it's been done before but this was my take on a simple way to livecode with [expr] in pure data - it leans into being as simple as possible so its easier to take it and use it for something else (bytemidi, drum triggers, using [expr~] instead for rampcode(?)).
a thing c and [expr],[expr~] share in common youcanwritefunctionswithoutanywhitespace so there didn't have to be any messy patching dealing with that - as an example it's being used for bytebeat (with some caveats about floats and things that [expr] doesn't like like sending it 0 with [value] at audio rate. It's pretty easy to change up - for example - pick a new big number and small number to the [mod ]s and you can make triggers for a sequencer. you could modify it to be [expr~] by changing the [message< , could stack more livecode inputs to control other things like the update frequency. anyway

"this is an experimental way to allow dynamic repatching in PD and do livecoding just using pure data.
livecoding requires – 1) an obscure language – pure data is a dataflow programming language 2) an obscure text editor – well I cant think of a more arcane one than a visual programming language so check that off for pure data too.
Known limitations – it’s a little crashy – the List message box doesn’t like backspaces.
32 bit floats lose precision and can make it a seem a little wonky – not all patches will sound the same because Pure Data uses 32 bit floats for effeciency. so objects with / % >> will effectively “chop” off and the patch will sound different than a real bytebeat (or whatever you use this for) after a while or seem like it can just plain quit. The numbers either got too small or too big to work with 32 bit floats.
Another thing about 32 bit floats, the biggest number PD can count to is 1.6772e+07
Pure data also squashes numbers you get 123456 digits. 1234560 turns into 1.23456e+06. In comments this gets changed after you close, reopen so try cut/paste.
Also I noticed sending 0 into [expr] in the variables makes it unhappy and crash so I avoided it making x and y 1 or bigger.
Anyway – check out
to see it in action – and if you want o use this for something else remove anything connected before and after the spigot objects.public domain / unlicense / fishcrystals out"

dno about all the terminolgy and requirements, but it makes me happy when I see other people being creative and livecode has been a way to get people into doing experimental computer audio and video - probably after working where work is on the computer , personally I saw it as a way to rapidly prototype & it was my very first idea about something I wanted to do with bytebeat and pure data (only took a year! lol) - thanks to everyone in the community & the discord and netpd for making stuff and being helpful and being inspriring
