Add custom command in the context menu

#1

Hello,

Somebody can confirm if it’ll be possible to add some customs commands in the right menu for sublime text 4 ?
I would like to add a shortcut in the right menu to create a random string (8 cars).

Thanks in advance for your help.

Thanks for your reply.
I succeed to create a short in the context menu.

[
  {
        "caption": "Custom",
        "id": "file",
        "children":
        [
            { "caption": "Chaine aléatoire sur 8 caractères", "command": "random_string", "args": {"length": 8}}
        ]
    }
]

I created a python script in the same folder to generate the random string :

import sublime
import sublime_plugin
import random
import string

class random_string(sublime_plugin.WindowCommand):
    def run(self, length=8):
        window = self.window
        letters = string.ascii_lowercase
        result_str = ''.join(random.choice(letters) for i in range(length))
        print("Random string of length", length, "is:", result_str)
        return result_str

I can see the message in the console, but I don’t find how to write the result inside the current opened file.

You can do that with a plugin such as the following:

import sublime
import sublime_plugin

import random
import string

class RandomStringCommand(sublime_plugin.TextCommand):
    def run(self, edit, length=8):
        letters = string.ascii_lowercase
        result = ''.join(random.choice(letters) for i in range(length))

        self.view.run_command('insert', {'characters': result})

There are a few ways to insert text, but the easiest one is to use the built in insert command, which will do the job and make sure that text is inserted at all curors, will replace selected text as expected, etc.

Your plugin used a WindowCommand, and while that could be used for something like this with some modifications, generally speaking you want to use a TextCommand for commands that are specific to files (whereas WindowCommand commands are specific to windows instead).

You can generate more random strings by setting letters to string.ascii_lowercase + string.ascii_uppercase + string.digits

Thanks, I updated my short code :slight_smile:

import sublime
import sublime_plugin
import random
import string
class random_string(sublime_plugin.TextCommand):
    def run(self, edit, length=8):
        if (length <= 0): return false
        letters = string.ascii_lowercase + string.ascii_uppercase
        result  = random.choice(letters)
        letters += string.digits        
        result  += ''.join(random.choice(letters) for i in range(length - 1))
        self.view.run_command('insert', {'characters': result})
