I need to rebase all outgoing changesets, and for that I need to mark them as drafts. Is there a shortcut command to do this?
Nevermind. It is:
hg phase -d -f "outgoing()"

At the moment I am looking at transitioning from subversion to Mercurial at work, and as such the Mercurial repository is not yet published.
I have used the authormap argument to transform our usernames to the Mercurial format, which went fine.
Unfortunately two people have been commiting under the same name. The repository is not very large, so I would like to change the authors to match the right people. For that reason I would like to ask:
Is there any way to change the author for a specific changeset, or a list of changesets?
You can use the bundled extension Mercurial Queues (MQ) to change commit authors. Note that MQ will only work as long as history is linear. If there are branches you need to first rebase them off to a temporary side branch, and then after editing rebase them back.
First qimport the changes up till the first changeset you want to modify:
hg qinit
hg qimport -g -r <first-revnr>:tip
Then use qpop or qgoto to navigate to the respective changesets:
hg qgoto <revnr>.diff
And then use qrefresh to change the user info on the currently active changeset:
hg qrefresh -u "Some User <user#example.com>"
You can verify with hg log whether the user was correctly updated. After this, repeat for all other changesets.
When you are done, qpush all patches and use qfinish to finalize the repository.
hg qpush -a
hg qfinish -a
You could as well use the evolve extension. After setting up the extension
hg amend -U && hg prev
for a stack of commits and then hg evolve --all at the end.
Evolve introduces a meta-graph that says which commit replaces which commit.
So when we do hg amend -U a bunch of times, we create commits with a different author that replaced the old commits. hg evolve --all the will use the replacement information to figure out where to move commits that were based on our pre-replaced commits.

In Git it is easy, because remote/branch is pointing to a different commit than branch. How to do it with Mercurial?
If you mean seeing what's different between your local repo and the one you're pushing to, try
hg outgoing
Since Mercurial 2.1, there is also a purely local solution: phases. The draft phase is probably what you are looking for. For details, refer to:
https://www.mercurial-scm.org/wiki/Phases
You may find hg phase <rev> and hg log -r "draft()" interesting.
There is an remotebranch extension that will give you a Git-like setup. It tracks the remote heads for the repositories listed in the [paths] and exposes them as tags named <path>/<branch>. This lets you run
$ hg diff -r foo/default
to see what has changed since the default branch in the foo repository. There is also new revset keywords that let you do things like
$ hg log -r "not pushed()"
to get what
$ hg outgoing
would do, but without any network traffic.
What's the command line call to show all revisions in the draft phase?
hg log --style phases
That will display the log + the phase, since Mercurial 2.7 (2013-08-01).
I'd just use hg outgoing as others are suggesting, but hg summary will tell you too. It may require the --remote option to have it check the remote default server.
If you need to select the changesets for further processing, then you can use the outgoing revset predicate. This lets you re-implement hg outgoing as
hg log -r "outgoing()"
but the real benefit is that you can use this in other contexts, such as
hg strip "outgoing()"
I've looked for that in the manual, but I can't generate a patch for the last commit.
I tried
hg qnew patch_name
but it does only file with
# HG changeset patch
# Parent a6a8e225d16ff5970a8926ee8d24272a1c099f9c
I also tried
hg export tip
but it doesn't do anything. I committed the changes exactly.
How to generate a patch file with the last commit in?
The command to do this is export:
$ hg export -o FILE -r REV
It doesn't require redirection and will thus work correctly on any platform/shell.
Your hg export tip is the best way to do it, and the hg diff and hg log based answers are just lesser versions of the same. What exactly do you see/get when you type hg export tip? What does the output of hg log -p -r tip show?
The changeset tip is just means "the changeset that most recently arrived in my repository" which isn't as useful a concept as you might think, since hg pull and hg tag all create changesets too. If you really want the last thing you committed you'll need a more precise revspec.
Like so:
hg diff -r tip > tip.patch
You can use this command:
hg log -r tip -p > tip.patch
this will generate a patch for just that revision.
If you want to convert the latest commit to a patch file, use
hg qimport -r tip
This will replace the topmost regular commit with an applied MQ patch file.
To generate patches using "mq extensions" in mercurial, you can follow the below given steps. This will create a patch using mercurial:
1) Enabling mq extensions: Add the following lines to your hgrc file and save it.
[extensions]
mq =
2) Creating a patch using mq extensions: To create a patch using mq extensions you can do the following.
hg qnew -e -m "comment you want to enter" bug_name.patch
In the above command, -e flag is for editing the patch and -m flag is for adding a message to the patch.
3) Updating the patch: For updating the patch, you can use the following command when a patch is already applied.
hg qrefresh
I am using Mercurial.
I have some uncommitted changes but I am on the wrong branch, how do I update to the right branch and take the changes with me?
For uncommited changes you can use the Shelve extension:
hg shelve --all
hg up correct_branch_name
hg unshelve
I asked on irc
mpm said
hg diff > mychanges; hg up -C somewhere; hg import --no-commit mychanges
which I had considered but is what I was trying to avoid.

i think you can easily do it by "hg update"ing to a changeset that is a
parent of the branch you're trying to switch to, and then "hg update"ing to the
tip of that branch
so I did that.
hg up -r <shared root rev>
hg up branchIwant
I asked about "why" and was told "you are not allowed to update across branches" which didn't make sense to me at first. Then I realized that because I went through the shared root rev, it isn't across branches.
I usually use
hg qnew
hg qpop
hg up -c <target-rev>
hg qpush
hg qfinish qtip
But I also use jrwren’s approach of going through an ancestor quite regularly.
In mercurial is there a way to diff between 2 different tags?
I have tagged my builds and have a couple commits in between builds and want to figure out the differences between the 2 builds.
hg diff -r tag1:tag2
That's all there is to it.
This answer in the Kiln StackExchange seems quite complete (based on hg diff and hg log):
To see all of the changesets that were introduced between, say, the tags v1.0 and v1.1, run:
hg log -r v1.0:v1.1
To see the net sum of differences introduced in those revisions, you'd instead run:
hg diff -r v1.0:v1.1
Mercurial can even format this output in changelog-style, if you want. Simply add the --style changelog parameter:
hg log -r v1.0:v1.1 --style changelog
