[WIP]: A path to white label friendly play-haskell

[hellwolf]

Motivation

The white labeling of play-Haskell, if made easy, can be quite an attractive tool for EDSLs, who could benefit from an easier way of onboarding/showcasing their technology to stakeholders or public audiences.

Yolc is one such use case that I was after, but the likes of copilot, clash lang, may also be of interest.

Overall, it took me approximately two to three days to hack everything live at play.yolc.dev. During the process, with the hands-on experience, I put my thoughts and proposals on how I think we could make the project white labeling easier in this PR.

Proposed changes

⚠️ Bear in mind, though, that the code itself is not ready until I mark this draft PR ready for review.

This is a draft PR documenting my "slow" process of realizing these thoughts and keeping myself accountable for my promise...

Customizing Server <-> Worker protocol

1. submit function assumes

Customizing Server

• Customizable page header
• Customizable worker commands (default is Run, Asm, Core
• Customizable example code

Customizing Worker

• Customizable resource limits, e.g. resource memory for systemd process
• Customizable worker command
• Customizable ghc version <-> builders scheme: e.g. customizable from ./builders/build-9.10.1.sh to ./builders/yolc-9.10.1.sh .
• Make mkbuildscript.sh support building from non-hackage-published local packages. In case of the EDSL project is not published to hackage.
• Customizable project template, since the EDSL project may not build from a "Main" module entirely written by the user.
