Setting up Mercurial in your home directory:

Note: Debian fails to include bits of distutils, you'll need python-dev to install. Alternately, shove everything somewhere in your path.

$ tar xvzf mercurial-<ver>.tar.gz $ cd mercurial-<ver> $ python2.3 setup.py install --home ~ $ export PYTHONPATH=${HOME}/lib/python # add this to your .bashrc $ export HGMERGE=tkmerge # customize this $ hg # test installation, show help

If you get complaints about missing modules, you probably haven't set PYTHONPATH correctly.

Setting up a Mercurial project:

$ cd linux/ $ hg init # creates .hg $ hg status # show changes between repo and working dir $ hg diff # generate a unidiff $ hg addremove # add all unknown files and remove all missing files $ hg commit # commit all changes, edit changelog entry $ hg export # export a changeset as a diff

Mercurial will look for a file named .hgignore in the root of your repository contains a set of regular expressions to ignore in file paths.

Mercurial commands:

$ hg history # show changesets $ hg log Makefile # show commits per file $ hg checkout # check out the tip revision $ hg checkout <id> # check out a specified changeset

# IDs can be tags, revision numbers, or unique # subsets of changeset hash numbers

$ hg add foo # add a new file for the next commit $ hg remove bar # mark a file as removed $ hg verify # check repo integrity $ hg tags # show current tags $ hg annotate [files] # show changeset numbers for each file line

Branching and merging:

$ cd .. $ mkdir linux-work $ cd linux-work $ hg branch ../linux # create a new branch $ hg checkout # populate the working directory $ <make changes> $ hg commit $ cd ../linux $ hg merge ../linux-work # pull changesets from linux-work

Importing patches:

Fast: $ patch < ../p/foo.patch $ hg addremove $ hg commit

Faster: $ patch < ../p/foo.patch $ hg commit lsdiff -p1 ../p/foo.patch

Fastest: $ cat ../p/patchlist | xargs hg import -p1 -b ../p

Network support:

# pull the self-hosting hg repo foo$ hg init foo$ hg merge http://selenic.com/hg/ foo$ hg checkout # hg co works too

# export your current repo via HTTP with browsable interface foo$ hg serve -n "My repo" -p 80

# merge changes from a remote machine bar$ hg merge http://foo/ bar$ hg co # checkout the result

# Set up a CGI server on your webserver foo$ cp hgweb.cgi ~/public_html/hg-linux/index.cgi foo$ emacs ~/public_html/hg-linux/index.cgi # adjust the defaults

# Give symbolic names to repos foo$ echo "main http://selenic.com/hg/" >> ~/.hgpaths # one pair per line foo$ hg merge main foo$ hg co
