moo programming language

This image is a part of esolang-box 2.4.0.

About

esolang-box project aims to provide easy and normalized interface for many (currently 227 (!)) programming languages by Docker, especially to uncommon esoteric programming languages.

The implementation and interpreter of language moo is included in this image and can be invoked by the simple one command moo. (it's also an alias of script command, so you can use either.)

This script accepts standard input as the input of program and the first argument as program code file. The output of the script will be printed into standard output. This convension is shared between all esolang-box images, so you can use another language easily.

Usage example

Run a single moo script

Supposing you have hello world script hello.moo in the current directory like this:

$ cat hello.moo
33 100 108 114 111 119 32 44 111 108 108 101 72ooooooooooooo

You can execute it with the following command:

$ docker run --rm -v "$PWD":/code:ro esolang/moo moo /code/hello.moo
Hello, world!
Processing input
$ docker run -i --rm -v "$PWD":/code:ro esolang/moo moo /code/hello.moo < input.txt
Debug code with shell
$ docker run -it --rm -v "$PWD":/code:ro esolang/moo sh
# moo /code/hello.moo
Hello, world!
Observing usage of exec syscalls

esolang-box 2.4.0 supports tracing of execve and execveat syscalls by strace command. Setting STRACE_OUTPUT_PATH environment variables and enabling ptrace will produce strace log to the specified path.

$ docker run --cap-add=SYS_PTRACE --rm -v "$PWD":/code --env STRACE_OUTPUT_PATH=/code/strace.txt esolang/moo moo /code/hello.moo
Hello, world!

Some considerations:

Docker Pull Command

docker pull esolang/moo
