/usr/bin/env: ‘node’: No such file or directory

vhbui02

At the start of a Fish Shell, by default it doesn't source nvm to preserve speed.

=> By default, $PATH don't have /bin directory /home/darkswordman/.nvm/versions/node/v18.16.0/bin

Common error

Since there are programs, plugins (e.g. plugins in SublimeLinter), sometimes they need to know where node is to run some node command.

Since we only source NVM when we use one of the aliases (function aliases, NOT binary aliases), and these function aliases only exists in Fish Shell.

Adding action listener

Nested class implements ActionListener and overrides actionPerformed.

public class Foo{
    Foo(){
        something.addActionListener(new ButtonListener());
    }
 //...

Slow performance after some time?

Check your Model Explorer, there's a high chance that your root is filled with model elements from various diagram and package. By default VP will load all of root's child, except Models which are loaded when used.

=> Solution: Try to put all of them into 1 Model (this Model is added to the root)

function NAME [OPTIONS]; BODY; end

-a or --argument-names NAMES: assign the names for each argument passed into function, there are the same arguments given in $argv

Where are universal variables stored in Fish shell?

Inside ~/.config/fish/fish_variables

*Do not edit this file directly, as your edits may be overwritten.

=> Instead, edit the variables through fish scripts or by using fish interactively.

*Do not append to universal variables in config.fish, because these variables will then get longer with each new shell instance.

funced

funced [OPTION] [NAME]

funced provides an interface (an external editor like VSCode, Vim, Notepad, ... or a built-in editor) to edit the definition of the function NAME

If the $VISUAL env var is set => it will be used

If not, but $EDITOR is set => that will be used instead
