Mercurial

From the perspective of a Git user

Initialize a repository and create a default branch:

hg init

Status of a repository:

hg status

Meaning of the symbols displayed:

? file untracked.
A file added for tracking/commit.
M file modified.
! file missing.
R file marked for removal.

To add files to track:

hg add

Without argument, this command adds all files. Unlike Git, it is not necessary to add modified files again before next commit.

Commit changes:

hg commit

hg log

view commit/changeset logs. Use ``--limit NUM`` to limit displayed logs by NUM (number).

hg revert file

to revert a modified file to the one from last commit. Modified file is saved as ``file.orig``.

hg revert --all

to revert all files as in the last commit.

hg diff

to view changes since last commit. ``hg diff file`` to view changes 
for the give file.

hg cat -r 0 file

to view the specific version (0, in this case) of a file. Similarly,

hg diff -r 0:1 file

to view difference between versions (0 and 1, in this case).

hg diff -r default:stable

to view differences between two branches (``default`` and ``stable``).

hg update NUM

to update working directory to revision NUM. ``hg update`` with no options updates to the most recent commit.

hg parent

to see what commit/changeset the working directory is in.

hg tip

to view the most recent commit.

hg push

to push changes to a central repository.

hg pull repo_url

pull changes from remote repository. Note: this does not update working directory. To
do that use ``hg update``. Alternatively, ``hg pull -u`` does the same function.

hg merge

to perform a merge

Tips

Short log ......... An useful alias to display a short log (source <http://hgtip.com/tips/beginner/2009-10-07-shortlog-for-fun-and-profit/>_). ::

log --template '{rev}:{node|short} {desc|firstline}\n'

Add to ~/.hgrc ::

[alias]
slog = log --template '{rev}:{node|short} {desc|firstline}\n'

Then do hg slog.

Revision/commit numbers ....................... It is sufficient to use the short number displayed to refer to a specific revision. For example ::

$ hg log
changeset:   1:15894d57f0f0
tag:         tip
user:        Vimalkumar Velayudhan <v@....com>
date:        Tue Jan 20 12:21:35 2015 +0000
summary:     modified test file

changeset:   0:42219304850b
user:        Vimalkumar Velayudhan <v@....com>
date:        Tue Jan 20 12:16:01 2015 +0000
summary:     added test file

To display the log for changeset 0:42219304850b ::

 hg log -r0

Refer remote repository by names during push

For example, add to ~/.hgrc (change repository URL accordingly) ::

[paths]
bitbucket = ssh://hg@bitbucket.org/vkvn/testing

To push to this repo, ::

hg push bitbucket

Remove untracked files

::

hg st -un0 | xargs -0 rm

Issues/Questions

Modified files are added for the next commit automatically. There should be a way to commit files selectively. For example, I have a file with changes that I dont’t want to commit yet.
