• Subversion Tips — Git Tips — CVS Tips
• hg lists basic commands, hg help lists all commands and hg help <command> shows the help for <command>
• Infos are scattered over wiki/UnderstandingMercurial, the wiki/Tutorial, the Workflow Guide and the Hgbook
• Analysis of Git and Mercurial by Google
• Best place to start is Hg Init, a Mercurial tutorial

(As an alternative if the package of the distro is outdated)

1. Remove the original package from the system (removepkg mercurial…)
2. Download and unpack the newest source tarball
3. Cd into unpacked dir and type make to get help
4. Type make install
5. Create the file /etc/profile.d/mercurial.sh with this content:

   export PYTHONPATH="$PYTHONPATH:/usr/local/lib/python2.5/site-package"

Step 4 installs the following content to usr/local/:

lib/python2.5/site-packages/*
bin/hg
share/man/man1/hg.1
share/man/man5/hgrc.5
share/man/man5/hgignore.5

Configuration of mercurial is done in $HOME/.hgrc. See http://www.selenic.com/mercurial/hgrc.5.html

; ~/.hgrc
 
[extensions] 
hgext.graphlog =
hgext.extdiff = 
 
[extdiff] 
cmd.kdiff = kompare
 
[paths]
someShortcut = ssh://someUrl/somePath/someProject

Add this to the file $HOME/.hgrc:

[extensions]
hgext.graphlog =

Usage: hg glog [OPTIONS] - More

Download and install colordiff from www.slackbuilds.org. Then add the following to $HOME/.hgrc:

[extensions]
hgext.extdiff =
 
[extdiff]
cmd.cdiff = colordiff
opts.cdiff = -uprN

Usage: hg cdiff [...] [| less -R]

Add the following to $HOME/.hgrc:

[extensions]
hgext.extdiff =
 
[extdiff]
cmd.kdiff = kompare

Edit ~/.hgrc (More):

[ui]
username = New Username <new@address>

Bookmarks for often accessed remote repositories can be set in .hgrc. Example:

alias 

http://www.selenic.com/mercurial/hg.1.html#urls

Just edit .hg/hgrc in your local repo. More

Cd into the root directory of your project and type hg init. This merely creates the subdir .hg which is the repository. The current dir becomes the working dir of the project.

Add all files to the project by hg add and hg commit

Source

This is a no-brainer See ConvertExtension. Note that the conversion worked witout the cvsps tool mentioned there (On Slack 12.2 with Mercurial 1.4.1)

hg convert <pathToCheckedOutCvsModule>

See hg clone

(Note that there exists also a possibility for internal branches and merges.)

Pulling from another repository usually creates a 2nd head (= 2nd branch) in your repo.

This section describes how to create e.g. client-specific variants of the same main project eg. for special needs of customers.

See also Handling Variants for the solution in SVN.

Verify

Exclude client-specific code from the repo:

• Keep variable code in a separate subdir of the repo.
• Exclude this subdir in .hgignore.
• Optionally create a sub-repo in the subdir to track local changes of the variant.

Sub-repo can always pull from the sub-repo of the trunk. Everything in the main repo can pushed and pulled in every direction.

All variants are part of the whole project:

• Keep variants in separate subdirs of the repo. One subdir per variant.
• Make a symlink to the currently used variant and refer to the variant only via the symlink from the other code
• Exclude the symlink in .hgignore.

Advantages: Every variant is accessible in every repo. Everything can pushed and pulled in every direction.
Disadvantage: Symlink must be created or a fallback mechanism to a default-variant must be implemented.

• Clone the „trunk“-repo for each variant
• Change whatever you want in the variant repo
• Edit generic code only in the trunk
• Pull changes of the trunk into the variants, but never the other way around!

Suitable for projects which are not under your control, i.e. where you just use the code and don't contribute back.

hg revert <file1> [<file2>]

Restores the files in the working directory to the state when they had been last commited. Much more options are posssible, see hg help revert Hgbook Wiki

Do hg rollback (and afterwards hg revert)

Use clone -r <revnumber> <old> <new> to create a repo which contains only the changesets until <revnumber>. Than throw away the original repo and use the cloned repo.
