Hello AlterNet,
Does AlterNet provide python code completion example?
Thanks!

Hello,
SyntaxEditor supports various languages including Python.Please have a look at our Quick Start AdvancedSyntaxParsing demo and choose Python language.
Unfortunately it lacks some features like Code Completion.
In the coming release we will support fully-functional Python parser based on the LSP technology.

I've uploaded a sample project that shows Python parser with additional features like code completion and error highlighting here :

I've tried with the 6.1 demos (Advance Syntax Parsing & WPF version),
Select Python
After the f.Close() line, I tried f. (crtl+space) and file (ctrl+space)
Am I missing a step?

Hello Rob,
Python advanced parser does not support code completion yet, however it's on our todo list for the next immediate release. We will start working on it shortly and happy to share results once this feature is implemented.
You might want to look at LSP-based Python parser instead, which supports code completion and some other semantic-based features.
Regards,
Andrew

Hi Andrew, I have 6.1 installed. When trying to run the C:\Users\Public\Documents\AlterNET Software\AlterNET Studio v.6\Demo\Editor.Lsp\QuickStarts\Parsers\PythonSyntaxParsing\ project I get a task cancelled exception. This is the same when running from the demo app and when compiling from source and running. This happens once Application.Run(new Form1()); completes. I can step through the constructor and Form1_Load without issue.
I have opened the Tasks debug window in VS and am unable to see any tasks listed while I step through. I am able to see the form while VS catches the exception.
System.AggregateException

Hi,
Could you please try to delete the following folder:
%USERPROFILE%\AppData\Local\Temp\Alternet.Lsp.Servers.Palantir.Pyls.Bundle
And try to run the demo again. You will have to wait while the sample starts for the first time, as it copies the Python distribution files to the temp directory.
