• 04:56 UTC (new) (history) 2019-06-24 org-agenda-todo-ignore-timestamp vs org-agenda-todo-ignore-with-date . . . . Marcin Borkowski – Org Agenda is a legendary feature. One of its selling points is customizability (as is usual in Emacs in general). This, however, comes at a price: agenda generating is slow, even though it is reportedly heavily optimized. (At the worst moment, my agenda took about half a minute to generate. A naive benchmark convinced me that the reason was a rather large Org file, weighing almost a megabyte and containing several thousand headlines (a.k.a. capture.org). No surprise, and a good candidate for optimizing (most of its entries do not really need to be even considered for agenda, so those which do can be moved to another file, and this one can be excluded from agenda generation). But today, I’d like to talk about something else – two of the many options governing agenda generation, namely org-agenda-todo-ignore-with-date and org-agenda-todo-ignore-timestamp.

• 18:21 UTC (new) (history) 2019-06-15 Debugging Node.js programs in a Vagrant virtual machine . . . . Marcin Borkowski – One of the very nice things in a programmer’s toolbox is a debugger. Coming from Emacs, I am accustommed to Edebug, which allows to step through the code, install breakpoints (conditional ones as well as unconditional ones), watch variables etc. Programming in JavaScript is (or at least should be) no different. Indeed, both Firefox and Chromium have a debugger in their DevTools (although Chromium’s one seems a tad more confusing). This is all good when I’m debugging front-end code, but I often work on some backend code in Node.js. Fortunately, it can be debugged, too.

• 16:09 UTC (new) (history) 2019-06-09 Defining custom TikZ fill patterns . . . . Marcin Borkowski – Some time ago I had a need to define my own filling pattern in TikZ. It turned out to be quite simple, although I had to learn a few things. While the manual (as usual) does a pretty good job at teaching that, I felt that the explanation was a bit too short in one place, and hence this blog post.

• 18:50 UTC (new) (history) 2019-06-03 Undoing without redoing . . . . Marcin Borkowski – Emacs has a somewhat atypical undo feature – if you undo some changes (possibly more than once), and then break the sequence of undo commands (for example, by moving the point), any subsequent undo will, well, undo the previous undo – in other words, Emacs’ undo doubles as redo.
• 18:49 UTC (diff) (history) Comments on 2019-05-27 Programmatically checking for uncommitted changes . . . . Marcin Borkowski – Wow, thanks for all these comments! As for the if-then-else stuff, I obviously have other things inside - {{{exit 0}}} and {{{exit 1}}} were just . . .

• 06:04 UTC (new) (history) 2019-05-27 Programmatically checking for uncommitted changes . . . . Marcin Borkowski – One problem that I encounter over and over again is checking if a Git repository is “clean”, i.e., if it doesn’t contain any uncommitted changes. This post serves as an easy way to remind myself how to accomplish that.
