Denosh

Denosh is a command line tool solution for Deno.

Installation

deno install --allow-read --allow-write -f -n denosh https://deno.land/x/denosh/denosh.ts

*Cation: If you choose to use this way, you can just use bulltin commands, and it’s not that useful

--allow-read and --allow-write, this is the default permission needed, if your commands use more permission, you can add here, or just use -A.
-f means override last install.
-n denosh is for naming the installed executable binary.

As a mod

import { launch, registerCommand } from 'https://deno.land/x/denosh/mod.ts'

import * as test1Command from './src/commands/test1.ts'
import * as **test2Command** from './src/commands/test2.ts'

registerCommand('test1', test1Command)
registerCommand('test2', test2Command)

if (import.meta.main) {
  launch(Deno.args, {
    scriptName: 'Your script name',
    commandDir: 'Command directory',
    exclude: ['generate'] // disable registered commands
  })
}

Add a command using generator

There is a built in command, called generate, it’s very easy to generate a simple command structure, it use the commandDir in launch option to know where to write the command.

deno run cli.ts test3

Command structure

export const name = 'test'
export const desc = 'test'
export const aliases = ''

export const builder = (option: any) => {
  Option.set('opt1', { desc: 'opt1 desc', default: 'val1', alias: 'o1'})
}

export const handler = async (argv: any) => {
  console.log('Hello world!')
}

Dynamicly register commands

As I tried, I can not provide the api in my mod, because Deno prevent dynamicly import module out of a mod, so you need to create the dynamicly import and register api in your mod.

I write an example code about this below, feel free to change in your way:

async function dynamicRegister() {
  const commandsDir = 'src/commands'
  const scannedCommands = []
  for (let entry of Deno.readDirSync(commandsDir)) {
    if (entry.isFile && path.extname(entry.name) == '.ts') {
      scannedCommands.push(entry)
    }
  }

  for (let entry of scannedCommands) {
    const command = await import(path.resolve(commandsDir, entry.name))
    registerCommand(path.basename(entry.name, '.ts'), command)
  }
}

await dynamicRegister()
