I don't split using branch. Because I didn't notice when I started.

I made the following changes:

• use pnpm to replace with npm
• use prettier as the code formatters but I didn't change code style.
• use es6 module syntax and rollup bundler.
• replace gulp with some modern tools and scripts

The commits are mess, so you can see this pull requests as a issue with its experiment.

You can edit by yourself, even close this pull request . It is up to you. This project has not been updated for a long time, so I want to make it again.
