I have been making some changes to my working directory, and noticed that I have accidentally been working on the wrong branch. I have not committed anything yet, and I would like my next commit to go against another branch. What is the best way to do this?
The Shelve extension can give you grief, and this can be done entirely with Mercurial commands. Krtek almost had it but he used export instead of diff. Try this:
hg diff --git > ~/saved-work.patch
hg update --clean desiredbranch
hg import --no-commit ~/saved-work.patch
You should be able to just hg up otherbranch. It is important that you do not use the --clean option to hg up, either directly or via an alias as that will discard your uncommitted changes.
Another option is to use one of the extensions that provides hg shelve. The process would then be:
$ hg shelve --all
$ hg up otherbranch
$ hg unshelve
That will create a patch of your changes within the .hg directory, returning your working directory to a clean state, switch to the 'otherbranch', and then apply the saved patch.
I don't know if it is the best solution, but you can follow these steps :
1° hg diff --git > modifications.patch
2° hg update -C the_right_branch
3° hg patch modifications.patch
Maybe it's better to copy modifications.patch somewhere safe, just in case.
edit: update with diff instead of export. Thanks to the commenters.

I am using Mercurial ("HG"), I am trying to Clean the repo from uncommitted Changes using :
hg update --clean -R rpeo_path
It will Clean The repo and move to tip ( it will change the changeset )
How can i Clean the repo from uncommitted changes and stay in the current Changeset ?
Thanks in advance
The simplest is probably to use hg revert --all.
With no revision specified, revert the specified files or directories
to the contents they had in the parent of the working directory. This
restores the contents of files to an unmodified state...
The --all option will
revert all changes when no arguments given
I solved :
current_changeset = hg id -i
hg update --clean -R repo_path -r current_changeset
Please keep me updated if you have another opinion
I issued hg qnew without realizing that it includes any outstanding changes into the patch. I'd like to back that out and pick only specific changes using hg qrecord. How can I undo qnew?
Your answer definitely works — with newer Mercurial's you can use hg strip --keep to avoid doing the import step:
$ hg strip --keep .
$ hg qdelete patch-name
The --keep flag makes strip ignore the working copy while working, that is, it deletes the commit (like hg qpop would do) but it doesn't undo the changes to the files. After stripping you still have the patch in your series (unapplied) and you can then delete it.
I've found an anwer here:
hg qpop
hg import --no-commit .hg/patches/patch-name
hg qdelete patch-name
Please add a better way, if you know.
Update: Based on Aldo's answer, there is another way:
hg qnew test
# We can undo the above qnew as:
hg qrefresh -X '*'
hg qpop -f
hg qdelete test
If you just want to undo the latest qnew retaining all your local changes, one option is:
qcrefresh 123
hg qpop -f
hg qdelete <name of the patch>
Notice that 123 is just a random string: you are telling mercurial to only include the (hopefully nonexistsnt) 123 file in the current patch.
Newer versions of Mercurial When you issue will issue a warning about the fact 123 file does not exist, but this is exactly what we want here.
If you want to retain some of the changes in the current path, you can use the qcrefresh command from the crecord extension, which allows to graphically select the changes to be included in the current patch. You need to download it from Bitbucket, extract the archive and configure it in .hgrc:
[extensions]
crecord = <path/to/crecord/package>
If you do an hg pull and then an hg update (or an hg merge), is there a way to back this out? Ie: revert your repository to the state prior to doing the hg pull?
I believe you can do hg update -r n where you would specify the changeset prior to the pull as n. Though I'm guessing this will still leave the changesets in your repository but this isn't really what we want. ??
hg strip will remove revisions from a repository. Like all powerful commands, its dangerous, so be careful.

If you catch your mistake immediately (or reasonably soon), you can just use hg strip REV to roll back the latest (one or more) changes. ...
Ok, you can't rollback because you've done a commit. What you can do is use 'hg strip' which is part of mq (after 2.8 strip is in it's own extension), or use mq to remove the changes. Either way I suggest you do everything on another clone, just in case.
To do strip, update to a revision that you want to keep, and then
hg strip <REV>
where <REV> is the first revision you want to remove. It will remove that one and all decendents (including your merge commit).
Alternatively you can
hg qnew (if you don't already have a patch queue)
hg qimport <REV>
which will import a single revision into the patch queue. You can then add more, and then use the mq commands to edit, rearrange, delete, or whatever you want to do with those revisions. qdel deletes the current patch.
Edit: Obviously, you'll need to enable the MQ extension for both of these, unless you're using 2.8 or later. In that case strip is in the strip extension, and mq in the mq extension. Both are shipped with the standard installation.
hg --rollback can be used to undo the last transaction so as long as your hg pull is still the most recent transaction then you can use that. This command should be used with care though. See here for some more details.
you can:
hg update -C <version>
see the mercurial FAQ.
If you want to remove all traces of the pull form your history then you need to use an extension as Bert F suggests (the philosophy in mercurial is to never change history)
if you dont mind history containing your mistake you have two slightly different options hg update -C -r which will create a new branch at the version you specify or hg revert -r which will stay on the same branch but create a new uncommited change undoing everything.
I have a large commit of many files on one branch, I need to transfer the modifications of a single file in that changeset to another branch. How can I do this? I am mostly using TortoiseHg but commandline solutions are also fine.
If I go to the changeset in TortoiseHg and select the file I can see the diffs I want to transfer, but not a way to actually apply them.
You can get the patch for just that file using:
hg log -r THEREVISIONWITHLOTSOFCHANGES -p -I path/to/justthatfile > justthatfile.patch
which you can then import on whatever branch you want by doing:
hg update anotherbranch
hg import --no-commit justthatfile.patch
hg commit
The most basic solution is to dump the patch of the file, apply it to the current working revision, and commit it (assuming you're at the root of the repository):
$ hg up <revision-to-apply-the-patch-to>
$ hg diff -c <revision-containing-the-patch> <files-to-include> | patch -p0
$ hg ci -m "Transplanting selected changes from <revision-contain...>"
The drawback of this method is that it isn't very obvious what you've done from a revision history perspective. A good commit message helps here, but the history graph gives no hint about the process of transplanting some changes. In that case merging and reverting may be a better solution:
$ hg up <revision-to-apply-the-patch-to>
$ hg merge -r <revision-containing-the-patch>
$ hg revert --no-backup <files-to-exclude>
$ hg ci -m "Merge in changes of <files-to-include>"
Probably there are more solutions to do this -- these two came to my mind first.
Suppose that I have made some changes in the working directory and accidentally marked several files (that include some of the modified ones) for removal. How do I unmark the files for removal without losing the changes I have made?
Just hg add the files.
I don't know why you're getting some many answers that modify the working directory. If you've accidentally marked some files for removal you can undo it with add.
ry4an#four:~/hgtest$ hg status --all
M another_file
C a_file
ry4an#four:~/hgtest$ hg remove --after --force *
ry4an#four:~/hgtest$ hg status --all
R a_file
R another_file
ry4an#four:~/hgtest$ hg add *
ry4an#four:~/hgtest$ hg status --all
M another_file
C a_file
That said, don't use --force with hg remove or ever really. Also try to get in the habit of using hg forget instead of hg remove --after,
there are two options using hg revert :
hg revert -a
which will go back to the previous revision and put all your changes in new files with .orig appended to the names
hg revert [names of files to unremove] to just revert those files
i'd probably go with the latter
hg revert
I'm pretty sure Mercurial even makes backups of your changes by default.
If the file exists, (likely if you've marked it for removal with hg forget or if you've modified it then hg removed it), do hg add [file] to add it back with any changes made after the last commit and before forgetting the file.
If the file does not exist (likely if the file was unmodified and you've marked the file for removal using hg remove), do hg revert [file] to revert it back to its state in the parent of the working directory.
I had the exact same problem. hg add is the inverse to hg forget (just as the opposite is true). However, attempting to re-add the directory itself did not work. Instead, I had to use hg add on each file:
hg st | egrep "^R" | sed -e "s/R //" | xargs hg add
Hope that helps. Note that in my case, there was nothing I legitimately wanted to remove. If you have files you definitely want to remove, adjust the grep accordingly.
Following your comment to jk, I checked hg forget. It seems to be just a shortcut for hg remove -Af, meaning that this is the real opposite of hg add.
Following that, if you've used hg remove -Af, then you should be able to revert that using hg add (I just tried it and seems to work).
The markers are stored in .hg/dirstate file. All you need to do i to get a one from before issuing hg remove -Af. It may look like this (not tested):
hg clone bad-repo orig-repo
cp orig-repo/.hg/dirstate bad-repo/.hg/dirstate
cd bad-repo
hg status
The last command should show the status from before removing files.
I removed a bunch of unmodified files:
hg remove *
This is what I had to do to get them back:
hg revert --all
Nothing else worked. Not hg add not hg add * nor hg revert *
