Lennart Borgman, emacsW32
am wondering how Lennart Borgman is doing. https://www.emacswiki.org/emacs/LennartBorgman He's creator of the emacsW32 distribution for Windows, very popular in late 2000s. I haven't heard from him for maybe 7 years. His website is gone.

Emacs: Spaces to New Lines ๐ very useful
code minor update
in emacs 26, often, half of the screen becomes blank. or it flashes. i thought that โbutterfly smoothโ fix made it worse??
apparently, it seems to be a macOS 10.13 problem. If you are using majove, things seems fine.

grep and find but in pure emacs lisp

gonna do a xah talk show on this today. 3pm San Francisco time. come join me. goto YouTube search xahlee, sub + ๐.
hi u/andreyorst/ , i think some of the posts in this thread is wrong.
Search text in a dir is a fundamental feature in text editors. Relying on external software for core feature is very bad. This contributed in a major way emacs is not popular. Also, the interface between emacs and shell, has many problems when the string contains a lot escape sequences (such as regex) or lots unicode. (i've documented this in detail in the article you cited)
On Microsoft Windows, this is a practical, major, problem.
am going to do live stream talking about this in 2 hours. (3pm San Francisco time, today 2019-06-08).
to do in live stream:
explain what's wrong with emacs not having builting feature to search dir.

emacs long lines problem
#emacs inserted this by mistake. waited for 10 minute still froze. had to force quit. fuck eli and those who pretend emacs no longline problem
xah-fly-keys default to insert mode?
minibuffer is setup by a hook
(add-hook 'minibuffer-setup-hook 'xah-fly-insert-mode-activate) (add-hook 'minibuffer-exit-hook 'xah-fly-command-mode-activate)
i think to do that for magit etc mode , one can add to
- after-change-major-mode-hook
- change-major-mode-after-body-hook
- change-major-mode-hook
ใsee Emacs: List All Hooksใ
i'll write up a tutorial in the xah fly keys customization section. maybe i'll add as default to magit mode. will think about it.

most efficient page up/down, ergoemacs-mode and xah-fly-keys
the page up/down story is somewhat complicated. I used to insist on use the physical keyboard page up/down OR use mouse wheel (must be accelerated OR free spin wheel), which IS THE BEST way to scroll. (continued)
then i got kinesis keyboard, and by keylog i rarely use pgdn key, and the keyboard doesn't have many keys. So, i reassigned pgdn to do switch to last window/app. But sometimes i find i do want to page down (and not using mouse wheel)
So, the Ctrl+9 Ctrl+0 was a last minute kludge. not very happy about that. because the very existence of keybinding will make people use that often. people usually ignore advices, such as argument about how mouse accelerated/spin wheel and pgup/pgdn key are better.
macOS switching to zsh from bash
this is also why, the emacs that ships with Mac is gnu emacs 22, from year 2007. and Richard Stallman also forced emacs repo MELPA by hegemony to not support any packages using GPL v2. FSF has become a scum and irrelevant.

Emacs Lisp Doc String Curly Quote Controversy (2015)
Emacs: Latin to Rune (แฑแขแฟแ) ๐
Updated. Now uses medieval rune alphabet. see Unicode: Rune แ
which font to use
thread on fonts that covers math unicode symbols. I recall DejaVu has it Best Unicode Fonts for Programer
also, google note font suite has the math unicode symbols, i think. I don't remember i verified, but it is intened to cover all unicode font eventually Download Free Unicode Fonts
last resort, is Stix font. It is designed to cover math unicode symbols.

vscode vs atom vs emacs
looks like vscode is now a winner, twice as popular than Atom, even though both are written in JavaScript on Electron.
and now, controversy. https://www.reddit.com/r/emacs/comments/bp72wt/i_might_switch_to_vscode/ (note, it's not written by me)
see the full thread for the question.
here's my answer
i hear you. The problem is, it's actually practically impossible to change basic emacs keybindings. This is why, even evil mode, you have lots exceptions. One can hack to enforce 1 keybinding in all major/minor modes, but that adds too much complexity.
what i do and recommend, is just to do case-by-case basis and on your own init. e.g. when a key doesn't work, find out the exact major/minor mode causing it, then add custome override. again, no receipe on exactly how that's done.

Emacs: Move Image File ๐ code update. now uses ido.
emacs long line problem
goto https://www.ecma-international.org/ecma-262/ , save the file. Open in emacs. #emacs freezes for 30 min. you'll be unable to work with that file. To work on the file, you need to spend 1 hour to finally be able to break long lines.
then there's eli zaretskii, on reddit, insisting emacs don't have long line problem.
