Installing hTools3

hTools3 is packaged and distributed as a RoboFont extension.

Installing with Mechanic

It is recommended to install hTools3 using Mechanic, so it can automatically check for updates and install them.

  1. After acquiring a license, you will receive a hTools3.mechanic file per email.
  2. Go to the Mechanic extension’s settings.
  3. Use the plus button to add the .mechanic file to the list of Single Extension Items.

Installing manually

The hTools3 extension can also be installed manually if you have the extension package.

Simply double-click the file hTools3.roboFontExt to have it installed in RoboFont.


If you install hTools3 manually, you will not be notified automatically about updates!

Installing from source

hTools3 can be used directly from the source code if you have access to the repository.

This mode allows developers to make changes to the code while using and testing the tools in RoboFont.

  1. Clone the repository using git clone (recommended) or download the source code.
  2. In the RoboFont Preferences window, go to Extensions > Start Up Scripts.
  3. Add the file hTools3/Lib/ to the list of start-up scripts.
  4. Save the settings and restart RoboFont – hTools3 will now appear in the main menu.
