Only two months left in this year. Which may mean the accumulation of deadlines or the coming of your season's festivities. As always, the Wiki is a reliable source of information on Tcl and Tk. '''Software updates''' The famous interface to Windows system functions has reached a new version - check out version 4.3.8 of [TWAPI]. One application of [TWAPI] allows you to automate all manner of well-known "office" programs, such as MS Excel but also Google Earth: one package to rule them all, under the inconspicous name [CAWT]. If you are dealing with JSON, then you be interested in the [JSON value extraction benchmark]. As there are a lot of libraries out there, choosing the one that is right for your applications is a tricky process. Do not expect an absolute answer. Some widgets simply do not fit on a single screen and require some form of scrolling. Try [Scrollutil] to make your life easy, when you run into that! Tcl exists in a variety of implementations. For the Windows platform, read ".NET", you might benefit from [Eagle], as that works seamlessly with said platform. To get some feeling for it, perhaps join the [Eagle sandbox Contest]? '''New (?) kids on the block''' Let's discuss climate change and other world-wide problems in a different context. The [OpenSky App] does not judge, it simply shows the flights of planes that you select. A beautiful cartoon-like picture appeared this month on the Wiki: a head of a tiger, illustrating the capabilities of the [Blend2d] library. Arduinos are those nifty little gadgets that can do all manner of remarkable things. At least, if you tell them how to do it. [Firmata] may help you use Tcl for this conversation. '''Widgets, snidgets and other graphics''' A listbox able to show multilne entries, check out the [tlistbox] package. Clocks need not be round with two hands, nor the digital gadgets of long ago. The [Tk Dali Clock] is a playful variation, no sudden change in the digits, but a smooth morphing. [Cloning a Gnocl Widget Made Simple]? By the looks of the code, it is indeed really simple. '''Dive into details''' [Abstract Data Types], who does not know them? This page discusses them at some length - for a rainy sunday afternoon, perhaps? The mysteries of character [encoding]s unravelled ... Perhaps save that one for a rainy evening. Probably every programmer has to do this at some point: examine the contents of a recursive structure, say, of directories. Such [Directory recursion] can be done in many different ways. For the puzzlers. The Wiki is not known as a source of information on the animal kingdom. So, not surprisingly, [duck typing] is only superficially about waterfowl. <<categories>>Category Tcler's Wiki
