| - I needed to sort a file according to the number of words in each line. Using the :s command, I inserted the number of words each line contains, at the beginning of the line. To simplify sorting (using the excellent VisSort), instead of inserting a number, I put the corresponding character (number plus 64, so a line with one word will start with 'A'). Here is the expression I used: :%s/^.*/\=nr2char(strlen((substitute(substitute(submatch(0), "\\S\\+", "x", "g"), "\\s","","g")))+64) . " " . submatch(0) Explanation, from the inside out: part1 = substitute(submatch(0), "\\S\\+", "x", "g")

| - I needed to sort a file according to the number of words in each line. Using the :s command, I inserted the number of words each line contains, at the beginning of the line. To simplify sorting (using the excellent VisSort), instead of inserting a number, I put the corresponding character (number plus 64, so a line with one word will start with 'A'). Here is the expression I used: :%s/^.*/\=nr2char(strlen((substitute(substitute(submatch(0), "\\S\\+", "x", "g"), "\\s","","g")))+64) . " " . submatch(0) Explanation, from the inside out: Replace all consecutive non space by a single x (each word is now a single x): part1 = substitute(submatch(0), "\\S\\+", "x", "g") Remove the spaces between "x": part2 = substitute(part1,"\\s","","g") Count the number of "x": part3 = strlen(part2) Get the ASCII char representing the number of words + 64: part4 = nr2char(part3+64) I replace all lines (^.*) by that ASCII char, followed by a tab and the initial line itself. I can then sort, then remove all characters between the beginning of lines and the first tab.
