How to attach a frontend terminal to a backend terminal process?

PeimingMo1 · 23 October 2020 03:16

I have created a terminal process in the backend, and used ProcessManager to access to it, and have passed the terminal id to the frontend:

However, in frontend, i don’t know how to open a terminal and acttach to this terminal process.

I have used let term = TerminalFrontendContribution.getById(terminalId) and TerminalFrontendContribution.activateTerminal(term) to try, but it didn’t work.

Please help, thank you very much.

@PeimingMo1 you can likely use the TerminalService implemented by the TerminalFrontendContribution.
You’ll have access to methods such as:

Among others. If you’d like to learn how to attach to a terminal a simple search for attach in the extension should suffice:

/**
 * Create a new shell terminal in the back-end and attach it to a
 * new terminal widget.
 * If id is provided attach to the terminal for this id.
 */
async start(id?: number): Promise<number> {
    this._terminalId = typeof id !== 'number' ? await this.createTerminal() : await this.attachTerminal(id);
    this.resizeTerminalProcess();
    this.connectTerminalProcess();
    if (IBaseTerminalServer.validateId(this.terminalId)) {
        this.onDidOpenEmitter.fire(undefined);
        return this.terminalId;
    }
    this.onDidOpenFailureEmitter.fire(undefined);
    throw new Error('Failed to start terminal' + (id ? ` for id: ${id}.` : '.'));
}

Yes, function start works. Thank you.
