--use-on-cd should revert to default node

[uloco]

The flag --use-on-cd should revert to default node if there is no .nvmrc present.
Is this already the case? Because it's just staying on the last used node version when switching in directories without one.

The way I would want it is. If you navigate into a child folder (without a .nvmrc) of a parent folder with a .nvmrc file then the version of node specified in the parent folder will still be used.

However when navigating to the parent folder of the folder with a .nvmrc it should load the default if there is one or system if there is no default.

This is how nodenv behaves
I've managed to implement zsh hook based on what is already provided by --use-on-cd. But it uses subshell so most likely not optimal. Native support of such behaviour from fnm use will be more efficient

autoload -U add-zsh-hook
_fnm_autoload_hook () {
    _node_config_path="$PWD"
    while [[ "$_node_config_path" != "" && ! -f "$_node_config_path/.nvmrc" && ! -f "$_node_config_path/.node-version" ]]; do
        _node_config_path=${_node_config_path%/*}
    done

    _node_current_alias="$(fnm current)"
    if [[ "$_node_config_path" != "" ]]; then
        _fnm_use_output="$(builtin cd -q "$_node_config_path" && exec fnm use 2>&1)"
    else
        _fnm_use_output="$(fnm use default 2>&1)"
    fi
    _node_updated_alias="$(fnm current)"
    if [[ "$_node_current_alias" != "$_node_updated_alias" ]]; then
        echo "$_fnm_use_output"
    fi
}

add-zsh-hook chpwd _fnm_autoload_hook \
    && _fnm_autoload_hook

Sorry that I had no response. #607 is what I had in mind for this. Now that I think about it, I can add the default version if it finds nothing.

Was this feature ever implemented?

Even though this issue is closed, the node version is not being changed if I cd to a directory that does not have an .nvmrc file.

Test in PowerShell:

Test in bash (just to make sure it is not due to #513):

Workaround

Create an .nvmrc file in the root directory of your drive with the version alias default as its content (rather than a specific version). This will cause fnm to recursively check each directory for an .nvmrc file until it reaches the root and then switches to the default node version.

Was this feature ever implemented?

Yes, but it requires an extra argument: --version-file-strategy=recursive. The README for this project probably needs updating to recommend this:

eval "$(fnm env --use-on-cd --version-file-strategy=recursive)"
