#147 What do you think?

[anakhalil]

I am working on try to pass an optional argument that will be evaluated. i.e. errMessage: "'$fqdn' is invalid." which would print as: -host.test.com is invalid

[anakhalil]

The message can look like: ''$value' is incorrect $value will be replaced by the instance data. I need to make a change so that it will use path and resolve $value rather then just substituting err.instance.

One issue is that top level properties will return all instance data, if $value is used within the custom error message.

Going to leave it here until I get some feedback. Its quite simple now. If the custom message (value of errMessage) contains $iData then it will replace $iData with instance data.

Of course there are some limitations to this:

• it will replace all occurrences of $iData (can limit this with count)
• you can no longer use $iData in the message
• if the instance data is top level then it will print all instance data

Use cases:

hosts:
  type: string
  pattern: -regex-
  errMessage: "'$iData' does not match the regex pattern. Please see the docs"

Will print: FAIL ...... 'bad*host*' does not match the regex pattern. Please see the docs ...

or

hosts:
  type: string
  pattern: -regex-
  errMessage: "Config has bad host. Please see the docs"

Will print: FAIL ...... Config has bad host. Please see the docs ...
