Interactive debugger and REPL for Imba.

npm:

npm i -g imba-shell

yarn:

yarn global add imba-shell

To start using imba-shell, run the following command:

imba-shell

To enable TypeScript, you can pass the --ts flag:

imba-shell --ts

Note, you can also use imbas instead of imba-shell.

To use multi-line mode, use the .editor command:

>>> .editor

This will open a multi-line editor.

When using multi-line mode, you can use the Shift+Tab key combination to indent the current line.

To remove a tab, use the Backspace key.

To clear the imba-shell, use the clear helper:

>>> clear!

You can also use the .clear command.

To exit out of imba-shell, use the exit helper:

>>> exit!

You can also use the .exit command.

You may use imba-shell as a runtime:

imbar file.imba

imbar aliases: imba-r, imba-runtime, ir .

Passing arguments to your script:

imbar craftsman.imba mail:send --help

Continously build and watch project (development purposes):

imbar --watch server.imba

flag: --watch

alias: -w

Creating a self executing script:

#!/usr/bin/env imbar

const name = process.argv.slice(2)[0] ?? 'stranger'

console.log "Hello {name}"

If you're using Linux, FreeBSD or MacOS, you can make your script executable:

chmod u+x hello

Note: when creating a script that doesn't end with ".imba", the Imba Runtime will clone your script into a hidden file that ends with .imba and execute it instead of your original script. When done executing, the hidden file will be removed.

Running the script:

./hello Donald    # Hello Donald
./hello           # Hello stranger

imba-shell can also be used as a module. Here's an example:

Imba:

import { ImbaRepl } from 'imba-shell'

# you can also pass "typescript" instead of "imba"
const repl = new ImbaRepl 'imba', 'imba> '

repl.run!

JavaScript:

const { ImbaRepl } = require('imba-shell');

/** you can also pass "typescript" instead of "imba" */
const repl = new ImbaRepl('imba', 'imba> ');

repl.run();

Note, you can pass an object of Node.js repl options in the run function.

Here's an example of how to enable the history feature:

Imba:

import { ImbaRepl } from 'imba-shell'
import os from 'os'
import path from 'path'

const repl = new ImbaRepl 'imba', 'imba> ', path.join(os.homedir!, '.my_repl_history')

repl.run!

JavaScript:

const { ImbaRepl } = require('imba-shell');
const os = require('os');
const path = require('path');

const repl = new ImbaRepl('imba', 'imba> ', path.join(os.homedir(), '.my_repl_history'));

repl.run();

You can set any valid path as your history file.

You can register commands with the registerCommand function:

Imba:

repl.registerCommand 'goodbye', do
	console.log 'Goodbye!'
	this.close!

JavaScript:

repl.registerCommand('goodbye', () => {
	console.log('Goodbye!');
	this.close();
});

You may register functions and properties to be available in the REPL using the registerCallback function:

Imba:

const repl = new ImbaRepl

repl.registerCallback do(ctx)
	ctx.foo = 'bar'

JavaScript:

const repl = new ImbaRepl();

repl.registerCallback((ctx) => {
	ctx.foo = 'bar'
})

When calling foo in the REPL, it will return bar.
