@daviwil wow this is interesting, let's explore Tree Sitter more. I think it's a game changer for manipulating text in emacs, since we can use Tree sitter query to find some text. (And some say, it's fast)
The value of #Emacs is not in the packages that are available (Gnus, org-mode, Magit, etc.). It is the fact that these packages live in the same application, manipulate text the same way, and can interact with each other to do exactly what you want them to do.
@galdor one part of this that always blows my mind is that buffers are a primitive data type yet the whole point of Emacs is to display buffers. Everything in Emacs is just changing the display of, and operating on, buffers.
To say it a different way, you can't construct a buffer from more basic Elisp elements. A buffer is the most basic data type, on par with a symbol or a literal. Yet it's also the main way users and developers interact with each other.
I don't know of another project where the developers and the users are all using the same concept as a building block. It would be like if matlab was written entirely using arrays.
@galdor What is amazing to me is how extensible both #Emacs and #Vim are while using completely differently approaches.
And how little modern editors have learned from them. I don't want to poopoo on modern editors as some are really good and cool. But very few have been build on this fundamental philosophy of extensibility.
Please help collecting statistics to optimize Emacs GC defaults
Many of us know that Emacs defaults for garbage collection are rather ancient and often cause singificant slowdowns. However, it is hard to know which alternative defaults will be better.
If you've got questions about Emacs, Guix, Guile, or other related topics and want a friendly place to ask them, come check out the new System Crafters Forum!
@sqrtminusone@publicvoit@ericsfraga it seems like this may be the admin API, not sure if a user can use the same endpoints. There is a way to get a user API key though but I haven't looked at whether there is a different set of endpoints for that purpose
@sqrtminusone@daviwil@ericsfraga I'd prefer a Discourse to NNTP gateway instead. Then you'd be able to use it with maybe hundreds of clients not just Emacs. 😉
I always told people that #texlatex is best written/edited in #emacs but didn't have a better argument for it than how well everything integrates. #AUCTeX, pdf-tools, #magit, etc. make it a seamless experience. I had a little bit of YASnippets going as well which made life wonderful.
That already brought things to the state of Gilles Castel's 2019 latex lecture notes in #vim article (which I believe is famous, at least in these circles). But yesterday I found a blog post by @karthink about how to get that and more in Emacs.
The very first demo (40 seconds) shows how to get an equation in latex that I am sure would take me over a minute to write by hand (and it would look ugly in comparison). Then I looked at the second video (45 seconds) and realized that somehow org table style editing can be used for things like matrices and arrays and what not.
Just like that, less than 2 minutes has me committed to getting all that functionality in my Emacs config. Of course, this being emacs, I can tailor it all precisely to my comfort and I'm willing to spend however long is needed to get it to that stage.
I'm not new to the Fediverse (much of my posting was done on the SDF Mastodon instance at https://mastodon.sdf.org/@ephzero), but I see it's #followfriday , so let's throw some tags out here in no particular order:
This is a two-for-one, these are two tips that I can't believe I never learned about it until now.
What is an easy way to see the value of a variable, or see the result returned from a function call?
You might know about the M-: (Alt-Colon) command, which lets you run any Lisp code, the result is printed into the *Messages* buffer. But... if you use the prefix command C-u (Control-U) and then press M-: (Alt-Colon), the result returned by the Lisp code is printed into the current buffer after the cursor.
Even better, however is using the (pp) ("Pretty-Printing") function. This also outputs to *Messages* by default, but it takes 2 arguments, the second of which can be a buffer. Try this code:
(pp (buffer-local-variables) (currrent-buffer))
The result returned by (buffer-local-variables), which is a list of all buffer-local variables and their values, is pretty-printed right after the cursor.
If you want to be notified of scheduled and deadlined tasks in Org mode, there is no better way than with org-yaap. It has zero dependencies other than Emacs 27.1 and it works great on Android with termux.
I've been using it for two years without issue. The documentation and options are superbly setup to fit most uses of Org:
"""
By default, you will be notified for all scheduled headings (org-yaap-include-scheduled') and headings with a deadline (org-yaap-include-deadline') within your agenda files. If a heading only includes the date, you will be notified at 9am on the day of the heading (org-yaap-daily-alert'). If you don't mark a heading as done, you will be repeatedly notified every 30 minutes after the heading was due (org-yaap-overdue-alerts').
"""
@grinn Cool! Have you written anything about how you use Emacs with Termux? I find that it works surprisingly well but I haven't done much to integrate it better with the phone experience
The best time to learn #emacs and #orgmode is ten years ago. The second best time is today. I use #orgmode as my calendar and organiser, and each year I discover something more awesome in it. I didn't realise how good the exporter is and how well formed the HTML is, so now I'll keep my notes on astronomy literature in a new org file. Future proofing through flat text files FTW.
I’d like to welcome the M-x Research group on Emacs.ch: @Mx_Research :blobfoxemacspeek:
M-x Research is a community of Researchers and Research Software Engineers. They hold virtual meetings bi-weekly to discuss and share #Emacs experiences, tips, tricks and tools useful for researchers and research software engineers. Newcomers and veterans are all welcome.
Fabrice Niessen, Developer and evangelist for Org mode and creator of the org-html-themes, is offering hands-on Emacs training in a three day course in Rotterdam, Valencia and Paris this spring.
Wow, I can't believe I'm only just learning about the org-pretty-entities variable in #Emacs#orgmode. Setting it to t automatically transforms a lot of LaTeX fragments into unicode symbols in the buffer.
I've been using the $ delimiter around very small fragments (e.g. $\sigma^2$) and then using org-latex-preview to show it in the buffer. Much slower and clunkier obviously, I wish I had known about this a year or two ago! 🤦♂️
I would like to give a shout out to all the excellent people on emacs.ch. You are not only passionate about Emacs and Lisp, but also friendly, fun and always willing to help out.
While the LSP protocol is useful for completion or access to symbol definitions, some of its features are less appealing. In #Emacs, you can instruct Eglot to ignore any feature you dislike.
E.g. (setq eglot-ignored-server-capabilities '(:inlayHintProvider)) to remove annoying hints mixed with the code in c-mode with clangd.
Guy from the future appears in your coffee shop. Turns out it's @lisperati writing a game in #emacs on his Yoga Book i9 using a 7 year old 40% keyboard using angry fruit salad mode. You're just 5 years behind the curve man.
#emacs and #haskell people, I have an Emacs hoogle frontend on #ELPA called consult-hoogle. It uses consult to present search results from hoogle. I have added another mode in which results are presented in a buffer. As a result it can also display search results from https://hoogle.haskell.org/ using the JSON API.
To anyone in and around Erlangen/Nueremberg, I am organising a german introduction to Emacs next week (10.5.) at my university. My intention is to give a high-level, value-driven overview instead of wasting time on accidental and superficial features such as Magit, Org-Mode, SLIME, etc. (there are plenty of those already).
The rootwork v0.2 blog posted about the author's journey through text editors, from classics such as vi(m) and Emacs to tools I've never heard of. They explain what they use the editors for and why.
