Wolfgang (Blub) Bumiller	4c2e5d7ebf	update old_string after a recursive preprocess call so we don't reset to a free'd vector; add recursion header/footer pragmas	2012-11-18 14:39:24 +01:00
Wolfgang (Blub) Bumiller	441a224435	Comment about why stringify is so short	2012-11-18 14:29:15 +01:00
Wolfgang (Blub) Bumiller	a014480987	Add quotes to the known control sequences... darn. Add stringification via #	2012-11-18 14:26:40 +01:00
Wolfgang (Blub) Bumiller	0330b082a2	The ftepp now always outputs into a string buffer, with -E the buffer will be dumped to stdout or the via -o specified file, without -E it'll be passed to the parser to be compiled	2012-11-18 13:33:53 +01:00
Wolfgang (Blub) Bumiller	d1373af7fc	Make -E print to stdout by default and honor -o, changed handling of source list a bit	2012-11-18 12:51:38 +01:00
Wolfgang (Blub) Bumiller	366557bbab	Since like with parsing, the preprocessor state has to be preserved across files for macros, we do that now, and with that introduce a new warning: -Wmultifile-if in case an #if spans over several command-line-provided source files (or progs.src file provided for that matter)	2012-11-18 11:54:11 +01:00
Wolfgang (Blub) Bumiller	515cafe8bd	Lexer should keep newlines in merged lines, so will the preprocessor, but therefore the lexer will replace comments with actual spaces so we don't get borken output... also don't error about redifining a macro when inside a non-outputting #if branch	2012-11-16 23:13:53 +01:00

Wolfgang (Blub) Bumiller	5b91c2af5e	Relax the preprocessor condition: # in the middle of a line also counts, but take care of builtin numbers since they use # as well	2012-11-16 21:37:34 +01:00
