Download and install the Sage-combinat patches

We assume that:

• - Sage is already installed (say in /opt/sage) - The user has write access on the Sage installation tree

  - The user has access to: [http://sage.math.washington.edu:2144/]

Edit your Mercurial configuration file (~/.hgrc in your home directory), and insert the following (if not yet there):

[ui]
username = YourFirstName YourLastName <YourEmail>

[extensions]
hgext.mq =
extdiff =
alias =

[alias]
qstatus = status --rev -2:.

[hooks]
pre-qrefresh = (echo "Are you sure you want to refresh the following changes:"; sage -hg status; echo -n "into the patch: "; hg qtop; read -p "(y/n)" answer; test "$answer" = "y"  )

[extdiff] 
cmd.interdiff = hg-interdiff

Download the attachment:sage-combinat script, and run it from anywhere to download and install the Sage-combinat patches:

python sage-combinat install

In case Sage or python is not in the user's path, you may have to specify where they are, as in:

/opt/sage/sage-python sage-combinat install --sage=/opt/sage/sage

Note: starting from sage 3.1.3, the sage-combinat script is readily included in the sage distribution, and you can run it with:

sage -combinat install

Some help is available with:

/opt/sage/sage-python sage-combinat --help
