# CodexBar Plasma

Track AI provider quotas, reset times, costs, and local agent sessions from your
KDE Plasma 6 panel. CodexBar Plasma uses the
[CodexBar CLI](https://github.com/steipete/CodexBar) for provider data and
authentication. This repository contains the Linux Plasma widget only.

The same Codex, Claude, and Gemini usage in both styles. Small provider icons
sit beside primary and secondary quota capsules. Choose the appearance in
**Panel** settings. These examples show meters with panel text hidden.

Click an image for full size. Panel captures show the upcoming capsule design;
popup captures show version 0.2.34. All use Breeze Dark with synthetic data. The widget follows your Plasma theme; provider
accent colors stay consistent across themes.

## Features

- Quota meters, reset windows, account selection, and provider status in the panel
  and popup, with configurable quota warnings and Plasma notifications.
- Standard and Minimal panel styles with up to two quota capsules per provider,
  horizontal and vertical meters, selectable quota windows, conditional text
  and meters, and a live settings preview. Optional text sits beside the selected
  provider's capsules with the default order. Panel settings keep appearance and
  meters visible; additional information and quota/order/visibility options expand
  when needed.
- **Usage & Spend** with cost/token charts, a 7/30/90-day range, an activity
  heatmap, and provider, model, and project breakdowns when the CLI supplies them.
- A local **Sessions** tab. Transcript paths and working directories are never
  displayed or opened.
- Optional privacy mode, refresh on popup opening, and automatic widget updates.
- English plus Italian, French, German, Spanish, and Brazilian Portuguese,
  selected through your Plasma language preferences.

Provider authentication and data support come from the CLI. The widget includes
fallback metadata for all 69 providers in the official CodexBar 0.49.1 registry,
rechecked against CLI 0.56.2. Available metrics and setup actions vary by provider.
The proposed generic provider-settings descriptor is not available in CLI 0.57.0;
its additional editors remain unavailable.

<!-- Web links to guides also work in the installed package, which omits those files. -->
See the [usage and settings guide](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/usage.md)
for options and defaults, the [documentation index](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/README.md)
for verified CLI evidence, and [Linux parity TODO](https://github.com/Lucenx9/codexbar-plasma/blob/main/TODO.md)
for remaining Linux/Plasma work.

## Requirements

- KDE Plasma 6, `kpackagetool6`, and the `org.kde.plasma.plasma5support` QML module.
- A working `codexbar` CLI, available on Plasma's `PATH` or through an absolute
  path configured in the widget.
- `notify-send` for Plasma notifications.
- `curl`, `jq`, `python3`, `sha256sum`, and GNU `timeout` for the bundled release
  updater. GNU `timeout` also bounds CLI writes after a secret prompt.

Distribution package names vary. Source builds additionally need `make`, Python
3, and GNU gettext; see [Development](#development).

## Install

1. Install the Linux CLI from the
   [official CodexBar release tarballs](https://github.com/steipete/CodexBar/releases/latest)
   or another method documented by [upstream CodexBar](https://github.com/steipete/CodexBar).
   Third-party packages such as AUR can lag behind upstream releases.
   Set up your provider using the upstream instructions, then verify usage:

   ```sh
   codexbar usage --format json --json-only
   ```

2. Download `codexbar-plasma.plasmoid` from the widget's
   [latest release](https://github.com/Lucenx9/codexbar-plasma/releases/latest).
   In the directory containing that file, run:

   ```sh
   kpackagetool6 -t Plasma/Applet -i codexbar-plasma.plasmoid
   ```

3. Open your Plasma panel's **Add Widgets** chooser and add **CodexBar**.

4. Open the widget settings. Use **Providers** to enable providers and supported
   setup actions, **Panel** to adjust the compact display, and **General** to
   choose refresh and privacy settings.

Provider enable/disable and setup actions change the CLI configuration
immediately. **Apply** and **Cancel** cover widget settings only.

New widgets refresh quotas every five minutes and show percent **used**. Warning
and critical thresholds default to 80% and 95%. Existing settings are preserved
when you upgrade.

Failed refreshes retain quotas measured within the last 24 hours and identify
them as last known.
A redacted cache restores recent quotas after a Plasma restart while the CLI
refreshes. See [data freshness](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/usage.md#data-freshness)
for its limits.

## Update

Read the [changelog](CHANGELOG.md) for changes and upgrade notes by version.

To upgrade a release installation, download the new `.plasmoid` and run:

```sh
kpackagetool6 -t Plasma/Applet -u codexbar-plasma.plasmoid
```

Log out and back in to load the new widget code, or reload your Plasma panels
and desktop with:

```sh
systemctl --user restart plasma-plasmashell.service
```

In **General → Updates**, **Check for widget updates** and update notifications
are enabled by default. **Install widget updates automatically** is opt-in.
The bundled helper accepts only immutable GitHub releases. It binds assets to
the advertised tag, verifies SHA-256 digests and the published checksum, and
checks the applet ID and version before installation. A validation mismatch
aborts the update.

For a source checkout, see the [development update commands](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/development.md#work-from-a-checkout).

## Troubleshooting

### The widget stays on Loading or cannot find the CLI

Run `codexbar usage --format json --json-only` in a terminal. If it fails,
resolve the provider or CLI setup first. If it works, locate the executable:

```sh
command -v codexbar
```

Paste the returned absolute path into **Diagnostics → Command path**. Plasma
may have a different `PATH` from your terminal. **Use PATH** restores the
portable `codexbar` default.

### Providers, accounts, or costs are missing

Check that the provider is enabled in **Providers**, then inspect the relevant
CLI response. For example, for Codex accounts and local cost data:

```sh
codexbar usage --provider codex --all-accounts --format json --json-only
codexbar cost --format json --json-only
```

The widget can display only data the CLI returns. Cost availability varies by
provider; missing dollar amounts do not mean zero spend. If a feature is absent,
check the [usage guide](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/usage.md)
and [Linux parity TODO](https://github.com/Lucenx9/codexbar-plasma/blob/main/TODO.md).

### Notifications do not appear

Check the widget's **Notifications** settings and test desktop notifications:

```sh
notify-send "CodexBar" "Notification test"
```

### Report a problem

[Open a widget issue](https://github.com/Lucenx9/codexbar-plasma/issues/new) with
reproduction steps, expected and actual behavior, your distribution, and the
Plasma, widget, and CLI versions. For QML errors, inspect recent logs:

```sh
journalctl --user -u plasma-plasmashell.service --since '10 minutes ago' --no-pager
```

Include only relevant CodexBar errors. Redact account details, paths, credentials,
and other personal information before sharing logs or screenshots. If the CLI
command itself fails, consult [upstream CodexBar](https://github.com/steipete/CodexBar)
for provider setup and CLI support.

## Development

Build and install from a checkout:

```sh
git clone https://github.com/Lucenx9/codexbar-plasma.git
cd codexbar-plasma
make install
```

Then reload Plasma as described under [Update](#update).
Run `make check` before submitting changes. The
[development guide](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/development.md)
covers dependencies, checks, isolated popup smoke tests, packaging, and QML
conventions. See the [documentation index](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/README.md)
for maintained references.

Contributions to the Plasma widget are welcome through
[pull requests](https://github.com/Lucenx9/codexbar-plasma/pulls). Include the
verification results requested by the PR template. Provider logic and CLI
contracts belong upstream. To add or improve a language, follow the
[translation guide](https://github.com/Lucenx9/codexbar-plasma/blob/main/docs/translations.md).
CLI-supplied free-form text retains its original language.
