Lispy stuff
Simple lisp-ish language compiler written in C++.
Right now it doesn't compile much - it's just a parser. The end goal is to emit bytecode. The bytecode format is not decided yet.
Build
All you need is:
- CMake
- An appropriate C++ compiler
I use cmake for the build system. I prefer to build out-of-tree, here's how to build if you've never used cmake:
cd build
cmake ..
make
This will build two executables, main and test. test runs all tests
on the compiler itself
Development
I use clangd as the language server. If you want your include files to be handled
correctly, you'll need to generate compile_commands.json yourself. You can
do this using cmake:
cd build
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 ..
cp compile_commands.json ../
After this, clangd should not give you errors on every included header.
Toolchain
C++ can be somewhat error-prone, so in order to reduce the possibility of certain bugs, cmake toolchain options are provided that build the project with the undefined behaviour sanitizer and the address sanitizer.
You can build a sanitized version like this:
cd build
cmake .. --toolchain ../toolchain/sanitize.cmake
make
Catch2 testing framework is used to maintain code correctness.
Progress
Woodpecker CI/CD system is integrated. Currently using Catch2 for unit testing.
- Lexing - complete, more token types may be added as necessary
- Parsing - This is the next step.
- Optimizations -
- Emitting Bytecode - the goal.
