Lua utilities

[dndrks]

thought it'd be useful to outline any utilities folks have pulled from norns for their iii sketches!

i've been using:

• util.round
• util.clamp
• util.linlin
• util.wrap

[tehn]

yes indeed all of those should be added, will get them in the next build!

[tehn]

trent suggested the quote lib from crow as a table serializer

https://github.com/monome/norns/blob/main/lua/core/crow/quote.lua

[tehn]

250108 adds

• linlin
• wrap
• round
• clamp

[tehn]

still working on a table-to-string lib paired with some helpers for storing to flash.

also extending the midi helpers.

open to other additions!

[tehn]

upcoming:

• musicutil (streamlined)
• slew

[dndrks]

mm! is there any benefit to adding a helper to print booleans (for debugging)? i know we can use ps("%d", 1==3) or print(tostring(1==3)), but both feel like an extra move for a frequent case. eg. pb(1==3) feels fun!

[tehn]

yes absolutely. on my list is to improve print in general to do a lot more things that aren't in place, boolean included

also want diii to assume that if you leave a variable on the command line that it should be printed.

ie

x

infers print(x) like the standard lua repl
