I already posted this in the MPU forums, but I thought maybe this community might reach a few more people who are interested. I made a language plugin for the Atom text editor to add syntax highlighting and snippets when editing Bunch files. If you use Bunch and are editing Bunch files a lot, it might be nice to have the proper syntax highlighting. You can install the package here: language-bunch. I also wrote about it here: Atom package for bunch syntax published | Henry’s Site
If anyone does try it out, it is probably not perfect so feel free to let me know if there is anything weird about the highlighting.
