Yazelix Nova docs
01
Start with Yazelix Nova
Try or install Stable, then choose the Nova Rio or current-terminal entrypoint.Yazelix Nova is a Nix-packaged terminal workspace. You need Nix with flakes enabled. This guide describes the audited Stable revision shown in the site footer. Main and Edge may carry later behavior.
Choose a channel
Section titled “Choose a channel”| Channel | Install reference | Use |
|---|---|---|
| Stable | github:Yazelix/nova/stable |
Checked and dogfooded release |
| Main | github:Yazelix/nova/main#yazelix-main |
Frequent accepted updates |
| Edge | github:Yazelix/nova/edge#yazelix-edge |
Experimental dogfooding |
Immutable nova-v* tags select exact releases. A Nix lock file keeps its
selected revision until you update it.
Install
Section titled “Install”nix profile add --refresh github:Yazelix/nova/stableOpen the desktop workspace through Nova Rio:
yzx launchStart the same managed workspace in the current terminal or over SSH:
yzx enterDay-to-day use
Section titled “Day-to-day use”Set a terminal profile to run yzx enter, or open the installed Linux desktop
entry. Most days, you do not type another yzx command after Nova opens.
Alt Shift K opens Ratconfig; the keybinding map covers the
rest of the workspace.
Try without installing
Section titled “Try without installing”nix run github:Yazelix/nova/stable -- launchnix run github:Yazelix/nova/stable -- enterRun the owned preflight without opening Rio or Zellij:
nix run github:Yazelix/nova/stable -- doctorNamed sessions
Section titled “Named sessions”Plain yzx launch and yzx enter start independent sessions. Add
--session NAME to create a fresh named session:
yzx enter --session projectyzx launch --session projectAttach to a live session by its full name:
yzx enter attach projectyzx launch attach projectCreation fails for a live name; attachment fails for a missing name.
Inside Nova, press Ctrl Alt o, then w to open the session manager. Select a
live session to switch, or type a missing name and press Enter with the
Yazelix layout selected to create it.
After you switch sessions, popups or Alt h / Alt l may pause for several
seconds. Press Alt 1-9 to select a tab, then retry. See
Workspace keys for the session-manager chord.
Choose a package
Section titled “Choose a package”Package names follow yazelix[-no-rio][-no-helix][-no-yazi]:
| Package | Rio | Managed Helix | Managed Yazi |

nix profile add --refresh github:Yazelix/nova/stable#yazelix-no-helixThe four no-rio packages retain yzx enter; yzx launch reports that Rio is
unavailable. Helix-free packages need an installed editor selected through
editor.command. Yazi-free packages need matching host yazi and ya
commands.
See the repository installation and package reference for platform evidence, Home Manager declarations, and binary-cache details.

02
Configure Yazelix Nova
Use Ratconfig, sparse semantic overrides, or owner-native files.Standalone pageInside Nova, press Alt Shift K to open Ratconfig. From another terminal, run:
yzx configRatconfig shows packaged defaults, saves explicit overrides, and marks Home Manager-owned files as read-only.
Main settings
Section titled “Main settings”The optional root config is:
~/.config/yazelix/config.tomlNova does not create this file until you save a root setting. Missing keys inherit packaged defaults. Unsupported or misspelled paths fail validation.
Common fields include:
| Field | Default | Applies to |
|---|---|---|
appearance.mode |
dark |
Managed component appearance |
appearance.straight_border_style |
single |
New sessions |
shell.program |
nu |
New panes |
shell.atuin |
true |
New managed shells |
editor.command |
yzx-hx |
New editor opens |
forest.enabled |
true |
New managed Helix editors |
forest.side |
right |
New managed Helix editors |
sidebar.command |
radar |
New sessions |
sidebar.args |
[] |
New sessions with a custom sidebar command |
welcome.enabled |

New agent popups |
keybindings.sidebar |
Alt Shift H |
New sessions |
keybindings.sidebar_focus |
Ctrl y |
New managed Helix editors |
bar.widgets |
Nova widget list | New launches |
For example:
[appearance]mode = "light"
[shell]program = "fish"
[editor]command = "nvim"Ratconfig labels each field with its apply timing. Start a new session for
fields marked next launch or next session.
Straight borders may be single or double. Zellij’s native rounded corners
take precedence when enabled. Set forest.enabled = false to start managed
Helix without Nova configuring or opening Forest.
Radar is the default sidebar. Set sidebar.command = "yzx-yazi" to use Nova’s
managed Yazi there, or select another executable and pass its arguments through
sidebar.args. Custom sidebar commands do not receive Radar-specific keys,
permissions, onboarding, or diagnostics.
Native files
Section titled “Native files”Component-specific configuration lives beside config.toml:
| Surface | Path |
|---|---|
| Nova Rio configuration | ~/.config/yazelix/rio/config.toml |
| Guarded Zellij scalars | ~/.config/yazelix/zellij/config.kdl |
| Extra Zellij plugins | ~/.config/yazelix/zellij/plugins.kdl |
| Starship overrides | ~/.config/yazelix/starship.toml |
| Nushell additions | ~/.config/yazelix/nu/env.nu, nu/config.nu |
| Helix overrides | ~/.config/yazelix/helix/ |
| Yazi config and assets | ~/.config/yazelix/yazi/ |
Ratconfig exposes exact file actions for these surfaces. Native owners keep their own validation and schema.
Home Manager
Section titled “Home Manager”The Home Manager module owns one enable flag, package selection, sparse
programs.yazelix.config.settings, and optional native files. It writes no
runtime config unless you declare one of those options.
Store-backed files appear as read-only in yzx config. Edit the named
programs.yazelix.config.* option, then run your normal Home Manager switch.
Generated state
Section titled “Generated state”Nova writes generated runtime state to
${XDG_DATA_HOME:-$HOME/.local/share}/yazelix unless YAZELIX_STATE_DIR
overrides it. Edit the config inputs, not generated output.
See the repository configuration reference for the complete field and native-file contracts.
03
Yazelix Nova Keybindings
The packaged workspace key grid and its supported customization surface.Standalone pageNova extends the Helix and Vim h/j/k/l model across the workspace.
Movement grid
Section titled “Movement grid”| Layer | h |
j |
k |
l |
|---|---|---|---|---|
Alt |
Focus left or previous tab | Focus down | Focus up | Focus right or next tab |
Ctrl Alt |
Move tab left | Move pane down circularly | Move pane up circularly | Move tab right |
Alt Shift |
Sidebar | Git popup | Config popup | Agent popup |
Workspace keys
Section titled “Workspace keys”| Key | Action |
|---|---|
Alt Shift M |
Toggle the command menu |
Alt Shift A |
Show a random visual with Anima |
Alt Shift H |
Toggle the configured sidebar; Radar is the default |
Alt Shift Y |
Toggle the full managed Yazi popup |
Ctrl y |
Toggle focus between Forest and managed Helix |
Alt Shift T |
Open a new workspace tab |
Alt Shift W |
Close the active workspace tab |
Ctrl Alt t |
Toggle Zellij tab mode |
Alt Shift F |
Toggle the focused pane fullscreen |
Alt 1-9 |
Go to tab 1-9 |
Alt m |
Open a new pane |
Alt j / Alt k |
Focus the next / previous work pane, wrapping within the stack |
Ctrl q |
Quit the Nova session |
Ctrl Alt o |
Open Zellij session mode; press w for the session manager |
Alt r |
Reveal from the editor or return from Yazi |
Alt z |
Retarget the tab workspace from Yazi with zoxide |
Press a popup key again to hide or close that surface and return to the tiled workspace.
Every new tab starts with a focused quick zoxide search. Enter opens the
selected directory; Tab switches to full Yazi. Tab in startup Yazi returns
to quick search at the directory you reached.
Customize keys
Section titled “Customize keys”Open yzx config to edit the managed config, agent, Git, menu, screen, sidebar,
and sidebar-focus chords. The corresponding keybindings.* fields live in
~/.config/yazelix/config.toml and accept a key chord or false. Changes apply
to new sessions.
The fixed Alt Shift Y, application-local Alt r, and Yazi Alt z bindings
remain in their native packaged owners. Nova rejects collisions among managed
semantic keys.
Ratconfig’s Keys tab is the complete packaged reference. The runtime sources
are defaults/zellij/config.kdl, the managed Helix config, and the managed Yazi
keymap.
04
Update Yazelix Nova
Update the Nix profile or declarative input that owns the installed package.Standalone pageChoose one update owner for each Yazelix install.
Profile installs
Section titled “Profile installs”Confirm the installed profile entry when needed:
nix profile listUpgrade the profile-owned package:
nix profile upgrade --refresh yazelixPass the exact installed package name when your profile uses another entry name.
Home Manager installs
Section titled “Home Manager installs”Run this from the configuration that declares the Yazelix input:
nix flake update yazelixReplace yazelix with your input name, then run the configuration’s normal
Home Manager or nix-darwin switch command. Do not use nix profile upgrade for
a package installed by Home Manager.
Channels
Section titled “Channels”The update follows the input’s stable, main, edge, or immutable tag
reference. Stable is the normal release channel. Main receives accepted updates
more often, and Edge carries experimental dogfood changes.
Live windows
Section titled “Live windows”The updated package applies to future launches. Open Nova sessions keep their current immutable Nix store paths until you close and relaunch them.
See the repository installation reference for package-owner details.
05
Recover a Nova Launch
Use the supported preflight, status, config, and package-owner checks.Standalone pageStart with doctor:
yzx doctoryzx doctor validates Nova’s owned config, helpers, selected editor, Yazi pair,
Zellij package, layout, and plugins. A failed preflight prints the failing
check without opening Rio or Zellij. Doctor and status inspect without creating
or repairing configuration, runtime files, Rio state, or plugin permissions.
Existing launch and run commands prepare missing runtime state.
Inspect runtime ownership
Section titled “Inspect runtime ownership”yzx statusyzx status --jsonyzx --versionStatus reports the selected package, config home, state directory, shell, editor, popup keys, layout, Yazi source, and session context.
Set up Radar activity
Section titled “Set up Radar activity”yzx radar-setupRadar checks Codex, Claude Code, and OpenCode in order, reports existing integrations, skips unavailable agents, and asks before changing each supported agent. Start a fresh agent session after setup and review any agent-owned trust step it reports.
Check the root config
Section titled “Check the root config”The root config is optional:
~/.config/yazelix/config.tomlOpen yzx config to inspect known invalid fields and exact native-file actions.
Back up config.toml before manual recovery. Removing an optional override
restores its packaged default on the next applicable launch.
Clean up old manual installs
Section titled “Clean up old manual installs”If an old clone, wrapper, or shell function shadows the current package:
type yzxcommand -v yzxThe command should resolve to the Nix profile or Home Manager package that owns the install. Remove a stale wrapper only after you identify its owner.
Stale flake cache
Section titled “Stale flake cache”For a profile install:
nix profile upgrade --refresh yazelixHome Manager users update the declared input and run their normal switch.
Treat Classic residue as a warning
Section titled “Treat Classic residue as a warning”Doctor reports recognized Classic state and migration backups in the active roots. Nova does not load, archive, or remove those paths. External scripts may still reference them.
Start a fresh session
Section titled “Start a fresh session”yzx enterUse a new session when the updated package or a next-session setting needs to take effect. Zellij owns existing session lifetime and attachment.
Do not repair Nova by editing generated files under ~/.local/share/yazelix.
Fix the owned config input or package owner instead.
06
Nova Runtime Model
The yzx entrypoints, package variants, config boundary, and component owners.Standalone pageYazelix Nova is a Nix-packaged terminal workspace with one front door: yzx.
yzx launch -> Nova Rio -> managed Zellij workspaceyzx enter -> current terminal -> managed Zellij workspaceyzx run -> prepared Nova environment -> requested programyzx-zellij -> Nova's exact packaged Zellij CLIBare yzx prints help. launch is the only Nova Rio route. enter needs an
interactive terminal and works without a display server.
Packages
Section titled “Packages”The full package includes:
- Nova Rio for graphical launch
- the Yazelix Zellij fork and managed layout
- managed Yazi, Helix, and Nushell
- popup, config, screen, tutor, Git, prompt, and completion tools
Package names follow yazelix[-no-rio][-no-helix][-no-yazi]. Each suffix
removes that managed package while retaining the remaining integration.
Rio-free packages retain yzx enter; Helix-free and Yazi-free packages use the
selected host tools.
Generated runtime state
Section titled “Generated runtime state”Nova renders runtime state under:
~/.local/share/yazelixThis directory is output. Edit the config inputs instead.
User config
Section titled “User config”The optional sparse semantic config is:
~/.config/yazelix/config.tomlComponent-native files live under the same ~/.config/yazelix/ root. Normal
host config at ~/.config/{helix,yazi,starship} is not loaded by default.
Workspace identity
Section titled “Workspace identity”Nova targets managed panes by identity:
- Forest is the managed Helix file tree
- Radar is the default configurable sidebar;
yzx-yaziis an optional replacement - each new tab starts with a focused quick zoxide search;
Tabswitches to startup Yazi - each tab has one canonical workspace root
- managed opens reuse the tab’s editor
yzx revealopens the persistent Yazi popup at a target- Git and agent tools use workspace-scoped popups
Alt zretargets the tab workspace and editor together
Ownership
Section titled “Ownership”Nova Rio owns graphical launch. Zellij owns multiplexing. Forest owns the managed Helix tree, Radar owns activity presentation, and Nova Bar owns top-bar tabs, modes, and status. Focused first-party packages own popups, pane orchestration, screens, and Yazi themes. Nova pins and composes their package outputs. Nova and Zellij lists the packaged layout, plugins, and the Nova Zellij fork delta.
See the repository architecture for component contracts and verification gaps.
07
Nova and Zellij
What Zellij owns, what Yazelix packages around it, and what the Nova Zellij fork changes.Standalone pageNova uses Zellij 0.46 as the multiplexer. Tabs, stacked panes, floating panes, layouts, and the plugin API are Zellij. Yazelix ships a default layout, keys, plugins, and yzx around that. The Nova Zellij fork keeps the pinned upstream Zellij base and adds the runtime seams listed here.
Zellij
Section titled “Zellij”Upstream Zellij owns multiplexing: tabs, tiled and stacked panes, floating panes, sessions, layouts, and plugins. Rounded pane corners, pane frames, and swap layouts are Zellij settings. Nova’s default workspace uses those surfaces.
Yazelix around Zellij
Section titled “Yazelix around Zellij”The product shape around the multiplexer lives in packages, layout, and plugins:
| Piece | Owns |
|---|---|
| Packaged layout and keys | Radar-default sidebar, quick zoxide search before startup Yazi, stacked work panes, wrapping work-pane focus and movement, popup chords |
| Zellij Pane Orchestrator | Tab-local workspace roots, focus, sidebar, editor, and popup routing |
| Zellij Popup | Git, agent, Ratconfig, Yazi, and other floating TUIs |
| Yazelix Radar | Sidebar session, pane, command, and agent-activity presentation |
| Nova Bar | Top bar tabs, modes, session details, and status widgets |
yzx and Ratconfig |
Launch, enter, read-only diagnostics, and live config |
Ratconfig can change a Zellij setting while a session runs. The popup is Yazelix. The value it writes, such as rounded corners, is still Zellij.
Nova Zellij fork
Section titled “Nova Zellij fork”Nova Zellij starts from upstream Zellij 0.46 and uses its native Kitty direct-placement path. The fork retains focused fixes for Yazi image correctness alongside the runtime seams below.
Upstream’s explicit_theme_hue and native theme actions own startup appearance.
The remaining Yazelix delta is deliberately narrow:
| Delta | Role |
|---|---|
| Three-island status hints | The native status bar groups mode actions by their real modifiers, so Ctrl-Alt stays distinct from Ctrl and Alt |
| Isolated plugin permission cache | yzx can pre-grant packaged plugins, including Radar, without touching standalone Zellij’s global cache |
| Sixel replacement cleanup | Covered and erased rasters are retired without reusing a live image ID |
| Kitty crop and resize correctness | Distinct source crops keep their pixels, and cell-size changes rebuild scaled rasters |
| Bounded Unix session probes | An unresponsive session socket cannot block session listing indefinitely |
| Named tiled-layout selection | Plugins can select an exact tiled layout without hiding or refocusing floating panes |
| Straight border style | Nova can select single or double straight pane borders; native rounded corners take precedence |
| Stable stacked-pane identity | Stack order survives focus, close, and the sidebar swap layout |
| Replacement-client plugin cleanup | A replacement client gets a fresh ID, disconnected plugin instances retire, and a new background subscription receives its own initial pane and tab state. The fork carries this from upstream pull request 5272 |
Three-island hints change Zellij’s native status bar. Nova Bar is a separate plugin for the top bar. Image-preview coverage, removal conditions, and the pinned upstream base live in the Nova Zellij fork notes.

Nova Customization Surfaces
Choose the semantic root config, an owner-native file, or Home Manager.Standalone pageStart with yzx config. It displays packaged defaults and writes sparse
overrides to ~/.config/yazelix/config.toml.
Main settings
Section titled “Main settings”Use it for:
- appearance mode
- shell, Atuin history, and editor commands
- welcome behavior
- managed popup and sidebar keys
- agent command and arguments
- popup margins and top-bar widgets
Native sidecars
Section titled “Native sidecars”Use sidecars for tool-specific preferences that Yazelix does not render:
| Surface | Path |
|---|---|
| Nova Rio configuration | ~/.config/yazelix/rio/config.toml |
| Zellij scalar sidecar | ~/.config/yazelix/zellij/config.kdl |
| Extra Zellij plugins | ~/.config/yazelix/zellij/plugins.kdl |
| Starship overrides | ~/.config/yazelix/starship.toml |
| Nushell additions | ~/.config/yazelix/nu/ |
| Yazi config and assets | ~/.config/yazelix/yazi/ |
| Helix config, languages, and Steel files | ~/.config/yazelix/helix/ |
Home Manager
Section titled “Home Manager”Home Manager exposes programs.yazelix.enable, package selection, sparse
settings, and optional native files. Store-backed files remain read-only in
Ratconfig. Change the reported module option and run the normal switch.
Generated state
Section titled “Generated state”Files under ${XDG_DATA_HOME:-$HOME/.local/share}/yazelix are generated output.
Change the config input or package owner instead of editing runtime state.
See the repository configuration reference for file layering and validation details.

Nova Troubleshooting Checklist
Check the owned runtime, package source, config input, and generated-state boundary.Standalone page1. Run doctor
Section titled “1. Run doctor”yzx doctor2. Check command ownership
Section titled “2. Check command ownership”type yzxcommand -v yzxThe command should resolve to your Nix profile or Home Manager owner path, not an old ~/.local/bin/yzx wrapper or shell function.
3. Refresh stale flake evaluation
Section titled “3. Refresh stale flake evaluation”nix profile upgrade --refresh yazelixHome Manager users update their declared input and run the normal switch.
4. Inspect config
Section titled “4. Inspect config”yzx configThe optional root file is ~/.config/yazelix/config.toml. Back it up before
manual recovery. Ratconfig exposes invalid fields and exact native-file actions.
5. Keep generated state generated
Section titled “5. Keep generated state generated”Do not manually edit:
~/.local/share/yazelixRelaunch Nova after fixing the owning input. Open sessions keep their existing package and next-session settings.
6. Report precise failures
Section titled “6. Report precise failures”Useful issue details:
- OS and architecture
- install owner: Nix profile, Home Manager, or one-off
