GH Python External File - No Line Numbers in Out

[silvano]

@eirannejad Please see the below screenshot. The error is given without a line number. Thus it is hard to debug. Unfortunately I cannot share the file. External script file is a must (vim motions user). Is this a known bug? Thanks!

Just FYI, I edited the topic. GhPython is the name of the old IronPython editor. Your screenshot is the new Rhino 8 Python 3 editor.

@AndersDeleuran Thanks, what tag is to be used for Py3? Edit: Got it, GhPython > ghpython.

@eirannejad Upon further investigation, this problem only exists with specific errors that do not show the line number at the end of the error message (the missing parentheses error is one of them). In contrast to that, import errors show the line number at the end of the message.

I don’t know if there are specific categories tags, but I usually post under Grasshopper Developer with tags that relate to the relevant components/languages. See e.g:

Setting Slider Rail Width

Hi All, I find myself often manually dragging the width of sliders to their minimum. This is getting a bit old, so of course I’m trying to script it. As far as I can tell the slider property one needs to manipulate is probably Slider.Rail.Width or Slider.Rail.Size.Width. However I’m not having any luck with either, following the forum pattern for e.g. setting the slider value: 221109_SetSliderRailWidth_00.gh (2.7 KB) Any ideas would be much appreciated in any language. Best, Ande…

Rhino 8 Script Editor Default Type Hint

Hi @eirannejad, I just noticed that the default type hint in the new script editor (CPython and IronPython) unfortunately has been changed back from No Type Hint to ghdoc Object. We had a four year long discussion about this topic for GHPython back here: In brief, I’d much prefer if either (in order of preference): The default type hint was No Type Hint. There was an option to set the default type hint (e.g. under Grasshopper menu). The GHPython neighbour inheritance behaviour (is clunky, …

But whatever works

@silvano Yes. There are a subset of errors (I don’t have a list of all of them) that do not show the error line currently. This is either a technical limitation in figuring out the line number in Pythonnet, or might be a parser issue that tries to grab line number from python exception messages.

Either way it would be great if you can share an example that I can use to repeat and fix the issue.
