Lemonade 0.01 An Lalr Parser Generator for "D"
Based on Lemon 1.0
Ref: http://www.hwaci.com/sw/lemon/
With some modifications:
1. Generate D code (:-)
2. C style preprocessor integrated to allow
preprocessing of generated D file.
3. ameliorations to some part of the code
For example:
Each item of production in grammar, can have
an alias. THis alias can be use in the code
executed when reducing the rule.
Using the alias is a lot more fun thant the
$n of yacc parsers.
The "translateCode" function was doing a terrible job
by replacing all an every occurence of the alias in
the code. Which was not ok when the alias was inside
a string. Fixed.
4. Some others things that will be documented later.
The zip files contains all sources (except the code
for the preprocessor. Will be added later)
Compiled with Visual C++ 6.0
There is also a small example, which works.
Documentation for Lemon is available ont the site
of the author.
There is a SourceForge project with somes examples
of Lemon usage.
S/F: http://souptonuts.sourceforge.net/
See: Lemon Parser Tutorial
"Lemon is a compact, thread safe, well-tested parser generator
written by D. Richard Hipp. Using a parser generator, along with
a scanner like flex, can be advantageous because there is less
code to write. You just write the grammar for the parser. This
article is an introduction to the Lemon Parser, complete with
examples. "
More to come ( eg: RE2D, made from RE2C )

This is pretty nice. Where can I find the template file you used to generate
ex01.d?

This template both use D debug(...) and ifndef NDEBUG to delimit debug code. That won't stay that way. To produce ex01.exe: C:\> lemond ex01.y C:\> dmd ex01.d C:\> ex01 RESULT: 3

Did somebody build Lemonade under unix with gcc 4.1.2? I had to change somt things. tnx christoph Carlos wrote:Joey Peters wrote:This is pretty nice.

"Carlos Smith" <carlos-smith sympatico.ca> : Did somebody build Lemonade under unix with gcc 4.1.2? : I had to change somt things. Christoph, Hey, now that's a surprise! I was abolutely convince that nobody was actually using Lemonade ! I have gcc 4.1.2 on Ubuntu feisty. I will try to buil Lemonade tonight. Carlos

Hi again, I just compiled Lemonade on Ubuntu. The original Lemon do generate parsers with imbedded #directives. I did not completely eliminated those #directives in Lemonade. DMD has no preproc. So i decided to add one to Lemonade. The 2 zip files attached to this post (and mailed to you in a separate email), are ulemon.zip - the parser generator. ucpp.zip - the C preprocessor modified to process D code. I tested it. it work 98% ok. the 2% is related to the preprocessing phase. The cpp( ) call at the end of the main( ) in Lemonc, does not work. (It was working under Windows. This is my 1st prog on Unix) I will rework on this later, In the meantime you can play with it or fix the problem yourself. Carlos

Hi all! I created a project for lemonade on Berlios: http://lemonade.berlios.de I took lempar.d from carlos und ported lemonade.c fresh from sqllite repository. I left it in one file like lemon.c to make it easier porting bugfixes from lemon.c. carlos: I oversee to integrate some of youre improovemends, I hope you'll find some time to reintegrate. On the News page there are still some points to do.: e.g. %extra_argument in the Parse(...) function cu christoph Carlos Smith Wrote:Hi again, I just compiled Lemonade on Ubuntu.
