Don’t you just hate it when you have to do some repetitive text editing, such as wrapping several lines of text in <li>...</li>
tags or just about anything involving tables? (Actually, HTML is a veritable goldmine of repetition…) If you use vim, you can whip up macros on-the-fly to reduce this sort of tedium.
The commands to know are:
q
— Start or stop macro recording. When starting, it should be used with a letter froma
toz
, which is the register it will record into. (So you can have more than one macro in memory at once.) The command is used singularly to end recording.@
— Play back the macro. Use it in the form of@a
to play the macro in register a.@@
— Play the last-played macro again.
Rather than explain it in textual form, I recorded a short screencast that illustrates the basics of using macros in vim.
