2. syntax analysis

3. semantic analysis

4. code generation

5. optimization

6. code-not-shitication

Installation

brew install crystal-lang
git clone git@github.com:forsaken1/simple-compiler.git
cd simple-compiler

crystal build simple-compiler.cr         # build compiler
./simple-compiler path/to/file.txt       # compile file without optimization
./simple-compiler -s path/to/file.txt    # returns list of tokens (scanner)
./simple-compiler -p path/to/file.txt    # returns syntax tree (parser)
./simple-compiler -g path/to/file.txt    # returns assembler code (generator)
./simple-compiler -o path/to/file.txt    # compile file with optimization
./simple-compiler -g -o path/to/file.txt # returns assembler code with optimization

crystal tester.cr # run all tests (don't work without simple-compiler)
