Docker container for running rdmd

master

This docker image provides the current version of the rdmd compiler of the D programming language. The container takes source code encoded as Base64 on the command line and decodes it internally and passes it to rdmd. The compiler tries to compile the source and, if successful, outputs the program's output. Compiler errors will also be output, to stderr.

This container is used in the dlang-tour to support online compilation of user code in a safe sandbox.

Usage

Run the docker container passing the base64 source as command line parameter:

> bsource=$(echo 'void main() { import std.stdio; writefln("Hello World, %s (%s)",  __VENDOR__, __VERSION__); }' | base64 -w0)
> docker run --rm dlangtour/core-exec:dmd-nightly $bsource

Hello World, Digital Mars D (2074)

> bsource=$(echo 'void main() { import std.stdio; writefln("Hello World, %s (%s)",  __VENDOR__, __VERSION__); }' | base64 -w0)
> docker run --rm dlangtour/core-exec:ldc $bsource

Hello World, LDC (2072)

Stdin

$ bsource=$(echo 'void main() { import std.algorithm, std.stdio; stdin.byLine.each!writeln; }' | base64 -w0)
$ bstdin=$(printf 'Venus\nParis\nMontreal' | base64 -w0)
$ docker run --rm dlangtour/core-exec:dmd $bsource $bstdin
Venus
Paris
Montreal

Custom compiler arguments

$ bsource=$(echo 'void main() { import std.stdio; version(Foo) writeln("Hello World"); }' | base64 -w0)
$ DOCKER_FLAGS="-version=Foo" docker run -e DOCKER_FLAGS --rm dlangtour/core-exec:dmd $bsource
Hello World

Colored output

$ bsource=$(echo 'void main() { import foo; version(Foo) writeln("Hello World"); }' | base64 -w0)
$ DOCKER_COLOR="on" docker run -e DOCKER_COLOR --rm dlangtour/core-exec:dmd $bsource
