less command and syntax highlighting
U1and0 2017/03/29
â€œless doesn't support syntax highlighting. vim, like all vi clones has a read-only mode called view which you can use to just view files. it supports all features of vim including syntax highlighting.â€ But `source-highlight` package exist? pacman can't install.
