Call to GXMVU.path_plot() just stops about gxpy HOT 4 CLOSED

GXMVU.fight_plot() just stops too.

from gxpy.

Just remembered what causes this. A group was not started. I'll correct in Python, but we should address the behaviour for 9.3+.

from gxpy.

@jbgeosoft understanding that the underlying core is asserting, we need a better behaviour to expose the assertion, or we need to be able to document it. Here is a code snippet that asserts at the GVMVU call. Comment out the line to see expected behaviour. The bug in the Python code is that GXMVU is writing the a view that has not started a group, and asserts rather than raise an error. Before fixing the assertion we can use this example to think about how to provide the assertion information to a developer using the API.

import geosoft.gxapi as gxapi
import geosoft.gxpy.gx as gx
import geosoft.gxpy. map as gxmap
import geosoft.gxpy.view as gxview
import geosoft.gxpy.group as gxgroup

gxc = gx.GXpy()

with gxmap.Map.figure((0, 0, 1000, 1000)) as gmap:
    with gxview.View.open(gmap, "data") as v:
        gxapi.GXMVU.arrow(v.gxview, 500, 500, 450, 450, 0.5, 30, 1) # asserts
        with gxgroup.Draw(v, "arrow") as g:
            gxapi.GXMVU.arrow(g.view.gxview, 500, 500, 450, 450, 0.5, 30, 1)
