How I pictured sammine-lang in my head

Dev

MacOS Configurations

Install llvm & catch2

brew install llvm catch2

Run

cmake -S . -B build -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE=Debug [-DSAMMINE_TEST=ON/OFF] [-DCMAKE_LINKER_TYPE=MOLD]

for configuration. We need llvm,FileCheck, and lit.

Run

cmake --build build -j 

and

cmake --build build -j --target unit-tests e2e-tests

in the project root folder to cycle through the development process.

Run

rm -rf build

to erase the build folder (similar to make clean).

Simple Demo

Compiler help

./build/src/sammine --help

Usage: sammine [--help] [--version] [[--file VAR]|[--str VAR]] [--llvm-ir] [--diagnostics]

  -v, --version   prints version information and exits
  -f, --file      An input file for compiler to scan over.
  -s, --str       An input string for compiler to scan over.

diagnostics (detailed usage):
   --llvm-ir      sammine compiler spits out LLVM-IR to stdout
