Smart word wrapping in `less`?

Question

I use the Python package rtv as a terminal client to read Reddit. When it gets to a large text box, it calls less display the text. Currently, less wraps the words according to column width, meaning that sometimes you get cut off in the middle of the word. Is there a configuration or tweak that can make it only fold where there is whitespace?

Answer 1

Put this in your .bashrc or similar configuration file.

export PAGER="/bin/sh -c \"fmt -s -w $(tput cols) - | less\""

Answer 2

One solution is to use the -S (--chop-long-lines) command line option for less. This tells less to truncate lines to the width of the screen. To view the truncated lines that are wider than the terminal, the left and right arrow keys can be used to scroll the window horizontally.

You can enable this behavior by adding -S to the command line or setting the environment variable, LESS, like this in Bash:

$ export LESS='-S'

Answer 3

I use the unix toolbox for my terminal/bash viewer:

alias v='(fold -s -w75 | nl -bn -w10 | LESS= less -MINRz-4+G:1g)<'
