@ -37,31 +37,10 @@ This awesome script was written by [IlyaSkriblovsky](https://github.com/IlyaSkri
they are available via brew (`brew install fontforge`).
## Using the Script ##
1. Move/copy the font you want to ligaturize into `input-fonts/`
1. Move/copy the font you want to ligaturize into `input-fonts/` (or somewhere else convenient).
2. Edit `ligatures.py` to disable any ligatures you don't want.
3. Run the script: `$ fontforge -lang=py ligaturize.py`
4. You'll be prompted for the name of the font, and the name for the generated font.
Example:
```shell
❯ fontforge -lang=py ligaturize.py
...
Enter the source font filename (including extension): RobotoMono-Regular.ttf
Enter a name for your ligaturized font -- or press ENTER to use the same name: <PRESS ENTER>
...
Generated ligaturized font Roboto Mono L in ligaturized-fonts/RobotoMono.ttf
```
```shell
❯ fontforge -lang=py ligaturize.py
...
Enter the source font filename (including extension): RobotoMono-Regular.ttf
Enter a name for your ligaturized font -- or press ENTER to use the same name: RobotoMonoL
...
Generated ligaturized font Roboto Mono L in ligaturized-fonts/RobotoMonoL.ttf
```
If you don't provide a name for the new font, it will have the same name as the input font.
3. Run the script: `$ fontforge -lang=py ligaturize.py <INPUT> <OUTPUT>`, e.g. `$ fontforge -lang=py ligaturize.py input-fonts/Cousine-Regular.ttf output-fonts/CousineLigaturized-Regular.ttf`
