Emacs: yank a line multiple times from the kill ring
Today I needed to copy a line multiple times in emacs. I needed 8 copies, but how to do that in emacs short of pressing C-y to yank 8 times? My initial guess was to try C-u 8 C-y but that yanks the 8th item from the kill ring. Fuco on #emacs supplied the awesome…

UPDATE 2013-05-03: After writing this I found out my approach was incorrect. I have since removed the code as it was not useful. Dan’s team was kind enough to point me to Virgin Australia‘s site. If you inspect the source and search for hreflang, you’ll see how it should be done. /UPDATE After seeing the…

Launching cygwin emacs from native win32 programs
My business’s accounting program, which I’ll call Canopus, has issues. One of which is that it assumes wordpad.exe will be in c:\windows.

My second Project Euler solution. Project Euler No. 2 This was a little tougher to solve than No. 1. I decided to use recursion to solve it, and as I haven’t had to write anything that used recursion since I was at Uni, it took me a while go remember how to do it. Also,…

OAuth 2.0 in emacs – Part 4
Finally managed to authenticate against WordPress.com using the oauth2 library. Here is my sample code which returns an access token. (let ((code (oauth2-request-authorization “https://public-api.wordpress.com/oauth2/authorize?blog=jasonblewis.wordpress.com” “2194” “” “” “https://emacstragic.net”) )) (oauth2-request-access “https://public-api.wordpress.com/oauth2/token” “2194” “” code “https://emacstragic.net” ) ) WordPress at least seems to be fussy about what you use as the Redirect URI. It needs to…

emacs elisp first attempts
For a long time I have wanted to learn elisp in emacs. I tried the various tutorials but I get bored of them too quickly. Too many words not enough action for me. I was reminded of Project Euler by Daniel Silverstone so I thought I’d have a crack at one of the problems. No.…
