widlproc can be used to validate WebIDL in W3C specifications. It serves as the basis for the W3C Web IDL on-line checker.

widlproc's generated XML is used to generate webinos JavaScript APIs specifications.


widlproc is licensed under the Apache 2 License.


See also webidl.js, a JavaScript-based Web IDL parser used by various tools in W3C.


Most of the work on widlproc was done by Tim Renouf and Paddy Byers. Aplix corporation owns the copyright of the code up to June 2011.

The tool is kept up to date with the changes in the spec by Dominique Hazael-Massieux, through funding from the webinos project since June 2011.
