In addition to the built-in Jinja filters listed here, the following additional features are implemented in the ivigenerator.

return_type(symbol)

Returns the C++ type for the passed symbol.

E.g. QString for a symbol of type "string".

parameter_type(symbol)

Return the C++ type for the passed symbol. This returns the same type as return_type(), but already prepared to be used as a parameter for methods.

E.g. "const QString &<name>" for a symbol of type "string"

getter_name(symbol)

Returns the getter name of the property, if defined by the @getter_name annotation. Otherwise retuns the passed symbol.

setter_name(symbol)

Returns the setter name of the property, if defined by the @setter_name annotation. Otherwise retuns the passed symbol.

default_type_value(symbol)

Returns the default value for the passed symbol. Models are initialized as nullptr

default_value(symbol, zone="=")

Returns the default value for the passed symbol set by the @default annotation. If not set uses default_type_value instead.

The zone parameter is used to identify different default values per zone.

model_type(symbol)

Returns the C++ class name for this model.

flag_type(symbol)

Returns the name defined by the @type annotation for the passed flag. If this is not set, tries to pluralize the passed name by adding an 's' at the end.

parse_doc(string)

Parses the passed comment string and adds every javadoc command into its own group. Sentences without tag are put into the 'description' group.

{% with doc = comments|parse_doc -%}
{% if doc.brief %}    \brief {{doc.brief}}
{% endif %}

{% if doc.description %}
    {{doc.description}}
{% endif %}
{% endwith %}

lowerfirst(string)

Only lowers the first character of the given string.

range_low(property)

Returns the minimum value for the passed property using the @range or @minimum annotations.

range_high(property)

Returns the maximum value for the passed property using the @range or @maximum annotations.

strip_QT(string)

Removes the 'QT' at the beginning, if the string starts with it.

domain_values(symbol)

Returns the domain values for the passed property using the @domain annotation.

enum_value(value, module_name)

Returns the fully qualified C++ name of the given value. The passed module_name is used as C++ class name containing the enum.

Also supports passing '|' connected values.

tag_by_path(symbol, path, default_value=False)

Find the tag given by its full path in the object hierarchy, like property.config_sim.zones.right. If some parts of the path are missing, return None.

conf_sim_tag(symbol, path, default_value=False)

Find the tag, given by its path, located under the "config_simulator" sub-object. Returns None, if parts of the path are missing.

jsonify(obj)

Returns a JSON representation of the given obj.

has_domains(properties)

Returns true if any of the given properties has @range or @domain annotations.

json_domain(properties)

Returns the property domains for the given properties formated in JSON.

qml_type(interface)

Returns the name of the interface for use in QML. This name is defined by the @qml_type annotation. This annotation is optional: if not provided, the interface name is used.

qml_control(symbol, backend_obj)

Returns the QML code for the control (or group of controls) to represent the editing UI for the passed symbol.

qml_binding_property(symbol)

Returns the name of the property of the QML control to be bound with.

E.g. "value" for a Slider and "checked" for a CheckBox.

qml_control_signal_parameters(symbol)

Returns the parameters for calling the signal using the values from the UI controls.

struct_includes(symbol)

Returns the includes for the structs that the interface or a struct depends on. The returned strings are complete and in format #include "struct.h".
