[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 01/22] golang/xenlight: generate enum types from IDL
From: Nick Rosbrook <rosbrookn@xxxxxxxxxxxx>
Introduce gengotypes.py to generate Go code the from IDL. As a first step,
implement 'enum' type generation.
As a result of the newly-generated code, remove the existing, and now
conflicting definitions in xenlight.go. In the case of the Error type,
rename the slice 'errors' to 'libxlErrors' so that it does not conflict
with the standard library package 'errors.' And, negate the values used
in 'libxlErrors' since the generated error values are negative.
Signed-off-by: Nick Rosbrook <rosbrookn@xxxxxxxxxxxx>
---
Changes in v2:
- Introduce Makefile targets for code generation
- Re-generate Go code (includes new libxl_passtrhough enum).
- Use *.gen.go naming convention for generated Go files.
