thatwist / CapsLockCtrlEscape.ahk
Created July 30, 2019 10:46 — forked from sedm0784/CapsLockCtrlEscape.ahk
AutoHotkey script to map Caps Lock to Escape when it's pressed on its own and Ctrl when used in combination with another key, à la Steve Losh. Adapted from one that does something similar with the Ctrl Key on the Vim Tips Wiki (http://vim.wikia.com/wiki/Map_caps_lock_to_escape_in_Windows?oldid=32281). (Plus contribs from @randy909 & @mmikeww.)
g_LastCtrlKeyDownTime := 0
g_AbortSendEsc := false
g_ControlRepeatDetected := false
*CapsLock::
if (g_ControlRepeatDetected)
{
return
}

Checks Wirth–Weber precedence relationship. This is an old piece of code I wrote in university - this is scary but it works.

thatwist / phone_number_to_words.scala
Created December 6, 2017 18:47
Parses a phone number and finds all possible words based on numpad-to-letter mapping and dictionary
trait SolutionDef { self: DictionaryDef with DebugDef =>
/*
* based on the example included:
* 866-5548 -> tool-kit
* the assumption is made that '-' symbol position doesn't matter
* and it's not a word divider
* e.g. any of those groups of numbers can make up a final sequence of words:
* 86 65548, 86665 548, 86 655 48, etc.
*
* here is no phone number format specified as every coutry has its own
