User language programming

The EAGLE User Language can be used to access the EAGLE and Fusion Electronics data structures and to create a wide variety of output files. To use this feature you have to write a User Language Program (ULP), and then execute it.

The following sections describe the EAGLE User Language in detail:

• Syntax lists the rules a ULP file has to follow
• Data Types defines the basic data types
• Object Types defines the EAGLE objects
• Definitions shows how to write a definition
• Operators lists the valid operators
• Expressions shows how to write expressions
• Statements defines the valid statements
• Builtins lists the builtin constants, functions etc.
• Dialogs shows how to implement a graphical front end to a ULP
