# FileTagger Item

This item maps file patterns to tags. It can be attached to a product or a module. In the latter case, its effect is the same as if it had been attached to all products having a dependency on the respective module. For instance, the cpp module of Qbs has, among others, the following file tagger:

      FileTagger {
          patterns: "*.cpp"
          fileTags: ["cpp"]
      }

As a result, the "cpp" tag is automatically attached to all files ending with ".cpp" in products depending on the cpp module. This causes them to be compiled, because a C++ compiler rule has "cpp" in its list of matching input tags.

File taggers are disabled if file tags are set explicitly in a product or group. For example, the "cpp" tag is not attached to the cpp files in the following product:

      Product {
          Depends { name: "cpp" }
          Group {
              files: "*.cpp"
              fileTags: "other"
          }
      }

## FileTagger Properties

Property | Type | Default | Description
--- | --- | --- | ---
patterns | stringList | none | The patterns to match against. Supports the usual wildcards '*', '?' and '[]'. Neither the list itself nor any of its elements may be empty.
fileTags | list | empty list | Tags to attach to a product's files. These can then be matched by a rule.
