## 12 Language Filters

Please note: This chapter is probably completely outdated!

This chapter discusses the language filter support in Form Designer, targeted primarily to the developers of bindings to other language. As of this writing, the authors are aware of the following bindings

`ada95`

  by G. Vincent Castellano gvc@ocsystems.com

`perl`

  by Martin Bartlett martin@nitram.demon.co.uk

`Fortran`

  by G. Groten zdv017@zam212.zam.kfa-juelich.de and Anke Haeming A.Haeming@kfa-juelich.de

`pascal`

  by Michael Van Canneyt michael@tfdec1.fys.kuleuven.ac.be

`scm/guile`

  by Johannes Leveling Johannes.Leveling@Informatik.Uni-Oldenburg.DE

`python`

  by Roberto Alsina ralsina@ultra7.unl.edu.ar. It would appear that author of python binding is no longer working on it.

These bindings are of varying degree of beta-ness and support. It appears to the authors that the most convenient and flexible way of getting output in the targeted language is through external filters that are invoked transparently by fdesign. This way, developers of the binding would have complete control over the translation of the default output from the fdesign to the target language and at the same time have the translation done transparently.
