Paste Mode commad

[mrrezaie]

Feature or enhancement

Proposal:

Hi, the new Paste Mode feature is actually amazing, and I no longer need to install ipython console. However, the F3 key seems to be the only way to activate it. I was wondering if there is a special command to trigger the paste mode rather than a keyboard key.
I'm trying to do this in a simple extension in vscode that sends the selected text to the console, and I want to activate the paste mode, send the code, and execute. This would be much faster.

Looking forward to hearing from you.

Thank you in advance.

Has this already been discussed elsewhere?

Can you simulate a key-press in a Visual Studio extension? That would be the most compatible, and would require no upstream changes.

@mrrezaie About AA-Turner's idea:

it depends on where the REPL is
maybe not: microsoft/vscode#104832
maybe yes: PseudoTerminal exposes a handleInput method https://code.visualstudio.com/api/references/vscode-api

let us know if you found a solution!

these might work

await vscode.commands.executeCommand('workbench.action.terminal.sendSequence', {
  text: '\u0003' // Ctrl+C (SIGINT)
});
const term = vscode.window.createTerminal('My Term');
term.show();
term.sendText('\x1b[A', false);    // Up arrow, use '\x1bOR' for F3

Thanks both, I had tried that, but sendText failed:

>>> \x1bOR
  File "<python-input-0>", line 1
    \x1bOR
     ^
SyntaxError: unexpected character after line continuation character

Also, the F3 keyboard shortcut actually doesn't trigger the paste mode in vscode terminal. A built-in python command is needed.

Thanks again.

I have installed the extension benmcmorran.vscode-api-explorer

Then I opened two terminals: in one I had python.exe from the main branch running; in the other I started the extension

When I typed vscode.window.terminals[0].sendText('\x1bOR', false) in the terminal provided by the extension, this started the python paste mode.

I think that here you have a Terminal issue rather than a python issue. You don't need a modification in cpython.
I would suggest to investigate more in the characteristics of your terminal - on Linux a command like showkey -a or cat -v should show you the most adequate escape sequences (when you press the keys you are interested in).

I would say that this issue should be closed - it's not a python REPL limitation that we are speaking about!

It is working perfectly now, I don't know why this didn't work previously, Thanks a lot @nilleb and @AA-Turner
