Tools

Validators, compilers and translators

• The latest version of libsmi contains a YANG output driver for the smidump tool. It generates YANG modules from SMI/SMIv2 MIBs.

• The webinterface to smidump now supports YANG output.

• pyang (manual page) is an extensible YANG validator written in Python. It can be used standalone as a validator of YANG modules, or to generate YIN, YANG, DSDL and XSD from YANG and YIN. It can also be integrated in other applications, which can, for example, generate vendor-specific stub code. Validation of instance XML documents (datastore contents or NETCONF PDUs) using pyang is explained in DSDLMappingTutorial and yang2dsdl manual page.

• pyang can also be used to generate UML diagrams from YANG data models. See UML Output Example.

• There is a webinterface to pyang available.

• yangdump is a YANG validator and translator, available at http://www.netconfcentral.com/.

• There is a webinterface to yangdump available.

• jYang is a YANG validator and translator written in Java.

• pyangbind is a pyang plugin to generate Python class hierarchy from YANG module

• goyang is a YANG parser and compiler for Go programs

YANG Editing tools

• yang-mode.el is an emacs mode for editing YANG files. RFC 6020 compliant. Requires cc-mode 5.30 or later.
  NOTE With emacs 23, you need to do (for details, see the comment in the file):
  • In .emacs, use autoload instead of require (autoload 'yang-mode "yang-mode" "Major mode for editing YANG models." t)
  • Possibly delete cc-mode.elc

• yang.vim is a VIM syntax file for editing YANG files. RFC 6020 compliant.

• There is an opensource Eclipse plugin for YANG available from https://github.com/xored/yang-ide/wiki/Installing.

• YANG-IDE is a integrated development environment for YANG, using Eclipse.

• YANG design studio is an Eclipse plugin to edit, visualize, and compile YANG modules

• n++yang.xml is a Notepad PLus syntax file for editing YANG files.

YANG and NETCONF clients and servers

• yangcli-pro is a free YANG-based NETCONF client.

• ConfD Basic is a free YANG-based NETCONF server.

Other tools

• rfcstrip is a program that extracts YANG modules, MIB modules, and other marked code components from RFCs and Internet-Drafts.

• xym is another tool to extract YANG models from RFCs.

• RELAX NG schema for YIN
  • yin.rng: XML syntax
  • yin.rnc: compact syntax
  • yin.html: Annotated XML syntax with cross-references
