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? (NB: I've had trouble figuring out whether text-width makes a difference to Vimgolf in comparing the input and output file. 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.)

Change The Perspective - 20 entries

This is a go game recodes file(.sgf file, refer to 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'.

LaTeX to XML Math Delimiters - 24 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>"

Refactor to Helpers - 41 entries

This Rails partial is almost all template escapes. Put it into a helper, and refactor each case to methods so we can build out the controls for each. (I've converted to tabs - fighting with Vimgolf's default config shouldn't be part of the challenge.)

Greek Letters - 24 entries

Starting with a list of Greek letters, create a cross-reference table showing all of the Greek alpha-beta. You'll likely need to use digraphs (:help digraphs). Note that while most digraphs can be entered with either character first, lowercase sigma has two digraphs -- s* AND *s! Good luck!
