APL might pique your interest, but not enough for you take final step forward to start hacking with it. GNU APL is there, waiting for you. Still not enough?
(use-package gnu-apl-mode :ensure t)
or download it, extract it, and load it with a
(add-to-list 'load-path "~/path-to/gnu-apl-mode") (require 'gnu-apl-mode)
Do you have any more reasons not to start hacking with GNU APL and Emacs?!
Never having studied a package like this before, it is educational. It is also revealing how much love and labor went into this delightful package.
Thanks you Elias Mårtenson; hear, hear!
Google+ has an APL Group now!
Org-Mode code blocks are verbose and lovable for literate programming. Rasmus wants to use the raw literate document for a presentation though, so that verbosity won’t do. He explains here how to prettify code blocks. The value-add here is that he doesn’t have to weave (export) the document for it to look great in the presentation; it already does directly in the Emacs buffer.
Here is an easy way to use both Emacs and OS X modifier keys when you are inside Emacs:
Toggle the right-option and function key to switch between using them inside Emacs and using them for OS X.
I used Karabiner to make
LEFT CONTROL when chorded. I used OS X to make
CAPS LOCK be
CONTROL. I didn’t change
COMMAND. I made this change because Emacs couldn’t ignore the key-event when it was coming from Karabiner.
Here is the code:
(help/on-osx (setq mac-control-modifier 'control) (setq mac-right-control-modifier 'left) (setq mac-command-modifier 'meta) (setq mac-right-command-modifier 'left) (setq mac-option-modifier 'super) (setq mac-right-option-modifier 'left) (setq mac-function-modifier 'hyper) (defun help/toggle-mac-right-option-modifier () "Toggle between passing option modifier either to Emacs or OS X." (interactive) (let ((old-ropt mac-right-option-modifier)) (setq mac-right-option-modifier (if (eq mac-right-option-modifier 'left) 'none 'left)) (message "Toggled `mac-right-option-modifier' from %s to %s." old-ropt mac-right-option-modifier))) (defun help/toggle-mac-function-modifier () "Toggle between passing function modifier either to Emacs or OS X." (interactive) (let ((old-func mac-function-modifier)) (setq mac-function-modifier (if (eq mac-function-modifier 'hyper) 'none 'hyper)) (message "Toggled `mac-function-modifier' from %s to %s." old-func mac-function-modifier))))
Just went through most of Zark’s Dyalog APL Tutorial
- Nice to pick and choose topic areas
- Seems to serve both inexperienced and experienced programmers
- Lots of examples
- Great for virtual input from an experienced APL programmer for you
Aaron Hsu blogs on APL here; all good reads.
Here are three ways that I might want to quote content in my personal notes with Org-Mode:
My friends really might want to know how.
