Error in nushell + tmux - hoping someone can help

[balanced-edmundsecho]

When I fire up a new window or pane in tmux, I get the following error:

Error: nu::shell::cant_convert

  × Can't convert to boolean.
    ╭─[Host Environment Variables:83:19]
 82 │ "__CF_USER_TEXT_ENCODING"="0x1F5:0x0:0x0"
 83 │ "__zoxide_hooked"="true"
    ·                   ───┬──
    ·                      ╰── can't convert string to boolean
 84 │ "is_vim"="echo \"#{pane_current_command}\" | grep -iqE \"(^|\\/)g?(view|n?vim?)(diff)?$\""
    ╰────

The auto-generated `~/.zoxide.nu includes the following snippet where we can see that we are indeed setting __zoxide_hooked to a boolean value (not a string).

# =============================================================================
#
# Hook configuration for zoxide.
#

# Initialize hook to add new entries to the database.
if (not ($env | default false __zoxide_hooked | get __zoxide_hooked)) {
  $env.__zoxide_hooked = true
  $env.config = ($env | default {} config).config
  $env.config = ($env.config | default {} hooks)
  $env.config = ($env.config | update hooks ($env.config.hooks | default {} env_change))
  $env.config = ($env.config | update hooks.env_change ($env.config.hooks.env_change | default [] PWD))
  $env.config = ($env.config | update hooks.env_change.PWD ($env.config.hooks.env_change.PWD | append {|_, dir|
    zoxide add -- $dir
  }))
}

Has anyone navigated this issue when using tmux with nushell? It's an error that fires-up when I start the a new window or pane, but does not actually prevent z from operating as expected. That said, when i start tmux from a stored session... I just can't. The shells fail to start-up as needed.

The following patch partially fixes the problem. It removes any errors when I create a new tmux pane or window. That good. But my ability to restore a session is hit and miss. Some of the pains are not institutionalizing correctly.

In general, tmux seems to pass $env value as strings. The script needs to support deserializing accordingly.

Update zoxide to v0.10.0 and regenerate your init file:

zoxide init nushell | save -f ~/.zoxide.nu

The old init script stored __zoxide_hooked as $env.__zoxide_hooked = true. Tmux serializes all env vars as strings when it spawns a pane, so nushell sees "true" instead of true and throws cant_convert. The v0.10.0 template doesn't use that env var anymore. It checks the hooks config with a local variable instead, so tmux can't break it.

You'll need nushell v0.106.0+ for the new init script.
