Subject: [bug#55420] [PATCH 0/2] Add a function to parse emacs elisp's package header
Date: Sat, 14 May 2022 23:00:17 +0000 [thread overview]
Message-ID: <20220514230017.27372-1-plattfot@posteo.net> (raw)
When writing a guix.scm file for an emacs packages, I wanted a way to fetch
the version I specify in the header of the elisp file. I found that I could do
that with the lisp-mnt library in emacs. Unfortunately none of the emacs
utility functions in guix/build/emacs-utils.scm return the output of an
elisp expression.
With these two patches I aim to add that functionality.
I spilt it in two functions:
emacs-batch-script: Run an arbitrary elisp expression and return the output as
a string.
emacs-header-parse: Given a header section and a file it will return the value
of that section.
For example (emacs-header-parse "version" "path/to/an/elisp/package.el")
Reason for the spilt is that people might want to run other elisp snippets.
Fredrik Salomonsson (2):
guix: emacs-utils: Add emacs-batch-script.
guix: emacs-utils: Add emacs-header-parse.
