# zellij
This plugin provides aliases, functions, and completions for [zellij](https://zellij.dev/),
the terminal workspace (multiplexer). To use it, add `zellij` to the plugins array in your
zshrc file.
```zsh
plugins=(... zellij)
```
## Dynamic prefix
The default prefix is `zj`. To use the shorter `z` prefix instead, set the following variable
before oh-my-zsh is sourced:
```zsh
ZSH_ZELLIJ_PREFIX_Z=true
```
When `ZSH_ZELLIJ_PREFIX_Z` is set, the root alias (`z`) and sub-command prefix are handled
separately:
- If `z` is **not** taken → `z`=zellij, sub-commands use `z` prefix (`zl`, `za`, …)
- If `z` **is** taken (e.g., by zoxide) → `zj`=zellij, but sub-commands still use `z` prefix (`zl`, `za`, …)
This means only the root alias falls back to `zj`; the shorter sub-command shortcuts remain
usable.
All aliases and functions perform a conflict check before being defined — if a name is already
taken by another alias, function, or command, it is silently skipped.
## Aliases
| Alias (default) | Alias (with `z`) | Alias (`z` + conflict) | Command | Description |
| ---------------- | ---------------- | ---------------------- | ---------------------------- | ------------------------ |
| `zj` | `z` | `zj` | `zellij` | Zellij command |
| `zjl` | `zl` | `zl` | `zellij list-sessions` | List sessions |
| `zjs` | `zs` | `zs` | `zellij -s` | Start a named session |
| `zjda` | `zda` | `zda` | `zellij delete-all-sessions` | Delete all sessions |
| `zjka` | `zka` | `zka` | `zellij kill-all-sessions` | Kill all sessions |
| `zjr` | — | — | `zellij run` | Run a command in a pane |
## Functions
| Function (default) | Function (with `z`) | Command | Description |
| ------------------- | ------------------- | ------------------------ | -------------------- |
| `zja` | `za` | `zellij attach` | Attach to a session |
| `zjd` | `zd` | `zellij delete-session` | Delete a session |
| `zjk` | `zk` | `zellij kill-session` | Kill a session |
The following convenience functions are always available (unless the name is already taken):
| Function | Command | Description |
| -------- | ---------------------------- | ---------------------------------- |
| `zr` | `zellij run --` | Run a command in a pane |
| `zrf` | `zellij run --floating --` | Run a command in a floating pane |
| `ze` | `zellij edit` | Edit a file in a pane |
## Completions
This plugin caches the zellij completion script. On first load the cache is generated
synchronously; subsequent updates (when the `zellij` binary is newer than the cache) happen in
the background.
Session-aware completions are provided for `attach`, `delete-session`, and `kill-session`
functions — only relevant sessions (all, running, or exited) are offered.
