Look everywhere

It's a factor - 85 entries

Flaunt your macro prowess by factoring some numbers. Too hard? It takes less than 30 strokes, I promise.

Sort the VimGolf challenges by popularity - 330 entries

"Sort by popularity" is a good order to play the challenges. Not perfect, but you could do a lot worse. ;) Input is a sample copy-pasted from vimgolf.com. Some of the challenge names have digits that will get in your way, so read ":help :sort" for hints on sorting with a regex. When you're done, try your solution on the full list!

Extended Customer 2 - 44 entries

Format the chars

Parsing with CSV: Unify lines and result. - 163 entries

A relatively common Javascript refactoring.

vim = 22 / 7 - 415 entries

pi square vim

Chinese Multiplication Table - 70 entries

Print a Chinese multiplication table in Vim. In China, every kid is asked to memorize this table. And thanks to the mono-syllabism of Chinese characters, it is not that hard. Printing the multiplication table is also a good exercise for programming beginners. For-loop, escaped characters, etc... There should be some special ways to print it in Vim.

LaTeX to XML Math Delimiters - 40 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>"

Define to require - 118 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.

Minimalist Limerick - 500 entries

Reproduce this lovely poem.

Saving the hashes(#) - 1940 entries

The following file is copied from vimcasts.org(Its only for learning purpose,hope the site owner doesn't mind it), its probably the easiest of challenges.Our goal is to delete every line which doesn't contain a hash signs. The remaining hash signs with numbers are then sorted to get the final output.

Word frequency alignment - 233 entries

You've got to align the second column, but the spacing is inconvenient and there are nasty tabs in the way. If you're a "real Vim ninja," this could be very quick indeed...

Circle in a square - 125 entries

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

Greek Letters - 59 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!

Transposition - 67 entries

Transpose the original lines in separate columns, one for each line.

REDRUM - 139 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.

Enumerate words - 226 entries

Enumerate the unique words in order.

Swap assigned value - 540 entries

Simple problem but looking for interesting solutions.

abcd > a b c d - 252 entries

transform the single spaces into 4 spaces repeat for each line

lamb had a little Mary - 538 entries

"Mary" and "lamb" are swapped. Unswap them. Fast as you can.

Python: Lots of function arguments - 73 entries

The function definition is too long for one line. The modeline helps you with some typical Python indent settings.

Checkerboard case pattern - 127 entries

All the squares are white. Make some of them black. But only the right ones.

Readable Rubyhash - 233 entries

Rubyists talk about being cutting edge but how many are using 1.9 in production? Time to convert those verbose 1.8 hashes in to symbolic, succinct 1.9 beauties!

Chucking wood - 80 entries

An exercise in compressing repetitive text. For this challenge, any entry that uses keys outside the main row (such as arrow keys, Home, End, Delete, etc.) will be removed. (Esc is OK, though you should be using C-[ anyway.)

Flip the chessboard - 67 entries

White's turn is over. Flip the board to black's perspective. I added coordinates to frustrate you.

Same numbers as last time, but you'll have to add them yourself.

Sort by sum of numbers in a line(?) - 45 entries

The lines with the biggest sums need to be at the top. The sums are on the right, which makes life hard. Maybe you can find a feature that will do all the work for you...
