| 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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)) |

Recording (a macro) in vi
There are time that I'm editing a file with vi, and I note that my editor says "recording on the bottom of the screen / status bar. What have I done? Is this useful? Can / should I turn it off? • If you type "q" followed by another keystroke in command mode, you start recording into a macro buffer who's name is the same as the second keystroke - so "qa" means start recording macro a. • When you next type "q", the macro recording will cease. • When you then type "@" followed by the macro letter, you'll rerun the key strokes that you recorder in the macro. Example ... move over the middle of a line of text in vi then qa (record) dlph (swap the current character with the next one along) q (end recording) then @a (to swap the charactets back) and you can use @a anywhere else to swap characters in your edit session. I've concluded that the reason I find myself recording sometimes when I hadn't intended to is because I key too quickly - q is very like :q, and the q key is right beside the tab key. But at least I now know what the worrysome message means, how to get out of the recording mode - and I've learned about a useful new procedure into the process!
