TeX (plain) 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 TeX (plain) is included in this image and can be invoked by the simple one command tex. (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 TeX (plain) script

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

$ cat hello.tex
\write0{Hello, World!}
\end

You can execute it with the following command:

$ docker run --rm -v "$PWD":/code:ro esolang/tex tex /code/hello.tex
Hello, World!
Processing input
$ docker run -i --rm -v "$PWD":/code:ro esolang/tex tex /code/hello.tex < input.txt
Debug code with shell
$ docker run -it --rm -v "$PWD":/code:ro esolang/tex sh
# tex /code/hello.tex
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/tex tex /code/hello.tex
Hello, World!

Some considerations:

Docker Pull Command
