Easily execute Swift programming language
86
This image is a part of esolang-box 2.4.0.
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 Swift is included in this image and
can be invoked by the simple one command swift
.
(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.
Supposing you have hello world script hello.swift
in the current directory like this:
$ cat hello.swift
print("Hello, World!")
You can execute it with the following command:
$ docker run --rm -v "$PWD":/code:ro esolang/swift swift /code/hello.swift
Hello, World!
$ docker run -i --rm -v "$PWD":/code:ro esolang/swift swift /code/hello.swift < input.txt
$ docker run -it --rm -v "$PWD":/code:ro esolang/swift sh
# swift /code/hello.swift
Hello, World!
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/swift swift /code/hello.swift
Hello, World!
Some considerations:
--cap-add=SYS_PTRACE
(especially you must not use it with Xenial).docker pull esolang/swift
