vim reverse lines
:g/^/m0vim reverse lines
:g/^/m0vim reverse range of lines
To reverse lines a to b in vim, use this template:
:a,bg/^/ma_minus_1
Explanation:
- : enters command lines mode
- a,b gives the range of lines to reverse; omit reverse all lines
- g says "apply command to all lines matching this regex"
- /^/ is a regex matching the start of a line, which all lines have
- m is the Ex command for "move"
- a_minus_1 is the move destination, which needs to be one less than the start
of the range to reverse the lines, so a_minus_1 = a - 1
Examples:
- Reverse lines 10-20:
:10,20g/^/m9
a = 10, b = 20, a_minus_1 = 9
- Reverse all lines in the buffer:
:g/^/m0
a = 1, b = (last line), a_minus_1 = 0Copyright © 2021 Codeinu
