Pppery moved page Module:Pelagic01 to Module:Sandbox/Pelagic/01 without leaving a redirect: Naming convention for test modules

New page

-- Baby steps with Scribunto and Lua

--[[ Things I'm unsure of or probably doing wrong:
* Convention for per-user collections of modules,
could I use subpages like Module:Pelagic/Test01 ?
* Haven't read the coding conventions yet.
** Caps? camelCase? underscores?
* Existing general utility modules? (as opposed to template-specific modules)
]]

--[[ Annoyances:
* iOS keyboard automatically converts - - to —,
it would be nice to have a button to comment/uncomment a line.
* Hardware keyboard on iOS types curly quotes not straight quotes.
* Tap and drag on a touchscreen selects characters and
can't be used to fine-position cursor.
]]

--[[ Nice features:
* Editor starts next line at same indent level,
automatically outdents when you type "end".
