What is docbook-lint ?

docbook-lint is a tool to check DocBook XML files for various problems.

Most DocBook toolchains only check for well-formedness of the XML and validity against a DTD. But there are many other kinds of useful, automated tests that you could do to a DocBook file, and that's where docbook-lint comes in.

So far it checks for the following:

  • overly long lines within <screen> elements
  • overly long content within <computeroutput> elements
  • spelling mistakes, with intelligent handling of language, and suppression of spellchecking within e.g. textual screen dumps, code fragments etc
  • presence of "forbidden" words (e.g. for swearwords or trademarks), based on a user-supplied configuration file
  • naming conventions for IDs within the document

Ideas and patches for other tests most welcome! Please file them in this Trac instance.
