Vim copy and concatenate the lines

I got a file that looks like this:

G:\some_folder
    file1.avi
    file2.wav
E:\some_folder2
    fileABC.avi
    fileDEF.wav

I would like to transfer the file into:

G:\some_folder
G:\some_folder  file1.avi
G:\some_folder  file2.wav
E:\some_folder2
E:\some_folder2 fileABC.avi
E:\some_folder2 fileDEF.wav

So in other words this might work like this: look for ^[A-Z]: copy whole line and add it at the beginning to next lines till you find ^[A-Z]:

is it possible to do that in VIM? If yes, how.

thank you Radek

Solution

  • I would iterate over all lines with :global; Vim will position the cursor on the beginning of each line. Depending on which kind of line it is, I'd either yank the folder path, or paste it in front:

    :%g/^/execute 'normal!' getline('.') =~ '^\S' ? 'y$' : 'P'
