3312 | 9 " |
271 | 10 " Empty .m files will automatically be presumed as Matlab files |
11 " unless you have the following in your .vimrc: | |
12 " | |
13 " let filetype_m="mma" | |
14 " | |
25773 | 15 " I also recommend setting the default 'Comment' highlighting to something |
271 | 16 " other than the color used for 'Function', since both are plentiful in |
3312 | 17 " most mathematica files, and they are often the same color (when using |
274 | 18 " background=dark). |
271 | 19 " |
20 " Credits: | |
21 " o Original Mathematica syntax version written by | |
22 " Wolfgang Waltenberger <wwalten@ben.tuwien.ac.at> | |
23 " o Some ideas like the CommentStar,CommentTitle were adapted | |
24 " from the Java vim syntax file by Claudio Fleiner. Thanks! | |
25 " o Everything else written by steve <layland@wolfram.com> | |
26 " | |
3312 | 27 " Bugs: |
28 " o Vim 6.1 didn't really have support for character classes | |
829 | 29 " of other named character classes. For example, [\a\d] |
30 " didn't work. Therefore, a lot of this code uses explicit | |
3312 | 31 " character classes instead: [0-9a-zA-Z] |

35 " fix nesting | |
