Grapher issue?

Ok, so Supriya appears to be running here on windows. However, when I tried the ‘Quickstart’ part of the documentation here: http://josiahwolfoberholtzer.com/supriya/#quickstart, I get this:

C:\Windows\System32>py

...     Out.ar(0, [sine * envelope] * 2)
...
>>> supriya.graph(simple_sine)

Looking in the C:\Users\falkd\AppData\Local\supriya\supriya\Cache\, I found that Graphviz had successfully generated the 2022-08-14T06-02-39-722229-b70cc34.pdf which I can open in Acrobat for example.

Generally, when using windows paths in python, I’ve found that using double backslash yields better handling of names with blankspaces, dots and numbers. Like this:

>>> open ('C:\Users\falkd\AppData\Local\supriya\supriya\Cache\2022-08-14T06-02-39-722229-b70cc34.pdf')
  File "<stdin>", line 1

                                                                                                     ^

OK, I can work with that. Will let you know when the libraries are updated.

Happy daze! 😀

I’ll let you know if/when I find anything else. For now, I’m really stoked on digging into the intricacies of Supriya…
