True, I didn't think of that version.

How does one sort words with a line ? As example I have these numbers in a
line:
400, 250, 125, 600
I want to sort them so they will be 125, 250, 400, 600
I have tried the visual command then !sort but that doesnt do it.

you can take advantage of the second, optional argument to split() and
save the call to substitute():
:call setline(line('.'),join(sort(split(getline('.'), ',\s*')), ', '))
This splits the line on every comma optionally followed by white-space.
If there is a trailing comma, split() automatically removes it. Like in
your second version the comma has to be added back later.

There is still room for improvement. For example if you consider this
line:
400, 250, 125, 600, 100
this would be sorted to:
100 125, 250, 400, 600,
(which looks not right if you look at the commas).
So here is a slightly changed version:
:call setline('.',join(sort(split(substitute(getline('.'), ',', '', 'g'))), ',
'))
(one line)
Basically, this replaces the comma and adds it later back.

Christian

Amazing amazing that works also. Seems there is always more than one way to
skin a cat.

:call setline(line('.'),join(sort(split(getline('.'))), ' '))

As example I have these numbers in a line: 400, 250, 125, 600 I want to sort them so they will be 125, 250, 400, 600 I have tried the visual command then !sort but that doesnt do it. Generally one uses a "decorate-sort-undecorate" pattern to do this sort of thing. There are a couple edge-cases that you'll want to take note of: 1) all your example numbers are 3 digits. Do you want them to sort numerically or lexicographically (should "111" come before "12"?) 2) you have commas between them and happen to end with the largest. Do you expect "5, 4, 3, 2, 1" to sort to "1, 2, 3, 4, 5" or "1 2, 3, 4, 5,"? The DSU pattern would look something like :y " yank the current line :new " create a junk buffer :0put " dump the line :$d" delete the extra blank line :s/,\s*/\r/g " put each on its own line :sort " sort them lex. or :sort n" sort them numerically :1,$-s/$, " put the commas back in :%j" rejoin into one line :d " cut the line :q!" quit the scratch buffer :put " put it below the target line :-d" delete the previous unsorted line which could all be rolled up into a mapping or function. Note that it does tromp your scratch register, but a little care can prevent that by saving & restoring it. -tim -- You received this message from the "vim_use" maillist. Do not top-post!
