Tips for Using SAGE

GeoGebra [http://www.geogebra.org/cms/ GeoGebra] is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. Here's how you can embed it in the SAGE notebook.
1. In GeoGebra: Create some geometric construction or plot an algebraic expression. See [http://www.geogebra.org/cms/index.php?option=com_content&task=blogcategory&id=69&Itemid=56 this page] for more details.
2. In GeoGebra: File> Export> Dynamic worksheet.
3. Open the .html just exported with a text editor and copy the <applet> section.
4. In SAGE notebook: Data> Upload the .jar and .ggb files just exported.
5. In SAGE notebook: Edit> Paste the <applet> section.
6. In the <applet> section, change codebase="./data/", you can also set some of the flags to true.
7. Save changes, and you're done.
Vim filetypes To get Vim to use Python syntax highlighting, indentation, and so on for .sage files, put the following in $VIM/filetype.vim:

{{{augroup filetypedetect

au! BufRead,BufNewFile *.sage,*.spyx,*.pyx setfiletype python

augroup END }}}

If you one of...[http://www.gnu.org/software/emacs/ those people] you'll want to visit http://www.sagemath.org/emacs/.

Autocompletion for the bash shell So, you'd like bash to autocomplete Sage files, but you want to somehow exclude those .py files that have been autogenerated by Sage. Here's a snippet that will do that for you. Put this somewhere where it will get sourced, such as your .bashrc, .bash_profile, or whatever. Often bash is set up so that it will automatically pull in completions defined in ~/.bash_completion. Here's the code:

{{{_sagecomp() {

local cur files
- COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}"
  files="(compgen−odirnames−X′!*.@(sage|?(s)pyx|py)′−f{cur})" if "$files" then
  - COMPREPLY=(You can't use 'macro parameter character #' in math modefiles))
  fi

} complete -F _sagecomp sage }}}
