Jesse Beder	43ea59a4ed	Added folded and literal scalars.	2008-06-28 20:08:21 +00:00
Jesse Beder	01ef70a6f9	Fixed complex keys.	2008-06-28 17:32:10 +00:00
Jesse Beder	c63ebbd878	Moved the simple key validation to before each token scan (plus at newlines of scalars).	2008-06-28 16:46:37 +00:00
Jesse Beder	11706abbb7	Added simple keys. ... There's a bug (and question): should we test simple keys' validity BEFORE stuff or AFTER stuff?	2008-06-28 06:36:59 +00:00
Jesse Beder	49a75b2d78	Added quoted scalars (with escaping). ... Refactored some common whitespace-parsing code in scanning both scalars. Implemented the flow collection tokens.	2008-06-27 23:11:46 +00:00
Jesse Beder	a224c7818b	Small plain scalar scanning fixes.	2008-06-27 20:54:43 +00:00
Jesse Beder	8fca02fb2a	Split off the specific regular expressions, and the specialized token-scanning functions, into their own files.	2008-06-27 19:13:03 +00:00
Jesse Beder	de29068110	Added stream input to the regular expressions, greatly simplifying the usage (in particular, we no longer have to specify the number of characters to be checked).	2008-06-27 19:07:30 +00:00
Jesse Beder	4e435b1321	Wrote a simplified regular expression parser to make life easier (it only does single matches; i.e., no one-or-more matches, etc.). ... Fixed some of the whitespace/line break matching.	2008-06-27 08:20:41 +00:00
Jesse Beder	873dbc2421	The plain scalar scanner is almost done (and it scans a simple list correctly). ... Also messed around with multiple character peeking on the input, and got something working.	2008-06-27 00:18:52 +00:00
Jesse Beder	31f7db5a0d	More simple scalar scanning.	2008-06-26 22:00:39 +00:00
Jesse Beder	a3961d047f	Continued working on scanner. ... We're now using exceptions for errors, and scanning/pushing tokens is exception-safe (using a set of "limbo tokens").	2008-06-26 19:30:11 +00:00
Jesse Beder	8ae7b48188	Started the scanner.	2008-06-26 09:05:28 +00:00
