PHP Array Syntax -> MailChimp Merge Syntax - 427 entries

I recently needed to send an e-mail to our marketing department listing allowed merge tags for our MailChimp campaigns. The allowed merge tags were determined from a PHP array in one of our PHP classes. I transformed the PHP class to MailChimp's syntax and sent the e-mail. It was, however, a long, laborious process. I'm still fairly new to Vim and would love to see how an expert Vim user would tackle one of my own, real-world problems. Thanks and have fun!

Unsemantic linewrapping - 470 entries

[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:

comment and uncomment code inline - 862 entries

It's very useful to be able to comment out a block of code in a quick edit. And likewise to uncomment the code. This operation often involves multi-line stanzas and even large blocks. With just line-wise navigation and insert mode this would cost you about 4 keystrokes per line. Master this hole of VimGolf and you'll quickly drop your key count in day to day Vim as well.
