fixed: Done in [2250]

17:51 Changeset [2250] by flaviusaetius

• trunk/lexi/src/output-c/c-output.c

Not generating the include header file directive when output is standard output: see tickt 246

16:09 Ticket #89 (enhancement) closed by kate

invalid: I don't see how we could, unless we express the trie as an FSM.

wontfix: This has nothing to do with IF()s per-se; that was just a use-case. …

fixed: Done in [2248]. Putting ARGUMENT name:ctype; in the lct file will add a …

14:30 Changeset [2248] by flaviusaetius

• trunk/lexi/src/lctlexer.c
• trunk/lexi/src/lexer.lct

Regenerating lctlexer.c and correcting a small error in lexer.lct as per 2247

• trunk/lexi/src/lexer.lct
• trunk/lexi/src/output-c/c-output.c

Adding the ability to include other components to the lexer state. In the lct file one can put a stattement of the form ARGUMENT name:ctype; All those arguments will be part of the state structure and will be initializable through the (lexiprefix)_init function. Use of this feature will happen in lexi's own lexer.lxi file in an upcomming patch

This is a refactoring of the datastructures forming Lexi's character trie. It concentrates mostly on simplifying the data forming the trie itself, rather than attempting to clean up the supporting code. Since the underlying datastructures are different, much of that supporting code is reworked neccessarily, but further excursions are kept to a minimum. In particular, I've tried to leave c-output.c alone as alone as possible.

The most significant implementation changes are:

• The trie's special-case leaf and root nodes have been removed.
• The trie's internal EOF character has been removed (stdio's EOF is used instead).
• The special-case not_in_group type has been removed.
• The gruntwork of numbering groups (and therefore the total number of groups permitted) is now moved to the output code.
• Character translations have been removed; these values are folded into the trie directly.

Side-effects are:

• EOF is no longer permitted in groups
• Empty groups are not present in the lookup table.
• Groups may now contain character \0.
• Group inversion is supported for including subsets: GROUP a = "[^b]";
