File filters

You can filter any file bassed on a globbing pattern as you may now from your own computer file system:

Examples:

A specific file:

# this rule applies to exactly one file:
- action: validate
- file: example-patient.json

All xml files; make sure that all xml examples have a profile field:

- predicate: meta.profile.exists()
  files: example/*.xml

Globbing

WIth globbing you can use a double star ** to define any sequence of subdirectories. This example

  /**/example.xml 

will include

  main\example.xml
  main\sub\example.xml
  main\sub\sub\example.xml

Multiple file filters

The files filter also allows you to define multiple filters.

- action: validate
  files: 
     - /*.json
     - /*.xml

Excluding files

When you want to exclude a pattern, just use an exclamation mark. If you want to exclude package.json from the example above, write it like the following. You have to add quotes, or YAML will get confused:

- action: validate
  files: 
     - /*.json
     - "!package.json" 
     - /*.xml
