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

[Denis Shienkov]

Hi,

1. Your function shall be in the functions.js file , e.g. in:
/yourproject/qbs/imports/YourFunctions/functions.js
2. Also your Project should have an option:

Project {
...
qbsSearchPaths: "qbs"
...
}

3. Your Product's file should contains:

...
import YourFunctions
...
...
property string gnuToolsDir: YourFunctions.findGnuToolsDir();
...

I would make it so. Also you can look how this done by analogy, e.g. in
QtCreator's sources.


BR,
Denis
