Mudlet 3.12 – autocompletion in editor

Code faster with the autocomplete feature. Annoying bugs & crashes fixed.

New feature - automatic word completion

In our ongoing efforts to make coding even more pleasant in Mudlet's new editor since version 3.3 one year ago, we are proud to present autocomplete! While you are still typing, you can now choose directly from the appearing list of suggested commands.

Autocomplete in action

There is still a lot of room for improvement here, for example suggestions do not yet include all lua functions and especially "combined" commands like string.findPattern or Geyser.Container:new. However we feel this will help you speed up a lot already, so it is well worth releasing.

Thanks to dicene for adding this in!


Profiles will now autoload their server encodings correctly (thanks SlySven). The "Save Profile As" button and the package exporter work again as expected (thanks vadi2). Module sync will now also work correctly, even if the original zip was deleted.

New feature for Geyser

Geyser objects now have :lower() and :raise() functions, so you don't have to call them via the lowerWindow(name) and raiseWindow(name) anymore. Geyser is all about adding methods to make it easier to build and maintain a nice graphical interface to your games, so little improvements like this matter!

Thanks to dicene for adding this in.

Shout out to Jor'Mox

Congratulations to Jor'Mox for writing over 1000 posts in Mudlet's forums. Thank you for your ongoing support, especially in helping new players with mapping their games with ease, by adapting the generic mapper script to whichever circumstances they may find, and so much more!
