# known_errors is a dictionary of errors from validation that we want to give users a hint for solving their problem.
|
|
# The key is the known error, or part of the known error. It is a string.
|
|
# We use the key to see if we have a known error.
|
|
# The value is a dictionary that contains the hint for the user.
|
|
|
|
# If we want to capture details about the error we can use a regex for the key.

# If you use a regex, you must add a groups entry to the value dictionary.

# groups is a dictionary defining the values returned from the groups() method from the regex search.
|

# They key is the string used as a placeholder in the hint, and the value is the groups index.

# I know this explanation is confusing. If you have ideas for clarification, pull request welcome.
