• 19:08 UTC (new) (history) 2021-01-17 Królowa Magnolii I . . . . mbork – No to dzisiaj coś z zupełnie innej beczki. Kilka dni temu skończyłem czytać tom I Królowej Magnolii Marty Marii Dobrzyńskiej. Najkrótsza recenzja, jaką potrafię napisać, ma trzy litery. Wow.

• 15:09 UTC (new) (history) 2021-01-11 Deleting last entry from the kill ring . . . . mbork – The Emacs’ kill ring is a brilliant and extremely useful concept. It has some drawbacks, too, though. Probably the biggest one is that the entries there persist for quite some time. This is, after all, what it’s for – but sometimes you explicitly want some entry to disappear. This is of course the case when you have some password or a similar thing you copy to e.g. config files.

• 20:43 UTC (diff) (history) 2017-01-30 Current Emacs version . . . . mbork – Add a bug warning
• 20:40 UTC (new) (history) 2021-01-04 Current Emacs commit revisited . . . . mbork – Almost four years ago I described a simple command to insert the current Emacs version at point, together with the commit hash taken from the repo. Guess what? A few days ago I found a bug in it.

• 07:58 UTC (new) (history) 2020-12-24 Christmas 2020 . . . . mbork – As usual, the time has come for Christmas wishes to all my readers. Frankly, I have no idea how many of you there are, since I do not track you in any way. But I know that there do exist people who read my blog, and to them I say thank you, and God bless you. (According to my now several-years-long tradition, I will offer a decade of Rosary for you as my Christmas gift!) And please notice this: Jesus, our Lord and Savior, is just so reliable. There may be the epidemic, lockdown, there might even be war, famine or whatever – but He will come to save us. I find it extremely reassuring. Also, this time I’d like to say a bit more than just wishes.

• 19:12 UTC (new) (history) 2020-12-21 Pretty printing json and jsonb columns in PostgreSQL . . . . mbork – And for today I have yet another short PostgreSQL tip. I use a database which has quite a few tables with jsonb – and also json – type fields. (I know, I know. No new json columns, but legacy etc.) Since they often contain quite a few things, pretty printing them is something I tend to do fairly often. Happily, PostgreSQL has a function to do that. Less happily, it only works with jsonb columns, and has a long, awkward name: jsonb_pretty. But it’s no longer a problem for me, since it is easy to create a shorthand.

• 08:41 UTC (new) (history) 2020-12-14 My volume control in AwesomeWM . . . . mbork – Embrace yourselves, since a heresy is coming! I sometimes am outside Emacs (gasp!), and getting to it is a bit uncomfortable.

• 22:02 UTC (new) (history) 2020-12-07 Temporary PostgreSQL tables . . . . mbork – Today I have yet another small PostgreSQL tip. Sometimes you want just to experiment a bit, or maybe move some data around a bit, and then you may have the idea “ok, so I’ll just create this table, do something with it, and then drop it”. Well – you don’t have to drop it.

• 21:43 UTC (new) (history) 2020-11-30 Repeating complex commands . . . . mbork – Today I learned about a fantastic Emacs feature I had no idea about. I knew that the key C-x z is bound to the repeat command, which, well, repeats the last (simple) command – I even use it from time to time. I had no idea, however, that there is another command which can repeat “complex” commands – i.e., ones that use the minibuffer to accept some input.

• 10:52 UTC (new) (history) 2020-11-23 Emacs and the X selection . . . . mbork – One thing I have been reading about lately is the interaction between Emacs and the outside world via the clipboard. Of course, Emacs predates the clipboard by a lot, but it interacts with it pretty nicely. I have a blog post about that in the works, but it’ll need a bit more work, and I’m really busy now (again…), so for today I only have a short tip.

2020-11-16

• 21:34 UTC (new) (history) 2020-11-16 Putting punctuation after closing parens automatically . . . . mbork – I (obviously) use Emacs a lot for programming. While I would be quite happy to code in Lisp all the time, the reality is the reality, and I do mostly JavaScript.

2020-11-09

• 21:20 UTC (new) (history) 2020-11-09 A nice tip about Bash redirection . . . . mbork – Some time ago I had a minor epiphany about Bash redirection. I needed to perform the same command for various files, and each time redirect its results to some file.

• 21:51 UTC (new) (history) 2020-11-01 The situation in Poland . . . . mbork – I really planned to post something else today (I even have written something about Bash redirection – it will just wait one or two more weeks). But the situation in my country, well, escalated quickly, and I think a few sentences of comment are very much in place.

• 07:08 UTC (new) (history) 2020-10-26 Scrolling all windows simultaneously . . . . mbork – One of the things which I need very seldom is simultaneous scrolling in more than one window. And guess what? Emacs has me covered.
