VPPAPIGEN: vppapigen replacement in Python PLY.
This is a version of the VPP API generator in Python PLY. It supports
the existing language, and has a plugin architecture for generators.
Currently C and JSON are supported.
Changes:
- vl_api_version to option version = "major.minor.patch"
- enum support
- Added error checking and reporting
- import support (removed the C pre-processor)
- services (tying request/reply together)
Version:
option version = "1.0.0";
Enum:
enum colours {
RED,
BLUE = 50,
};
define foo {
vl_api_colours_t colours;
};
Services:
service {
rpc foo returns foo_reply;
rpc foo_dump returns stream foo_details;
rpc want_stats returns want_stats_reply
events ip4_counters, ip6_counters;
};
Future planned features:
- unions
- bool, text
- array support (including length)
- proto3 output plugin
- Refactor C/C++ generator as a plugin
- Refactor Java generator as a plugin
