Announcing Pegasus Frontend



  • @sam85461 never used RocketLauncher or HyperSpin personally, so not sure if I can help with that. According to their wiki you're supposed to edit the launch commands of your systems/collections (es_systems.cfg for EmulationStation). Something like this, except use %ROM% instead of [name], I think?



  • Weekly update! The themeing changes are functionally complete, I've just run into some last minute issues which take some time. As soon are they are fixed, the update is ready.

    Other than that, this week Brazilian Portuguese language was added (thanks @rutantan). Interestingly, depending on the system it might appear simply as "português" in the menu (instead of eg. "português do Brasil"). Not sure how much of an issue is that, or if that's actually what's expected. Not a bug in Pegasus itself, but I can add a workaround if it turns out to be confusing.



  • @fluffypillow I'm experiencing a strange problem loading arcade roms (both FBA and MAME) on one PC (but not another). It stems from the launcher using forward slashes in {file.path} rather than backslashes which Windows typically uses for directory paths. If I manually change the argument to be all backslashes then it will work from the command line, but that doesn't really help me with Pegasus.

    What's most strange is that it works fine on my primary PC. Either way it might make sense to change this for the windows build so it uses backslashes instead?



  • @PlayingKarrde That's certainly interesting, as according to the source code of MAME, both slashes are accepted. But other than that, yes, using backslashes on Windows sounds like a good idea.



  • Okay, after quite some time one of the largest weekly updates has landed! This is yet another breaking change, so feel free to keep an older version around if any of these changes affect you negatively.

    • Major changes in the theme Api
      • It is now possible to present games and collections in multiple locations with custom ordering and filtering
      • It is now possible to present a list of all existing games, and similarly, sort or filter it with custom parameters
      • See below for implementation details
    • Updated the 9999999 and ES2 Simple themes to these themeing changes (I should really make an updater eventually)
    • Bugfixes and optimizations
      • Fixed a bug where Pegasus crashed on exit
      • Fixed a bug where log files weren't saved properly before reboot/shutdown
      • Fixed a bug where the ES2 support could cause a crash during loading

    The bad news:

    • Custom filters support and searching/filtering in the default theme is temporarily disabled (haven't finished updating that part yet)
    • At the moment, Pegasus doesn't remember the selected game and its position in the menu when you return from playing. This will be fixed in the future, likely when theme options get added.

    Theme Api changes:

    • Previously, collection list objects and game list objects had index, current, increment/decrementIndex() fields and methods (eg. api.collections.current). Because the lists can now appear in multiple places with different sorting and filtering, having one index isn't particularly meaningful anymore, and thus all these fields and methods were removed.
    • Because the only remaining field would have been model (eg. api.collections.model), the whole intermediate object got removed, and the object itself can now be used as model (eg. api.collections).
    • These models are no longer JavaScript arrays, but so called "item models". They can be used without any difference in List/Grid/PathViews' model property. As for manual operations,
      • to get a single item, instead of themodel[anindex], you'd use themodel.get(anindex)
      • to get the count of items, instead of themodel.length, you'd use themodel.count
    • In addition, the list of all games is now accessible as api.allGames, which is a list of game objects similarly to a single collection's games field.
    • With these changes, the current data structure is:
      • api.collections is a list of collections, which is an item model
      • each collection has the same fields as before (see the Api docs)
      • each collection has a games field, a list of games, which is an item model
      • each game has the same fields and launch() method as before
      • api.allGames is a list of all games, independent of collections. Also an item model.
    • For inspriation with updating theme code, you can take a look at the different ways it's handled in the commits of ES2 Simple and 9999999-in-1. The main theme is a mess, but if you wish, you can take a look at these commits too.

    Sorting and filtering:

    • SortFilterProxyModel is now available. Take a look at the example there to see how it's used. You can find the list of sorters/filters here.
    • For example, to get the list of all games ordered by play time, you could write something like
    import SortFilterProxyModel 0.2
    
    ...
    
    SortFilterProxyModel {
        id: mysorter
        sourceModel: api.allGames
        sorters: RoleSorter { roleName: "playTime" }
    }
    
    ListView {
        model: mysorter
        ...
    }
    
    • Because filtering can now be done in themes, api.filters is now removed. In the future, it might be updated to hold the user-defined custom filters instead.


  • @fluffypillow amazing thanks for this. Been excited about these changes coming. I'll try and update my theme tomorrow if I have time.
