Tip: have vim handle SlackBuild .info files properly

dugan · 04-21-2018, 08:22 PM

Put the following in .vimrc:

Code:

autocmd BufEnter,BufNew *.info call CheckSlackBuildInfo()
function CheckSlackBuildInfo()
    if filereadable(expand('%:p:r'). '.SlackBuild')
        setlocal filetype=sh
    endif
endfunction

Then, if you open a file whose extension is .info and there's a corresponding SlackBuild in the same directory, vim will treat the .info file as shell script.

It would be nice to have a sub-forum for things like this.

This one?

I thought this tip was slackware-specific enough to belong here.

I was thinking more Slackware centric.

I mean, how many distros ship with vim as standard software?
And how many use .info files for their installers/packages?
(Honest questions, I don't know)

A lot of tips could be considered "Slackware specific" especially ones that get thrown around here, just because Pat (and us) do things more as the devs intend. So yea, they could be considered "Linux" success stories, but how much can be applied to another distro without modification?

Anyways, it was just a thought.

Nice idea, here's a version for Emacs people (goes in ~/.emacs):

Code:

;; enable syntax highlighting for SlackBuild .info files
(add-to-list 'auto-mode-alist '("\\.info\\'" . check-for-slackbuild))
(defun check-for-slackbuild ()
  "Check for a SlackBuild in the default directory of the current buffer, and set the major mode accordingly."
  (if (directory-files default-directory nil "\\.SlackBuild\\'")
      ;; set unix config mode if there is also a *.SlackBuild file
      (conf-unix-mode)
    ;; otherwise just text mode
    (text-mode)))
;; also update magic-mode-alist to test for *.info files by regexp
(add-to-list
 'magic-mode-alist
 '("PRGNAM=\".*\"" . conf-unix-mode))

I added an extra bit to test for a SlackBuild .info file even if the SlackBuild itself is missing (assuming the first line is PRGNAM="some text").

I suppose the LQ wiki might be a good place.
