Usage

This project is still under development. Advice and PR are welcome! 😆

1. Install otfcc, Node.js and NPM (or Yarn).
2. Clone (or download) IBM Plex Mono.
3. Clone this repo and install all dependencies by run npm install (or yarn install).
4. Run node src/index.js -i IBM_PLEX_MONO_DIR (IBM_PLEX_MONO_DIR is the folder where IBM Plex Mono font files locate).
5. You will find output font files in build folder (you can use -o OUTPUT_FOLDER to specify another output folder).

P.S. If otfcc is not in your $PATH (for example, you just simply download pre-built binaries of otfcc on Windows), you can use -p OTFCC_FOLDER to specify the folder where otfcc (two executable files: otfccdump and otfccbuild) locates.
