This package provides notmuch queries in emacs using consult. It offers interactive functions to launch search processes using the notmuch executable and present their results in a completion minibuffer and, after selection of a candidate, single message and tree views.more ...
i've been using Bastian Bechtold's org-static-blog for this blog for more than a year now. Back in the day, i mentioned how well it integrated with my emacs workflow and how its simplicity was a big asset1.more ...
I use Dmitry Gutov's diff-hl to highlight (with fringe marks) modified
hunks in my files under git revision control. The package comes with
diff-hl-next-hunk, that one can use to navigate them. So,
taking a peek at
consult-lines, it was straightforward to put together
a consult function to navigate, with completion and preview (although
i disable the latter) the hunks in the current file:
After my latest adventures writing a small spotify library and learning in the process a bit more about consult, its author, Daniel Mendler, was kind enough to comment on how i had implemented the asynchronous search using consult's API, showing me better ways.more ...
i've found these last days a handful of really useful little emacs packages:more ...
A couple of days ago, i was writing about embark and my first experiment defining a new embarking to play remote video streams. Omar Antolín Camarena, embark's author, has been kind enough to not only read it, but comment on a couple of significant improvements that i think well deserve this follow-up.more ...
Inspired by Prot's musings on completion, i've, ahem, embarked in a reconsideration of my completions setup (as you might have intuited from my recent experiments with the spotify API and consult). As it happens, i'm starting to feel quite at home with a combination of selectrum, prescient and consult, and the ideas to augment what i have with contextual actions using embark seem really natural to me.more ...
I've just published GNU MDK 1.3.0, its 28th release, which finally migrates MDK's graphical user interface to GTK+ 3, to keep up with the, ahem, not-so-modern times and see to it that MDK keeps alive for at least another decade or two.more ...
i've been maintaining xmobar for more than a decade now, and i still use it daily and tweak it almost as often. With almost a hundred contributors besides myself, and many bugs to solve, i am always learning new things. The latest one, that font awesome thing everyone seems so fond of.more ...
i don't dislike emacs' mode line, i just wish (possibly out of a fetish for simplicity and minimalistic user interfaces) sometimes it wasn't there.more ...
For years, i've been using
C-x o and
C-c <n> to move to other
windows, but with ace window i am substituting all of them with
Problem is, muscle memory interferes and i find myself clumsily moving
around (and often lost) with the former ones. Or i did, before i
followed an advice from Stefan Monnier in emacs-devel: unbind those
keys you want to forget, and you'll get an error when you relapse.
As i've mentioned in a previous post, i organise my emacs sessions in
workspaces, a.k.a. frames, a.k.a. a thematic tiling of windows. It is
therefore important to have quick ways of jumping from a window to
another. Until very recently, i used a home-cooked collection of
C-c 2 …
C-c n) that would move my point to the nth
window in the workspace (i trained myself to count them quick enough,
i suppose), and used that together with the stock
C-x o and with
(other-window -1), for something similar to "previous
window", to move around. But i've discovered a better way.
i typically organize my computing sessions around workspaces, which in emacs are simply glorified default window configurations, sometimes in a one-to-one relationship with emacs frames1. That's specially natural if you use exwm, where there's a concept of workspace essentially equivalent to emacs frame. So here too i'll have a "coding" workspace with programming buffers, a "browsing" one inhabited by emacs-w3m buffers in a two-pane layout, an "X" for the few non-emacs applications i use, and one devoted to "email/calendar/agenda", where Gnus plays a central role.more ...
i've been learning a tiny bit about web security at mozilla's Web Security pages, and used their Mozilla Observatory to analyize this site and make it a bit safer. it was just a matter of adding a handful of headers to the webserver configuration, to wit:
Emacs being, essentially, my operating system and window manager, i've had since i remember a set of keybinding maps grouped by functionality (sleep and related operations, media player control, network access, and so on), whereby every group of commands starts with the same prefix. E.g., all my commands controlling media have a keybinding starting with `C-c m`. Nothing earthshaking, and pretty common. Recently, the transient library has made my life easier in this department.more ...
Posted to comp.lang.scheme on January 17, 1996, for Scheme's twentieth birthday.
I got started with literate programming many years ago, out of admiration for almost everything else i knew done by Donal Knuth, and tried my hand at it in some toyish projects in OCaml and Scheme. So it wasn't without lack of enthusiasm that i plunged into the literate world.more ...
Unlike most chat systems in common use, Signal lacks a decent emacs client. All i could find was signal-msg, which is able only to send messages and has a readme that explicitly warns that its is not a chat application. Skimming over signal-msg's code i learnt about signal-cli, a java-based daemon that knows how to send and receive signal messages, and how to link to a nearby phone, or register new users. And playing with it i saw that it can output its activities formatted as JSON, and that offers (when run in daemon mode) a DBUS service that can be used to send messages.more ...
I like simple things. As simple as possible, but not simpler: they should live well in my little emacs universe. Bastian Bechtold's org-static-blog, a static site generator using org-mode, is the latest star in that virtual world.more ...
I am having a great time reading Smullyan's Gödel's Incompleteness Theorems, a thin volume with the most elegant description of Gödel's and Tarski's work i've read so far. It's also the most succint, and it starts with a very nice and very clear demonstration of indecidability that is the simplest i have ever seen. I like it a lot, and it's short enough for a quick blog post. Here it goes.more ...
Last October Don Stewart gave a very interesting talk at CodeNode on his experience using Haskell at a large scale. And by large, he means millions of lines of code. Although he wasn't allowed to talk about the very specifics of the code, his talk is full of interesting remarks that i found resonate with my experience. They actually convinced me that the next language i should try in production should be OCaml.more ...
