Pycparser Alternatives

pycparser reviews and mentions

• Easy-to-use open source C preprocessor library?
  1 project | /r/c_language | 3 May 2023

  In python, we have pycparser https://github.com/eliben/pycparser to parse C files into a tree.

• What package is used to analyze C code?
  1 project | /r/learnpython | 22 Dec 2022

  I found pycparser which can probably do what you need, but it might not be very easy to use.

• Complete C99 parser in pure Python

• Cake: C23 Front End and Transpiler C23 – C99

  You can also use pycparser[0]. It is fully compatible C99, but be careful it doesn't support gnu extensions (like attributes, #indent, asm() ...). You can however work around most of them by -D defining them to empty macro in the argument.

• When do you truly know C?
  1 project | /r/C_Programming | 27 Jul 2022

  I wrote that tiny C compiler in Python and chose pycparser as the starting point. If you run C source code through pycparser it yields an Abstract syntax tree (AST) which is an in-memory, fine-grained tree representation of the C source code (for example, compound expressions are represented as binary trees that obey operator precedence rules which is extremely helpful).

• Script that detects functions written in C
  1 project | /r/learnpython | 8 Jun 2022

  The difficulty is that in c you can do all kinds of weird and wonderful things... Doing it just by a text analysis of three code is going to be difficult to say the least. You could look at something like this parser though I suspect you might get better results using some of the existing utilities out there

• Check function length in C?
  1 project | /r/AskProgramming | 21 Mar 2022

  Just find a C parser/lexer/whatever that'll handle the parsing for you. You can probably use it to determine where each function starts, where it ends, what it's called, etc.

• Anyone interested in working on a hardware (FPGA/ASIC) related project? Not a compilers person by training, looking for help.
  2 projects | /r/Compilers | 15 Jul 2021

  In terms of functionality the PipelineC project is pretty mature. But the back end implementation is hacky involves far to much reliance on a pycparser setup I dont understand (other than basic AST traversal was all needed). And as I slowly look to add not-strictly-C language concepts I would love to be working with someone who knows whats going on with compilers, syntaxes, intermediates. Some kind of Rust or C++ front end would be cool - template types and constexpr like things are something I am really missing being limited to C at the moment. I'll teach you FPGA things in return :-p
