2012-01-10Leaf cloner.David Walter Seikel1-6/+10
2012-01-10Get rid of the comment function.David Walter Seikel2-15/+3
2012-01-10Get rid of the LSL_AST structure, it's all in LSL_Leaf now.David Walter Seikel3-119/+95
2012-01-10Move more things into the LSL_Leaf structure, and some clean up related to that.David Walter Seikel4-173/+173
2012-01-10Almost got white space and comments working. Still a bug left somewhere, I ↵David Walter Seikel5-211/+249
think it's in operations ordering.
2012-01-09Hmmm, we have a circular dependencie with the include fiels each of flex and ↵David Walter Seikel1-0/+9
btyacc generate. So run btyacc twice.
2012-01-09A little format cleanup.David Walter Seikel1-8/+5
2012-01-09Doesn't hurt, but does not fix it either. Gives me an idea though.David Walter Seikel1-2/+2
2012-01-09The other half of the comment scanner.David Walter Seikel1-3/+16
2012-01-09Moved yyerror() into the flex source. Added a count function, CHAR, STRING, ↵David Walter Seikel2-8/+34
and comment stripping. Well, half of comment stripping, it will fail without the other half. lol
2012-01-09Missed this.David Walter Seikel1-0/+1
2012-01-09Added ANSI C flex and yacc files, just for reference.David Walter Seikel2-0/+653
2012-01-09One of these days I'll get spaces to work. Another hack at it.David Walter Seikel2-5/+12
2012-01-09Implement script, and add YYVALID for statement to help with recovering from ↵David Walter Seikel1-1/+6
errors.
2012-01-09Turn btyacc debugging back on, it's fine now.David Walter Seikel1-2/+1
2012-01-09Missed a keyword.David Walter Seikel1-0/+1
2012-01-09Add most of the rest of the tokens, but ignore them.David Walter Seikel3-54/+118
2012-01-08Rearrange everything, to be consistant order.David Walter Seikel4-165/+193
2012-01-08Bite the bullet and get rid of my dreams to use enums, yacc insists on #defines.David Walter Seikel2-119/+26
2012-01-08Apparently order of these ALSO sets precedence. shrugsDavid Walter Seikel1-10/+10
2012-01-08Use character classes, some clean up. Tried to add space storing, but it ↵David Walter Seikel4-31/+46
did not work.
2012-01-08Parenthesis and statement parsing.David Walter Seikel5-8/+76
2012-01-08Parse an actual file.David Walter Seikel4-50/+130
2012-01-07Forget to save first. lolDavid Walter Seikel1-0/+1
2012-01-07More expression cleanup.David Walter Seikel2-158/+169
2012-01-07Clean up. exp -> ast. No more addExpression or outputExpression. ↵David Walter Seikel2-112/+102
Operations output themselves.
2012-01-07We don't need LSL_Expression.David Walter Seikel2-45/+12
2012-01-07Evaluate expressions using the new token table.David Walter Seikel2-155/+126
2012-01-07Make the parser more generic with function pointers and a big arse table.David Walter Seikel3-204/+209
2012-01-07No need to actually compile the LSL flex and yacc sources, they are just ↵David Walter Seikel1-10/+0
reference now. I'll be writing me own.
2012-01-07Convert the parser from dealing with just expressions, to dealing with the ↵David Walter Seikel4-237/+240
entire AST.
2012-01-06Flex performance tweaks, and other options.David Walter Seikel3-12/+17
2012-01-06Added most of the expression parser.David Walter Seikel3-33/+84
2012-01-06Precedence changes.David Walter Seikel1-2/+1
2012-01-06Remove errant empty line.David Walter Seikel1-1/+0
2012-01-06Folded this code into the rest of the C file, but forgot to remove the file.David Walter Seikel1-22/+0
2012-01-06Even more debugging stuff, and make it selectable if the parser uses ↵David Walter Seikel4-122/+207
#defines or enums for tokens. NOTE - enum does not work anyway with btyacc.
2012-01-06Add more debugging stuff.David Walter Seikel2-19/+21
2012-01-06Use the LSL_ enums for parser tokens. Some clean up and debugging.David Walter Seikel5-148/+147
OK, so the parsers prefer to make them defines instead of enums. sigh
2012-01-06Add more LSL parsing structure.David Walter Seikel5-114/+556
2012-01-05Update the not yet used real parser includes to.David Walter Seikel2-19/+13
2012-01-05Consolidate the parser includes.David Walter Seikel6-89/+75
2012-01-05Bit more cleanup.David Walter Seikel1-6/+8
2012-01-05Clean up the parser.David Walter Seikel3-142/+100
2012-01-05Remove most of the constants, we can put them in Lua globals later. Make ↵David Walter Seikel4-991/+28
the LSL parner more like the test one.
2012-01-05Added the unadulterated flex and bison source files from the SL viewer.David Walter Seikel3-0/+2751
Actually, from meta-impy, but originaly from one of the SL viewers. They actually produce C files, though some of it is C++. The resulting files wont compile without lots of C++ files from the viewer. Still, it's a step in the right direction. "btyacc: 88 reduce/reduce conflicts." might be a worry though.
2012-01-05Make the btyacc stuff a little more reentrant to match bison.David Walter Seikel1-8/+8
It's still not reentrant. lol
2012-01-05Add a simple flex + btyacc stub.David Walter Seikel9-1/+1303
Will be fleshed out soon with LSL grammer.
2012-01-05Add a compiler stub.David Walter Seikel5-3/+47
2012-01-04Move the object files out of the source directory.David Walter Seikel1-6/+7
Should do a proper out of tree build later, this is just quick and dirty for now.
