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 a to 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 @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.

If you’re at all familiar with the Linux/Unix world, it’s safe to say you’ve probably heard of vim. The mode-based editor is famed for both its power and frustrating learning curve. Unlike most editors, which default to a mode where you can type text,…
Looking to set up a blog with Ghost? While it still has a few rough edges and missing features at the time of this writing, as it’s essentially in beta at this point (hence the “0.3” versioning), it definitely shows promise as a blogging…
Need to throw together a quick dashboard with live-updated information and statistical readouts? Dashing is a fun new framework built atop Sinatra that lets you quickly setup dashboards, much in the style of Microsoft’s “Metro” UI. You can leverage premade widgets (which include numerical…
If you have worked at all with Linux, you’re probably familiar with the concept of a package manager. Type a short command and instantly install software. Programming languages even have their own these days, for managing libraries. Ruby has RubyGems, Node has NPM, PHP…
I recently migrated one of my blogs from WordPress to Jekyll and painstakingly ported my custom theme to the new blog engine. I didn’t notice it at first, but Jekyll makes a major typographic faux pas by default: it uses ugly, straight “typewriter quotes”…
