It's really not on-topic for here, but there's really no way to tell
without line 349 and possibly context around it

A qualified guess is that the symbol on the left hand side of line 349
was declared as token earlier. But, on the left hand side of a grammar
rule, only non terminal symbols make sense. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi,
I am searching for the best lex and yacc combination (or something similar)
that can be used in combination with C++ and that can contain C++ code. I
have the regular flex/bison port working but then I, of course, can't use
C++ constructs in the actions.
I have tried spirit although I could make a simple command line parser
(after too many hours), creating a parser tree with it was not possible in
an easy way (the compiler choked...

Hi.
I was wondering how can I access the yacc functions?
because when use a normal yacc function such as
qstring {
yylval.string = strdup(yytext+1);
if(yylval.string !='"')
warning("Undeterminated Character strig",(char
*)0);

This might be off topic but can someone give me a quick run down on why
tools like lexx/yacc/bison are usefull ?
I know what there used for but not sure when they should be used and where ?
Thanks.

Hi!
We are finding ourselves in a situation where we have to parse
several more or less free format text files.
In the past, on linux, we had flex and bison for generating
very fast parsers for these files.
Is there any equivalent in the visual studio world?
Lots of Greetings!

Hi,
I am working on a school project where we use lex/yacc to write a compiler
for a fictional (Java-like) language. I have handled all the details about
the yacc and lex files, but I still have a question regarding the dynamic
memory allocation for strings. When the lex file encounters a variable
name, I want it to pass this to yacc through yylval, and then
retrieve it to add to a syntax tree. For this purpose, I wrote the
following...

Hi everybody!
I am using lex and yacc to write a vhdl to systemc converter.
Lex simply reads the input file and yacc implements grammar and
translation.
I'd like to be able to make yacc able to command lex to stop reading
the current file and starting reading another file, when the inclusion
syntax is reached.

If the goal is to take a 1-dimensional package of text and produce a
tree data structure that is easy to understand and manipulate, and
then write C/C++ code that works with that tree - does lex/yacc suit
that purpose - i.e. kind of like a tree-manufacturing C library? Or is
it for producing a compiler/interpreter the internals of which a new C/
C++ program cannot so easily work with?
