Nearly three years ago I announced a significant overhaul of Tk on the Mac that amounted to a redesign of major portions of the GUI library. The changes were intended to address flaws that had emerged in the initial, whole-cloth migration of Tk from the Carbon to the Cocoa API by Daniel Steffen. At the time I envisioned that this overhaul would put Tk on sound, stable footing going forward, and would require only routine maintenance and the occasional feature enhancement.
Ah, the best-laid plans of developers. Tk on the Mac in fact was NOT in a complete place, and later that summer, Marc Culler, who contributed many of the critical patches for Tk-Cocoa 2.0, and I did some additional major refinements. At that point Marc's contributions were so substantial that he essentially became the co-maintainer of Tk on the Mac, and I added his name to the author list.
Over the past six months, we have gone through an additional heavy round of development on Tk, to the point where I consider this yet another major iteration of the toolkit and not just an incremental set of updates. Should this round be called, informally at least, Tk-Cocoa 2.5? I think so.
This round of development was led by Christian Gollwitzer, who implemented some long-broken functionality in file dialogs; Marc Culler, who fixed some major crashing bugs on macOS 10.13 and implemented several major, low-level improvements to drawing and image code; and Francois Vogel, who worked closely with Marc on the drawing code specifically with the text widget and who has undertaken an ongoing cleanup of the Tk test suite on macOS.
Here's a quick overview:
While I did most of the early heavy lifting on updating Tk-Cocoa and was later joined by Marc, in this round I contributed far less code. Marc has done most of the substantial work, with Christian making a major contribution with the file dialogs, and Francois has provided ongoing consulting on integrating these changes into other aspects of Tk. It's great to have more developers working on Tk on the Mac these days; it has allowed us to make infinitely faster progress on fixing bugs. It also adds far more expertise to specific problems; Marc and Francois have expertise in certain areas that I've never been able to master, and Christian's work would have taken me some time to equal. I'm grateful for their efforts.
Right now this work can be downloaded from the core-8-6-branch of Tk at its core development site, and it will soon make its way into the next stable point release. Keep an eye out for it, and give it a try.
