emacs meetup at San Francisco, Saturday, Aug 18, 1 to 3 pm. https://www.meetup.com/Emacs-SF/events/253565625/

emacs, create link of word etymology

here's one of my helper command.

(defun xah-words-word-etymology-linkify ()
  "Make the current word into a etymology reference link.
Version 2018-08-16"
  (interactive)
  (let ($p1 $p2 $input $result)
    (if (use-region-p)
        (progn (setq $p1 (region-beginning))
               (setq $p2 (region-end)))
      (progn (setq $p1 (line-beginning-position))
             (setq $p2 (line-end-position))))
    (setq $input (buffer-substring-no-properties $p1 $p2))
    (setq $result (concat "etymology of <a href=\"http://www.etymonline.com/word/" $input "\">" $input "</a>"))
    (delete-region $p1 $p2)
    (insert $result)))

i've been using the above command for maybe 5 or more years for my “Wordy English” blog.

since i work in html raw, i have lots of these. the way i work in html is similar to most using org mode.

so if you are a org mode user, you can also easily create a command that generate links to etymology of the word under cursor. and you can press a button to look it up. and also publish it. (e.g. if you blog about literature stuff a lot)

emacs htmlize.el, not convert tab to spaces inside pre tag?

just submitted a bug report.

https://github.com/hniksic/emacs-htmlize/issues/21

is it possible to not convert tab to spaces inside pre tag?

in golang, its a community convention to use tabs, enforced by the bundled tool gofmt. (and i think tabs are critical in makefile.)

I write tutorials. So my primary use of htmlize is to convert programing language source code to a htmlized form. With golang, this maybe be a minor problem. thanks.

i wonder if it is practical to use this to implement automatic formatting of lisp code.

see Elisp: Automatic Code Formatting, Auto Indentation

See also: Emacs: Why I Don't Use paredit

Emacs: Insert Random Number/Hex/String

updated code for xah-insert-random-string. Now will use any A to Z, a to z, 0 to 9. Before, it uses only lower case, and avoids some vowels etc that may look like other, e.g. 1 l, o 0 O.

emacs indentation problem and universal framework

emacs lisp. going to do a biggish job. write a tutorial for how to implement programing language indentation in major mode. and do it for my xah-js-mode.

it'll take about 6 hours.

emacs lisp. to write a indentation command, is a clean text processing task. given a text file and cursor position, you want to add certain tab or space in beginning of certain lines. Not trivial, but nor really difficult.

However, if you want to follow emacs convention, the task becomes somewhat more complicated. because emacs has a very stilted convention that's also half-assed. if you publish your mode, you basically have to follow this convention, else hacker types no welcome it.

emacs has 1 major problem. it tries to have a universal system, so if all major mode follows it, then users can make 1 config across all major modes. e.g. set up tab/space for indentation, indentation commands, comment, syntax coloring, completion, etc.

the problem is, some of these systems are really lousy. That's why you end up with each major mode doing its own way, or inventing complete new UI. Most notable is completion, indentation/tab/space setup.

Note, the “universal system” is modern jargon is Framework or API. However, in emacs lisp, they are not really that, because the entire elisp doesn't follow API mindset, partly by intention, cuz rms wants it to be “free coding”, or, fear if there's API, 3rd party will hijack.

2018-04 gonna have to get up and walk for an hour per day. Else my left hand is going to crippledom fast.

notes on today's emacs meetup Mountain View. 2018-07-28

today's emacs meetup was fun. https://www.meetup.com/Emacs-SF/events/252240839/attendees/

We met Jeff T, Michael W, Leslie L, Harry S, Arthur A G, David S, Huynh K, Gaurav J, and me Xah L.

Gaurav provided us with a super nice conf room with a view from 10th floor! and we had few nice light presentation on the spot!

emacs meetup SF has a github page https://github.com/Emacs-SF/

and i think @JaafarTrull keep notes on it. Not speaking for jeff or team, but i think we are looking for more lightning talks, or longer presentations. So if interested, get in touch with jeff.

Harry gave a short talk about using emacs with UI to “the best” dictionary, 1913 Webster's. you download a dict source file, a star dict command line UI, and a emacs UI wrapper. you can see setup at https://github.com/hrs/dotfiles/blob/master/emacs/.emacs.d/configuration.org#look-up-definitions-in-webster-1913

irreal wrote about using emacs with 1913 Webster dictionary at http://irreal.org/blog/?p=6546 am going to set it up myself. I'd love it. Yes, what dictionary you use matters.

am a dictionary nerd. I used to lookup words some 50 times a day, for 20 years. Still do 5 or so times daily now. You can read up what i have to say at American Heritage Dictionary vs Merriam Webster Collegiate btw, the worst dictionary is the one bundled with Mac.

For dictionaries, my ranking is:

  1. American Heritage.
  2. Merriem Webster UNABRAGED (weights a brick).
  3. 1913 Webster, WordNet, Google, wiktionary, are all rather lackluster, but each has its uses.
  4. Merriam Webster Collegiate, which is what you see everywhere and online, is the worst.

Well, the one bundled with Mac, which is “New Oxford American Dictionary”, is worser than worst. see American Heritage Dictionary vs New Oxford American Dictionary

by the way, if you want emacs commands to lookup any online dictionaries (or web search, function doc lookup etc), try xah-lookup.el Emacs: xah-lookup.el, Lookup the Web can setup to use emacs builtin browser eww

for next emacs meetup in Mountain View, i think am going to bring my Kinesis Advantage2 Keyboard Kinesis Advantage2 Keyboard Review so you guys can try it. it'd be fun.

another thing i learned from the meetup is, @JaafarTrull gave a lightening talk about emacs lsp mode. LSP is Language Server Protocol. It allows emacs to connect to server dedicated to parsing langs. So you get better completion etc due to real parser at server.

autoload and require

answer to reddit question.

autoload is more for interactive use purposes. require is for loading libs.

so if you are writing lisp code and need another package, always use require.

if you are setting up init file, best to set up autoload when possible. Because that way, it saves startup time. The file is loaded only when user actually calls it. Best example of such are programing language modes.

see Elisp: require, load, load-file, autoload, feature

emacs default key

https://www.reddit.com/r/emacs/comments/8y5tfv/who_here_actually_likes_emacstheeditor_as_opposed/

my reddit post

Perhaps, look at it this way:

most emacs users use emacs default keys because it's the default. This is same with qwerty vs dvorak situation, or any tech. It takes quite some effort to change things out of ordinary. e.g. first one must be aware there are alternatives. This also rules out most newbies for not using default key.

for those who use spacemacs and change it to emacs default key, probably because, they already have experience with emacs. The default keys are burned to muscle memory, which is hard and painful to change.

default key has other advantages other than habit. e.g. dvorak layout is more efficient, but everytime you goto library, or use other computer, it's a problem. And other people can't type on your keyboard. This also applies to PC keyboard vs those fancy ergo ones such as ergodox.

another advantage of default is that it's the “official”. As with most other things, you want to stick to official. Unless one really learned otherwise, such as by words of mouth and established a trust on X.

vi is more popular simply because vi is bundled with unixes. Emacs require install. This is still true today on linuxes.

people switch away from default mostly due to need. e.g. those who got hand pain. Those who have interest in efficiency. (which may be the same reason that drew them into emacs in the first place)

i used emacs default keys 100% for the first 6 years of my emacs life.

elisp name “my/” prefix, slash or hyphen?

reddit question https://www.reddit.com/r/emacs/comments/8waf1y/whats_the_deal_with_my_notation/e1v4ptp

my answer.

as many said, it's a convention. This convention, is not official though. Official gnu emacs stance is to use hyphen.

technically, slash is slightly better, as it distinguishes name space purpose from word separator. However, because it's not gnu convention, so it has problems. eg say you dev all your packages with slash. But one day your package becomes popular, and you are considering to assign paper to be part of gnu emacs. Then, you got the problem of changing all your names, thus break all init out there...

real solution, is to get FSF emacs team to introduce namespace. It is not hard to do, if one do not consider 100% backward compatibility to 30 years back, but typically they want that, for reasons in my opinion is not practical. Among other social problems of gnu emacs dev. Major one is that in the fsf culture, no one really takes a leader role to get things going. It's arguments and arguments, and rms now and then say things by hegemony. Technically he should not have power over any non-political emacs issues, as that is understood to be the current maintainer. But in reality, far from it.

besides the slash vs hyphen issue, there are others, e.g. using question mark for all predicate functions. (i.e. function that returns true/false). The question mark is superior, and is the convention in scheme/racket lisp, ruby, clojure. Emacs lisp tradition is p, however, it's quite lousy, as lots functions end in p but is not predicate, and for predicate, some are “-p” some just “p”. Again, we have the backward compatibility vs progress problem. Note, many popular packages on melpa, use the question mark convention. e.g. the package “dash”.

Emacs: Insert Date Time

minor fix. now if universal-argument is called before, and there's selection, the selection is deleted only after the choice of format is made. (before, it delete selection first, then prompt choices, which is not good, because sometimes you want to see what's the format used before you chose.)

here's the solution i use to avoid Shift key

might try turn on Sticky key in your operating system. (usually under accessibility/disabled-help)

i've tried to ban it completely. Ban Shift Key

currently i use xah-upcase-sentence Emacs: Upcase Sentences and xah-title-case-region-or-line Emacs: Change to Title Case and xah-toggle-letter-case Emacs: Toggle Letter Case for most of my upcase needs.

for paren/bracket, i use lead sequence 【Space e t】 (dvorak) in xah-fly-keys. Emacs: Insert Brackets by Pair

if you are using ergodox, keyboardio, etc that has programable firmware, you can set a thumb key (such as Space Enter ⌫ Backspace) to double as Shift when held down. Amir Rajan suggested this:

writing a major mode, free form or not

currently fret about whether my xah html mode should be based on: ① fundamental-mode ② #emacs 26 mhtml mode. With ①, am free to have it however i like. simplicity. but it won't syntax color html from the wild “correctly”. Though, that's not that important.

problem of basing on emacs html-mode or the new mhtml-mode is that, the code becomes EXTREMELY complex. you got 3k lines mucking under it in sgml mode. you don't have control or flexibility, unless u understand those 3k lines

xah-html-mode itself is 3.5k lines. They are text transformation code. Only 0.2k lines are about syntax coloring.

base programing language major mode on prog-mode?

in emacs lisp, it's common to hear recommendation that programing language mode should be based on prog-mode. after looking at the code of prog-mode, am not sure it's a very a good idea.

I think there's not that much benefit for doing so. Meanwhile, it limits flexibility of major mode design. Also, just a tiny bit. So overall, either way, i think it's not that useful.

starting to casually write about emacs 26 new features.

am starting to casually write about emacs 26 new features.

here's the news file Emacs 26.1 New Features (released 2018-06)

am going to edit it as i read it.

one problem of emacs is that its features file, is cryptic. i've used emacs for 20 years now and am reasonable expert at elisp, but half of “NEWS” file i don't understand, without spending lots time digging into each. Same for others who've used emacs for 20+ years.

the problem, is not because oh emacs is so big and powerful. That's what you like to hear. The problem, is actually the writing, and the mind set of the devs. It is written, in a style that makes it incomprehensible.

This is similar to why academic papers (e.g. on computer science, programing language research) are filled with jargons, UNNECESSARILY. Academic papers are that way because, its main function is not to distribute knowledge, but, as part of system to promote the writers, among peers. The culture induced the style. Similar for government bureaucracy papers such as DMV.

for emacs, the problem is, emacs dev has this cult of it being the supreme, lisp machine, oldest, etc. So, the writing style sprung from a mind set of that. Part arrogance, part 30 years old jargons, and part inept geekdom who are unable to communicate to the public.

however, when you read emacs doc, the emacs folks want you to think, it's incomprehensible to you because emacs is extremely advanced.

No, today, emacs is rather one of the least advanced software. A web browser, is a magnitude more complex. Think of its JavaScript compiler, JavaScript runtime system, builtin debugger (the console), networking parts, GUI elements, display system, extension API, etc. Just about any gaming software is a magnitude more complex too. And, Atom editor, Visual Studio, or IntelliJ, all are technically more complex and advanced than emacs.

and by the way, emacs calls its “release notes” as “NEWS”. Another addition to incomprehensibleness.

  2. Alt+x desktop-save-mode to turn it off.
  3. restart emacs.

2018-06-07 addendum: apparently, that does not fix it. When you have desktop-save-mode on and restart , the problem comes back. it seems, i have some init that cause emacs to save something bad about frame config to the desktop-save-mode file. But note, this did not happen in emacs 26.0.91.
