4 * --------
5 * Author: Josh Ventura (JoshV10@gmail.com)

7 * Release Version: 1.0.9.1
8 * Date Started: 2010/12/14
9 *
10 * YAML language file for GeSHi.
11 *
12 * YAML gets hairy sometimes. If anything needs fixed, drop me an email and
13 *      I'll probably spit up on it. This is, in general, not a long format.
14 *
15 * CHANGES
16 * ---------
17 * 2010/12/14
18 *  - Started project in rage over GML support but not YAML support. WTFH?
19 * 2010/12/15
20 *  - Submitted to Ben.
21 *
22 * TODO (not updated since release)
23 * ----------------------------------
24 *  -  Field testing and necessary corrections: this grammar file is usable, but not
25 *     completely accurate. There are, in fact, multiple cases in which it will mess
26 *     up, and some of it may need moved around. It is the most temperamental parser
27 *     I have ever associated my name with. Points of interest follow:
28 *   *  Improvised support for | and >: since PHP offers no variable-width lookbehind,
29 *      these blocks will still be highlighted even when commented out. As it happens,
30 *      any line ending with | or > could result in the unintentional highlighting of
31 *      all remaining lines in the file, just because I couldn't check for this regex
32 *      as a lookbehind:  '/:(\s+)(!!(\w+)(\s+))?/'
33 *      If there is a workaround for that, it needs implemented.
34 *   *  I may be missing some operators. I deliberately omitted inline array notation
35 *      as, in general, it's ugly and tends to conflict with plain-text. Ensuring all
36 *      highlighted list delimiters are not plain text would be as simple as checking
37 *      that they follow a colon directly. Alas, without variable-length lookbehinds,
38 *      if there is a way to do so in GeSHi I am unaware of it.
39 *   *  I kind of whored the comment regexp array. It seemed like a safe bet, so it's
40 *      where I crammed everything. Some of it may need moved elsewhere for neatness.
41 *   *  The !!typename highlight needs not to interfere with ": |" and ": >": Pairing
42 *      key: !!type | value is perfectly legal, but again due to lookbehind issues, I
43 *      can't add a case for that. Also, it is likely that multiple spaces can be put
44 *      between the colon and pipe symbol, which would also break it.
