Add Homebrew fomular

[hcoona]

I'd like to have asciidoctor-diagram in Homebrew fomular just like asciidoctor

[mojavelinux]

I support this idea. It could really simplify installation. Would you be willing to contribute the formula (or at least get started)?

[hcoona]

I tried by modify asciidoctor fomular but failed to get it work. We need somebody familiar with the Homebrew gem mechanism.

There is a major issue: the asciidoctor cannot found asciidoctor-diagram gem.

There is a minor issue: the asciidoctor-diagram also build asciidoctor gem although I installed it by brew install asciidoctor. As a result, there are 2 asciidoctor commands provided by asciidoctor homebrew fomular & asciidoctor-diagram fomular. (The major issue occurs for either case)

[mojavelinux]

Can you be more specific about what didn't work?

[eddiejaoude]

Was there any progress on this issue? Having installed Asciidoctor via brew, it would be great to be able to install the diagram extension the same way.

This is not something I'm working on myself. It's not clear to me what the added value is of brew install asciidoctor-diagram over gem install asciidoctor-diagram to be honest.

[eddiejaoude]

The reason why I want to install it via brew instead of gem, is for 2 reasons:

1. I installed asciidoctor via brew
2. In my dotfiles repo, I have a brew file with a list of items, but I do not have or use a gem file, so I would need to add it to my config just for the 1 item

[pepijnve]

Maybe something like https://github.com/sportngin/brew-gem could help there?

[eddiejaoude]

Oh nice, thank you 👍

The problem here is that AsciiDoctor on Homebrew comes with a starter script which explicitly specifies a GEM_HOME:

$ less /usr/local/bin/asciidoctor
#!/bin/bash
GEM_HOME="/usr/local/Cellar/asciidoctor/2.0.15/libexec" exec "/usr/local/Cellar/asciidoctor/2.0.15/libexec/bin/asciidoctor"  "$@"

If you need the asciidoctor-diagram plugin, you need to install that to the version specific GEM_HOME directory. And you need to do that with any update of asciidoctor. I do have a cron Job on my MacBook which performs a nightly update of all formulas. Therefor it would be great if there was a asciidoctor-diagram formula which would then update the diagram feature as well.

Checking in: has there been any further thoughts, movement, motivation for this?

@johnnyutahh nothing from my side and no plans either. Pull requests, If necessary, are welcome of course.
