vim support

[Peng Yu]

Hi,

I followed the following tip to set up vim for sage. But I don't see
syntax highlight nor correctly auto indentation. Has anybody
successfully configured vim for sage?

http://wiki.sagemath.org/Tips

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

Do Python syntax high-lightings work in your vim?

What I use is:

autocmd BufRead,BufNewFile,BufWritePost *.sage set filetype=python
autocmd BufRead,BufNewFile,BufWritePost *.spyx,*.pyx set filetype=python.c

I've seen that tip, but it's not really close to a solution, it's just a dirty hack that has nothing to do with Sage (Python syntax != Sage syntax, there's plenty of extra stuff in Sage).

What I did for now is just exporting Sage keywords (there are corresponding built-in functions for that) into Python syntax file, so I at least get highlight for all functions and methods. You can find the file here http://xsnippet.org/359006/. 

I'd prefer having Sage syntax suger highlighting as well (like z.<x> = ...), but didn't bother to implement it yet.

It's not really a hack. The syntax and functions in Sage are a superset of what is there in python. So, it makes sense to set it to python. Of course, it would be nice to have Sage functions properly highlighted, but as a first step the commands below work. You don't get syntax highlighting for Sage functions, but you do get stuff properly indented.

By being a hack, I mean that the setting has nothing to do with "Vim support of Sage". It's  just forcing vim to interpret Sage files as Python files, since sage is built upon Python and has similar (though, not identical) syntax. Relatively to vim, it thinks that it just works with Python. So one can't really call it a "Sage support".

That's true. But is anyone saying vim supports Sage syntax?

Nope, but that's the problem :) Would be nice to have full Sage syntax support (and autocompletion — sweet dreams :) since I'm pretty sure many of those who use Sage also use Vim. Unfortunately currently I'm not too good in vimscript to write a good syntax file or completion plugin. But after my vacation is over I might give it some time if no good solution will come up before.
