emacs lisp coding style??

my take. https://www.reddit.com/r/emacs/comments/853ka5/modern_emacs_lisp_development_question/dvw3waw/

am probably gonna be voted down to hell, but here's my way:

The result, should be most simple, lean, readable, maintainable, and fast, code.

the gist of the advices above is, stick to only computer science basis, avoid programer fashions, and do not hack.

if you run into a problem, such as elisp seriously lacking string function, lacking namespace, named parameter, ask emacs dev to add them. (e.g. the limbo state of (require 'subr-x) for string-trim et al.)

galamapain, dealing with typescript, javascript, then have to deal with emacs lisp that runs my code. xah-run-current-file, xah-ts-compile-file, xah-js-mode, xah-ts-mode.

typically, what happens is, i code JavaScript, but actually TypeScript because ES2015 etc, find something not working well, i modify my emacs JavaScript mode, or my TypeScript mode, or xah-fly-keys.

this applies to coding elisp with xah-elisp-mode or clojure with xah-clojure-mode.

Lisp Machine Keyboard, High Cool Factor, Lousy Design Factor

reddit question on lisp machine keyboard and emacs, at https://www.reddit.com/r/emacs/comments/817bp5/since_lisp_keyboards_are_looong_time_gone/

my answer:

the lisp machine keyboard has high cool factor but ergonomically it's really the worst.

[see Lisp Machine Keyboards]

any cheap mechanical keyboard would beat it in terms of ease of use, comfort, macro abilities, typing speed, etc.

if any is really interested in keyboarding efficiency, i recommend keyboardio, smartyao, Microsoft sculpt, kinesis, x-bows, kinessis gaming, or ergodox and many variants.

they feature one or more of:

If you don't touch type and don't plan to learn, and do not have typing load as heavy writer, then you can immediate rule out those split ones, since split isn't useful for non-touch typers that much.

[see Touch-Typing, a Relic of Keyboard Design?]

reddit discussion. Master emacs in 1 year. https://www.reddit.com/r/emacs/comments/7z6pjb/master_emacs_in_one_year/dutha0x/

my comment.

most negative comment here is holier-than-thou syndrome.

people wants to attach mythical quality to emacs.

as tooling goes, mastery of atom editor or code editor and its js language, is far more deep and rewarding, financially or how modern software system works.

if a tool kept you thinking you always don't know something, there's something wrong with the tool or the community.

in fact, vast majority of emacs users for over 10 years, only know how to use the very bare basic features, and know no emacs lisp at all. I know, in part because lots such users told me so, in email or in comment. (most, will not disclose their names in public)

and there are very old users (over 20 years emacs), who even have problems with upgrading emacs, and still stick to how emacs ways of 20 years ago, with their 20 years old habits and config.

most emacs users, they do not read online emacs blogs, or, maybe a couple of times per year. What we see on reddit or other emacs forums, are not typical emacs users.

emacs grep, gnu grep, problems

my reply on a reddit question:


in 1990s to 2000s, first thing on any machine, is to install gnu version of file utils and text utils (which includes grep).

now, i don't bother. These tools, wasn't as important as in the past. e.g. python ruby golang etc, one can write trivially and do much better.

new ones keep cropping up every 5 years. as well as new shells. But i never bothered. For speed, a flash drive is much more important than spinning disk. Most time spent is loading files. (i 'grep' or do find/replace on 5 thousand files every week for past 10 years)

also, gnu text util has unicode bug, but they refuse to consider it as bug. see Linux Shell Util uniq Unicode Bug

so today, i use unix grep only when i need to search a word. If the search involves unicode, or multi-line text, or programing language code with lots slash or backslash, i either use xah-find.el i wrote that stays in pure elisp (avoiding unicode problem, multi-line problem, and toothpick syndrom escape problem), or go to a python script i wrote, for 5x faster speed. (gonna do a golang version soon)

Thanks to FSF/GNU, and 2 Kinds of Thanks

first, i like to say i'm thankful to FSF. No, i was a fanatic of rms, and has been ban'd in mailing lists (around 2002) for pro fsf/gnu/rms harsh opinions. People have called me a rms fanboy.

but, i don't like criticism of fsf/gnu/rms gets voted down for disagreement of opinion than lack of points.

as to appreciation, we, need to thank our mom. She gave birth to us. But we need to thank our dad too, else, we wouldn't exist. Then, we need to thank society, because mom and dad can't survive by themselves. And, we need to thank our firemen, for, he protects us, and soldiers. Thanks to our teachers and philosophers too, sans of which, i haven't clawed your eyeballs out yet.

there are 2 kinds of thanks. One is which they do by themselfs. The previous paragraph, are such. Your mom and dad no really need thanks from you because they'd birthed someone else anyway.

the other thanks, is person do because of you and for you sans necessity. If i give you a buck, or been kind to you, you thank me, a dear thank, because i don't have to. In this regard, the average parents, firemen, soldier, teacher, family, your church, school, company, government, don't qualify. But particular good persons, qualify. I have many people in emacs community am thankful to in this regard, too.

emacs, best simple package source code to learn from?

someone asked on reddit.

my answer https://www.reddit.com/r/emacs/comments/7l98a8/best_simple_package_source_code_to_learn_from/drkrnbs/

well, i run a emacs tutorial on writing major modes. If you haven't seen already, The topics covered are:

How to Write Major Mode

Syntax Table

see Emacs Lisp How to Write Major Mode

if you read the emacs lisp manual, it recommends that the text-mode is a simple mode you can learn from.

For programing modes, i learned things from the builtin css-mode written by the previous emcas leader Stefan Monnier.

but other than that, i didn't learn writing mode much from looking at other modes. I learned mostly from reading elisp manual and writing your own, and looking at source code of arbitrary builtin functions when necessary.

emacs lisp: how to undefine a face

someone asked at https://www.reddit.com/r/emacs/comments/7l42rc/how_do_a_unbind_a_face/

my answer: https://www.reddit.com/r/emacs/comments/7l42rc/how_do_a_unbind_a_face/drjerh6/

detail at

Elisp: How to Define Face

emacs, current problem is, ido-completing-read doesn't take obarray. very annoying. so now, like, i need to rewrite ido-mode

here's the problem. ido-completing-read doesn't take an obarray. (obarry is a special array that hold all elisp symbols) And that's probably why ido doesn't do M-x.

To use ido for M-x, you need to convert obarray to a list of strings. But you don't wannna do this everytime M-x is called. length of obarray is 15k.

Thus, a cache idea is born. So that's probably why smex has cache, probably as after thought. with added feature of sorting most frequently used command. But note, cache adds complexity, cuz now you have the issue of when to regenerate cache.

the emacs completion is truly a mess. The mothership don't change due to org problems, so you have a wild bunch packages trying to improve it, for the past 20 years. Note that, icomplete is from 1993. What really should be done is fix emacs completing-read (it's in C)

hippie-expand, complete-symbol, iswitch (now defunct), icicles, ido, ivy, helm, company, auto-complete, yasnippet, all tries to implement their own completion.

elisp, What's the difference between set and setq

someone asked on reddit. My answer:


but more detailed answer is here Elisp: Lisp Symbol

should a beginner programer learn emacs lisp?

someone asked on reddit.


here's my reply.

if you are new to programing, best is to read Emacs Lisp Intro by Robert J. Chassell

this is part of emacs. Just M-x info and you'll see it. (it's also on FSF website.)

this is for people who never programed before.

however, if you already know a programing language, it is a worst, useless, book. Because, you will have to scan 10 pages to learn 1 simple elisp thing. It'll be explaning what's a variable, function, loop, etc, intermixed with elisp stuff.

for beginner programer, should you learn elisp? it depends. Learn elisp does not hurt at all, nor will it be magic in teaching you something you won't find elsewhere.

The question is really, what do you prioritize.

If you want to customize emacs, yes, learn elisp. It is the only way.

If you are thinking maybe elisp is a stepping stone to get you over other programing or jobs meanwhile you still get value of customizing emacs, then, stop the fantasy right here. You better off to learn python, ruby, golang.

Found a problem with ivy mode. If you run repeat-complex-command, it bloats up your history like this:

ivy redo problem 2017 12 12 92325
ivy redo problem 2017-12-12. Blowing up minibuffer history. The line should be just “(xah-image-autocrop)”

emacs 26 force typing yes/no for deleting dir?

emacs 26 dired deleting directory force user to type full “yes/no”. exceedingly annoying. apparently, it's hardcoded, bypassing yes-or-no-p alias to y-or-n-p

this is hardcoded in dired--yes-no-all-quit-help at dired.el

This is super annoying. Why's this change?

it used to be, the code calls yes-or-no-p, and user can alias it to y-or-n-p, so that typing y or n is enough.

emacs lisp byte code internal

here's a great article.


Chris Wellons is one of say top 5 elisp expert i know.

and i think he's about the only one, who writes emacs tech blog and writes well and in depth.

he not just know elisp in depth, but, programing and associated computer science.

i can't readily think of anyone else on emacs or emacs lisp.

most other elispers, when they have a blog or opinions, i find them idiotic.

emacs, recommended dropin replacements for standard packages

my own:

ok. that's one too many.

now, a reverse replacement.

The ones i consider actually harmful are:

* s.el f.el, dash.el, god mode, hydra.

They seem convenient, but actually don't do much, adds complexity and bloat. You can do what they do with plain emacs lisp trivially.

The ratio of power/simplicity is the key.

recommended dropin replacements for standard at reddit emacs

learn emacs source code to master computer science?

when i was younger, at one point i thought of studying emacs + elisp as a way of getting into or mastering “computer science”.

turns out, that was a very silly idea. You can master emacs source code but would learn basically 0 computer science and gain very little industrial coding skill. (as with respect to get a programing job. If you master emacs source code, but have no other coding experience, you probably won't find job. Sure you can, in the 1 job per year niche. (but, of course, for some, you might become star coder. But, for such person, he would be regardless of emacs.))

though, Matz the ruby guy, studied emacs lisp and created ruby, based on it.

[see Ruby Creator Matz on How Emacs Changed My Life]

its like this. Would you be a great writer, or get a writing job, if you, say, mastered Shakespere's play?

depends on what's your interest and goal, you probably better off to write a web app, read general programing book, computer science book, instead of looking into emacs source code.

but, if your focus is to contribute to emacs, then, yeah, and you do need to read emacs lisp manual.

as to how to approach emacs source code... i guess just dive in. e.g. say you don't like some command's behavior, or you find elisp lacking some function. You look at their source code, by describe-function, and soon you'll dig into from elisp to C. And, maybe, one thing leads to another.

from how to read and understand gnu emacs source code at reddit emacs

Hello, my name is rms, YOU belongs to me

emacs has ido-mode, but it doesn't cover M-x or C-h f. icomplete-mode does, but its UI is way inferior. and complete-symbol and hippie-expand adds to the total confusion.

each time these are brought up in emacs dev, one ball of philosophical flamewar flies, hundreds of debates and arguments, gouging each other's eyes. End result is nothing is done.

then, there's MELPA, of warlords, each oneupmanship other, for no money but fame. “Try Me”, “I'm Modern”, each bottle cries. And rms considered them foreign, wants people to fold to “GNU”, and sends an army to get them to switch from gpl2 to gpl3. Hello, my name is rms, YOU belongs to me.

Rms, lives in the woods, haven't been coding for like 20 years. Every few months, makes a outlandish statement. Like, Can somebody make emacs into Microsoft Word? What is magit? and why isn't it in GNU emacs? Can somebody make emacs change font size?

then, undying woodworkers crawl out of the woodwork, with suckling millennials, defending rms, like, a god. rms is always right. He sees the future!

The emacs dev list, has this culture of communism commune, where, every clueless joe is “equal”, and voices shit freely. So, any issue, is a debate ball, from all corners of the earth. No process. No rule. We are cooperative peace on earth, the heaven of equal opinions!

One'd expect that code contribution rules in emacs dev, at least. Well, get in line, regardless what celestial deity you are. Prostrate and bow to the GNU. Then, we might look at what your problem is. Then, mention ye code again. If it survives feast of opinions. Beg again. Maybe.

this emacs dev problem comes up every now and then thru the years, by many coders, big and small names, old and new. (reddit, hackernews) Each time, some, e.g. abo abo, eli, insist and deny, any problem whatsoever. gnu people are nice, emacs dev is smooth, rms is god, all's well.

ok, comes to be thinking, what if i am to lead emacs.

ok, first thing, axe all platforms other than mac, windows, linux.

then, axe, without mercy, any deprecated or obsolete code that's more than 10 years old.

then, axe, the common lisp fk in emacs lisp. Aggressively suck in the newer replacement from melpa people.

then, axe, anything complex, and anything approaches of a hack.

emacs window/frame management problem

an emacs frequently asked questions, the window/pane config reset problem. https://www.reddit.com/r/emacs/comments/7evidd/windmove_shortcuts/

my reply

that's a frequently asked questions, comes up every few months.

Best solution, is to stop 1-window full-screen workflow. Because, all sorts of emacs commands will constantly pop up and split your nicely setup panes. You'll have to fight it every few minutes.

This 1-window style came from terminal and IDEs. The former, are conditioned to have just 1 window (unless you make another connection to server). The latter, the IDEs, are based on pallette idea, where you have a fixed pane config, and every tool is predefined to sit in some pane/drawer/tab that lets you open or collapse them.

there are various packages that help you “reset” your windows config. But they just add more work to your fingers.

Instead, use 2 windows side by side workflow. This way, your window config never changes unexpectedly. And, operating system provides much more flexible and powerful ways to control them. (e.g. Mac expose, or various linux tiling managers, and virtual screens) And, you can now fully utilize emacs split/unsplit horizontal/vertical on any window as you work, view different parts of a buffer, run calc, calendar, dired, shell, etc. Fluid and flexible.

lisp is dead

today is probably a good day to declare lisp dead. For a few years now, you don't hear lisp as cool stuff anymore. Not even much clojure. A new generation of programers, unceremoniously took place.

I think time moved on. No new Common Lisp coders. Scheme quietly went away, replaced by pyret (python) by themselves. Clojure struggle among tons of new langs, confined in enterprise coding on java platform. emacs lisp remain in handful of emacs users.
