pas2jni — Free Pascal Java Native Interface generation tool

Synopsis

pas2jni [options] <unit> [<unit2> <unit3> ...]

Generate a Java native interface description and library from compiled Free Pascal units. pas2jni generates per unit 2 files: a library that provides access to the functions and procedures in the pascal unit in a manner that Java understands, and a .java file that describes the library, and can be used to access the libary from Java.

Options

-U<path>
Unit search path, semicolon delimited. Wildcards are allowed.
-L<name>
Set output library name. By default, this is the name of the unit followed by 'jni'.
-P<name>
Set Java package name. This is by default 'pas'.
-O<path>
Set output path for Pascal files. This is the current directory, by default.
-J<path>
Set output path for Java files. By default, this is 'pas'.
-D<prog>
Set full path to the "ppudump" program. The ppudump program is needed to analyse the contents of the unit files.
-I<list>
Include the list of specified objects in the output. The list is semicolon delimited. To read this list from a file use -I@<file>
-E <list>
Exclude the list of specified objects from the output. The list is semicolon delimited. To read this list from a file use -E@<file>
