Ok, correcting my previous post –
While working on an other project, I am migrating the plugin management to composer – which then allow to manage both regular update and update from custom repo.
Actually – I just checked wp-client – which was suggested by somebody else on this forum – looks like a nice option too – especially has some integration with woocommerce membership – which is a very good idea…
Came here to to suggest a similar idea – but in terms of technical I would suggest a very simple idea.
We could simply use WP CLI
And maintain a list of installed plugins URLs from GPLDL – and the run a simple shell script
yet unsure how to handle the required authentification (maybe someone will get some ideas by reading the doc of s2membership – maybe i will – when I coin the time for it somewhere)
have a great day everybody!
