2018-01-23	VPPAPIGEN: vppapigen replacement in Python PLY.	Ole Troan	1	-2/+2
	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 Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>
2017-10-09	vppapigen: support per-file (major,minor,patch) version stamps	Dave Barach	1	-0/+2
	Add one of these statements to foo.api: vl_api_version 1.2.3 to generate a version tuple stanza in foo.api.h: /**** Version tuple ***/ vl_api_version_tuple(foo, 1, 2, 3) Change-Id: Ic514439e4677999daa8463a94f948f76b132ff15 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Ole Troan <ot@cisco.com>
