Is using '* parent="Evolution.Util"' supposed to prevent from generating bindings that depends on the one generated with this metadata ?

I have this in a gir : <virtual-method name="validate" invoker="validate"> <return-value transfer-ownership="none"> </return-value> <parameters> <parameter name="alert" transfer-ownership="none"> </parameter> </parameters> </virtual-method>

This one depends ona vapi I generated via vapigen too which start with: /* evolution-util-3.0.vapi generated by vapigen, do not modify. */

[CCode (cprefix = "E", gir_namespace = "EvolutionUtil", gir_version = "3.0", lower_case_cprefix = "e_")] namespace Evolution { namespace Util {

                    public virtual signal void response (int response_id);
            }

This vapi was generated with metadata: EvolutionUtil name="Evolution"

parent="Evolution.Util"

which is the only way I found to translate my namespace from EvolutionUtil to namespace Evolution { namespace Utl { .

Doing : /usr/local/bin/vapigen
--vapidir=.
--girdir=../e-util
--library evolution-filter-3.0
--metadatadir=.
../filter/EFilter-3.0.gir

results in:

EFilter-3.0.gir:239.69-239.69: error: The type name Evolution.Alert' could not be found <type name="EvolutionUtil.Alert" c:type="EAlert**"/> ^ EFilter-3.0.gir:249.65-249.65: error: The type name Xml.NodePtr' could not be found ^ EFilter-3.0.gir:259.65-259.65: error: The type name Xml.NodePtr' could not be found <type name="libxml2.NodePtr" c:type="xmlNodePtr"/> ^ EFilter-3.0.gir:969.69-969.69: error: The type name Evolution.Alert' could not be found ^ EFilter-3.0.gir:979.65-979.65: error: The type name Xml.NodePtr' could not be found <type name="libxml2.NodePtr" c:type="xmlNodePtr"/> ^ EFilter-3.0.gir:992.65-992.65: error: The type name Xml.NodePtr' could not be found ^ EFilter-3.0.gir:1138.69-1138.69: error: The type name Evolution.Alert' could not be found <type name="EvolutionUtil.Alert" c:type="EAlert**"/> ^ EFilter-3.0.gir:1148.65-1148.65: error: The type name Xml.NodePtr' could not be found ^ Generation failed: 8 error(s), 0 warning(s)

To sum up : the ore of the issue is that I have a gir with an argument of type name="EvolutionUtil.Alert" . I have a vapi which had namespace EvolutionUtil (this worked). I was told to use '* parent="Evolution.Util"' in the metadata to be able to have a top namespace evolution for all the evolution bindings but then vapigen complains that it cannot find "Evolution.Alert" when using vapigen against the gir which has the argument of type EvolutionUtil.Alert .

My finding seems clue me to think that vapigen properly attempt to find the Alert declaration in the vapi I generated wit the metadata '* parent="Evolution.Util'" . But then it only goes one level into the nested namespaces Evolution.Util, ie it stop at Evolution . If I hack this vapi to replace "namespace Evolution { namespace Util" by "namespace Evolution34 { namespace Util {" the error becomes : EFilter-3.0.gir:239.69-239.69: error: The type name `Evolution34.Alert' could not be found ^ Also If I remove the nested "namespace Util" the error vanish.

Is using '* parent="Evolution.Util"' supposed to prevent generating bindings against this vapi

(I am on Vala 0.14.0.20-2d9c1)

Version: 0.14.x

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information

a type is not found in a gir when using parent metadata for to generate the vapi it depens upon.
