I want to put some code together in a local library that is then used by several other projects. I am running into a few problems. Firstly when I try and configure the code to be a library (dub init, add d files to source, and remove source/app.d - perhaps this wrong) dub test no longer seems to work?
Secondly I am having problems getting dub to add the library code to other projects. It seems to work if I run dub add-local path/to/library and then add the appropriate dependencies to the projects dub.json file. However, I didn't manage to find documentation that explains exactly how this should work. Also there seems to be some mention getting this to work with versions (in the documentation about dub add-path), which I couldn't follow.
Does anyone know in more detail how this works or how I can find out?
You need to add 2 configurations. The first configuration is used automatically when you execute dub build. Just name the config debug with targetType library. Add a second configuration with name unittest and targetType executable and attribute mainSourceFile pointing to a module containing your main function for your test. For example name this module testapp.d.
The module testapp.d you need to exclude in your configuration debug using attribute excludeSourceFiles.
The configuration unittest is automatically used when you execute dub test.
Kind regards

Thank you very much. In case someone wants more specific instructions:
(a) add a file source/test.d containing:
void main(){}
(b) add configurations to dub.json:
"configurations": [
{ "name": "debug",
"excludedSourceFiles": ["source/test.d"],
"targetType": "library"},
{ "name": "unittest",
"mainSourceFile": "source/test.d",
"targetType": "executable"}]
This still leaves open the question of how to include a version of such a library in another project via dub.
