How to send a request in chat view programmatically？

e. This feature may be a bit like show in memory inspactor with reference.
I checked the modules related to theia ai chat feature, but there seems to be no relevant implementation, and I didn't find any indirect way to do this.

Hi @lqd1434,

to submit a request in the chat programmatically, you can use the ChatService. Below at the example of creating a new session and submitting a new request from a command handler.

@injectable()
export class SampleCommandContribution implements CommandContribution {

    @inject(ChatService)
    protected readonly chatService: ChatService;

    registerCommands(commands: CommandRegistry): void {
        commands.registerCommand(SampleCommand, {
            execute: async () => {
                // creates a clean session
                const session = this.chatService.createSession(ChatAgentLocation.Panel, { focus: true });
                // submit a request
                await this.chatService.sendRequest(session.id, { text: 'Hello World!' });
            }
        });
    }
}

It is of course optional to create a new session first. You can also just submit a request in an existing session. You can obtain all existing sessions from the chat service (chatService.getSessions()).

You can then use this command in a context menu, see the documentation for more information.

@planger Thank you very much for your answer, I found the solution according to your answer, but I also found a problem:
why FrontendChatServiceImpl.createSession does not implements pinnedAgent arg ?

override createSession(location?: ChatAgentLocation, options?: SessionOptions): ChatSession {
        const session = super.createSession(location, options);
        session.model.onDidChange(event => {
            const changeSet = (event as { changeSet?: ChangeSet }).changeSet;
            if (event.kind === 'removeChangeSet') {
                this.changeSetFileService.closeDiffsForSession(session.id);
            } else if (changeSet) {
                this.changeSetFileService.closeDiffsForSession(session.id, changeSet.getElements().map(({ uri }) => uri));
            }
        });
        return session;
    }

Thanks for raising this issue! This is actually an oversight. I've opened a PR to fix this. #15070
