Added a new terminal feature setting to control the feature, we check for spaces or back slashes and escape or wrap in double-quotes accordingly, the unit tests have been modified accordingly.

Hi @Tyriar ,

I've opened this PR but still need some clarity on a few aspects regarding smart paste:

Relative Paths: Should we support relative paths? If so, to what extent? Considering they can start with . or .., what should be the scope for these?

Shell Type Check: Do we really need to check for shell types? Would it be simpler to just wrap any path in quotes if it contains spaces or backslashes, regardless of the shell?

PowerShell Behavior: I've noticed that in a PowerShell terminal, the _paste function in terminal.clipboard.contribution.ts doesn't seem to trigger when pasting. However, the middle mouse click works fine. Is this something we should address as a bug?

Smart Paste behavior: Should smart paste only come into action if the entire clipboard string is a path? Or should we also consider parts of the string that might be paths and wrap or escape those?

Thank you for your help with these questions! 😊

Thank you for your help with these questions! 😊

@Tyriar while I go through your comments and incorporate them, could you please check these queries? 🙂

[Tyriar]

@Parasaran-Python

Relative Paths: Should we support relative paths? If so, to what extent? Considering they can start with . or .., what should be the scope for these?

You could experiment with using detectLinks from terminalLinkParsing.ts which does relative paths and so much more. Maybe just calling into that and handling when IParsedLink.path matches the entire text? ie. no suffix or prefix

Shell Type Check: Do we really need to check for shell types? Would it be simpler to just wrap any path in quotes if it contains spaces or backslashes, regardless of the shell?

We could have a default path, and then tweak for shell-specific behavior as necessary.

PowerShell Behavior: I've noticed that in a PowerShell terminal, the _paste function in terminal.clipboard.contribution.ts doesn't seem to trigger when pasting. However, the middle mouse click works fine. Is this something we should address as a bug?

Pasting in PowerShell is actually handled a little specially, there's a custom keybinding which sends ^V to PSReadLine which then handles the pasting.

https://github.com/microsoft/vscode/blob/8b7a797a5ad84794930646cd192c9dc33be32fbb/src/vs/workbench/contrib/terminal/browser/terminal.contribution.ts#L141-L150

As you see in the comment this is done to properly support multi-line pasting. Not sure the best way to handle this, maybe we should only be doing that when the string is multi-line? 🤔

Smart Paste behavior: Should smart paste only come into action if the entire clipboard string is a path? Or should we also consider parts of the string that might be paths and wrap or escape those?

I think it makes the most sense only if the entire text is a path. Otherwise it would be pretty unexpected imo.

[Tyriar]

@Parasaran-Python fyi it's a little easier to review your change if you don't force push. Force pushing breaks diffs so I can't diff when you've newly done over what you did that i already reviewed

[Parasaran-Python]

Sure @Tyriar will not force push going forward, force push had become necessary as I prefer rebase over merge to have a clean linear commit history,

Fyi, have incorporated the changes, just the relative paths thing is pending.

[Parasaran-Python]

@Tyriar , I experimented with detectLinks and noticed an issue: it ignores anything after a space in paths that contain spaces. A relative path could be mistaken for another keyword. For example, if I have a folder named "cd dir" in my current working directory, and I try to paste "cd dir" in the terminal to access the folder "dir," the command gets wrapped in quotes. This leads to unintended behavior.

If it was just for cd we could even check if the path string exists (on device) before wrapping but this could be used with a command like mkdir as well.

I hope I was clear.

Need some clarity in this aspect, as I seem to be approaching a dead end 😕

May be the scope has to be limited to a safe extent (for relative paths).

[Tyriar]

Yeah you're right, I thought it handled space paths too but that's tackled here:

https://github.com/microsoft/vscode/blob/6c8fa5593aefac8f42e2e4f48f7b344a588ecb65/src/vs/workbench/contrib/terminalContrib/links/browser/terminalLocalLinkDetector.ts#L37-L59

Perhaps use terminalLinkParsing first and then fallback to the simpler matching?

[Parasaran-Python]

Thanks @Tyriar that works, the only thing that's pending now is the ctrl+v on powershell,

smart paste not working on ctrl+v on PS might be a pain, I would love to have smart paste working even with a ctrl+v action on a power shell instance 🙂

While I explore ways to achieve this please do drop suggestions if any.😊

Thanks again.

[Parasaran-Python]

@Tyriar have made some changes, requesting you to re-review.

[Parasaran-Python]

Hello @Tyriar , I see this PR is getting spammed, can we bring this PR to closure as soon as possible? 🙂 Thanks.

[Parasaran-Python]

@Tyriar could you please take a look at this when you have a moment 🙂?

[Parasaran-Python]

@Tyriar following up for a review 🙂

[Parasaran-Python]

Greetings @Tyriar , is there something missing in this PR due to which it has been kept on hold?🙂

[Parasaran-Python]

Hello @Tyriar could you please go through my PR and let me know if there are some changes expected 🙂
