Vim continues to surprise me with its wonders. Sometimes (many times, in fact) things do not make sense, and I am perplexed as to the reasoning behind them. Then, one day, I grokked it. And from that day on, I can never imagine any other way of doing it. An example of this was my confusion over the apparent redundancy of two fundamental commands. In normal mode Vim, “s“ (mnemonic: “substitute”) and “c” (mnemonic: “change”) are both ways to remove some existing text and then go into insert mode.
It is past 4 am, and the bug hunt is over. It was a weird one. One that I’ll remember. It led me on a wild exhausting chase through dark nooks and crannies of a horribly-written nightmare of a code base. What made it weird was that, with the same random number seed, I got different behavior depending on whether there were some (debugging-related) print statements in some parts of code.

I love text editors. Which is a good thing, because I spend the overwhelming majority of my computing time (and, hence, sadly, most of my conscious life) in one text editor or another. For years I have been an Emacs user, only relatively recently moving to BBEdit with my adoption/inheritance of a Mac as a personal machine. Using and often administrating Linux-based systems has necessitated that I use Vi now and then, but I have long held the opinion that the only Vi command one needs to know is: “:q!
