Right. Modules are known automatically and get pulled in via a "Depends"
item.

Correct. Or, if it is not project-specific, the qbsSearchPaths property
can go under the "preferences" part of your configuration (globally or
per profile).

Hm, yes, that seems to be missing. You could file a bug report.

Ok, good to hear.

It took me a while, but after looking at some qbs projects in the www, I got
my head around this. Please correct me if I am wrong.
Qbs modules are not a QML language feature, so the import statement is
useless here. Instead, they seem to be loaded via some magic background
functionality. For custom modules in a project, one is supposed to create a
subfolder with the following layout:
project-folder
+--subfolder e.g. 'qbs'
| +--'modules' folder
| +--folder with module-name, e.g. 'myModule'
|(name is important here)
|+--.qbs file containing the module definition
| (name does not matter)
|
+--.qbs project file which defines qbsSearchPaths : "qbs"
In the project file one would now write 'Depends { name: "myModule" }' to
load the module. Then one can access its properties as expected.
The documentation mentions 'Depends' and 'qbsSearchPaths', but the missing
link was the folder layout and naming.

Once I got modules working, the rest was easy. Module properties can be set
in a qbs profile and then accessed from within the qbs project file.

[QBS] Project configuration from within qbs profile
Hi,
I have a question regarding project configuration. A qbs project defines a
property "myProperty". I can of course set the property in the qbs file
itself and I can set the property on command line via:
qbs build myproject.qbs project.myProperty:bla
Would it also be possible to set this property in a qbs profile? That is
because I have multiple projects which should be compiled with the same
value for "myProperty".
After some investigation I guess that project-specific settings are not
supposed to go into the profile. Should I create a module for that? Is it
possible to set a module's properties in a qbs profile?
Ok, I've tried to create a module "MyModule" and access one of its
properties, but failed:
mymodule.qbs
import qbs.base 1.0
Module
{
name: "MyModule"
property string myProperty
}
myproject.qbs
import qbs.base 1.0
import "mymodule.qbs" as MyModule
Product {
// ...
Depends { name: "MyModule" }
property string productProperty: MyModule.myProperty
// ...
}
This results in : myproject.qbs:4:1 Product dependency 'MyModule' not found.
I've also tried to create a subfolder and load the module from there as it
has been advised in the QML documentation, without luck. Maybe I make a
general mistake here. These are my first steps with qbs and QML so I'm not
too familiar with the module concept, yet.
Thanks
Richard
