Apache FreeMarker Generator CLI
provides multiple ways to pass configuration data used in in templates
User-supplied system properties are added to the JVM's system properties
> freemarker-generator -Dfoo1=foo1 -D foo2=foo2 -t freemarker-generator/info.ftl
User-supplied parameters allow to pass additional information to an Apache FreeMarker template
-Pname=value
to define a key/value pair-Pname:group=value
to define a map containing key/value pairs, i.e nested mapPass a simple name/value pair on the command line
> freemarker-generator -t freemarker-generator/info.ftl -P key=value User Supplied Parameters ------------------------------------------------------------------------------ - key ==> value
By providing a group
you can create nested maps
> freemarker-generator -t freemarker-generator/info.ftl -P foo1:group=bar1 -P foo2:group=bar2 User Supplied Parameters ------------------------------------------------------------------------------ - group ==> { foo1=bar1 foo2=bar2 }
It is also possible to mix and match the two approaches
> freemarker-generator -t freemarker-generator/info.ftl -P foo1:group=bar1 -P foo2:group=bar2 -P key=value User Supplied Parameters ------------------------------------------------------------------------------ - key ==> value - group ==> { foo1=bar1 foo2=bar2 }
