[QBS] Functions in QBS scripts and accessing properties from them.

[Denis Shienkov]

E.g. IMHO, in your case should be like this:


= myproject/myproject.qbs =

import qbs 1.0

Project {
    qbsSearchPaths: "qbs"

    references: [
        "app/app.qbs",
    ]
}


= myproject/qbs/imports/MyFunctions/functions.js =

function findGnuToolsDir()
{
...
}


= myproject/app/app.qbs =

import qbs.base 1.0
import MyFunctions

Application {
    name: "myapplication"
    ...
    ...
    property string gnuToolsDir: YourFunctions.findGnuToolsDir();
    ...
    ...

}

But, if to be honest, I do not know how to do it by other way (I even do
not trying do check other way). :)

BR,
Denis
