Example parsers to learn how to write them [closed]

I am looking for source codes of parsers and/or parser generators that could be studied in order to develop further, my skills that I acquired during a school course. Do you know any recommendable parsers of any type?

Solution 1:

You should know how to build recursive descent parsers by hand. Here's an SO link to a quick lesson on how to do this: https://stackoverflow.com/a/2336769/120163

If you want to understand how recursive descent parsers can be constructed automatically, you can read a paper (and see a tutorial) on MetaII at this link: https://stackoverflow.com/a/1142034/120163

Solution 2:

• Bison is a classical example (C/C++).
• Pyparsing is a great module, and it is very easy to use (Python) .
• Lemon is very easy to use (C++).

Check the examples, and good luck.

Edit:

I guess I should comment. A parser is a program which processes an input and "understands" it. A parser generator is a tool used to write parsers. I guess you mean you want to learn more about generating parsers, in which case, you should refer to the documentation of parser generators (all of the above).
