I am using vim together with the pluging python-jedi. I would like to edit my .sage program with vim to but the filetype .sage is not recognized by the plugin as python's file (where the content is in python).

How can I associate .sage files to the jedi plugin ?

Answer 1

Add to ~/.vim/ftdetect/sage.vim (create if not present):

au BufNewFile,BufRead *.sage setfiletype python
