Changing URL path in CSS - 111 entries

What's the quickest way to swap out all the URLs in a CSS file? Is it wasted keystrokes using look-behinds and look-aheads?

I just intended this to be a simple search and replace that might possibly generate some macros or normals solutions that are quicker)

I have some raw data from terminal output which uses carriege return for formatting.

I'm kind of unsure if I should have skipped lines 9 and 15, since there might be some interesting solutions which are not that generic. Happy Golfing!

Convert regular pandoc footnotes to in-line notes - 51 entries

Pandoc extends markdown by allowing footnotes, which are usually represented with a footnote identifier followed later in the document by the footnote itself. But Pandoc also allows inline footnotes without identifiers. How many strokes does it take to convert regular footnotes to inline notes?

I finally tested this locally using the Vimgolf vimrc and did a "gq" on the entire buffer as the last step. Apologies if I'm making a newbie mistake. First time submitter.)

LaTeX to XML Math Delimiters - 35 entries

Vim is amazing when used to edit MediaWiki text, but typing "<math> . . . </math>" can be tiresome and frustrating if formulas are used often. LaTeX delimiters are so concise and even come in two flavors: "\( . . . \)" for inline math and "\[ . . . \]" for centered formulas. The goal is to perform the following conversions: "\( . . . \)" becomes "<math>. . .</math>" "\[ . . . \]" becomes "<center><math>. . .</math></center>"

Change The Perspective - 27 entries

This is a go game recodes file(.sgf file, refer to http://www.red-bean.com/sgf/). It base on such a coordinate system: in vertical direction, is from top(farthest end) to bottom, mark as a,b,c,...,s(19*19 board); in horizontal direction, is from left to right, uses the same notations. For Example, the coordinate notation 'cq', is the position at the bottom-left corner(vertical coordinate first). The record is from one player's perspective. We need to change to another's, but we don't want to change coordinate system, let it keep top to bottom and left to right. so we have to change the coordinates, a <-> s, b <-> r,c <-> q, etc. the Position 'cq', as transformation, it will be 'qd'.
