Multiple commands to trigger lazy loading (znap function)

[michaeldebetaz]

Hi everyone 👋

I am very happy with znap and, as many, I use it with the nvm plugin. As nvm takes forever to load, I leverage the very useful znap function nvm load_nvm() trick that saves me time when loading zsh.

But I sometimes need to trigger the lazy loading with other commands, like npm npx or nvim.

Here is what I do in my .zshrc file to ensure that it triggers for each command:

load_nvm() {
    export NVM_DIR="$HOME/.nvm"
    [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
    [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
}
znap function nvm load_nvm
znap function npm load_nvm
znap function node load_nvm
znap function npx load_nvm
znap function nvim load_nvm

Is this the correct way to do so or am I doing something wrong?

As mentioned in the Readme, znap function can create multiple lazy-loading functions at once. Just pass all the command names you want to lazy-load before passing the actual code to run. So, for your case:

load_nvm() {
    export NVM_DIR="$HOME/.nvm"
    [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
    [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
}
znap function nvm npm node npx nvim load_nvm

Znap will auto-remove all five of the functions this create when you first try to run any of these five commands.

Thank you for the clarification! I read the part of the Readme, but it wasn't clear for me that this was the implementation. Sorry for my lack of understanding 😋

Again, thank you so much for your work!
