farmbuyer@1 1 --[[
farmbuyer@1 2 Not really meant for public use. Stuff that I keep using everywhere and
farmbuyer@1 3 got tired of reimplementing, or even copy-and-pasting. The notes here are
farmbuyer@1 4 reminders to myself.
farmbuyer@1 5
farmbuyer@1 6 Library contents:
farmbuyer@1 7 - author_debug
farmbuyer@1 8 Evaluates to true if I'm hacking on something.
farmbuyer@1 9
farmbuyer@1 10 - tableprint(t)
farmbuyer@1 11 A single print() call to the contents of T, including nils; strings are
farmbuyer@1 12 cleaned up with respect to embedded '|'/control chars. If there is a
farmbuyer@1 13 global LIBFARMPRINT function, it is called with the cleaned-up T instead
farmbuyer@1 14 of directly calling print.
farmbuyer@1 15
farmbuyer@1 16 - safeprint(...)
farmbuyer@1 17 Same as tableprint() on the argument list.
farmbuyer@1 18
farmbuyer@1 19 - safeiprint(...)
farmbuyer@1 20 Same as safeprint() but with index numbers inserted. Ex:
farmbuyer@1 21 safeiprint(a,b,c) --> <1>,a,<2>,b,<3>,c
farmbuyer@1 22
farmbuyer@1 23 - CHAT(n)
farmbuyer@1 24 Returns a function suitable for assigning to LIBFARMPRINT, directing all
farmbuyer@1 25 output to builtin chat frame N.
farmbuyer@1 26
farmbuyer@1 27 - t = StaticPopup(t)
farmbuyer@1 28 Fills out "typical" settings inside T, especially if T contains any kind
farmbuyer@1 29 of editbox:
farmbuyer@1 30 + cannot accept an empty editbox
farmbuyer@1 31 + pressing Enter runs OnAccept
farmbuyer@1 32 + editbox grabs keyboard focus
farmbuyer@1 33 + OnAccept runs with editbox's text in dialog.usertext
farmbuyer@1 34 Returns T.
farmbuyer@1 35
farmbuyer@1 36 - nullfunc()
farmbuyer@1 37 Empty placeholder function. Will be less useful if WoW ever moves to Lua 5.2.
farmbuyer@1 38 This is a fascinating and educational place to insert print calls...
farmbuyer@1 39
farmbuyer@1 40 - tabledump(t)/dumptable(t)
farmbuyer@1 41 If author_debug, this runs the builtin /dump command on T. Otherwise nothing.
farmbuyer@1 42
farmbuyer@1 43 - DoOnceNextUpdate(f)
farmbuyer@1 44 Runs F on the next frame refresh cycle. Multiple calls in one cycle will
farmbuyer@1 45 stack LIFO. Calls *while* processing the stack are safe, and will be stacked
farmbuyer@1 46 up for the next cycle.
