File tree workaround for Helix

nnn as a file tree workaround for Helix

Many people have expressed that the absence of a file tree is what prevents them from using Helix.

If, for some reasons, you cannot use the PR #5768, here’s a workaround to create a file tree using WezTerm and nnn

The idea here is to implement a custom opener in nnn. When navigating to a file, it will be opened using hx in the right pane. When opening another file, it checks if there is a running instance of hx in the right pane and sends the :open $1\r command to that pane.

Here’s the implementation:

#!/usr/bin/env sh
            
          fpath="$1"
          
          pane_id=$(wezterm cli get-pane-direction
            right)
          if [ -z "${pane_id}" ]; then
           pane_id=$(wezterm cli split-pane --right
            --percent 80)
          fi
          
          program=$(wezterm cli list | awk -v pane_id="$pane_id" '$3==pane_id { print $6 }')
          if [ "$program" = "hx" ]; then
           echo ":open ${fpath}\r" | wezterm cli send-text --pane-id
            $pane_id --no-paste
          else
           echo "hx ${fpath}" | wezterm cli send-text --pane-id $pane_id
            --no-paste
          fi
          
          wezterm cli activate-pane-direction --pane-id $pane_id right
          
$ export NNN_OPENER=nnn-hx.sh
          $ nnn -c

This allows you to efficiently manage your files and work with Helix using WezTerm and nnn.
