Hi all,

I would want the following: Whenever I press Ctrl-S to save a patch in Puredata, I'd want the timestamp of that action to be written in a message box; then, I could do a:

[loadbang]
|
[Fri Nov  9 11:39:07 CET 2018(
|
[print]

... and have the timestamp of the last save, be output whenever I start a patch.

So, is there a way to detect a save within Puredata?

Hi sdaau_ml

I am not aware of a vanilla way to do it (through a simple tcl plugin might be done)

but with iemguts externals you can use [receivecanvas] that will tell you all about the current canvas states (mouse, key etc...).

[receivecanvas]
|
[route savetofile]
|
[print]

You will get a list with the name of the file and the path on save action.

Cheers

@sdaau_ml Zexy had an object [time] which could also get gmt [time gmt] from the system clock.
time_windows.zip
Unless Deken can provide it you would have to download extended for your system and extract it (if it works for your system).
It could probably also be "got" through the tcl code, if you have [sys_gui] available.

Many thanks @60htz and @whale-av - for letting me know exactly what I needed to know

@sdaau_ml Sorry, I missed [date] which you might need as well.........also Zexy.... time_and_date_windows.zip
David.

if you are in a linuxy environment, you can use the [shell] you can use 'date -r filename.pd' which will tell you the last modified time of the file in question. Why write a patch to replicate an inherent quality of files in the OS?

Hi @sdaau_ml I was intrigued by how this might be done in Windows (you didn't say which OS).
So I came up with this abstraction that does the trick.
The tradeoff (there's always a tradeoff) it creates a text file in the same directory as the patch.
Requires [ggee/getdir] and [motex/system] and the name of the patch
create the object in your projects main patch as ** [last-saved the-name-of-your-patch.pd ] **, add a bang to the inlet and a message box the outlet. A text file of "the-name-of-your-patch.pd-Timestamp.txt" is created or updated each time you bang the abstraction.
I originally used [iemguts/canvasname] to get the patch name but couldn't use it in an abstraction.

last-saved.pd

Thanks again for the discussion, all:

Hi @sdaau_ml I was intrigued by how this might be done in Windows (you didn't say which OS).

I'm on Ubuntu 18 / Linux, so [shell] would have been great, but not for patches that would run in vanilla...

Thanks again!

What about the new [savestate] object in Pd 0.49? I think it does exactly that. You get a bang on the left outlet when the patch is saved and a bang on the right outlet when the patch is loaded.
