Tmux Status Debug

Capture with control chars visible

tmux capture-pane -t "main:1" -p -S -30 | cat -v | tail -40

Check if pattern exists in pane

tmux capture-pane -t "main:1" -p -S -20 | grep -o "pattern"

Debug Script

Create /tmp/debug_status.py and run with the Nix Python that has libtmux:

import sys
sys.path.insert(0, "/Users/emiller/.config/dotfiles/packages/tmux-opencode-integrated/scripts")
import smart_name
import re

import libtmux
server = libtmux.Server()
for session in server.sessions:
    for window in session.windows:
        for pane in window.panes:
            program = smart_name.get_pane_program(pane)
            if program in smart_name.AGENT_PROGRAMS:
                print(f"\n=== {program} in {session.name}:{window.name} ===")
                try:
                    cmd_output = pane.cmd("capture-pane", "-p", "-S", "-20").stdout
                    if isinstance(cmd_output, list):
                        content = "\n".join(cmd_output)
                    else:
                        content = str(cmd_output)

                    cleaned = smart_name.strip_ansi_and_control(content)
                    print(f"Last 300 chars (cleaned):\n{cleaned[-300:]}")
                    print(f"\n--- Status: {smart_name.get_opencode_status(pane)} ---")
                except Exception as e:
                    print(f"Error: {e}")

Find the Nix Python with libtmux

# Build the package and get the store path
nix build .#tmux-opencode-integrated --no-link --print-out-paths

# Check wrapper to find Python path
head -10 /nix/store/<hash>-tmux-opencode-integrated-*/share/tmux-plugins/tmux-opencode-integrated/scripts/smart-name.sh

# Run debug script with that Python
/nix/store/<python-hash>-python3-*-env/bin/python3 /tmp/debug_status.py

Pattern Testing

Test patterns against sample content:

import re

content = """ctrl+t variants  tab agents  ctrl+p commands    • OpenCode 1.1.30"""

patterns = [
    (r"OpenCode \d+\.\d+\.\d+", "IDLE - version"),
    (r"ctrl\+p commands", "IDLE - status bar"),
    (r"esc interrupt", "BUSY - can interrupt"),
    (r"Esc to cancel", "BUSY - can cancel"),
    (r"■■■", "BUSY - progress bar"),
]

for pattern, desc in patterns:
    if re.search(pattern, content, re.IGNORECASE):
        print(f"✓ {desc}: {pattern}")

Status Priority

Order matters - first match wins:

1. ERROR - Traceback, panic, FATAL ERROR, API errors
2. WAITING - Allow once?, Permission required, yes/no/skip prompts
3. BUSY - Thinking..., spinners, Running tools, esc interrupt
4. IDLE - Input prompt, context display, OpenCode version, ctrl+p commands
5. UNKNOWN - No patterns matched (fallback)

Adding New Patterns

1. Capture real pane content with the debug script above
2. Identify unique text that indicates the state
3. Add pattern to appropriate list in smart_name.py
4. Add test case in tests/test_smart_name.py
5. Run tests: uvx pytest tests/test_smart_name.py -v
6. Rebuild: nix build .#tmux-opencode-integrated

Common Issues

"No module named 'libtmux'"

Using wrong Python. Must use the Nix-wrapped Python from the package.

Patterns not matching

Terminal control characters may be interfering. The strip_ansi_and_control() function should handle this, but check with cat -v to see raw content.

Status showing ERROR when it shouldn't

Check if content contains error-like strings from previous output. The detection looks at last 20 lines of pane content.
