It seems homebrew has removed all the options (incl. --with-cocoa) for brew install emacs. Now it recommends to use brew cask install emacs to get a built binary from https://emacsformacosx.com/. However, it is not clear to me which options are used to build the binary. The ones I care about are:

--with-modules --with-cocoa --with-gnutls --with-librsvg

Is there still a way to use homebrew to build the latest emacs but with the options above? If not possible, then how do we build emacs from source on OS X (10.12+) with those options

Any Emacs can show you how it was configured at build-time. Inspect the value of system-configuration-options with Meta+h v. A recent Emacs from https://emacsformacosx.com/ shows:

system-configuration-options is a variable defined in ‘C source code’.
Its value is
"--with-ns '--enable-locallisppath=/Library/Application Support/Emacs/${version}/site-lisp:/Library/Application Support/Emacs/site-lisp' --with-modules"

Documentation:
String containing the configuration options Emacs was built with.

If that doesn't satisfy you, you can either do:

$ brew edit emacs
# make the changes you want
$ brew install -s emacs

or install emacs from its source at https://ftp.gnu.org/gnu/emacs/emacs-26.1.tar.gz

You may install emacs-plus from this:

From that link:

Note that by default emacs-plus builds the Cocoa version of Emacs with gnutls, imagemagick, librsvg and dynamic modules support by default.
