Issue Description

I am experiencing a problem with... filename showing up in Console window on F5/CTRL+F5

preview problem1

While when there is some content output it will be removed when it's done, when there's no content (such as the .ps1 file has only function definition) it will look like on attached gif.

Similar situation is here:

On production PowerShell:

PrzemyslawKlys commented 5 years ago

This actually has a huge side effect.

Notice how this function uses scriptblock { } as a parameter and and then when uusing F5 or CTRL+F5 it takes whatever is displayed in the Terminal into tha script block (which in this case is file name). Only if use F6 (which in my case is Run Current File) it behaves as expected.

preview problem2

This makes it quite hard to work with.

SydneyhSmith commented 5 years ago

Sorry for a bit of a delayed response but I am having trouble fully understanding what is happening here. Would you mind re-phrasing what the expected behavior is and what the current behavior is. Thanks as always!

PrzemyslawKlys commented 5 years ago

What you're seeing here is few things:

when the script has defined a function and only that and you press F5 vscode will display filepath to Terminal

And it will stay like that.

when the script is run with F5 or CTRL+F5 PowerShell doesn't show it's running in a left bottom corner
when the script is run and you use a script block your output in the terminal will get mixed up with file path of an executed script
when the script is run it will sometimes display WARNING and other streams in weird places (like on the screenshot 2 posts up.

ili101 commented 5 years ago

Let me try to explain this more simply. This happens when "powershell.developer.featureFlags": [ "PSReadLine" ] is enabled. If you run your saved script (with F5 for example), the script path will be written to the console (as before). the only difference is that it's not adding a "line break" after writing the path.

it's not cussing any "coding problem" but a "display" one. if your code don't have any output, after the code run you will be left with your text cursor on the start of the path line so if you write something you are writhing it on the path text overwriting it. or if your code have output it will do the same thing and write it's first output line on the path line so if the output is shorter then the path you will get a line with a mix of the two strings displayed.

So the solution is just to make it line break/move to the next line after writing the path. Exactly as on a regular Powershell windows you will writhe the file path and hit enter and as a result the text cursor moves down and only then the file output starts from there.

SydneyhSmith commented 5 years ago

It looks like start without debugging needs to add a new line either after writing the file path or before output is written, thanks for reporting this!

PrzemyslawKlys commented 5 years ago

Just FYI. It's still not working correctly in 2.0.1

ili101 commented 5 years ago

Can also confirm that it is still a problem. What is the point of releasing preview 2 to us if the bugs we reported on preview 1 are not addressed?

TylerLeonhardt commented 5 years ago

@ili101 preview.2 mostly contained work on the debugger. Sadly we couldn't get to everything this time around.
