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 from
z, 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
@ato 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.
