Ignoring the fixed cost of loading the Python interpreter, we're 5.6
times faster. With the Python load time, we're still 3.5 times faster.

Setting up Mercurial: Note: some distributions fails to include bits of distutils by default, you'll need python-dev to install. You'll also need a C compiler and a 3-way merge tool like merge, tkdiff, or kdiff3. First, unpack the source: $ tar xvzf mercurial-<ver>.tar.gz $ cd mercurial-<ver> To install system-wide: $ python setup.py install # change python to python2.3 if 2.2 is default To install in your home directory (~/bin and ~/lib, actually), run: $ python2.3 setup.py install --home=~ $ export PYTHONPATH=${HOME}/lib/python # add this to your .bashrc $ export PATH=${HOME}/bin:$PATH # And finally: $ 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 Exporting a patch: (make changes) $ hg commit $ hg tip 28237:747a537bd090880c29eae861df4d81b245aa0190 $ hg export 28237 > foo.patch # export changeset 28237 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 Symbolic repository names: Mercurial uses an optional file called ~/.hgpaths to track repo locations symbolically. Simply add a line with the name, a space, and a URL: foo$ echo "main http://selenic.com/hg/" >> ~/.hgpaths foo$ hg merge main foo$ hg co
