[query] Dot notation error in Wireviz

[akikinho]

Hello Wireviz Team,
I am trying to understand the usage of dot notation in Wireviz but unable to replicate as it throws an exception 'First item not found anywhere.' The operating system is Microsoft Windows 10 Pro Version 10.0.19045 Build 19045 and the Wireviz version is wireviz 0.3.2. Can you please help?

connectors:
  X:
    pinlabels: [GND,B-,A+]
    color: GN
    
cables:
  W:
    colors: [BN,YE,GN]
    shield: true
    
connections:
  -
    - X.: [1-3]
    - W.W1: [1-3]
    - X.: [1-3]

The dot notation is new from WireViz v0.4 - see docs/CHANGELOG.

Thank you @kvid.

Please provide your Python version (python -V). However, your latest error message is similar to what was reported in #344, so I guess the issue is already fixed in PR #346 that is merged into PR #365 (work-in-progress) that will become our next release when finished.

Try this development version to see if it solves your latest problem:

pip uninstall wireviz
pip install git+https://github.com/wireviz/WireViz@release/v0.4.1-rc

Thank you @kvid. The python version is Python 3.12.3 and it works with the development version.

@akikinho - I just deleted your comment in #293 because it seemed to be a copy of your initial comment in this issue, and I didn't see any relation to what is discussed in #293, so I guess it was added to the wrong issue by a mistake. Please correct me if I'm wrong.

@kvid, it is correct and thank you. I have a new question.
In the dot notation, I found that the connector name is missing in the .svg file

connectors:
  X:
    pinlabels: [GND,B-,A+]
    color: GN
    
  Y:
    pinlabels: [SH,B+,A-]
    color: RD
    
cables:
  W:
    colors: [BN,YE,GN]
    shield: true
    
connections:
-
    - X: [2]
    - W: [3]
    - Y: [3]
-
    - X.: [1,2,3]
    - W.W1: [1,2,3]
    - X.: [1,2,3]

See https://github.com/wireviz/WireViz/blob/v0.4/docs/syntax.md#autogeneration-of-items

Names of autogenerated components are hidden by default.

Your X. generates unnamed connectors. You can optionally specify a name after the dot, like in your W.W1 cable.

@akikinho - Judging from your progress in #396, I assume this issue is resolved, and I therefore close it accordingly. Feel free to reopen at any time if needed.
