[Feature]: Save terminal scrollback output into text file

[nyirog130]

Feature description

Would be very good if we can save all scrollback logs into a file, with a single command or option

Implementation Suggestion

Maybe an option for that in the context menu, and/or a wsh command could do that

Anything else?

No response

I think it's a good enhancement and I would like to try implementing it :)

The way I thought that might be working is:

# output scrollback of current terminal
wsh termtext

# Save to file
wsh termtext > terminal.log

# output scrollback of specific block
# is it useful? but it seems not hard to implement
wsh termtext -b term:abc123

That is good! Please also add mouse option for that, like right click -> save scrollback, or an option in the context menu

Hmm, I encountered an issue when implementing for ssh.

Implementing this command locally is straightforward and easy. We just need TermGetScrollbackLinesCommand to capture the frontend. I've already done and tested ok.

But remote SSH connections are tricky, because the terminal data lives in the browser's xterm.js buffer, not on the server. When running over SSH, the cmd routes back to the local machine's frontend, which tries to read the local browser buffer - but the remote terminal's data isn't there. To make this work over SSH, we might need to implement terminal output buffering on the server side.

Just merged #2892 #2892 which should implement this. We have a new context menu item to save to a file (with a system dialog) and then wsh termscrollback that implements saving as well. Should ship with the next patch release

fixed in v0.14.2
