- To the best of my ability, these are all of the Go specific formatting
- functions. If I've designed xgbgen correctly, this should be only the
- place that you change things to generate code for a new language.
-
- This file is organized as follows:
-
- * Imports and helper variables.
- * Manual type and name override maps.
- * Constants for tweaking various morphing functions.
- * Helper morphing functions.
- * Morphing functions for each "sub-unit."
- * Morphing functions for each "unit".
- * Morphing functions for collections of "units".
-
- Units can be thought of as the top-level elements in an XML protocol
- description file. Namely, structs, xidtypes, imports, enums, unions, etc.
- Collections of units are simply "all of the UNIT in the XML file."
- Sub-units can be thought of as recurring bits like struct contents (which
- is used in events, replies, requests, errors, etc.) and expression
- evaluation.
