Problem Every time I put my cursor in code with an error, or even while i’m typing something that is as yet unfinished, I have a new buffer pop up “Flycheck Error Messages”, which then disappears again when I have finished typing. I can’t find a relevant setting. How do I stop this disruption, maybe only having error messages in the modeline? Answer The following variable controls whether the new buffers occupy a new window or, as I desired, can be just in the minibuffer.

For years my workflow has centered in org-agenda and I would go from one clocked item to the next. For instance, I would be clocked into my “Emails” task, which never closes, and then eventually move down in the agenda to “Task B”. Then I hit C-x TAB to clock in. It correctly queries for a comment on the task I’m leaving but no longer clocks me in to the new task as I’d asked.

** This question was posted to the emacs stackexchange. 1 Clojure files should open in Clojure-mode. I also have Clojure files that contain color info and are used to generate my styles; they live under a /styles path. For these files, I want them to have both clojure-mode (a major mode) and rainbow-mode (a minor mode). I can implement this on a file-by-file basis be starting such files with a line like this:

I’ve made the switch to w3m from eww, which has been great overall since the eww thread-blocking was insufferable. However, one of the biggest benefits of eww was the ability to engage a readability mode that cut all but the content of the page, which is also a feature I use a lot on Firefox on my phone. A previous answer from 20201 did something like this but was referencing elfeed, which has nothing to do with my use case, and used a bootstrap Python script.

I was trying to make sure that hl-line mode (to highlight a line) is not on in my dired buffers without changing its presence anywhere else, since it messes up display of my diredfl permission faces. Unfortunately, the following didn’t work, probably because “setting” isn’t the same thing as calling the variable. What was the best way to selectively disable hl-line-mode? There were many good answers on Reddit1. (add-hook 'dired-mode-hook (lambda () (setq-local global-hl-line-mode nil hl-line-mode nil) ;; I wasn't sure on the relationship between ;; these two, or even which one was being used )) Learning along the way: global- is unrelated to hl-line-mode It turns out that global-hl-line does not share anything in common with hl-line-mode other than the end result, so altering one does not alter the other.

My userChrome.css doesn’t seem to be doing what it did previously, and the text in my URL-bar is far too small. Here’s what fixed it in my userChrome.css previously: #urlbar {-moz-appearance: none !important; font-family: Tahoma Bold !important; color: Black !important; font-size: 16pt !important; } but it doesn’t seem to be doing anything now; change the font-size and restarting Firefox doesn’t seem to make any difference. Why is it behaving differently now?

BBDB1 is one of those libraries that has been around for so long it would be highly irregular if we weren’t talking about Emacs. The size and age of the thing is what originally scared me away from it in favor of org-contacts2, which had the advantage of being orgmode but was deprecated a long time ago. With BBDB you don’t usually view the elisp database that lies beneath, instead using its robust interface to interact.

Shared on the Emacs Tip & Tricks thread 1. Anzu is great for previewing your query-replace as you go; just remember not to attempt it on HUGE files as the preview (or at least, result counting) gets problematic. Also remember that if you are doing a regexp replace that has side-effects (e.g. incrementing a counter), the preview itself will also do all those side effects before you run the actual replace.

For reasons of internal review but also for the benefit of the community, at work I’ve started recording and making public some of our work meetings, where we build web applications using a full-stack Clojure setup derived (years ago) from Luminus. Several of our team members are brand new to Clojure, so we deal with lots of basics. Questions are welcome! https://www.youtube.com/playlist?list=PLRoUFLqvFD3MRYXTnXQyl-z_svY2gDhFi

Image above NOT a title for Burrough’s 1912 story “A Princess of Mars” 1 This is an essay inspired by Greenberg’s 1996 “Mother of All Emacs papers"2. We learn in that paper that Emacs was born of a necessity for a text tool that had to solve several problems: Hardware (memory space) limitations Costly, lengthy compilation times for other programming languages Steep learning curve compared to arcane character-editing tools, which were painfully close to the assembler and showed it It succeeded in all of these, and after we look at how it succeeded we’ll be ready to think about its viability in an age where the problems have changed completely.
