Modifying IDLdoc's output

This guide discusses how to modify the output from IDLdoc by modifying the template files (*.tt) that are provided with IDLdoc. Currently, only the templates directly documenting *.pro files (pro-file.tt), templates included by pro-file.tt (navbar.tt and tagline.tt) and objects implementing the template interface used by pro-file.tt (IDLdocRoutine and IDLdocParam) are documented for user customization. The plans is to release the documentation for other templates as they become more stable in future releases of IDLdoc.

In general, if one of the below variables is not defined/not-appropriate it will be set to '' or -1.

navbar.tt

This template is included by many other templates requiring those templates to provide the following variables:

title: title of the IDLdoc library
