# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## What this is

A [Quickshell](https://quickshell.org/) configuration — a QML-based Wayland desktop shell (bar, launcher, tray, decorations) for a Hyprland/wlroots setup. `~/.config/quickshell` is a symlink to this repo, so Quickshell loads `shell.qml` here as the "default" config.

## Running / testing changes

```sh
qs                 # runs ~/.config/quickshell/shell.qml (this repo, since it's the symlinked default config)
qs -p .            # run this directory explicitly regardless of symlink
qs -n              # exit immediately if another instance is already running (use to avoid duplicate shells while iterating)
```

Quickshell hot-reloads QML on file save when already running, so for most edits just save and check the running instance rather than restarting `qs`. It watches file CONTENT: `touch` alone never reloads (mtime is not a change), while any real edit does, including inode-replacing ones (`sed -i`, `perl -i`). A save that is not picked up leaves the shell rendering the previous config with no error — `qs log` shows a `Reloading configuration...` line for every save it saw, so that is the check. There is no separate build/lint/test tooling in this repo — verification is visual/behavioral via the running shell. `qmlls` (QML language server) is configured via `.qmlls.ini` for editor diagnostics.

## Architecture

`shell.qml` is the entry point: a `Scope` that instantiates the top-level pieces — `Bar`, `BarBottom`, `BarTop`, and a hidden `Launcher` — as siblings. Each top-level widget manages its own `PanelWindow`(s); there's no central layout manager.

**Import convention**: QML modules are imported by their path under the repo root using the `qs.` namespace, e.g. `import qs.widgets.launcher`, `import qs.widgets.decoration`. Sibling files in the same directory are imported with a relative string import instead (e.g. `Bar.qml` does `import "modules"`).

**Multi-monitor**: Bar/BarTop/BarBottom each wrap their `PanelWindow` in `Variants { model: Quickshell.screens }`, so one window instance is created per connected screen. `pragma ComponentBehavior: Bound` + `required property var modelData` is the standard pattern for these per-screen delegates.

**Directory layout**:
- `widgets/bar/` — `Bar.qml` is the main sidebar (right-anchored, full height) hosting the module stack (date, clock, tray, decorative dividers); `BarTop.qml`/`BarBottom.qml` are thin accent-colored strips anchored to the top/bottom edges.
- `widgets/bar/modules/` — individual bar widgets (`Clock`, `Date`, `Tray`/`TrayItem`, `Volume`) built on the shared `BarWidget` base component.
- `widgets/launcher/` — shared `AppModel` search/execution plus eight launcher variants. `ApplicationLauncher` (variant 8 and the primary `SUPER` launcher) keeps its visual core in the headlessly renderable `ApplicationLauncherContent`; variants 1–7 remain available on `SUPER CTRL 1–7` for comparison.
- `widgets/decoration/` — reusable QtQuick `Shape`-based visual accents (angled panel edges, slashes) used to give bar panels their non-rectangular look. `Dummy.qml` is a placeholder/test rectangle.
- `widgets/input/` — thin wrappers around `QtQuick.Controls` inputs (currently just `TextField`).
- `widgets/layout/` — `HorizontalStack`/`VerticalStack`: `RowLayout`/`ColumnLayout` wrappers that expose `default property alias content` for terser call sites, with a trailing filler `Item` that soaks up remaining space.
- `assets/` — SVG icons referenced via `file://${Quickshell.shellDir}/assets/...`.

**Styling**: All colors and font families come from the `Theme` singleton
(`widgets/theme/Theme.qml`, `import qs.widgets.theme`) — there are no color or
font literals left anywhere under `widgets/`. Add a token there rather than
hardcoding a value; alpha variants of the two main colors go through
`Theme.textAlpha(a)` / `Theme.accentAlpha(a)` instead of a hand-written
`Qt.rgba(...)`. Metrics (sizes, spacing) are still per-component.

**Component base pattern**: `BarWidget.qml` (`widgets/bar/modules/BarWidget.qml`) is a `WrapperMouseArea` + `WrapperRectangle` combo providing hover-triggered border highlight (`Behavior on border.color` animation) and `Layout.fillWidth`. Bar modules extend it via `default property alias content` rather than duplicating the hover/border chrome.

**Fonts**: Two families, both via `Theme`. `Theme.displayFont` / `Theme.readoutFont` (an alias of it) are `DepartureMono Nerd Font`, installed by `services/desktop/desktop-apps.nix`; `Theme.microFont` is `DejaVu Sans Mono`. The shell no longer uses `Digital-7 Mono`, which was never packaged and depended on a manual `~/.dots/fonts/digital_7` install.
