It almost seems like it would be simpler to just include everything in one package. But i'm certain that it will at least flag the shift/reduce conflict.) the conflict arises in the rules I've done a couple of small projects with gplex/gppg, which are pretty straightforward reimplementations of lex/yacc in c#

I've not used any of the other tools above, so i can't really compare them, but these worked fine
Gppg can be found here and gplex here
That being said, i agree, a full lex/yacc solution probably is overkill for your problem I would suggest generating a set of bindings. Everything is going great except for one really nasty bit The language we are parsing has a sort of .
For lalr parser, i found gppg/gplex, and for ll parser, there is the famous antlr But, i want to reuse my flex/bison grammar as much as possible Is there any direct port of flex/bison for c# What lexer/parser people normally use for c#
Is there any reason for that choice?
I could go and write a big method that would use the collected tokens to figure out which leaves should be put in which branches and in the end populate a treenode object, but since gppg already handled everything by using supplied regular expressions, i was wondering if there's an easier way? Gardens point lex and the gardens point parser generator are strongly influenced by lex and yacc, and output c# code Your grammar is simple enough that i think your current approach is fine, but kudos for wanting to learn the real way of doing it This is far from a full example
The actual gppg file needs to replace the. 0 we're using gppg (essentially bison for c#) to generate a parser for a programming language The language we are parsing has a sort of implicit comparison rule, where expression expression should be interpreted as expression == expression. Here is the grammar for gppg (its a bison like compiler compiler
And that was not an echo):
When i was working in c#, i found the gppg and gplex parser/lexer generators to be perfect for my needs I'm wondering if there's something similar for the d programming language (i.e That grammar surely produced at least one shift/reduce conflict along with a warning that the production attrbt /* nothing */ is useless because of the conflict
(if that's not the case, it's because gppg doesn't provide as many warnings as bison
