• 20:21 UTC (new) (history) 2024-12-25 Merry Christmas 2024 . . . . mbork – What eye has not seen, and ear has not heard, and what has not entered the human heart, what God has prepared for those who love him. Let us rejoice, because Christ is born today to save us from the devil and the consequences of our own evil deeds! And let us rejoice because the Holy Spirit guides us every day so that we may do good, too! And according to the little tradition of mine, I will of course say a decade of Rosary for all of you, my dear readers. Happy Christmas!

• 15:48 UTC (new) (history) 2024-12-23 Watching variable changes . . . . mbork – Today I have a short Elisp trick, probably slightly more interesting than useful, but still. 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.

• 07:41 UTC (new) (history) 2024-12-01 Automatically inserting Ledger transactions . . . . mbork – I wrote a few times that I use and like Ledger a lot. 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.
