Popular libraries like Lodash or Ramda have a function for that (in both cases, it’s called range), but how to do that concisely in vanilla JS? In case you’re wondering, both Lodash and Ramda use a while loop for this task; can we do better? (In this case “better” does not necessarily mean “faster”, but “shorter”, and – let’s be honest — “in a more clever/hackish/crazy way”.) It turns out that the answer is yes.

• 16:39 UTC (new) (history) 2026-03-02 Lispy and Iedit . . . . mbork – A bit over a decade ago (!) I wrote about Iedit. It’s a very cool package, a bit similar to multiple cursors, very convenient for changing variable names (especially that it has a great feature where the change is restricted to the current function). I am also a Lispy user. Lispy requires Iedit (and has a binding for it different from the default one – M-i – while Iedit’s default I’m used to is C-;). The problem is, when I added Lispy to my Emacs, it disabled the default C-; (and only installed M-i in Elisp buffers). Now, I admit that M-i may be a better (or at least not worse) keybinding for Iedit than C-;. It’s default binding is tab-to-tab-stop, which is one of those useless commands Emacs has had probably for decades. Personally, I’m accustomed to C-;, so I wanted Lispy not to interfere with Iedit setting that keybinding.

• 17:07 UTC (new) (history) 2026-02-21 Org links’ targets . . . . mbork – When I write blog posts containing several links (usually to Emacs documentation, sometimes to my other posts and sometimes to other websites), one of the things I do is to check if all the links are correct. Usually I just middle-click on every one of them in the browser and see if they lead to the right place. I thought, however, that it would be useful to be able to see where an Org link points to without actually going there.

• 15:03 UTC (new) (history) 2026-02-16 Toy train timetable improvements – buttons . . . . mbork – A few weeks ago I wrote about my toy train timetable clock. I used it with my son a few times since then, and it worked great. However, some things that I imagined would be a good idea turned out to be a bit worse UI-wise.
