2026-02-17Align codebase with Go best practices (ordering and style)v0.10.1Paul Buetow
- Fix struct field alignment in Config and runState - Move parseBool() after Config methods (group methods together) - Move interface satisfaction checks after type definitions in store.go - Move linkScales var to top of display.go with other declarations - Clean up orphaned comment and blank line - Bump version to 0.10.1 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-16Add toggleable host separator lines (hotkey s)Paul Buetow
Draw 1px yellow vertical lines between hosts when monitoring multiple servers, making it easy to see where one host's bars end and the next begins. Toggled with hotkey 's', persisted via 'w' to ~/.loadbarsrc. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-16Display GuestNice CPU metric as lime green segment above NicePaul Buetow
Expand the smoothed CPU array from [9] to [10] elements to include GuestNice (index 9). Drawn in lime green above Nice (green) in the CPU bar stack. Rename normalizePcts9 to normalizePcts. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-16Add global I/O avg line (hotkey i) and m/n hotkey aliasesPaul Buetow
Add a pink 1px line drawn from the top showing mean iowait+IRQ+softIRQ across all hosts, toggled with hotkey i and persistable to ~/.loadbarsrc. Also add m as alias for 2 (memory toggle) and n as alias for 3 (network toggle) for easier single-hand operation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-16Add global average CPU line toggled with hotkey gv0.10.0Paul Buetow
Draw a 1px red horizontal line spanning the full window width showing the mean CPU usage across all monitored hosts. Toggled with 'g' hotkey and persistable to ~/.loadbarsrc via 'w'. Bump version to 0.10.0. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-16Fix multi-core display bug: distribute remainder pixels evenlyv0.9.1Paul Buetow
Fixes issue where integer division (winW / numBars) left unused pixels on the right side of the window. The more cores displayed, the more obvious the gap became. Changes: - Add barBounds() helper to calculate exact position and width for each bar - Distribute remainder pixels evenly using scaled division - Update drawing functions to use pre-calculated positions - Update test to verify bars now fill entire window width Increment version to 0.9.1 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-14Aggregate all net interfaces, remove n hotkey, fix net bar decay bugv0.9.0Paul Buetow
Sum RX/TX across all non-lo interfaces instead of picking a single one. Remove the n hotkey (cycle interface), netint config field, and --netint flag since they are no longer needed. Fix pre-existing bug where net bars decayed to zero between collector updates (~19 of 20 frames had target=0, making bars invisible even during heavy downloads).

2026-02-14Implement f/v hotkeys for link scale and add hotkey unit testsPaul Buetow
Add missing f/v hotkey handlers to cycle NetLink through mbit/10mbit/100mbit/gbit/10gbit, closing the gap between README documentation and actual implementation. Add 13 unit tests covering all hotkey behaviors including visual pixel assertions for toggles. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-14Remove macOS stats gathering support, require Linux with /procv0.8.4Paul Buetow
Remove non-functional macOS monitoring code that used native tools (sysctl, vm_stat, netstat, iostat). Now loadbars exits with an error when attempting local stats gathering on non-Linux systems. macOS can still be used as a client to monitor remote Linux servers via SSH.
2026-02-14Replace static screenshot with animated GIF in READMEPaul Buetow
Crop window decoration borders from the recording and update the README image reference from loadbars.png to loadbars.gif. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-14Add GIF recording helper script for Wayland and X11Paul Buetow
Supports Wayland (grim + slurp for frame capture) and X11 (ffmpeg x11grab + xdotool). Converts to GIF via gifski or ffmpeg palettegen fallback. Includes cleanup trap, dependency checks, and configurable duration/fps/output. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
2026-02-14Fix stale pixels at right edge when toggling bar layoutv0.8.3Paul Buetow
drawFrame() only cleared the window on layout changes, leaving remainder pixels (from integer division winW/numBars) with stale content from the double-buffered back buffer. Now clears every frame per SDL2 best practice. Adds comprehensive SDL visual test harness using software renderer with pixel spot-checking for CPU, memory, network bars, and the remainder bug.

2026-02-14Consolidate macOS documentation into README.md and AGENTS.mdPaul Buetow
2026-02-14Add macOS support with automatic window activationPaul Buetow
This commit adds full macOS support for loadbars, allowing it to run natively on macOS for both localhost monitoring and remote Linux hosts. Key changes: - Embed both Linux and Darwin monitoring scripts in the binary - Auto-detect localhost OS and use appropriate script - Darwin script uses native macOS tools (sysctl, vm_stat, netstat, iostat) - Remote hosts always use Linux script (assumes /proc filesystem) - Automatic window activation on macOS using build tags - No external helper scripts needed The binary now works seamlessly on macOS: - localhost monitoring uses macOS-specific commands - Remote Linux hosts work via SSH with Linux script - SDL window automatically comes to foreground on macOS - Cross-platform build with single binary for all scenarios Technical implementation: - internal/collector/script.go: Embeds both scripts - internal/collector/loadbars-remote-darwin.sh: macOS monitoring - internal/collector/loadbars-remote.sh: Linux monitoring (copied from scripts/) - internal/display/activate_darwin.go: macOS window activation - internal/display/activate.go: No-op for other platforms - Updated README.md with macOS installation instructions - Added MACOS.md with detailed macOS documentation

2026-02-13Revert "Replace Perl threads with fork() for multi-host monitoring"Paul Buetow
This reverts commit 79627ce3c419a6a6d6e03c83e7c62333b60345d8.
2026-02-13Replace Perl threads with fork() for multi-host monitoringPaul Buetow
Major refactoring to fix SDL threading crashes on modern Linux with sdl12-compat. Perl threads are incompatible with SDL 1.2 compatibility layer, causing segfaults in TTF_RenderText_Solid. Changes: - Replace threads::create with fork() for process-based concurrency - Implement IPC using pipes instead of threads::shared memory - Add read_from_processes() to handle pipe-based data transfer - Update signal handling for SIGTERM and SIGUSR1 in child processes - Remove all :shared attributes from variables - Update process termination to use waitpid() instead of thread joins This allows loadbars to monitor multiple remote hosts simultaneously without SDL threading conflicts. Each host runs in its own forked process with completely separate memory space. Tested successfully with 3 remote hosts on Fedora 43. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
