What is the proper way to make user-prefs settings take effect?

[twinspop]

I am trying to to default particular roles to particular apps by including default_namespace in a user-prefs file inside the target app. This doesn't work.

How do you customize user-prefs and have it take effect?

According to user-prefs.conf.spec:

It also means that values in another app will never be used unless they are
exported globally (to system scope) or to the user-prefs app

So you need to create the meta file entry to export this setting to system. In appname/metadata/default.meta include this:

[user-prefs/role_myrole]
export = system

Your entry in user-prefs.conf:

[role_myrole]
default_namespace = appname

Will now behave as expected.
