I am trying to make a video recorder in pd for an installation. I want the video files to be recorded sequentially, with a timestamp of sorts in the filename, something like:

chan0_recording_yyyymmdd_HHMM.mov (e.g. chan0_recording_20090420_2134.mov)

I find it very very difficult to do string formatting in PureData, the only objects I know that dome something of the sort are [makefilename], [l2s] or [makesymbol]. I have made this little patch to fool around with these a bit and see if I can get what I want, but I'm not being very successful. Also, it's a rather crappy solution, the patch is too complex.

Is there another way around this? Maybe an object that does what sprintf does?

Any help is appreciated. TIA.

Hi zilog

there is a [sprintf] in extended. Cyclone lib i think..Are you trying to keep it vanilla pd?

Not really, extended is also fine. Unless of course there's an elegant and simple solution in vanilla pd.

Thanks a lot for your tip!

Just for future google miners, here is a solution based on the [sprintf] object boonier pointed out.

Anything elegant that is plain pd with no extensions is still elusive. Solutions still welcome.

...elegant once you've wrapped it up into an abstraction and don't look at the inards!

I think it would involve feeding the result of [makefilename] into another [makefilename],

and so on. I haven't attempted it though..i dunno

[chan0_recording_$1_$2.mov(

is another possibility

yes, since recent pd you can build symbols in message boxes even if they don't start with a $

ahh, much simpler there you go
