For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |
Expect for Windows
I've just noticed on the Activestate site that "the ActiveTcl distribution now includes Expect for Windows. A license is no longer required ....". At face value, that looks like excellent news!
One of the big uses of Tcl and Tcl/Tk is in the automation of processes / programs that are designed to work from the command line and don't have an easy interface for other automata to use them. For example, if you run a regular ssh or telnet session every day, you can automate it with relative ease through Expect, where you choreograph the session in a series of "I say this" and "you say that" type statements.
Expect was written originally for Unix and works well on Linux and OS X. Up until a year or two back, only older and somewhat unsupported / unstable releases were available on Windows due, I understand, to the underlying operating system making it quite an issue to implement the multiprocess environment expect requires. Then Activestate brought out a commercial, license-only expect extenstion to ActiveTcl. This has always felt a bit - unfortunate - that a piece of software that started as Open Source became commercial-only in this guise and I'll be off to look at the licensing agreement when I get the odd spare moment to see if it's now - as I hope - free at the point of distribution and on a license under which that distribution can be used in perpituity. With a confirmation of the latter, you'll find me grinning from ear to ear!
Added, 10th September ... I AM grinning from ear to ear. I had a chance to download and test Expect for Windows and it ran nicely, without any problems. See full source code of my example
