• 08:38 UTC (new) (history) 2018-11-19 Font-locking diff blocks in Org-mode . . . . Marcin Borkowski – I sometimes miss a feature in Emacs where I could make a diff of two files (using Emacs built-in dired-diff command, bound to = in Dired, or abo-abo’s diff trick, which I have bound to e in Dired), but have the diff persist (as in, save it to a file). Technically, I can do this, of course, by just calling write-file and saving it to a file (preferably with a .diff extension so that it will open in Diff mode automatically), but sometimes I prefer to save things in my Org-mode file, along with my notes related to the project I’m working on. It turns out that Org-mode has me covered, although there is one minor caveat here.

Marcin Borkowski – Today we [[http://mbork.pl/2017-09-25_The_Unconquered|again]] [[http://mbork.pl/2018-02-05_The_death_camps_in_Poland_issue|depart]] from the usual topics of my blog. We have a very important day today in Poland – [[https://www.youtube.com/watch?v=RnbULDJAWeI|one hundred years ago my country gained independence]] after more than a hundred years of political nonexistence.

• 08:54 UTC (new) (history) 2018-11-03 A few remarks about defining minor modes . . . . Marcin Borkowski – Today’s post is extremely technical and niche, but I just wanted to share an interesting story I had a few days ago.

• 14:46 UTC (new) (history) 2018-10-27 Launching terminal in current directory . . . . Marcin Borkowski – I am a bit ashamed that I do not always use Eshell – I sometimes rely on a “proper” bash in a terminal. (One possible reason is when I ant to run something that does not play too well with Eshell, like top or watch. I know it is possible to do that in Eshell, using eshell-visual-commands, but it seems I’m too lazy (or still too much accustomed to my usual terminal) to change that. Anyway, it is feasible to want to run a terminal (or any other program) in the current directory from Emacs. It turns out that it is easy to do using async-shell-command.

• 11:48 UTC (new) (history) 2018-10-22 Running visual commands in Eshell . . . . Marcin Borkowski – It is a known thing that running commands that control the terminal like top in Eshell is problematic – Eshell plays well with commands that take stdin in and put stdout out, but any control codes are just displayed verbatim. Happily, there is a way around it.

• 17:59 UTC (new) (history) 2018-10-14 Magit and C-u i . . . . Marcin Borkowski – Last time I mentioned that I use multiple backup copies of my .env file. One problem with that approach was they they cluttered my Git status (or the magit-status window). I could put the relevant pattern in my .gitignore file, but I didn’t want to bother other programmers in the team with peculiarities of my personal setup.

• 06:24 UTC (new) (history) 2018-10-06 The version-control variable . . . . Marcin Borkowski – As many of us know, Emacs has a habit (annoying for most people, I guess) of making backup copies of files it saves. Happily, it doesn’t kick in in version-controlled files (and most of my files fall into this category nowadays). But there are situations when I actually do want the backup copies.

• 06:59 UTC (new) (history) 2018-09-30 add-dir-local-variable - conclusion . . . . Marcin Borkowski – In the last two posts, I wrote about Emacs directory variables. Last week, the conclusion was that there is no easy way for add-dir-local-variable to use the dotted pair notation in the .dir-locals.el file. Well, I was wrong again.
• 06:57 UTC (diff) (history) Comments on 2018-09-23 add-dir-local-variable and dotted pairs . . . . Marcin Borkowski – Thanks, this is really great!

• 04:50 UTC (new) (history) 2018-09-23 add-dir-local-variable and dotted pairs . . . . Marcin Borkowski – Last time I wrote about directory variables. I mentioned that the eval keyword apparently didn’t work with them. Well, I was very wrong, and my mistake was a popular one. Since it is easy to fall for it, I decided to warn here about the pitfall.
• 04:23 UTC (diff) (history) Comments on 2018-09-17 Emacs directory variables . . . . Marcin Borkowski – Thanks, this is really interesting, although seems a low-level hack.
• 04:19 UTC (diff) (history) Comments on 2018-08-13 A tip on git stash . . . . Marcin Borkowski – Wow, I had no idea! Thanks so much!!!

• 08:18 UTC (new) (history) 2018-09-17 Emacs directory variables . . . . Marcin Borkowski – Many people know and use Emacs file variables. I think less people know about a similar concept of directory variables.

• 07:56 UTC (new) (history) 2018-09-10 Persisting Emacs variables . . . . Marcin Borkowski – Some time ago I coded a certain Elisp tool (for internal use at Wiadomości Matematyczne) and I needed to preserve the value of some variable between Emacs sessions. I asked how to do this on the Emacs mailing list, and I received a whole lot of very interesting and worthwhile responses.

• 17:09 UTC (new) (history) 2018-09-03 Emacs obsolete commands . . . . Marcin Borkowski – In one of my previous posts I mentioned that the Info-edit command is obsolete. You might be wondering what that means exactly. (I was, for sure.) Well, here’s the story.

• 19:34 UTC (new) (history) 2018-08-27 Whitespace in Emacs regexen . . . . Marcin Borkowski – Some time ago I wanted to search for a sequence of two words in a buffer. Normally I’d search for lorem<space>ipsum, but what if there is a newline between them? Or a non-breaking space? Or a tab?
