New Revision: 4830
URL: http://svn.gna.org/viewcvs/warzone?rev=4830&view=rev
Log:
Add a new bison/yacc parser: level_parser.y:
* Change level_lexer.l:
* Use lev_lval to return token-data in (instead of global vars)
* Use strdup() to return strings to the parser and let the parser take care
of memory clean-up (through Bison's %destructor directive)
* Use the token constants as generated by Bison (instead of our own custom
enum)
* Rip out the custom state machine-like level parser from levels.c (was
function levParse)
* Remove all global variables associated with this parser
* Remove the LP_* enum which was only used by this parser
* Move function lev_error to level_parser.y
* The new parser provides more verbose error messages if parsing fails
NOTE: The previous state machine-parser actually maintained state in two
variables, so it was rather overly complex (quadratic complexity if you like)
