NOTES

DEPENDENCIES

No external dependencies outside Perl's standard distribution.

FUNCTIONS

No functions are automatically exported to the calling namespace.

assert( \%env, \%want, \%params )

Ensure your environment, parameter env (hashref), matches with the environment description, parameter want (hashref). Use parameter params (hashref) to specify processing options.

Supported params:

break_at_first_error

Verify environment only up until the first error. Then break and return with only that error.

Return: hashref: { success => 1/0, errors => hashref, };

report_errors( \%errors )

Report errors in a nicely formatted way.

file_to_desc( @rows )

Extract an environment description from a .envdesc file.
