formatted text to markdown - 173 entries

You're converting some posts from an old blog to markdown. The formatted text is far closer to the finished product than the html markup, so it seems like a good place to start. Word wrapping seems to be the main area for optimization.

Assign numbers to fields - 82 entries

You are given a list of space-separated strings. Add an increasing numeric prefix to each one.

Complete the hex array data - 174 entries

Do not use external tools(e.g. tac, seq) [My interpretation of Rule #7]

Multiplication table. - 171 entries

Create a multiplication table.

Create a pandoc compatible table - 148 entries

In [this vimcast][1], a featured gist from Tim Pope shows how to quickly make a simple table structure. How fast can you convert it to pandoc's markdown style? [1]: http://vimcasts.org/episodes/aligning-text-with-tabular-vim/

Inconsistent real estate paste - 142 entries

Format a hand-typed real estate listing that uses inconsistent punctuation into four sections

REDRUM - 131 entries

If you remember "The Shinning", the first time you saw the bloody word REDRUM you probably thinked "What the Hell is that?" Well, then you know that you need a little help from a looking-glass to make sense of it. Now it's time to use vim like a mirror to reveal the message.

Almost encrypted - 165 entries

Convert the first paragraph to be even less readable.

Circle in a square - 125 entries

Probably looks more like "Egg in a rectangle" in most fonts, but it's actually 23x23.

Winding path - 91 entries

It's a maze, but the bad paths have been blocked off. Mark the correct path.

Convert pandoc unordered list to a numbered list - 131 entries

I know it's possible to use #. in pandoc to auto-generate numbered lists, but then it's not easy to tell how many items there are when reading it in Markdown. How fast can you make the switch?

Solve the Sokoban - 158 entries

A wink for all Vimgolfers that play Nethack too.

SFD-ROC: Tic-Tac-Toe - 124 entries

Entries sort - 71 entries

It cames to my mind a weird idea : sorting parts of my .vimrc. Take few minutes to sort out this, it's easy !

Define to require - 113 entries

When JSHint is enabled, there's a rule that doesn't let you have more than 6 arguments in a function, so the moment you need to add a 7th argument, you need to do a refactoring.

Real-life challenge, convert a bunch of ifs to a switch statement

CSV to JSON - 143 entries

A search for shortest vimissh way to convert CSV to JSON.

Getters & Setters: Java - 141 entries

Boilerplate getters & setters - it's a tedious fact of life in Java, and probably the only thing that still pulls me back to an IDE. Perhaps someone knows a fast, pure vim way...

Long prime list - filter version - 19 entries

I've used the maximum input/diff/output size allowed by vimgolf to get a list of integers up to 1460 separated by newlines, and your goal is to only keep the lines containing primes. There are 232 of them I hope some of you will golf vimscript itself to create some function to run as a primality check for each line, which is a good exercise if you haven't done much vimscript yet! You're invited to also try copy-pasting and doing other non-smart text manipulation. Even more interesting would be to see a solution that uses text manipulation to do the filtering! Whether you use vimscript, normal-mode primality checks, or text manipulation, as long as the end result is valid, your answer will be valid! Let's see which method does better here. Best of luck!

Fill visual area - 70 entries

Just have fun!

Checkerboard case pattern - 106 entries

Turn a ninja to case-insensitive [Nn][Ii][Nn][Jj][Aa] regexp! - 40 entries

I bumped into this in a dailywtf code: http://pastebin.com/QApa5ycS I didn't want to translate a string whenever I wanted to be [Ss][Aa][Rr][Cc][Aa][Ss][Tt][Ii][Cc] on slack, so I figured a script (python, sed, whatever) would be helpful. Well, or a few vim keystroke!

Write Setters and Getters for PHP - 86 entries

Just simple automation of writing Setters and Getters like Doctrine might use.

Sort yaml structures alphabetically by root key names - 25 entries

sometimes we want to sort structures alphabetically in yaml files

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'm sorry for the delete/report--I made a mistake with the last one requiring an ugly search for graphic to replace with images. I just intended this to be a simple search and replace that might possibly generate some macros or normals solutions that are quicker)

Overall Vimgolf Rank - 132 entries

Suppose you are trying to figure out what your overall rank is at Vimgolf(the sum of all the ranks you got), and as a Vim ninja you decided to use Vim to do the job. Your solution should work for every Vimgolf profile page(The actual input file for this challenge is my Vimgolf profile page). So, direct answer insertion is considered cheating.
