A long time ago I wrote about some debugging capabilities of Emacs Lisp. The feature mentioned in the last of these posts, debug-on-variable-change, allows to invoke the debugger whenever some Elisp code changes the value of a variable (with a few minor limitations). What I didn’t mention then is that you can actually do things other than start the Emacs debugger when a variable’s value changes.

(For some reason I can’t even remember now, I don’t use the archiving feature of Org.) It occurred to me that having Emacs change the todo state automatically would be very convenient.

I didn’t mention one of the simplest ideas I had, partly because it didn’t work, and partly because a variant of it did work, but was quite involved. So, here is my initial idea and its working version.

As some of you might know, I even wrote a booklet about personal accounting, using Ledger in examples. One of the nice things about Ledger is that it comes with an Emacs mode to edit its files (which is not a surprise, given that it is written by John Wiegley himself). That is not to say, though, that it suits my needs perfectly.
