# showy-quota

Always-on AI plan quota strips for **[SketchyBar](https://github.com/FelixKratz/SketchyBar)**, **[Zellij](https://github.com/zellij-org/zellij)**, and **[tmux](https://github.com/tmux/tmux)**,
driven by [CodexBar](https://github.com/steipete/CodexBar).

Beautiful, themeable, minimal.

### Features
- **Zero auth/config:** Relies entirely on CodexBar for credentials and parsing.
- **Provider status (SketchyBar):** Icons automatically tint yellow (minor/maintenance) or red (major/critical) during an outage. Clicking a degraded icon opens the provider's official status page.
- **Pacing & thresholds:** Renders proportional pacing markers where the surface supports them and color-codes usage (good/warn/bad) based on configurable remaining-quota and time thresholds.
- **Themeable:** Ships with Catppuccin, Nord, Dracula, Tokyo Night, and others.
- **Low overhead:** Host bars share one cached fetcher; Zellij can use a single WASM artifact.

## Quickstart

1. **Install and enable CodexBar.** It is the only thing that talks to providers.

```sh
   brew install --cask steipete/tap/codexbar          # macOS
   # CLI tarball / Linux: https://github.com/steipete/CodexBar/releases
   codexbar usage --format json | jq length           # should print 1 or more
   ```

On macOS, cookie-based providers also need Full Disk Access for CodexBar in
   **System Settings → Privacy & Security**. If `jq length` prints `0`, fix
   CodexBar before continuing — showy-quota has nothing to paint without it.

2. **Install showy-quota.**

Recommended release tarball path for shell integrations (SketchyBar, tmux,
   and the advanced Zellij/zjstatus driver):

```sh
   # Pick the asset for your platform: macos-arm64, macos-x86_64, or linux-x86_64.
   VERSION=$(curl -fsSL https://api.github.com/repos/enieuwy/showy-quota/releases/latest | jq -r '.tag_name | sub("^v"; "")')
   TARGET=macos-arm64
   curl -LO "https://github.com/enieuwy/showy-quota/releases/download/v${VERSION}/showy-quota-${VERSION}-${TARGET}.tar.gz"
   curl -LO "https://github.com/enieuwy/showy-quota/releases/download/v${VERSION}/showy-quota-${VERSION}-${TARGET}.tar.gz.sha256"
   shasum -a 256 -c "showy-quota-${VERSION}-${TARGET}.tar.gz.sha256"
   # If your system uses GNU coreutils, use:
   # sha256sum -c "showy-quota-${VERSION}-${TARGET}.tar.gz.sha256"
   tar xzf "showy-quota-${VERSION}-${TARGET}.tar.gz"
   cd "showy-quota-${VERSION}"
   make install-copy             # copies runtime files into ~/.local/share/showy-quota
   ```

Per-platform tarballs include the prebuilt native `showy-quota-render`
   binary beside the shell entry points, so installing from a release does not
   require Rust or Cargo.

Developer/source mode keeps symlinks into your checkout:

```sh
   git clone https://github.com/enieuwy/showy-quota && cd showy-quota
   make doctor                   # bash 4+, jq, codexbar present
   make install                  # symlinks bin/* into ~/.local/bin
   ```

Zellij's standalone plugin can still be installed by downloading
   `showy-quota-zellij.wasm`; see [`docs/plugin.md`](docs/plugin.md). From
   source, `make install-plugin` builds and installs it. `make install-copy`,
   `make install`, and `make install-plugin` refuse to clobber existing files
   unless you run with `FORCE=1`.

3. **Wire a UI.** Pick the UI(s) you use:

- **SketchyBar:** `make install-copy-sketchybar` for a release/copy install
     (or `make install-sketchybar` for dev symlinks), then add
     `source "$ITEM_DIR/showy_quota.sh"` to your `sketchybarrc` and reload.
   - **tmux:** use the TPM wrapper or paste the snippet in
     [tmux wiring](#tmux-wiring) into `~/.tmux.conf`.
   - **Zellij:** install `showy-quota-zellij.wasm`, paste the layout fragment.
     See [`docs/zellij.md`](docs/zellij.md) and [`docs/plugin.md`](docs/plugin.md).
   - **Agent CLI statusline:** point Claude Code (or any command-backed status
     line) at `adapters/agent-cli/showy-quota-statusline`; see
     [`docs/statusline.md`](docs/statusline.md).

### SketchyBar wiring

Install the SketchyBar item/plugin, then add the item declaration to
`~/.config/sketchybar/sketchybarrc` after `ITEM_DIR` and `PLUGIN_DIR` are
defined:

```sh
make install-sketchybar
source "$ITEM_DIR/showy_quota.sh"
```

Then reload SketchyBar (`sketchybar --reload` or quit + relaunch) once to
load the trigger item. One icon + bar + label triple appears per provider
currently fetching usage data; later provider adds/removals land on the next
plugin tick without another reload.

### Zellij wiring

Two pieces:

1. **Plugin pane** — install `showy-quota-zellij.wasm` and paste
   `adapters/zellij/layout-pane.kdl.fragment` into your default layout. It
   declares one visible standalone plugin pane; no `zjstatus` or feeder loop is
   needed.
2. **Detail keybind** — paste `adapters/zellij/detail-pane.kdl.fragment` into your
   keybinds block. Default is `Alt /`.

Reload Zellij to pick up the new layout/keybind. Advanced users who want
showy-quota inside an existing multi-widget zjstatus row can keep using
`showy-quota-zellij-pipe`; see [`docs/zellij.md`](docs/zellij.md).

### tmux wiring

TPM users can install the wrapper directly:

```tmux
set -g @plugin 'enieuwy/showy-quota'

# Optional: bind the detail popup. Pick any prefix-relative key you prefer.
set -g @showy-quota-popup-key '/'
```

The TPM wrapper adds the existing `bin/showy-quota-tmux-bar` renderer to
`status-right`; it does not introduce a second tmux implementation. Without
TPM, wire the same renderer manually:

```sh
# Use the absolute path — tmux's PATH at server start typically lacks ~/.local/bin.
CB_BIN="$HOME/.local/bin"
cat >> ~/.tmux.conf <<TMUX
set -g status-right-length 300
if -F '#{m:*showy-quota-tmux-bar*,#{status-right}}' '' 'set -ag status-right " #(${CB_BIN}/showy-quota-tmux-bar)"'
bind-key "/" display-popup -E -h 36 -w 92 -T "CodexBar usage" 'config="\${XDG_CONFIG_HOME:-\$HOME/.config}/showy-quota/config.env"; [ -r "\$config" ] && . "\$config"; while :; do clear; "\${SHOWY_QUOTA_CODEXBAR_BIN:-codexbar}" usage; sleep 30; done'
TMUX
tmux source ~/.tmux.conf
```

No `watch(1)` dependency — the popup uses a tiny shell loop so this works on a
stock macOS install.

### Terminal rendering modes

Terminal strips default to an `auto` mode that picks a body layout per
provider:

- **`dual`** (default for most providers): a primary-over-secondary
 half-block layout. Each window is colored by its remaining-quota severity
 and dimmed when it is a weekly/monthly cap; both rows show a pacing marker
 (the `elapsed` color tints the upper half for the primary window and the
 lower half for the secondary). Body width is 12 cells. <img src="docs/images/dual-terminal.png" alt="dual terminal rendering layout" width="420">
- **`mono3`** (default for `gemini`, `cursor`): packs primary,
 secondary, and tertiary into a single sextant cell per column with
 top/middle/bottom rows. Uses a single provider-level foreground color
 and `mono_markers` pacing separators. Providers whose windows share one
 billing cycle (same reset and window length, e.g. Cursor's Total/Auto/API)
 stay at full brightness and show a single pacing marker. <img src="docs/images/mono3-terminal.png" alt="mono3 terminal rendering layout" width="420">
- **`mono4`** (opt-in): packs four per-pool windows (e.g. Antigravity's
 Gemini and Claude+GPT session/weekly pools, from `extraRateWindows`) into
 a single octant cell per column. Like `mono3` but four lanes — requires an
 octant-capable terminal (Ghostty, kitty, WezTerm); run
 `python3 docs/scripts/preview-quad-octants.py` to test yours. <img src="docs/images/mono4-terminal.png" alt="mono4 terminal rendering layout" width="190">
- **`dual2`** (auto-detected for model-pooled providers like `antigravity`):
 splits the provider into one standalone `dual` per pool (`AGᴳ` for Gemini,
 `AGᶜ` for Claude+GPT), each from `extraRateWindows` and rendered by the
 normal half-block `dual` path. Half-blocks render in every terminal (unlike
 `mono4`). `auto` engages the split when a provider's extras carry all its
 positional slots; a single pool stays one plain `dual` (Antigravity via OAuth
 reports only Gemini). Force the split per provider with
 `SHOWY_QUOTA_PROVIDER_MODES=<provider>=dual2`. <img src="docs/images/dual2-terminal.png" alt="dual2 terminal rendering layout" width="438">

Customize terminal layout with `SHOWY_QUOTA_TERMINAL_BAR_MODE=dual|dual2|mono3|mono4`.
For per-provider auto-mode selection and marker behavior, use
`SHOWY_QUOTA_PROVIDER_MODES` (e.g. `antigravity=mono4`),
`SHOWY_QUOTA_MONO_COLOR_MODE`, and `SHOWY_QUOTA_MONO_MARKERS`.

Stuck? `bin/showy-quota --diagnose` (or `make diagnose`) prints exactly the
state a bug report needs; `bin/showy-quota --diagnose --json` emits the same
diagnostic surface as stable machine-readable JSON.

## Automation & prompts

Two subcommands read the same provider metrics the bars use — see
[`docs/automation.md`](docs/automation.md) for the full reference (exit codes,
`--json` schema, hook/cron recipes, and prompt snippets for starship,
powerlevel10k, and plain `PS1`).

- **`showy-quota guard`** gates CI, cron, and agent hooks on quota thresholds
  with stable exit codes (`0` pass, `1` breach, `2` unusable data, `3` usage):

```sh
  # Fail (exit 1) if codex or claude drops below 15% remaining
  showy-quota guard --provider codex,claude --min-remaining 15
  ```

- **`showy-quota prompt`** prints a one-line segment (`CX 92% 3:02`) for the
  worst-remaining provider. It reads the cache as-is, so it never blocks a
  shell. In starship:

```toml
  # ~/.config/starship.toml
  [custom.showy_quota]
  command = 'showy-quota prompt'
  when = true
  shell = ['bash', '--noprofile', '--norc']
  format = '[$output]($style) '
  style = 'bold yellow'
  ```

## Requirements

- **macOS** for SketchyBar. Zellij/tmux bars also work on Linux when CodexBar
  can fetch your chosen providers.
- A CodexBar data source:
  - Zellij plugin: `codexbar` on the Zellij server `PATH`; the plugin starts
    `codexbar serve` by default, uses `/health` + `/usage`, and visibly marks
    CLI fallback as `⚠cli`;
  - shell integrations: same managed serve path via `showy-quota-fetch`, with
    visible `⚠cli` fallback.
  CodexBar's web-backed providers remain macOS-only; CLI/OAuth/API/local
  providers work where CodexBar supports them.
- Shell integrations need `bash` 4+, `jq`, and a `date` that understands either
  `-j -f` (BSD/macOS) or `-d` (GNU coreutils).
  The standalone Zellij plugin does not need the shell scripts, `bash`, or `jq`.
- SketchyBar integration also needs `sketchybar` on the PATH. Font icon mode
  needs `sketchybar-app-font`; SVG fallback icons need ImageMagick 7+
  (`magick`). Native usage rows do not need `magick`.
- The Zellij/tmux renderers wrap each provider chunk in Powerline-Extra end
  caps (U+E0B6 / U+E0B4). Any Nerd Font ships these. For the standalone
  Zellij plugin with a non-Nerd font, set `cap_left ""` and `cap_right ""`
  in the plugin KDL; for tmux or advanced zjstatus, set
  `SHOWY_QUOTA_CAP_LEFT=` / `SHOWY_QUOTA_CAP_RIGHT=`. Terminal sextant modes
  have additional font notes in `docs/zellij.md` and `docs/tmux.md`.
- Optional: `flock` for inter-process locking; falls back to an owner-scoped
  `mkdir` lock when missing.
- Development/install commands are written for GNU-compatible `make`; on
  systems with a non-GNU default make, use `gmake` or invoke the scripts
  directly.

## Configuration

The shell integrations (SketchyBar, tmux, and the Zellij shell renderers) read
optional overrides from `~/.config/showy-quota/config.env`. The standalone Zellij WASM plugin is configured with
KDL keys instead (the same names without the `SHOWY_QUOTA_` prefix, lowercased);
see [`docs/plugin.md`](docs/plugin.md#configuration).

Config is optional; create it only for values you want to override. The full environment surface lives in
[`share/config.env.example`](share/config.env.example) — most users only need these:

| Variable | Effect |
|---|---|
| `SHOWY_QUOTA_THEME` | Load a named built-in or user palette. default=unset (default palette) |
| `SHOWY_QUOTA_PROVIDERS` | Ordered provider allow-list; empty renders CodexBar's enabled providers. default=empty |
| `SHOWY_QUOTA_PROVIDERS_EXCLUDE` | Provider deny-list applied after the allow-list. default=empty |
| `SHOWY_QUOTA_PROVIDER_ORDER` | Stable render order without filtering. default=`codex,claude,copilot,opencode,gemini` |
| `SHOWY_QUOTA_REFRESH_SECONDS` | Freshness contract: full-refresh cadence and CLI-fallback interval. Serve collection and /usage-poll defaults derive from it. default=`120` |
| `SHOWY_QUOTA_MANAGE_SERVE` | Start `codexbar serve` automatically before CLI fallback; set `0` to disable. default=`1` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_URL` | Local `codexbar serve` base URL; set empty to skip HTTP probing. default=`http://127.0.0.1:8080` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_TIMEOUT_SECONDS` | Bounded positive timeout for local `/health` probes. configured default=`10` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_USAGE_TIMEOUT_SECONDS` | Bounded positive timeout for local `/usage` probes. default=`30` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_PORT` | Port passed to managed `codexbar serve --port`. default=`8080` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_REFRESH_INTERVAL_SECONDS` | Collection cadence for a managed `codexbar serve`. default=`SHOWY_QUOTA_REFRESH_SECONDS` |
| `SHOWY_QUOTA_CODEXBAR_SERVE_REFRESH_SECONDS` | /usage re-read cadence when `codexbar serve` is available. default=`SHOWY_QUOTA_REFRESH_SECONDS / 2` |
| `SHOWY_QUOTA_TIME_WARN_MINUTES` | Urgent countdown threshold. default=`30` |
| `SHOWY_QUOTA_SKETCHYBAR_CLICK` | Default SketchyBar click action; degraded icons open provider status URLs. default=`open -b com.steipete.codexbar` |

Palette overrides use role-first primary keys such as
`SHOWY_QUOTA_PALETTE_PRIMARY_*`; long-horizon windows are dimmed from the
primary palette with `SHOWY_QUOTA_PALETTE_DIM_SCALE` after
`SHOWY_QUOTA_DIM_WINDOW_MINUTES`. There are no separate secondary/tertiary
palette overrides; see `share/config.env.example` for the full palette surface.

## Verification

```sh
make doctor      # check runtime prerequisites
make test        # smoke tests over JSON fixtures
make plugin      # build showy-quota-zellij.wasm
make diagnose    # printable bug-report state (`bin/showy-quota --diagnose --json` for JSON)
```

Cache lives at `${XDG_CACHE_HOME:-~/.cache}/showy-quota/usage.json`.
If that file is corrupt, the fetcher moves it aside as
`usage.json.corrupt.<epoch>.<pid>` and keeps only the newest few quarantine
files for diagnostics. `make clean` clears cache artifacts.

## How it stays cheap

- tmux, SketchyBar, and advanced zjstatus share one cached fetcher. It prefers
  `codexbar serve`, starts it when absent, and marks CLI fallback as `⚠cli`.
- The standalone Zellij plugin uses the same serve-first shape and keeps
  in-memory last-known-good output per pane.
