# Scanner

Creates custom dependency scanners in modules. More...

- List of all members, including inherited members

## Properties

- condition : bool
- inputs : stringList
- recursive : bool
- scan : script
- searchPaths : script

## Detailed Description

A Scanner item can appear inside a Module item, and allows to extract dependencies for artifacts from the artifacts' file contents. For example, this is what a scanner for "qrc" files might look like:

     import qbs.Xml

     Module {
       Scanner {
         inputs: 'qrc'
         scan: {
           var xml = new Xml.DomDocument(input.filePath);
           dependencies = [];
           // retrieve <file> entries from the XML document
           return dependencies;
         }
       }
     }

## Property Documentation

condition : bool

If `true`, the scanner is enabled, otherwise it does nothing.

Default: `true`

inputs : stringList

A list of file tags the input artifacts must match.

Default: Undefined

recursive : bool

Determines whether to scan the returned dependencies using the same scanner.

Default: `false`

scan : script

A script that reads the input artifact and returns a string list with dependencies.

The code in this script is treated as a function with the signature `function(project, product, input, filePath)`, where `input` is the artifact at which the scan originated, and `filePath` is the currently scanned file. For non-recursive scans, `filePath` is always equal to `input.filePath`.

Default: Undefined

searchPaths : script

A script that returns the paths where to look for dependencies.

The code in this script is treated as a function with the signature `function(project, product, input)`.

Default: Undefined
