Updates and Uninstall

Tutorial: https://jeikcode.top/guide/updates.html

The desktop app, a browser opened from another machine, and a headless CLI all support multi-version updates and rollbacks. Windows, macOS, Linux, and HarmonyOS PC use the same commands. Prompts follow the JeikCode interface language (Simplified Chinese, English, and Vietnamese).

1. Desktop and WebUI

In the desktop app or the browser, use the update control at the top right. You can choose the stable or beta channel, read that version's notes, install a newer build, or switch to another version in the list.

When the update finishes, the page reloads onto the new version. A phone, another computer, or any other browser connected to the same service updates and rolls back the same way.

2. Command line

Run these commands on a headless server. No desktop window is required. Add -y to apply configuration changes without a prompt.

List published versions

jeikcode list
jeikcode list main
jeikcode list beta

list and list main show stable releases. list beta shows beta releases. The newest row is marked latest. The version you are running is marked current.

Move to a newer version

jeikcode up
jeikcode up main
jeikcode up main v7.2.4
jeikcode up beta
jeikcode up beta v7.2.4-beta.12
jeikcode upgrade --beta -y

up, update, and upgrade are the same command. With no channel, it installs the latest stable release. up main installs the latest stable release; a version after it installs that stable release. up beta installs the latest beta; a version after it installs that beta. --main and --beta also work after upgrade.

If the target is not newer than the running version, the command tells you to use down.

Install a specific or older version

jeikcode down main v7.2.3
jeikcode down beta v7.2.4-beta.8

down and downgrade are the same command. Both the channel and the version are required.

Return to the previous binary on disk

jeikcode rollback

This swaps the running program with the previous backup kept on disk. It does not download again. jeikcode up rollback does the same thing.

3. Uninstall

jeikcode uninstall
jeikcode uninstall simple
jeikcode uninstall all

• jeikcode uninstall walks through the removal and asks whether to keep user configuration. The program and its PATH entry are always removed.
• jeikcode uninstall simple removes only the program and its PATH entry, and keeps user configuration. It asks nothing, so scripts and agents can run it.
• jeikcode uninstall all removes the program, its PATH entry, and all user configuration. It asks nothing, so scripts and agents can run it.

User configuration lives in .jeikcode under the home directory (~/.jeikcode on Unix). When JEIKCODE_HOME is set, that directory is used instead. simple and all stop other running JeikCode processes before removing the program.
