Now I'm in favour of anything that makes my life easier so I decided to take np and enhance it with some tasks I routinely do when publishing new plugins. My first pass at it is a new package called pluginpub which is a copy of np that I eventually hope to change to depend on np instead.
The main difference is that it:
It now automates a lot of stuff I used to do manually into a single command. Installation is simple, you run:
npm install pluginpub --save-dev
The command takes only one argument and that is the version of the plugin. If you don't pass in a valid semver then the command will fail.
Anyway, it make or may not be of use to you. Feel free to try it out and report any issues on the github page. Next steps are publishing a proper README and adding the auto-generation of a CHANGELOG file which is another manual step I hate doing when releasing a plugin.
