How I make sure my burrow phlog posts are not too wide
January 25th, 2019
----------------------------------------

Here's a nifty one, sometimes when making phlog posts, I run into GNU
nano doing a very bad job word wrapping, which results in the phlog
looking bad in say lynx on a standard 80x25 terminal.  No biggie, I
setup a function to give me a hand.

Software used:

• GNU bash 4.4.23 in POSIX mode
• tmux-SIXEL ( https://github.com/saitoha/tmux-SIXEL )
• burrow ( https://github.com/jamestomasino/burrow )
• GNU nano 2.9.6

My function is placed into ~/.bashrc, here's what it does:

• Checks to see if it's being called from a running tmux (case $TERM)
• Saves tmux window title from before burrow running
• Renames current tmux window to "burrow"
• Sets current tomux window to 73 characters wide
• Traps ctrl+c to restore window title if interrupted
• Tells nano to try to wrap at 72 characters and runs burrow
• Renames window back to its original name when burrow is done
• Restores tmux to default window width
• Sets return code in case running from another script

Here's the condensed code I am using in ~/.bashrc:

case $TERM in
  tmux*)
    burrow() {
      local code=0
      local ancien
      ancien=$(tmux display-message -p '#W')
      tmux rename-window "burrow"
      tmux setw force-width 73
      trap "{tmux rename-window $ancien ; tmux setw force-width 0 }" INT
      env EDITOR="/usr/bin/nano -r72" burrow $@
      code=$?
      tmux rename-window $ancien
      tmux setw force-width 0
      return $code;
    }
  :;;
  *)
  :;;
esac
