--- of making a compiler for some much simplified c-like language.
The Language is so-called "C minus minus" language, most of the test cases are alike to the ones of NJU Compiler Principle Course.
It's syntax is so limited that I have to rewrite a new lexer and parser in just about 6 hours in the first day to complete this report.
Can count this as a speedrun, satisfied.
Added options to just dump lexical tokens only, and to dump ast in m-expr, run with --help to see these options.
This project is done under OCaml, the ultimate answer for compiler principle and any text processing problems, famous for Coq.
you can build the main program with command:
dune buildThe build product is _build/default/bin/main.exe, though suffixed with .exe, it is actually an ELF 64-bit LSB pie executable, x86-64, for GNU/Linux 4.4.0, with debug_info, not stripped on my Arch Linux x86_64.
Of course, you can build and run it directly in one command:
dune exec cph <filename>where <filename> stands for your .cmm file.
There is a shell script plot-ast.sh to plot ast graph in PNG format, and an automated script run-all.sh which plots all .cmm files under directory input-examples/inputs/, a .log file will be generated for all errors, and plots will be at the same directory of inputs.
