Reproducing Org mode configuration

Context

Recently I was trying to reproduce a bug with citeproc.el and org-mode in emacs.

I thought I could use package-vc-install to install a set of upstream emacs packages at fixed versions, and thereby let citeproc upstream test in the same environment as I have.

It turns out that getting emacs to load the non-builtin version of org via package-vc-install did not work because

  • org-mode needs to run make after cloning
  • once package.el was initialized, I always seemed to end up with the built in org-mode (yeah, I realize that isn't an explanation).

Recipe part 1: get org

Here you can replace 9.8.7 with any other tagged release

  EMACSHOME=$(mktemp -d)
  git clone https://git.sr.ht/~bzg/org-mode ${EMACSHOME}/org
  git -C ${EMACSHOME}/org reset --hard release_9.8.7 
  make -C ${EMACSHOME}/org autoloads
  emacs -Q --batch -L ${EMACSHOME}/org/lisp --eval "(progn (require 'org) (message (org-version)))"

This should print 9.8.7, not the version of built in org-mode.

Recipe part 2: add-on packages

Now to test some add-on packages, run

    emacs -Q --init-directory ${EMACSHOME} -L ${EMACSHOME}/org/lisp

  (progn
    (require 'org)
    (package-initialize)
    (package-vc-install "https://github.com/emacs-straight/queue")
    (package-vc-install "https://github.com/joostkremers/parsebib" "6.7")
    (package-vc-install "https://github.com/rejeep/f.el" "0.21.0")
    (package-vc-install "https://github.com/magnars/s.el" "1.13.0")
    (package-vc-install "https://github.com/akicho8/string-inflection" "1.0.16")
    (package-vc-install "https://github.com/andras-simonyi/citeproc-el" "0.9.5"))

You can then run your tests in that emacs right away, or restart the environment with

  emacs -Q --init-directory ${EMACSHOME} -L ${EMACSHOME}/org/lisp

Tangling multiple files

I have lately been using org-mode literate programming to generate example code and beamer slides from the same source. I hit a wall trying to re-use functions in multiple files, so I came up with the following hack. Thanks 'ngz' on #emacs and Charles Berry on the org-mode list for suggestions and discussion.

(defun db-extract-tangle-includes ()
  (goto-char (point-min))
  (let ((case-fold-search t)
        (retval nil))
    (while (re-search-forward "^#[+]TANGLE_INCLUDE:" nil t)
      (let ((element (org-element-at-point)))
        (when (eq (org-element-type element) 'keyword)
          (push (org-element-property :value element) retval))))
    retval))

(defun db-ob-tangle-hook ()
  (let ((includes (db-extract-tangle-includes)))
    (mapc #'org-babel-lob-ingest includes)))

(add-hook 'org-babel-pre-tangle-hook #'db-ob-tangle-hook t)

Use involves something like the following in your org-file.

#+SETUPFILE: presentation-settings.org
#+SETUPFILE: tangle-settings.org
#+TANGLE_INCLUDE: lecture21.org
#+TITLE: GC V: Mark & Sweep with free list

For batch export with make, I do something like [[!format Error: unsupported page format make]]

Using Org Mode as a time tracker

I have been meaning to fix this up for a long time, but so far real work keeps getting in the way. The idea is that C-C t brings you to this week's time tracker buffer, and then you use (C-c C-x C-i/C-c C-x C-o) to start and stop timers.

The only even slightly clever is stopping the timer and saving on quitting emacs, which I borrowed from the someone on the net.

  • Updated dependence on mhc removed.
  • Updated 2009/01/05 Fixed week-of-year calculation

The main guts of the hack are here.

The result might look like the this (works better in emacs org-mode. C-c C-x C-d for a summary)
