CLI Basics

The opql binary is a thin wrapper around the runner crate. It currently exposes a single entry point, --run, that executes a PQL string and writes the result to stdout.

Usage

opql --run "<PQL query>"

Example:

opql --run "select equity from hero='AA', villain='KK', board='AhKh2c', game='holdem'"

Notes

• Quote the full query with double quotes so the shell passes it as one argument.
• Use single quotes inside the query for hand, range, and board literals.
• Errors in parsing or evaluation are written to stderr; successful results go to stdout.

Getting Help

For richer workflows — batching queries, scripting with results, custom trial counts — use the library API directly.
