nargo check

Checks the constraint system for errors

Usage: nargo check [OPTIONS]

Options:
  • --package <PACKAGE> — The name of the package to check

  • --workspace — Check all packages in the workspace

  • --overwrite — Force overwrite of existing files

  • --expression-width <EXPRESSION_WIDTH> — Specify the backend expression width that should be targeted

  • --bounded-codegen — Generate ACIR with the target backend expression width. The default is to generate ACIR without a bound and split expressions after code generation. Activating this flag can sometimes provide optimizations for certain programs

    Default value: false

  • --force — Force a full recompilation

  • --debug-comptime-in-file <DEBUG_COMPTIME_IN_FILE> — Enable printing results of comptime evaluation: provide a path suffix for the module to debug, e.g. "package_name/src/main.nr"

  • --skip-underconstrained-check — Flag to turn off the compiler check for under constrained values. Warning: This can improve compilation speed but can also lead to correctness errors. This check should always be run on production code
