+
+### Fixed
+- **Cloudflare 403 bypass** — API requests blocked by Cloudflare JS challenges now fall back to headless Chrome with the persistent browser profile, which can solve the challenges natively
+
+### Added
+- `internal/browser/fetch.go` — headless Chrome API fetcher using chromedp with the existing browser profile (reuses Cloudflare clearance cookies)
+- `fetchWithFallback()` in fetcher — tries plain HTTP first, falls back to headless Chrome on 403
+
+## [0.3.0] — 2026-02-26
+
+Full rewrite from Node.js + Python to Go. Each platform gets a single static binary — no runtime dependencies.
+
+### Changed
+- **Complete Go rewrite** — replaced Node.js statusline/fetcher and Python widget with three Go binaries
+- **Zero dependencies** — no Node.js, Python, pip, pystray, or system packages needed
+- **Native packaging** — `.deb` for Debian/Ubuntu, `.zip` with static binaries for Windows, `.tar.gz` for Linux
+- **CI/CD** — pipeline now cross-compiles Linux + Windows binaries and builds .deb via nfpm
+
+### Added
+- `claude-widget` — system tray icon (fyne-io/systray) with built-in fetcher and icon renderer (fogleman/gg)
+- `claude-statusline` — CLI one-liner for Claude Code status bar (reads stdin + cache)
+- `claude-fetcher` — standalone cron job (reads session key, fetches usage, writes cache)
+- `.deb` package with autostart .desktop file and cron.d entry
+- Windows cross-compilation with `-H=windowsgui` for console-free widget
+

 ## Overview

-Both components share the same session key and fetcher logic. Install one or both depending on your setup.
+Two static binaries built from one Go codebase. No runtime dependencies — no Node.js, Python, or system packages needed. A `setup` tool handles installation and uninstallation on both platforms.

-### CLI Statusline (Node.js)
+### CLI Statusline

-A headless-friendly status bar for Claude Code. Shows context window utilization and token usage as text progress bars, piped into the Claude Code statusline slot.

 ```
 Context ▓▓▓▓░░░░░░ 40% | Token ▓▓░░░░░░░░ 19% 78M
 ```

-### Usage Fetcher (Node.js)
+### Desktop Widget

-Standalone cron job that fetches token usage from the Claude API and writes a JSON cache file. The CLI statusline reads this cache. Runs independently — no browser or GUI needed.
-
-### Desktop Widget (Python)
-
-Cross-platform system tray icon that shows the 5-hour usage window as a circular progress bar overlaid on a Claude starburst logo. Color shifts from green through amber to red as usage increases. Right-click menu shows detailed usage stats, reset timers, and configuration.

-Only one fetcher needs to run. Either `fetch-usage.js` (via cron) or the widget's built-in fetcher thread writes to the shared cache at `/tmp/claude_usage.json`. Both consumers read from it:
-
- **CLI statusline** reads the cache on every Claude Code render cycle
- **Desktop widget** reads the cache on startup for instant display, then either fetches itself (writing back to cache) or detects that the cache is already fresh (from cron) and skips the API call
-
-If both fetchers happen to run, they write the same format — last writer wins, no conflicts.

 ## Installation

-### Quick Install (from release)
+### Windows / Linux (setup tool)

-Download the latest archive from the [Releases page](https://git.davoryn.de/calic/claude-statusline/releases) for your platform:
-
-| Platform | Download | Install |
-|----------|----------|---------|
-| **Linux** | `.tar.gz` source archive | Extract, then `bash install.sh` |
-| **macOS** | `.tar.gz` source archive | Extract, then `bash install.sh` |
-| **Windows** | `.zip` source archive | Extract, then run `install.ps1` (see [Windows Quick Start](#windows-quick-start) below) |
-
-> **Planned:** Native installers (`.deb`, `.msi`) are on the roadmap. For now, releases contain source archives.
-
-### Developer Install (from source)
-
-Clone the repository and run the installer wizard:
-
-**Linux / macOS:**
-```bash
-git clone https://git.davoryn.de/calic/claude-statusline.git
-cd claude-statusline
-bash install.sh
-```
-
-**Windows (PowerShell):**
-```powershell
-git clone https://git.davoryn.de/calic/claude-statusline.git
-cd claude-statusline
-powershell -ExecutionPolicy Bypass -File install.ps1
-```
-
-### What the wizard does
-
-1. Asks which components to install (CLI statusline, desktop widget, or both)
-2. Guides you through session key setup
-3. Configures autostart (widget) or cron (CLI fetcher) as applicable
-4. Sets up the Claude Code statusline integration
-
-### Windows Quick Start
-
-If you're new to the command line, follow these steps:
-
-1. Go to the [Releases page](https://git.davoryn.de/calic/claude-statusline/releases) and download the latest `.zip` file
-2. Extract the zip to any folder (e.g. `C:\Users\YourName\claude-statusline`)
-3. Open the extracted folder in File Explorer
-4. Right-click `install.ps1` and select **Run with PowerShell**
-   - If you see a security prompt, choose **Run anyway** or **Open**
-   - Alternatively, open PowerShell manually and run:
-     ```powershell
-     powershell -ExecutionPolicy Bypass -File install.ps1
-     ```
-5. The wizard will walk you through component selection and session key setup
-6. To find your session key, see [Session Key](#session-key) below
-
-### Prerequisites
-
-| Component | Requires |
-|-----------|----------|
-| CLI Statusline + Fetcher | Node.js 18+ |
-| Desktop Widget | Python 3.9+, pip |
-| Desktop Widget (Linux) | `python3-gi`, `gir1.2-ayatanaappindicator3-0.1` (installed by wizard) |
-
-## Session Key
-
-Both components authenticate via a session cookie from claude.ai.
-
-```mermaid
-sequenceDiagram
-  participant User
-  participant Browser
-  participant Installer
-  participant Config
-
-  User->>Browser: Log into claude.ai
-  User->>Browser: DevTools → Cookies → sessionKey
-  User->>Installer: Paste session key when prompted
-  Installer->>Config: ~/.config/claude-statusline/session-key
-```
-
-**Step by step:**
-
-1. Log into [claude.ai](https://claude.ai) in any browser
-2. Open DevTools (press `F12`), go to **Application** → **Cookies** → `https://claude.ai`
-3. Copy the value of the `sessionKey` cookie (it starts with `sk-ant-`)
-4. The installer will prompt you to enter it, or set it manually:
+Extract the archive and run the setup tool. It copies binaries to the install directory, enables autostart for the widget, and configures Claude Code's statusline setting.

 ```bash
+# Windows — double-click setup.exe, or from a terminal:
+setup.exe
+
+# Linux
+./setup
+```
+
+### Debian/Ubuntu (.deb)
+
+```bash
+sudo dpkg -i claude-statusline_0.3.0_amd64.deb
+```
+
+Installs binaries to `/usr/bin/` and sets up autostart for the widget.
+
+### Linux (manual)
+
+```bash
+tar xzf claude-statusline_0.3.0_linux_amd64.tar.gz
+cp claude-statusline-0.3.0/claude-{statusline,widget} ~/.local/bin/
+```
+
+### Session Key Setup
+
+After installing, paste your claude.ai session key:
+
+```bash
+mkdir -p ~/.config/claude-statusline
 echo "sk-ant-..." > ~/.config/claude-statusline/session-key
 chmod 600 ~/.config/claude-statusline/session-key
 ```

-Alternatively, set the `CLAUDE_SESSION_KEY` environment variable.
+**To find your session key:**
+1. Log into [claude.ai](https://claude.ai)
+2. Open DevTools (`F12`) → **Application** → **Cookies** → `https://claude.ai`
+3. Copy the `sessionKey` cookie value
+
+Or set `CLAUDE_SESSION_KEY` as an environment variable.
+
+### Claude Code Integration
+
+Add to your Claude Code settings (`~/.claude/settings.json`):
+
+```json
+{
+  "statusLine": {
+    "type": "command",
+    "command": "claude-statusline"
+  }
+}
+```
+
+## Uninstall
+
+### Windows / Linux (setup tool)
+
+```bash
+# Windows
+setup.exe --uninstall
+
+# Linux
+./setup --uninstall
+```
+
+Stops the widget, removes binaries and autostart entry, and cleans the `statusLine` setting from Claude Code. Optionally removes the config directory (interactive prompt, default: keep).
+
+### Debian/Ubuntu
+
+```bash
+sudo dpkg -r claude-statusline

- * Claude Usage Fetcher (Standalone)
- *
- * Fetches token usage from claude.ai API using a session key.
- * Designed to run as a cron job on headless servers.
- *
- * Session key source (checked in order):
- *   1. CLAUDE_SESSION_KEY env var
- *   2. ~/.config/claude-statusline/session-key  (plain text file)
- *
- * To get your session key:
- *   1. Log into claude.ai in any browser
- *   2. Open DevTools → Application → Cookies → claude.ai
- *   3. Copy the value of the "sessionKey" cookie
- *   4. Save it: echo "sk-ant-..." > ~/.config/claude-statusline/session-key
- *
- * Output: Writes JSON to $CLAUDE_USAGE_CACHE or /tmp/claude_usage.json
- *
- * Cron: every 5 min (see install.sh or README for crontab line)

calic	a11bdb7267	Stealth mode: defeat Cloudflare automation detection Some checks failed Release / build (push) Failing after 1m5s Details Drop DefaultExecAllocatorOptions (includes --enable-automation), add disable-blink-features=AutomationControlled, patch navigator.webdriver via JS, and inject sessionKey cookie via CDP into a dedicated fetch profile. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-21 00:42:03 +01:00
calic	5abdee06ff	Add diagnostic logging to Chrome fallback All checks were successful Release / build (push) Successful in 1m32s Details Log navigation, polling state, and response snippets so we can diagnose whether the fallback fails due to Cloudflare challenge, login redirect, profile lock, or other issues. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-21 00:34:41 +01:00
calic	2cb89d3c54	Fix Cloudflare headless detection: use non-headless with hidden window All checks were successful Release / build (push) Successful in 1m37s Details Cloudflare detects headless Chrome and loops the JS challenge forever. Switch to non-headless mode with an off-screen window. Also save Cloudflare cookies (cf_clearance, __cf_bm) after Chrome fallback so subsequent plain HTTP requests can reuse them. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-21 00:26:34 +01:00
calic	ba3b73c3dd	Add Cloudflare 403 fallback via headless Chrome All checks were successful Release / build (push) Successful in 1m40s Details Plain HTTP requests to claude.ai get blocked by Cloudflare JS challenges (403). The fetcher now falls back to headless Chrome using the persistent browser profile, which can solve challenges natively and reuses existing cf_clearance cookies. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-21 00:13:21 +01:00
Axel Meyer	47165ce02c	Remove standalone fetcher, add setup tool with install/uninstall workflow All checks were successful Release / build (push) Successful in 1m45s Details Drop claude-fetcher binary and cron job — the widget's built-in BackgroundFetcher is the sole fetcher now. Add cmd/setup with cross-platform install and uninstall (--uninstall): kills widget, removes binaries + autostart, cleans Claude Code statusline setting, optionally removes config dir. Also includes: browser-based login (chromedp), ICO wrapper for Windows tray icon, and reduced icon size (64px). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-26 19:11:08 +01:00
Axel Meyer	5b0366f16b	Fix CI: remove golang container, install Go in-step All checks were successful Release / build (push) Successful in 1m25s Details The golang:1.23 container image lacks Node.js, causing actions/checkout@v4 to fail. Use the default runner image (which has Node) and install Go manually. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-26 15:28:52 +00:00
Axel Meyer	7f17a40b7c	Rewrite in Go: static binaries, zero runtime dependencies Some checks failed Release / build (push) Failing after 21s Details Replace Node.js + Python codebase with three Go binaries: - claude-statusline: CLI status bar for Claude Code - claude-fetcher: standalone cron job for API usage - claude-widget: system tray icon (fyne-io/systray + fogleman/gg) All CGO-free for trivial cross-compilation. Add nfpm .deb packaging with autostart and cron. CI pipeline produces Linux + Windows binaries, .deb, .tar.gz, and .zip release assets.
