64fcb6b0b7 Traits for function templates working! Need to finish for objects and specilizations, and I think also else statements. 2014-07-18 08:52:15 -07:00

22fbd61360 Fixed a pretty bad error in isNullable logic, I must have been tired. Also, edited grammer to support a[n].b, which was previously done with wrong operator precedence so that that construction was illegal. vector.krak still doesn't quite parse, but that's because of some error with if (!name) which I will fix later. Bedtime. 2014-07-02 01:18:27 -07:00

03770028ad Fixed some bugs in Parser::firstSet and added a bit of caching. It still doesn't work quite right, though, there's some problem with nullable left recursion. However, it's better than it was, and I need to go to bed. More work later. 2014-06-30 01:57:50 -07:00

62933af8f8 Basic structures work, prep work for function pointers and other stuff,a couple of bugs fixed. 2014-01-19 18:20:52 -05:00

53b45f360d Now generates for all files that have been imported. CGenerator uses this to generate all files AND a shell script with the compile command to compile the generated C file. 2014-01-01 17:29:19 -06:00

dbf1820428 Can import other files now. (in same directory, use filename without .krak file extention) Right now, still need to compile both files with kraken. 2013-12-31 23:43:49 -06:00

935cc6f968 Added generator-dependent compilation and simple passthrough that allows us to have non-cheated emitted, printing c-code for the first time! (no typechecking or anything yet, but we'll get there). It's also still rough. 2013-12-22 01:34:59 -06:00

f273deaedc FINALLY fixed an error that took weeks. Turned out that the ParseRule was shallow copied, and the lookahead was not copied correctly. So it got extended and thus skipped over the state when it should have been redone. 2013-12-18 18:05:21 -06:00

77f2b0a3e5 Lot's of work on a CGenerator, AST and language improvements 2013-11-01 02:52:18 -04:00

b9ffe33d0b Made Symbol always stack, not heap, allocated. Finally fixed bugs with ASTTransformation. 2013-10-02 03:15:20 -04:00

d1f2ba5fc8 Fixed the bug! Probabally other bugs too. 2013-08-26 15:37:49 -04:00

d21f521266 Have a nullableParts generator now. It works for simple cases and may work for advanced cases, but more testing is required to ensure full usability. 2013-08-13 14:01:53 -04:00
Nathan Braswell
3a5d94caaa Started adding the nullable parts machinery. Also started to fix addStates for RNGLR and null reductions so it only truncated the rule to what had already been parsed, but now it looks like it maybe shouldn't truncate at all and use pointer position for length. However, I have to go to bed and will pick up later. 2013-08-12 00:02:50 -04:00

af0c1f0a81 Fixed some more DOT generation stuff. 2013-08-11 01:15:26 -04:00
Nathan Braswell
ea42cb5bc7 The out of orderness was actually the fault of the dot graphing program, not Kraken, so that's good news. DOT generation has also been modified so that it properly inserts \n's (actually \n's) where line returns are so that dot can parse the \n and not the line return. 2013-08-11 00:37:12 -04:00

b292bd15ae Now parses into parse trees! Still does not add the null-reducable trees, and there are a few ordering mistakes, but it works. 2013-08-10 18:24:37 -04:00

9f3370481e Fixed all syntax errors, but NULL crops up where it shouldn't. Checks for it as stop-gap, creates very truncated trees. Does run, and still correctly accepts. Calling it a night. 2013-08-09 04:39:43 -04:00

31d7c02ef9 Finished writing first code for turning the RNGLR recognizer into a parser. Doesn't compile yet, needs lots of bugfixing, but I'm calling it a night. 2013-08-08 02:44:17 -04:00
Nathan Braswell
680d978dcb Problem was actually in grammer, fixed it. Also made identical rules with different lookahead merge. Now just started on creating parse trees. Stopping for night. 2013-08-06 01:49:45 -04:00

9460bacf1c Fixed some problems with grammer loading of null rules and rules non-terminals and terminals that had the same name 2013-08-04 14:24:20 -04:00
Nathan Braswell
d5b33efb22 Null rules work in RNGLR now, but there seems to be a bug where somehow some states/rules get no lookahead. 2013-08-02 15:21:42 -04:00

49d149bc1f RNGLR Recognizer now works for grammers without null rules. 2013-08-02 02:47:01 -04:00

9887555dd5 Have almost got the RNGLR recognizer. Something is wrong with the GSS, I think when it's built. It seems to sometimes have parents as children, or something. 2013-07-31 23:51:05 -04:00

733fe1c08d Changed Table to store vectors of actions, changed Parser appropriately. 2013-07-28 23:48:10 -04:00

6d7b38a03b More work towards RNGLR. First, NodeTree is now a template. Second, I've started writing the actual GLR parser and GSS and other things, but am still in the first write process. 2013-07-28 19:45:08 -04:00
