9 " |
| 4437 | 10 " Version 13.0 |
| 11 " - Extended the option omni_syntax_group_include_{filetype} | |
| 12 " to accept a comma separated list of regex's rather than | |
| 13 " string. For example, for the javascript filetype you could | |
| 14 " use: | |
| 15 " let g:omni_syntax_group_include_javascript = 'javascript\w\+,jquery\w\+' | |
| 16 " - Some syntax files (perl.vim) use the match // syntax as a mechanism | |
| 17 " to identify keywords. This update attempts to parse the | |
| 18 " match syntax and pull out syntax items which are at least | |
| 19 " 3 words or more. | |
| 20 " | |
| 21 " Version 12.0 | |
| 22 " - It is possible to have '-' as part of iskeyword, when | |
| 23 " checking for character ranges, tighten up the regex. | |
| 24 " E688: More targets than List items. | |
| 25 " | |
| 3996 | 26 " Version 11.0 |
| 4437 | 27 " - Corrected which characters required escaping during |
| 3996 | 28 " substitution calls. |
| 29 " | |
| 3920 | 30 " Version 10.0 |
| 4437 | 31 " - Cycle through all the character ranges specified in the |
| 3920 | 32 " iskeyword option and build a list of valid word separators. |
| 3996 | 33 " Prior to this change, only actual characters were used, |
| 34 " where for example ASCII "45" == "-". If "45" were used | |
| 35 " in iskeyword the hyphen would not be picked up. | |
| 3920 | 36 " This introduces a new option, since the character ranges |
| 37 " specified could be multibyte: | |
| 38 " let g:omni_syntax_use_single_byte = 1 | |
| 4437 | 39 " - This by default will only allow single byte ASCII |
| 3920 | 40 " characters to be added and an additional check to ensure |
| 41 " the charater is printable (see documentation for isprint). | |
| 42 " | |
| 43 " Version 9.0 | |
| 4437 | 44 " - Add the check for cpo. |
| 3920 | 45 " |
| 3224 | 46 " Version 8.0 |
| 4437 | 47 " - Updated SyntaxCSyntaxGroupItems() |
| 3224 | 48 " - Some additional syntax items were also allowed |
| 49 " on nextgroup= lines which were ignored by default. | |
| 50 " Now these lines are processed independently. | |
| 51 " | |
