I am using nvim to edit tex files. I don't know what happened. All of a sudden, tens of blank lines emerged before each line of codes. I think maybe I screwed it up by doing something wrong unconsciously. Does anyone can shed light on some ways to fix it? thanks!
My suspicion is that you have done some "repeat" command by typing a number in normal mode before applying a command, probably block-wise.
Consider this:
If you block-select the first column, and then insert a space (or indent) 100 times, command Ctrl-V G 100 I <space> <esc>, you have:
it seems you have inserted line, but it is just space.... use `:set nowrap" to remove the soft wrapping of lines, and enlarge the window:
Now you could use a regex, but you can also use normal blockwise: Ctrl-V, select the blank space:
and then d will remove it.
'wrap'turned on, and that there's really a large number of whitespace characters (not blank lines) at the beginning of the line. You could try==or<<.....to unindent if the indentation settings are still correct. – D. Ben Knoble Sep 21 '20 at 12:48
