Use evm for manage versions installe with brew emacs-head

[anquegi]

I use OSX at work, and I use homebrew to manage my packes exist one emacs package emacs-head It works pretty weel for intalling emacs on OSX an I can install different emacs.

It is a ruby receipe, and get emacs installed in differente folders:

~ via ⬢ v12.4.0
❯ ls /usr/local/Cellar/emacs
emacs/          emacs-head@27/  emacs-head@28/

And then symlink it to /usr/local/bin to use. Can I use this installed emacs with evm to select versions in my shells?

Because in the readme I only see that I need to write a receipe. can I Use the receipes in the brew repo emacs-head. This are using with cocoa that I saw here is not supported

You can only select versions using EVM that has a recipe. You could use the Git snapshot versions instead of emacs-head perhaps?

Thanks for answering, Well, I allready have several versions of emacs installed, so I would know if I can use evm to point this allready installed versions of emacs using homebrew and emacs-head which ejecutables are here:

And where installed with a lot of modules enabled i.e.:

~ via ⬢ v12.4.0
❯ brew install emacs-head --HEAD --with-cocoa --with-dbus --with-mailutils --with-pdumper --with-xwidgets --with-crash-debug --with-ctags --with-imagemagick

~ via ⬢ v12.4.0
❯ brew install emacs-head@28 --with-cocoa --with-dbus --with-mailutils --with-pdumper --with-xwidgets --with-crash-debug --with-ctags --with-imagemagick --with-native-comp --with-native-full-aot

. Because this distribution has --cocoa and other options active that could be used and maybe I build install other distributions for OSX.

I see that you can list the binary path to emacs executable. so maybe is some configuration file that I can edit and point to theese executables

So I also asked if another option could be write my custom receipe for evm following this receipes from homebrew

It was such a long time ago I wrote this so I don't remember, but take a look at https://github.com/rejeep/evm/blob/master/lib/evm/package.rb. It seems there is a config Evm.config[:path], maybe that could work? Otherwise, I don't think it should be difficult to update that file to support it.
