Tutorials on writing yacc code online use single quotes for semicolons, and other characters: \';\'\'+\'\'-\' (et开发者_如何学Cc)
So I have this definition in a header file (actually the y.tab.h file): typedef enum yytokentype { TOKEN_UNKNOWN = 1000,
My lex file has: word [^{}\"=,\\t\\n@\\\\ ]+ \\{{ return(LBRACE); } \\}{ return(RBRACE); } {word}{ yylval = yytext; printf(\"WORD=%s\",yytext); return(WORD);
So I have a yacc file which gives the required yy.tab.c when I compile it, but when I use cc or gcc to compile the output file with the library -ly, it says ly not found.
if write 1=a in the sample c program, it doesnt detect it as an error. How do i solve this problem? Also how do i do global and local scope of variables. Thanks if anyone can solve it
We\'re writing a compiler for Al Aho\'s compilers class, and we\'re considering the following code for the generation of our AST. Here is some background. We want to implement scoping rules as a stack
I know how to make YACC generate an AST, but how do you actaully get it? I mean, how do you actaully get t开发者_运维技巧he value of the root node from YACC?Yacc only gives you back one node at a time
I\'m creating a byacc program to parse some input, and I\'m having trouble resolving shift/reduce conflicts, in this case, how could I tell byac to always shift?
I have an application using sockets.. a client and server program like mySql.. I am sending queries from the client to the server where the parser resides....
I\'m having Lex and YACC files to parse my files (.l file and .y file). How to compile those files and how 开发者_运维问答to make equivalent .c file for them in windows platform?As for today (2011-04
