Kwalify schema for data structures

## NAME

pkwalify - Kwalify schema for data structures

## SYNOPSIS

```
    pkwalify [-v] [-s] [-m parse-mod] -f schemafile datafile
```

## DESCRIPTION

**pkwalify** validates the data from *datafile* (which may be a YAML or JSON file) against a schema defined with *schemafile* (which also may be a YAML or JSON file).

It is required that either YAML, YAML::XS or YAML::Syck is installed to parse YAML files, or either JSON or JSON::XS for JSON files. Or the module specified on the command-line.

The program returns the number of errors found in the datafile. An exit status 0 means no errors.

### OPTIONS

- \-f *schemafile*

  Specify a schema file, either as YAML or JSON. Required.

- \-m *parse-mod*

  Specify the YAML or JSON Perl module to use. Valid modules are: YAML, YAML::XS, YAML::Syck, JSON and JSON::XS.

- \-s

  Be silent if the document is valid.

- \-v

  Show script and module versions and exit.

- \-h --help

  Show summary of options.
