2016-12-02Python API: Support for per message CRC and API split.Ole Troan1-1/+1
These changes are incompatible with Python VPP API 1.2 There is now a new VPP Class and it can be used like: from vpp_papi import VPP jsonfiles = [] for root, dirnames, filenames in os.walk('../../../build-root/'): if root.find('install-') == -1: continue for filename in fnmatch.filter(filenames, '*.api.json'): jsonfiles.append(os.path.join(root, filename)) vpp = VPP(jsonfiles) rv = vpp.show_version() print('RV', rv.program.decode().rstrip('\0x00')) vpp.disconnect() Change-Id: Ic92d226de2cf3626e750404012247e7fc24fb7fc Signed-off-by: Ole Troan <ot@cisco.com>
2016-09-27Fix import line for setup.pyPeter Ginchev1-2/+2
Build fails in case python-setuptools is not installed. Change-Id: I1611f3560db82a4a48c51a9f614a813a9a540698 Signed-off-by: Peter Ginchev <pginchev@cisco.com>
2016-09-23Python API: Preparation for RPM/DEB packaging.Ole Troan1-6/+24
Recheck. Repackage the Python API binding to include all necessary modules in a single Python package. Change-Id: I5e35141d413bfb1aad650217e1ca07d85646c349 Signed-off-by: Ole Troan <ot@cisco.com>
2016-08-25VPP Python language binding - plugin supportOle Troan1-12/+7
- Moved Python generator tool to tools directory - Added build-vpp-api Makefile target - Generator now only creates a Python representation of the .api the rest of the framework is in the vpp_papi script - Each plugin has its own namespace. - Plugin Python files are installed in vpp_papi_plugins for easy use inside the build tree.
