The old code was legal, and the things it did worked in other places, so should have worked here, too.
Hopefully just rearranging stuff convinces what I assume to be a compiler bug to not happen.
This one's a biggie.
The basic idea's that GameSettings should know:
* what the interpreted value of a setting is, so it can actually be used.
* what the original value the user put in their config was, so it can be put back when the config's saved.
* which path it's processing the openmw.cfg from so relative paths can be resolved correctly.
* whether a setting's a user setting that can be modified, or from one of the other openmw.cfg files that can't necessarily be modified.
This had fairly wide-reaching implications.
The first is that paths are resolved properly in cases where they previously wouldn't have been.
Without this commit, if the launcher saw a relative path in an openmw.cfg, it'd be resolved relative to the process' working directory (which we always set to the binary directory for reasons I won't get into).
That's not what the engine does, so is bad.
It's also not something a user's likely to suspect.
This mess is no longer a problem as paths are resolved correctly when they're loaded instead of on demand when they're used by whatever uses them.
Another problem was that if paths used slugs like ?userconfig? would be written back to openmw.cfg with the slugs replaced, which defeats the object of using the slugs.
This is also fixed.
Tracking which settings are user settings and which are in a non-editable openmw.cfg allows the launcher to grey out rows so they can't be edited (which is sensible as they can't be edited on-disk) while still being aware of content files that are provided by non-user data directories etc.
This is done in a pretty straightforward way for the data directories and fallback-archives, as those bits of UI are basic, but it's more complicated for content files as that uses a nmodel/view approach and has a lot more moving parts.
Thankfully, I'd already implemented that when dealing with builtin.omwscripts, so it just needed wiring up.
One more thing of note is that I made the SettingValue struct storable as a QVariant so it could be attached to the UI widgets as userdata, and then I could just grab the original representation and use it instead of needing any complicated mapping from display value to on-disk value.
1 with the data directories
2 with the BSA archives
3 with the content selector
When user select a directory to be added, first we walk the directory
hierarchy to make a list of all potential data= entries. If we find
none, the selected directory is added.
If more than one data directory is found, user is presented with a
directory list to check which one(s) are to be added.
Directories containing one or more content file are marked with an icon.
data= and fallback-archive= lines are handled like content= lines:
- they are part of the profile in launcher.cfg, prefixed by the profile
name
- they are updated in openmw.cfg when profile is selected / created
Directories can be moved in the list by drag and drop or by buttons.
Insertion is possible anywhere in the list.
Global data path and data local are shown but are greyed out, as they
are always included.
No attempt is made to ensure that the user choice are valid
(dependencies, overwrite of content).
After a profile is loaded, any added content is highlighted in green.
