[PROPOSED] Replace ERD (Haskell) with erd-go

[barthel]

As part of asciidoctor/docker-asciidoctor#51 I have been trying to create a multi-platform Asciidoctor Docker image.

In doing so, erd (https://github.com/BurntSushi/erd) was a challenge, as there is only one x86 platform variant.

To remove this limitation, I looked at erd-go (https://github.com/kaishuu0123/erd-go/) and included it.
Since it supports the same CLI parameters, replacing the executable was enough.

To further promote platform independence, I would like to propose an official switch to or support of erd-go.

erd was introduced with #118

WDYT? @pepijnve @mojavelinux

That makes a whole lot of sense. Should simplify (and significantly shorten) the CI builds as well. Installing the Haskell environment eats up a lot of time just for erd. Referenced PR should make this work already.

Used and testable via Docker Image https://hub.docker.com/r/uwebarthel/asciidoctor/

Github project (Dockerfile): https://github.com/barthel/docker-asciidoctor

Hello folks, sorry for being a party crasher bu you might want to look at asciidoctor/docker-asciidoctor#343 (comment) .

It is hard to evaluate the safety of erd-go as it has not been updated since Feb. 2021, before the Travis credentials leaks.
If at least we can help the author by switching their CI to GitHub Actions and have a new release fully from GitHub, that would be a first trustable step.
Eventually forking the repository to asciidoctor (if someone agrees to maintain it)?

A cleanup of the golang version and its gomod version (dependabot) would also clearly help.

@barthel Are you up to the challenge?

[pepijnve]

@dduportal I understand the concern. Not really an issue for the diagram extension itself since it supports both the Haskell and Go version now preferring the former over the latter.

[barthel]

@dduportal You are not a party chrasher. Security concerns are important and valid at any time.

The goal of using erd-go is to use a platform independend tool.
As a consequence, erd-go will be compiled for each platform and no pre-compiled executables are used.

Let's discuss in asciidoctor/docker-asciidoctor#343 (comment)

Challange accepted for a more than less platform independent Asciidoctor.
