Exit codes

The ty command line interface uses the following exit codes:

Exit code	Description
0	no violations with severity error or higher were found
1	violations with severity error or higher were found
2	invalid CLI options, invalid configuration, or IO errors
101	internal error

ty supports two command line arguments that change how exit codes work:

• --exit-zero: ty will exit with 0 even if violations were found.
• --error-on-warning: ty will exit with 1 if it finds any violations with severity warning or higher.
