POAdvice on Python Parser Generators
text
Body
copied!<p>Hey guys, this is my first question here on Stack Overflow and I was wondering if I could ask the advice of people who know a bit more about Python and Parser Generators than I do.</p> <p>I've been given a task where I have to create a parser for a simple C-like language. I can use any programming language and tools I wish to create the parser, but I'm learning Python at the same time so it would be my prefered choice.</p> <p>There are a few restrictions my Parser has to follow. Firstly, it must be able to read in a text file that contains the following information:</p> <pre><code>kind1 : spelling1 kind2 : spelling2 kind3 : spelling3 . . . kindn : spellingn </code></pre> <p>Where each kind and spelling refer to the token type and value of the language. This file is the result of putting a sample of code through the language's lexical analyser.</p> <p>Secondly, I must be able to customise the output of the parser. Ideally I would like to output a file that has converted the kind:spelling list into another sequence of tokens that would be passed to the language's compiler to be converted into MIPS Assembly code. Here's a little example of the kind of thing I would like the parser to be able to produce:</p> <pre><code>%function int test %variable int x %variable int y %begin %if %id y , %id x > %do %begin %return %num 0 %end %return %num 1 %end </code></pre> <p>It would be a great help if someone could advise me on existing Python Parser Generators and if I'd be able to achieve the sort of thing I'm looking for in the above examples.</p>
