Zellij FAQ
How do Zellij's floating panes differ from its tiled panes in terms of functionality and persistence?
Floating panes in Zellij are first-class citizens that can be toggled on and off, moved, resized, and pinned to stay always-on-top. They are persistent, meaning commands running within them continue in the background even when hidden. Tiled panes can also be converted into floating panes and vice versa.
What capabilities do Zellij layouts offer for automating development workflows and managing configurations?
Zellij layouts, defined in KDL files, allow users to automate workflows by describing entire development environments, including panes, tabs, terminals, commands, and plugins. They support pre-configuring commands, automatically opening files in an editor, defining reusable pane templates, and structuring multiple tabs for different purposes. Layouts can be version-controlled and shared for seamless onboarding.
How does Zellij's session management system, including Session Resurrection, help users maintain context across tasks and reboots?
Zellij's session management provides a quick way to switch between running sessions, create named sessions, and manage them in the background. Session Resurrection is a unique feature that allows users to bring back closed sessions with their full pane structure and commands, even after reboots, preserving complex task contexts.
What are the primary advantages of using Zellij's built-in web client for accessing terminal sessions?
The web client enables access to Zellij sessions from any web browser without requiring a terminal emulator. It includes built-in authentication, allows persistent sessions to be bookmarked via URL, and facilitates seamless switching between terminal and browser. This feature is ideal for pair programming, remote access, and sharing sessions with teammates.
Which programming languages can be used to develop plugins for Zellij, and what kind of access do these plugins have?
Plugins for Zellij can be developed in any language that compiles to WebAssembly, with Rust having first-class support and a dedicated SDK. These plugins have access to Zellij's state and events, can render custom user interfaces, respond to user input, and are distributed as single .wasm files that do not require installation.
How do 'Command Panes' in Zellij enhance the management and execution of commands compared to standard terminal output?
Command panes treat commands as first-class citizens, allowing users to see exit codes, re-run commands with a single key press, and start commands in a suspended state to be run on-demand. They can be included in layouts with the
start_suspended option, making them perfect for managing build commands, tests, or development servers that don't need to run immediately.Source: zellij.dev
