14:10 UTC (new) (history) 2022-09-17 Safe killing with Emacs . . . . mbork – Some time ago Samuel Wales had a very interesting question on the Emacs mailing list. He sometimes kills some portion of text to yank it elsewhere, but gets distracted and forgets about the yanking. This way, the text is lost. He basically wants to make the “kill-yank” cycle atomic so that you never end up in the intermediate step where the information is lost.

18:35 UTC (new) (history) 2022-09-12 Shifting dates or timestamps in PostgreSQL . . . . mbork – For today I only have a short and simple PostgreSQL tip.

From one of the posts there I learned about the x-export-frames function, whose existence is fascinating for me. It basically allows you to make a screenshot of your Emacs frame without ay external program, in one of several formats (including pdf and png). Jean Louis provided some simple code in that post which I reproduce here (with minor changes). The frameshot command takes a picture of your current Emacs frame, puts is in the frameshot-directory directory and moves the point to its line.

15:22 UTC (new) (history) 2022-08-22 The Emacs range package . . . . mbork – Some time ago I discovered something really cool. It turns out Emacs has a package named range which can be used to operate on, well, ranges of integers. The truth is, it supports much more: arbitrary finite sets of integers.
