A lot of configuration elements rely on regular expressions. The most prominent examples are the useful includes and excludes elements. All of these regular expressions use the Java java.util.regex.Pattern API, with all of its features. The Pattern API allows for specifying flags and for your configuration convenience, the applied flags are, by default:
-
COMMENTS: This allows for embedding comments (and, as a side-effect: meaningless whitespace) in regular expressions, which makes them much more readable. -
CASE_INSENSITIVE: Most schemas are case insensitive, so case-sensitive regular expressions are a bit of a pain, especially in multi-vendor setups, where databases like PostgreSQL (mostly lower case) and Oracle (mostly UPPER CASE) need to be supported simultaneously.
But of course, this default setting may get in your way, for instance if you rely on case sensitive identifiers and whitespace in identifiers a lot, it might be better for you to turn off the above defaults:
<configuration>
<generator>
<database>
<regexFlags>COMMENTS DOTALL</regexFlags>
</database>
</generator>
</configuration>
See the configuration XSD, standalone code generation, and maven code generation for more details.

All the flags available from java.util.regex.Pattern are available as a whitespace-separated list in standalone XML, or a comma separated list in Maven.
