However strange it may sound, a few days ago I have a very atypical need. I needed to move some LaTeX code to a JSON file. This meant that all the backslashes had to be doubled, of course – LaTeX code is full of them, and they need to be escaped in JSON. Obviously, query-replace​’ing backslashes with double backslashes is easy, and query-replace only operates on the region when it is active, but I wanted to make sure I didn’t replace them twice by accidentally marking too much. So – partly as an exercise, I guess – I decided to write a command to replace every backslash in the region by two backslashes, but only if it was a single one.

• 07:18 UTC (new) (history) 2022-11-07 Counting working days again . . . . mbork – Some time ago I wrote about counting business days in Emacs. I mentioned that I’m going to revisit that topic in the future. Well, the future is now! Recall that the need I had was to know how many business days there are in any given month.

• 10:16 UTC (new) (history) 2022-10-29 A bash helper for prefixed scripts . . . . mbork – Let’s say we have some project we are working on. The project involves a number of shell scripts for various tasks, like versioning, building, testing, deploying etc. It is useful to have these scripts in your $PATH while working on that project. There are several ways to do that. One way is to add the directory containing them to $PATH, but only for the time we’re working on the project. Another is to use things like npm run and the scripts property of package.json (and I’m fairly sure many other languages feature similar facilities). Recently, I found yet another one, which is pretty useful and extremely cool at the same time. I prefixed all the scripts with the project’s (abbreviated) name, say dw-​. So, assume I have scripts like dw-version.sh, dw-build.sh, dw-test.sh etc. Now I can permanently add the directory containing them to my $PATH, since I (kind of) namespaced them and they won’t get mixed with any other project’s scripts (nor general use utilities). The only trouble that’s left is that typing dw- each time is a bit tedious. Well, Bash to the rescue.

• 06:18 UTC (new) (history) 2022-10-24 Playing videos from the last position in mpv . . . . mbork – Two weeks ago I wrote about saving timestamps in YouTube links. It turned out that there is a much, much better solution to the problem I was having.
