# pas2jni-3.0.4(1)

Free Pascal Java Native Interface generation tool

## NAME

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 library 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\>

- **-?**

  Show a help message.

## EXAMPLES

The following will create a file *pas/getopts.java* and a library file *getoptsjni.pas* unit from the standard getopts unit:

pas2jni units/x86\_64-linux/getopts.ppu

The following will create a file *getopts.java* and a library file *pasgetopts.pas* unit from the standard getopts unit:

pas2jni -J. -O. -Lpasgetopts -units/x86\_64-linux/getopts.ppu
