What languages have extant parser authoring tools in the modern era? Yes, many languages had parser games in their heyday, but this doesn’t tell us how many have authoring tools for them currently.
I’m aware of DAAD and ports of Inform and TADS to various European languages, but not anything beyond that.
French has Donjon which is basically its version of Inform, being rule-based and mimicking natural language.
Example code from its documentation
La place du village est un lieu.
La torche est un objet dans l'inventaire.
La fontaine est un contenant ici.
Sa description est "Une fontaine gélée.".
La glace est un objet décoratif et indénombrable dans la fontaine.
L'éclat est un objet fixé dans la fontaine.
Sa description est "Vous distinguez ce qui semble être un objet prisonnier de la glace.".
Son aperçu est "Sous la glace[@glace], vous voyez un éclat brillant.[@éclat]".
-- n'étant pas positionnée, elle n'apparaît pas dans le jeu au début de la partie.
La pièce dorée est un objet.
règle après utiliser torche sur glace ou utiliser torche sur éclat:
dire "Vous parvenez à libérer un médaillon doré.".
effacer l'éclat.
déplacer la pièce dorée dans la fontaine.
fin règle
The last post in that thread was less than 2 weeks ago, so I don’t know if I’d consider that necromancing a topic from the grave. Besides, while I know necroing stuff is a big taboo in many forums, frankly that isn’t much of a cultural taboo here.
That said, the topic is distinct and you’re free to do whatever you wish even if it weren’t. I just didn’t want folks to get the impression that they’d get digitally stoned if they necroed a thread on this forum.
There are several more in development, though (it’s a fact that, at any given point in time, there will be more people in the Spanish IF community writing development tools than games).
I checked out the WACS preview and while the IDE is incredibly slick, the language sticks to the 8bit guns: assembler-like instructions and number-indexed tables for locations, objects and messages. It’s like (syntactic) sugar-free Adventuron.
