Inspection Module

This XQuery Module contains functions for generating xqDoc files from XQuery modules.

Introduction

xqDoc provides a simple vendor neutral solution for generating a documentation from XQuery modules. The documentation conventions have been inspired by the JavaDoc standard. Documentation comments begin with (:~ and end with :), and tags start with @. xqDoc comments can be specified for main and library modules and variable and function declarations. We have slightly extended the conventions and updated the xqDoc schema:

• an <xqdoc:namespaces/> node lists all namespaces of a module
• if annotations are attached to variables or functions, an <xqdoc:annotations/> node is added
• variables now have a name and a type.

An example is shown below.

Conventions

All functions in this module are assigned to the http://basex.org/modules/xqdoc namespace, which is statically bound to the xqdoc prefix.
All errors are assigned to the http://basex.org/errors namespace, which is statically bound to the bxerr prefix.

Functions

xqdoc:parse

Signatures	xqdoc:parse($input as xs:string) as element(xqdoc:xqdoc)
Summary	Parses the specified $input and generates an xqDoc element.

Example

The query xqdoc:parse('sample.xq')} will convert the following example module...

(:~ 
 : This module provides some sample functions to demonstrate
 : the features of the XQDoc Module.
 : @author BaseX Team
 : @see http://docs.basex.org/wiki/XQDoc_Module
 : @version 1.0
 :)
module namespace samples = 'http://basex.org/modules/samples';

(:~ This is a sample string. :)
declare variable $samples:test-string
  as xs:string := 'this is a string';

(:~
 : This function simply returns the specified integer.
 : @param $number number to return
 : @return specified number
 :)
declare %private function samples:same(
  $number as xs:integer
) as xs:integer {
  $number
};

...to the following output:
