It is easy to recover the number of the dimensions. But I want to find what
are the dimensions as well. If I count the brackets, that won't give much of
information will it ?

It's not that difficult to do this sort of thing.
I almost always call the object I pass to Bison along with the parameter
for `yylex' `scanner_node' an

Basically, I want to derive information from it. For example, if I got a
matrix like [[1,2],[3,4]], I want to find the dimensions of it. The thing
is, taht I had already a pretty good function for doing this, when I had
manipulating the expression without bison. now with bison, if I want to the

A linker should be able to link object files no matter what language was
used to pro
Hi!
Let's say I have the rule
paren:
'(' expression ')'
{
}
Flex scanner has previously analyzed the string and extracted the tokens.
However, if I want the text that corresponds to this expression, for example
the "(1+2)" and not just
Finally, it was somthing really easy and stupid and had nothing to dowith
bison. I just was worred, because I don't know how much compatible C and C++
code can be.
Thanks for the help anyway :)
