Some neat sage command line options

June 29th, 2008sage

I haven’t looked at sage -h for a while and was surprised to see many useful convenience features that have been added. I will highlight some ones that I’ve been using constantly that makes Sage development more convenient.

sage  -b [branch]   -- switch to and build SAGE branch in devel/sage-branch
sage  -br [branch]  -- switch to, build, and run SAGE branch in devel/sage-branch
sage  -clone [new branch] -- clone and run a new branch of the SAGE library from current branch
sage  -python       -- run the python interpreter
sage  -sh           -- run $SHELL (/opt/local/bin/zsh) with SAGE environment variables set
sage  -t [-optional] [-verbose] [-long] -- test examples in .py, .pyx, .sage or .tex files
                   -optional -- include examples with 'optional' and 'package'
                   -long     -- include lines with the phrase 'long time'
                   -verbose  -- print debuging output during the test

In particular, sage -sh is really useful for setting all the shell variables.
