* Available configuration keys:
* - source: The input value - either a scalar or an array.
- * - map: An array (of 1 or more dimensions) that identifies the mapping between
+ * - map: An array (of 1 or more dimensions) that defines the mapping between
* source values and destination values.
* - bypass: (optional) Whether the plugin should proceed when the source is not
- * found in the map array. Defaults to FALSE.
+ * found in the map array, defaults to FALSE.
* - TRUE: Return the unmodified input value, or another default value, if one
* is specified.
* - FALSE: Throw a MigrateSkipRowException.
*
* Examples:
*
+ * If the value of the source property 'foo' is 'from' then the value of the
+ * destination property bar will be 'to'. Similarly 'this' becomes 'that'.
* @code
* process:
* bar:
* this: that
* @endcode
*
- * If the value of the source property foo was "from" then the value of the
- * destination property bar will be "to". Similarly "this" becomes "that".
- * static_map can do a lot more than this: it supports a list of source
- * properties. This is super useful in module-delta to machine name conversions.
- *
+ * The static_map process plugin supports a list of source properties. This is
+ * useful in module-delta to machine name conversions. In the example below,
+ * value 'filter_url' is returned if the source property 'module' is 'filter'
+ * and the source property 'delta' is '2'.
* @code
* process:
* id:
* plugin: static_map
- * source:
- * - module
- * - delta
- * map:
- * filter:
- * 0: filter_html_escape
- * 1: filter_autop
- * 2: filter_url
- * 3: filter_htmlcorrector
- * 4: filter_html_escape
- * php:
- * 0: php_code
+ * source:
+ * - module
+ * - delta
+ * map:
+ * filter:
+ * 0: filter_html_escape
+ * 1: filter_autop
+ * 2: filter_url
+ * 3: filter_htmlcorrector
+ * 4: filter_html_escape
+ * php:
+ * 0: php_code
* @endcode
*
- * If the value of the source properties module and delta are "filter" and "2"
- * respectively, then the returned value will be "filter_url". By default, if a
- * value is not found in the map, an exception is thrown.

- * When static_map is used to just rename a few things and leave the others, a
- * "bypass: true" option can be added. In this case, the source value is used

- *
+ * When static_map is used to just rename a few values and leave the others
+ * unchanged, a 'bypass: true' option can be used. See the example below. If the
+ * value of the source property 'foo' is 'from', 'to' will be returned. If the
+ * value of the source property 'foo' is 'another' (a value that is not in the
+ * map), 'another' will be returned unchanged.
* @code
* process:
* bar:
* plugin: static_map
* source: foo
- * map:
- * from: to
- * this: that
- * bypass: TRUE
+ * map:
+ * from: to
+ * this: that
+ * bypass: TRUE
* @endcode
*
- * If the value of the source property "foo" is "from" then the returned value
- * will be "to", but if the value of "foo" is "another" (a value that is not in
- * the map) then the source value is used unchanged so the returned value will
- * be "from" because "bypass" is set to TRUE.
+ * A default value can be defined for all values that are not included in the
+ * map. See the example below. If the value of the source property 'foo' is
+ * 'yet_another' (a value that is not in the map), 'bar' will be returned.
+ * @code
+ * process:
+ * bar:
+ * plugin: static_map
+ * source: foo
+ * map:
+ * from: to
+ * this: that
+ * default_value: bar
+ * @endcode
*
+ * If your source data has boolean values as strings, you need to use single
+ * quotes in the map. See the example below.
* @code
* process:
* bar:
* plugin: static_map
* source: foo
- * map:
- * from: to
- * this: that
- * default_value: bar
+ * map:
+ * 'TRUE': to
* @endcode
*
- * If the value of the source property "foo" is "yet_another" (a value that is
- * not in the map) then the default_value is used so the returned value will
- * be "bar".
+ * Mapping from a string which contains a period is not supported. A custom
+ * process plugin can be written to handle this kind of a transformation.
+ * Another option which may be feasible in certain use cases is to first pass
+ * the value through the machine_name process plugin.
