Seeking Advice: Writing a parserby Flame (Deacon)
|on Feb 08, 2002 at 04:27 UTC||Need Help??|
Flame has asked for the
wisdom of the Perl Monks concerning the following question:
Well, bored out of my mind earlier today, I decided that I wanted to reach into the realm of math for a while. Thus was born the concept behind Math::ParseEquasion (Temp-name until I can come up with something better)
Now that I have the idea though, I'm stuck with a few serious problems. Most significant is that I have no clue how to write a parser. So to start with, can anyone suggest any particularly good parsing modules I should examine?
Now, basically this is the way I'm aiming to have it work:
That little bit should have parsed it into a tree resembling this:
Hopefully that explained my goals well enough.
To wrap up, I ask that if anyone has any advice or suggestions, please post them. Although I did a search for something similar to this, and didn't find it, that doesn't mean it's not there, so if someone has already written something to do this, please say so.
