DankCalendar is a standalone calendar app that brings your Local, [Google](https://calendar.google.com/), [Microsoft](https://outlook.com/), [CalDAV](https://en.wikipedia.org/wiki/CalDAV), and [iCloud](https://www.icloud.com/calendar/) calendars together in one place. It runs as a lightweight daemon with a tray icon, keeps your accounts in sync, and reminds you about events — all with the look and feel of [DankMaterialShell](https://github.com/AvengeMedia/DankMaterialShell).

## Repository Structure

This is a monorepo containing both the calendar interface and the core backend services:

## Installation

### Arch Linux (AUR)

```bash
# Prebuilt binary
yay -S dankcalendar-bin

# Build from latest git
yay -S dankcalendar-git
```

### From Source

```bash
sudo make install
```

This installs:

- `dcal` binary to `/usr/local/bin` (the Quickshell UI is embedded in the binary)
- Desktop entry + icon

Override the prefix with `PREFIX=/usr sudo make install`.

At launch the embedded UI is unpacked read-only into the session runtime dir
(`$XDG_RUNTIME_DIR/dankcal-shell/`, tmpfs) and verified against the binary on
every start, so editing the unpacked files has no effect. To run a modified
copy of the UI, point dcal at any directory containing a `shell.qml` with
`dcal -c <dir>` or the `DANKCAL_SHELL_DIR` environment variable — there is no
implicit filesystem lookup otherwise.

Optional session service (starts the daemon at login, restarts on failure):

```bash
make install-systemd
systemctl --user enable --now dcal
```

You can also toggle **Start at login** from Settings → General, which manages
an XDG autostart entry that launches `dcal run -d --hidden`.

### Requirements

- [Quickshell](https://quickshell.org) (`qs`)
- Qt 6 declarative (including `Qt.labs.platform` for the tray icon)
- Go 1.25+ (build only — the binary is pure Go, no CGO)

## Features

**Multiple Providers**
Connect Local, Google, Microsoft, CalDAV, and iCloud accounts and view every
calendar in a single unified agenda.

**Background Sync**
A lightweight daemon keeps your accounts in sync and serves the UI over IPC.
Closing the window only hides it — sync and reminders keep running.

**Event Reminders**
Native desktop notifications for upcoming events, with per-event and
per-calendar reminder configuration.

**Tray Integration**
A system tray icon to show, hide, and quit the app, plus quick access to
upcoming events.

**Secure Credentials**
OAuth tokens and account secrets are stored in your system keyring, never in
plaintext.

**Keyboard Navigation**
Full keyboard-driven navigation with a shortcuts overlay, plus spotlight-style
search across your events.

**Localized**
User-facing strings are translatable and managed through POEditor.

## Usage

```bash
dcal           # launch, or show/focus the window if already running
dcal show      # same as above
dcal show --view day   # open (or focus) directly on a view: month|week|day|agenda
dcal toggle    # toggle window visibility
dcal run       # run in the foreground (logs to the terminal)
dcal run -d    # run as a background daemon
dcal restart   # restart the running shell
dcal kill      # stop everything
```

Closing the window only hides it — the daemon and tray icon keep running.
Reopen from the tray icon, the desktop entry, or `dcal show`. Quit entirely
from the tray menu or `dcal kill`.

Manage accounts and sync from the command line:

```bash
dcal account list                 # list connected accounts
dcal account add local ~/cal      # add a local calendar directory
dcal account add caldav           # add a CalDAV / iCloud account
dcal account setup google         # OAuth setup for Google
dcal account setup microsoft      # OAuth setup for Microsoft
dcal account remove <account-id>  # remove an account
dcal sync [account-id]            # force a sync
dcal reminders                    # list upcoming reminders
```

## IPC

The daemon exposes a scriptable IPC surface — handy for keybinds and automation:

```bash
dcal ipc ui.toggle
dcal ipc ui.show
dcal ipc ui.show view=day          # open on a specific view: month|week|day|agenda
dcal ipc ui.openEvent uid=<uid>    # open a specific event's details window
dcal ipc events.list from=2026-06-01 to=2026-06-30
dcal ipc accounts.list
dcal ipc reminders.upcoming
dcal ipc system.autostart
```

## Development

```bash
make run    # build and run against the in-repo quickshell config
make test   # run the Go test suite
make fmt    # format Go code
```

> **Tip:** Run with hot reload to pick up QML changes without restarting:
>
> ```bash
> # from core/
> DCAL_ENABLE_HOTRELOAD=1 go run ./cmd/dcal run -c ../quickshell
> ```

Install [prek](https://prek.j178.dev/) and activate the hooks:

```bash
prek install
```

The hooks run `gofmt -s`, `go vet`, `go mod tidy`, and the Go test suite for
changes under `core/`, plus generic whitespace/YAML checks.
