the working directory"
Because MQ allows multiple patches, it treats patches as named
objects, which makes it a bit more verbose than Git's stash for this
use case. Note that there other extensions which provide a simpler
stash behaviour which are more concise.
