CP437 tools

A small collection of tools to handle CP437 files.

Commands

cp437-to-txt

Simply strips metadata and maps CP437 to UTF-8. Takes an optional argument to the output file, but defaults to showing the result in the terminal.

cp437-to-png

Renders the CP437 as a PNG image. Takes an optional argument to the output file, but if not given it allows piping to other programs such as imagemagick.

lib

While not intended for use as a library, it may still prove useful. Be warned though that no guarantees are made about the stability of the API.

Development

The repo comes with a nix flake, so simply type nix develop and you'll have a bash terminal with all tools needed for building this codebase.

You have an example file for simple tests (the same used for the screenshots above), but if you need more:

$ nix build '.#test_files'
$ ls ./result/
comments.ans  large.ans  meta.ans  simple.ans
