Possible to run psc-ide-server, etc. in docker? about purescript-ide-purescript-core HOT 7 OPEN

Firstly, do you mean to run psc-ide-server rather than the combined purs executable that recent compiler versions use?

The code for launching the IDE server is here: https://github.com/kRITZCREEK/purescript-psc-ide/blob/master/src/PscIde/Server.purs

You could write a wrapper script to start a server in docker, but you'd need to do a dance to ensure that works with the randomly chosen port number - instead I'd suggest starting the server yourself.

So e.g. start a purs ide server -p 54321 in docker exposing some port 54321, and echo -n 54321 > .psc-ide-port before starting. The cwd of the server has to match the project directory, so I'd imagine that may be an issue to running inside docker in general.

How are you consuming this package?

I picked the first ps-docker image I found (https://github.com/Risto-Stevcev/purescript-docker) and ran with it, seems to be using recent enough PS but I didn't see the purs executable.

Thanks! Starting the server separately should be a viable solution, will try that.

The use case is using VSCode with PS in a class setting and attempting to provide an OS-agnostic turn-key development environment to the participants. Docker mounts the project directory as a volume. If file paths that VSCode and PS executables see have to match this could be a problem, but an addressable one, I think.

This package: not consuming it, was just poking around the plugin code to see how the IDE server is started and found this.

Looks like it's ultimately easier to install npm natively and do it the regular way.

Apologies for obscurity! I was referring to my use case and the original idea of having students work in VSCode/Atom with a self-contained development environment (with PS, node for running web servers, etc.) instead of installing the npm/node/PS stack natively on their platform. The IDE server was just the first stumbling block I encountered.

TL;DR the attempt to simplify environment setup using VSCode and docker was flawed and this issue can be closed or become a low-priority feature request.

No problem, I'll certainly leave the issue open as it's a valid use case, just has several issues to solve. I had a similar experience doing Advent of Code in multiple languages, getting a compiler running inside Docker was straightforward but tooling assumes a native installation

Using the docker image from https://github.com/codewars/purescript this works perfectly for me:

docker run --name pscript --net=host -v $PWD:/$PWD -it --entrypoint bash  --rm ghcr.io/codewars/purescript -c "cd $PWD; purs ide server -p 1234"

I have to set the extension settings to use port 1234 and also change the build command to docker exec -it pscript bash -c "cd $PWD; spago build --purs-args --json-errors".
