Missing source information causing "identical line collapsing" in VsCode Debug Console

Hello everyone,

TLDR: “Ominisharp console output” is not providing “Source Information” to VsCode https://github.com/microsoft/vscode/issues/141218

Description (using browser)

Yesterday we noticed that when debugging inside VsCode some code that tried to write to StdOut, these lines could be collapsed. This is the same things that you could see on Chromium-based browser. Remember for later that the first example is not grouping while the second one is.

This can also be tempered with:

In VsCode

Javascript:

C# / F#:

Settings ?

We opened an issue on VsCode and we were hinted at:

issue is … we did not knew or set it, meaning we were running with the default value all along and still have 2 different output on the same settings which lead us here:

If console output provides source information (in the following screenshot on the right hand side), then lines are only collapsed if their source is identical. @isidorn is this correct? The following example shows that identical lines are collapsed in Node.js for the loop but not for individual console.log statements:

If a debug extension does not provide source information, then identical are always collapsed. This seems to be the case for C# and F#.

I think we (VS Code) should consider not to collapse lines if there is no source info available.

@gregg-miskelly your opinion?

fine for me l, just double checking
