10 " Adapted from indent/perl.vim by Rafael Garcia-Suarez <rgarciasuarez@free.fr> |
| 2152 | 11 |
| 12 " Suggestions and improvements by : | |
| 13 " Aaron J. Sherman (use syntax for hints) | |
| 14 " Artem Chuprina (play nice with folding) | |
| 15 " TODO: | |
| 16 " This file still relies on stuff from the Perl 5 syntax file, which Perl 6 | |
| 17 " does not use. | |
| 18 " | |
| 19 " Things that are not or not properly indented (yet) : | |
| 20 " - Continued statements | |
| 21 " print "foo", | |
| 22 " "bar"; | |
| 23 " print "foo" | |
| 24 " if bar(); | |
| 25 " - Multiline regular expressions (m//x) | |
| 26 " (The following probably needs modifying the perl syntax file) | |
| 27 " - qw() lists | |
| 28 " - Heredocs with terminators that don't match \I\i* | |
| 29 | |
| 30 " Only load this indent file when no other was loaded. | |
