If imitation is the sincerest form of flattery, then the latest release of adv3lite, version 1.3, which is now available for download, is at least moderately flattering both to the original adv3 library and to Inform 7. Inspired by the former it adds two new extensions to the adv3Lite library, Footnotes (which allows footnotes in precisely the same way as the adv3 library does) and subtime (based on Mike Roberts' Subjective Time extension, which allows the author of a work of IF to link key events to particular times and then extrapolates between these times whenever the player character consults a timepiece). Inform 7 implements a more objective notion of time, the time of day which is advanced by one minute every turn. The latest version of adv3Lite now has an extension (Objective Time or objtime) to do the same thing (along with related functionality such as a special type of Fuse that is triggered by the game clock reaching a certain time). The objtime extension also incorporates all the functionality of my I7 Variable Time Control extension (allowing game authors to control exactly how much time each turn takes down to the nearest second, assuming anyone had the patience to implement quite so much detail).
Further flattery - or at least imitation - of Inform 7 is planned for the next release of adv3Lite (whenever that will be), for which I'm in the process of developing extensions for I7-style rules and I7-style extensions. In the meantime a complete list of what's new in the latest Version 1.3 release can be found by consulting the change log.
