Is there any way, in lex (or flex), to use
a variable for the pattern to match.
Basically, I want something along the lines of this:
%{
char str[24] = "bogus_string";
%}
%%
str { /* action - with str being the string above */}
. { }
%%
One of two problems I had in mind were:
1) Taking command line arguments as my pattern matching
string.
2) Using elements of a static array of strings to be matched.
My first guess would be that this *isn't* possible (except
maybe through pre-processor magic :)).
I imagine lex would need to be able to build it's state table on
the fly to do this. However, if anyone who knows a little bit
more about lex and knows any neat tricks, I'd appreciate hearing
them.
(Please no references to books, I don't have enought time to read
all the books I have :))
Thanks.
