class NamingConvention(BaseNamingConvention)

[view_source]

Case insensitive naming convention, converting source identifiers into lower case snake case with reduced alphabet.

• Spaces around identifier are trimmed
• Removes all ascii characters except ascii alphanumerics and underscores
• Prepends _ if name starts with number.
• Multiples of _ are converted into single _.
• Replaces all trailing _ with x
• Replaces + and * with x, - with _, @ with a and | with l

Uses __ as patent-child separator for tables and flattened column names.
