A CLI tool to colorize and filter piped input. Good for large tests (like monorepos) when you want to focus on results not boilerplate.

brew tap xopo/filter
brew install filter

• PASS → green
• FAIL → red
• failed/passed summary → highlighted
• Custom watch words → yellow bold (default: expected, received)

some_test_command | filter

some_test_command | filter -w "error,warn,timeout"

echo "got expected value" | filter -w expected

• Input via stdin (not TTY)
• Pipe or redirect output into the tool
