Please add a --with-c-source flag

I would like to install this with the C source attached, so that when I look for references to variables or functions, the C source is in a predictable location.

Looking at the installed content, I can't find any sign of it; if it's in a different location, I'm also happy to locate it from there.

Thanks for the formula in general, though!

Hey

I would like to install this with the C source attached, so that when I look for references to variables or functions, the C source is in a predictable location.

Both emacs-plus@29 and emacs-plus@30 are always built from sources, and you can find the source under $HOME/Library/Caches/Homebrew/emacs-plus@29--git/ or $HOME/Library/Caches/Homebrew/emacs-plus@30--git/ respectively. So until released there is no need to provide any extra options here.

Released versions (e.g. emacs-plus@28) have --HEAD option which installs from git source. And that gives the same effect as with unreleased versions. Though, a slightly different version.

In theory, we might provide an extra option to build released version from git source instead of provided tar files. The source will be located in the very same $HOME/Library/Caches/Homebrew/emacs-plus@VERSION--git. Though I would love to avoid that and provide either --HEAD or released version.

That being said, is $HOME/Library/Caches/Homebrew/emacs-plus@VERSION--git a "predictable location" for you?

P.S. Just for completeness. brew provides an option to build from source (--build-from-source or -s for short), which builds from source even if bottle is available. I do not provide bottles anymore.
