Warn on Multiline Paste

Type Enhancement/Feature Request

What You Do

1. Copy a multiline string from somewhere, such as:

hello
world

1. Paste this into the terminal window

What You See

The pasted text is entered without a warning and immediately executed by the shell.

What You Expect

A popup dialog confirming that you really wanted a multi-line paste. In my experience, you usually don’t.

You would probably want a configuration option to enable/disable this for other people’s sanity’s sake.

Other Notes

This is different from the existing bracketed paste, because it (hopefully?) wouldn’t require shell integration to work.

I think I’ve found the location where you would implement this? https://github.com/Eugeny/terminus/blob/ceb75323fefa788d0cb7032df3d4cf0aee258722/terminus-terminal/src/api/baseTerminalTab.component.ts#L273. You would add a check here to see if “multiline pasting warning” was enabled, and if so, check the data variable for newlines and warn accordingly.

Now, we have the option multiLinePasteWarning which can be defined as false.

Could I humbly request that changes to user experience like this default to disabled, rather than changing default behaviour? Alternatively could/should the setting for disabling the warning be documented in the warning message?

Searching for ‘windows terminal newline warning’ brought up a number of irrelevant results unfortunately, and I couldn’t find it in the documentation. Thanks @diegosomar for mentioning the setting.
