setting and setting sys.path for custom directory imports

[dkebler]

I'm trying to import some utility modules located in a different directory from the main be files

according to this
https://github.com/berry-lang/berry/wiki/Chapter-8#behavior-of-import

import will look for modules in sys.path

is sys a predined global??

because if I try to see or set the path using sys.path

print("system path ", str(sys.path))

berry reports that

'sys' undeclared (first use in this function)

Just unclear about the documenation and how to implment what says can be done.

At least in a Tasmota context, you need to import sys to be able to use it.

import sys
print(sys.path())

[dkebler]

that function returns a list so

> sys.path().push("/my/path")
> sys.path()
['/my/path']

but it doesn't survive running berry again (from the command line) so you'd have to reset it as part of a script say. I bet there is a way to set the list at compile because by default on my linux box it's ['/usr/local/lib/berry/packages']

[s-hadinger]

I'm not sure there is an easy way.

Best option would be to extend the berry.c main source to support additional command line arguments, or get it from ENV variable.

I provided PR #289 for an additional command line argument since i also needed it.
Should be good for @dkebler too!
