Extensions for the Notepadqq project found at: http://notepadqq.altervista.org/s/ If you can not see the extensions tab in the toolbar, open ~/.config/Notepadqq/Notepadqq.ini and add:
[Extensions]
RuntimeNodeJS=/usr/bin/nodejs
RuntimeNpm=/usr/bin/npm
node.js npm
These should be everything you need.
git clone git@github.com:qcerasmus/notepadqq-extensions.git
cd {notepadqq-extensions}/{extension you want to install}
{don't think this will be necessary} npm install notepadqq-api --save
node /usr/share/notepadqq/extension_tools/pack.js . npm
The last one will create a package {extension-name}-version.subversion.revision.nqqext
You can install the nqqext extension now.
