Here is the announcement. Most delightful Smalltalk interpreter ever.
Hear, hear! Org-Mode 8.3.5 Is Released!
After switching between Emacs/Org-Mode and RStudio one hundred times you start to wonder if you ought to export your Literate Org-Mode documents to RMarkdown and try it out for a while. ox-ravel lets you export Literate Org-Mode documents to RMarkdown, and more.
The announcement is here.
- Great way to start the summer
- Better for developers, too :)
- Free for non-commercial use
- Paid for it before as it was worth it
- Hope better pricing attracts more users
- Performance speedups
- Hashed array type speeds things up
- More cross-platform tools including functions and IDE
- RIDE will go open-source
- More/easier Emacs integration?
- Workspace can reference Unicode files
- Changes are stored back in the file
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
