描述

Search before asking

  • I searched in the issues and found nothing similar.

Motivation

Using pulsar-shell interactively, it's kind of a pain to prefix everything withadmin. I think it would be nice if the command accepted admin and client on their own as special commands that put the command into that mode with an implicit prefix.

Solution

Allow admin and client, when passed on their own to enter into admin or client mode respectively, with the addition of one more command exitmode to return to the base state. These modes would not persist between sessions.

configname(hostname)> admin
configname(hostname) admin> help
Usage: pulsar-admin [options] [command] [command options]

研究方向
Start by examining the pulsar shell module in the Apache Pulsar repository, specifically the classes handling interactive shell commands. Look at how existing commands are registered and executed, likely in a class like InteractiveShell or ShellCommands. The feature requires adding 'admin' and 'client' as special commands that change the command prefix state, and an 'exitmode' command to reset. Check the prompt formatting logic to ensure the mode indicator is correctly displayed. There are no linked PRs or comments, so the implementation is open for design. Reference main files such as pulsar shell/src/main/java/org/apache/pulsar/shell/InteractiveShell.java or similar.
