Gantt

bop gantt — agent execution timeline

Shows horizontal bars per card run, clustered by session, with state colours and duration labels. Default output is ANSI terminal art that fills the current pane.

Quick use

bop gantt              # ANSI chart in terminal (auto-fits pane width)
bop gantt -w 80        # force 80-column width (useful in Zellij panes)
bop gantt --html       # write .cards/bop-gantt.html
bop gantt -o           # write HTML and open in browser

Output modes

ANSI mode details

• Auto-detects terminal width via ioctl(TIOCGWINSZ) — works in Zellij panes, tmux, SSH
• Falls back to $COLUMNS, then 100
• -w N overrides auto-detection
• 2-char padding per side for breathing room
• State colours use ANSI 256-colour palette
• Bars use ▓ fill blocks with matched foreground+background colour

What it shows

• Horizontal bars — one per card run, width ∝ wall-clock duration
• Clusters — runs separated by >30 min gap get their own time axis
• State colours — pending (blue), running (amber), done (green), failed (red), merged (violet)
• Duration labels — e.g. 2.7m, 4.8m next to each bar
• Stats footer — total runs, compute minutes, tokens, cost
• Legend — coloured dots with state names

Data source

Reads meta.json from every .jobcard/ in .cards/{pending,running,done,failed,merged}/. Uses runs[].started_at and runs[].ended_at for bar placement. Cards with no runs or <2s duration are excluded.

Open-ended runs (no ended_at) are capped at duration_s if available, otherwise 10 minutes.
