Add an External Tool

Open Preferences → Tools → External Tools and add a new tool with these options:

• Program: path to the exec file (usually simply optimizt)
• Arguments: desired ones, but use $FilePath$ to pass Optimizt the path of the selected file or directory
• Working Directory: $ContentRoot$
• Synchronize files after execution: ✔️

Set other options at your discretion. For example:

As you see on the screenshot above, you may add several “external tools” with the different options passed.

How to use

Run the tool through the context menu on a file or directory:

Shortcuts

To add shortcuts for the added tool go to Preferences → Keymap → External Tools:

Add Task

Run >Tasks: Open User Tasks from the Command Palette.

In an open file, add new tasks to the tasks array, for example:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "optimizt: Optimize Image",
      "type": "shell",
      "command": "optimizt",
      "args": [
        "--verbose",
        {
          "value": "${file}",
          "quoting": "strong"
        }
      ],
      "presentation": {
        "echo": false,
        "showReuseMessage": false,
        "clear": true
      }
    },
    {
      "label": "optimizt: Optimize Image (lossless)",
      "type": "shell",
      "command": "optimizt",
      "args": [
        "--lossless",
        "--verbose",
        {
          "value": "${file}",
          "quoting": "strong"
        }
      ],
      "presentation": {
        "echo": false,
        "showReuseMessage": false,
        "clear": true
      }
    },
    {
      "label": "optimizt: Create WebP",
      "type": "shell",
      "command": "optimizt",
      "args": [
        "--webp",
        "--verbose",
        {
          "value": "${file}",
          "quoting": "strong"
        }
      ],
      "presentation": {
        "echo": false,
        "showReuseMessage": false,
        "clear": true
      }
    },
    {
      "label": "optimizt: Create WebP (lossless)",
      "type": "shell",
      "command": "optimizt",
      "args": [
        "--webp",
        "--lossless",
        "--verbose",
        {
          "value": "${file}",
          "quoting": "strong"
        }
      ],
      "presentation": {
        "echo": false,
        "showReuseMessage": false,
        "clear": true
      }
    }
  ]
}

How to use

1. Open the file for processing using Optimizt, it should be in the active tab.
2. Run >Tasks: Run Task from the Command Palette.
3. Select the required task.

Shortcuts

You can add shortcuts for a specific task by run >Preferences: Open Keyboard Shortcuts (JSON) from the Command Palette.

An example of adding a hotkey to run the "optimizt: Optimize Image (lossless)" task:

// Place your key bindings in this file to override the defaults
[
  {
    "key": "ctrl+l",
    "command": "workbench.action.tasks.runTask",
    "args": "optimizt: Optimize Image (lossless)"
  }
]

You’ll find the user settings directory in one of the following paths:

• macOS: ~/Library/Application Support/Sublime Text 3/Packages/User
• Linux: ~/.config/sublime-text-3/Packages/User
• Windows: %APPDATA%\Sublime Text 3\Packages\User

Add plugin

Inside the settings directory create a file optimizt.py with the following content:

import os
import sublime
import sublime_plugin

optimizt = "~/.nodenv/shims/optimizt"

class OptimiztCommand(sublime_plugin.WindowCommand):
  def run(self, paths=[], options=""):
    if len(paths) < 1:
      return

    safe_paths = ["\"" + i + "\"" for i in paths]
    shell_cmd = optimizt + " " + options + " " + " ".join(safe_paths)
    cwd = os.path.dirname(paths[0])

    self.window.run_command("exec", {
      "shell_cmd": shell_cmd,
      "working_dir": cwd
    })

Specify path to executable inside optimizt variable, this path can be obtained by running command -v optimizt (on *nix) or where optimizt (on Windows).

Integrate the plugin into the sidebar context menu

Inside the settings directory create a file Side Bar.sublime-menu with the following content:

[
    {
        "caption": "Optimizt",
        "children": [
          {
              "caption": "Optimize Images",
              "command": "optimizt",
              "args": {
                "paths": [],
                "options": "--verbose"
              }
          },
          {
              "caption": "Optimize Images (lossless)",
              "command": "optimizt",
              "args": {
                "paths": [],
                "options": "--lossless --verbose"
              }
          },
          {
              "caption": "Create WebP",
              "command": "optimizt",
              "args": {
                "paths": [],
                "options": "--webp --verbose"
              }
          },
          {
              "caption": "Create WebP (lossless)",
              "command": "optimizt",
              "args": {
                "paths": [],
                "options": "--webp --lossless --verbose"
              }
          }
        ]
    }
]

How to use

Run the tool through the context menu on a file or directory:
