I was (perhaps quite naively) expecting people would publish their own custom filters for the good of the whole community. Maybe we could see the rise of new creative uses of peneira.
In the past, I was a user of the venerable unite plugin for Vim, and it was great (a source of inspiration for peneira actually). One of the most interesting things about it was that people started writing 3rd party integrations for it, increasing its original capabilities.
Since peneira’s API is way simpler than unite’s, my expectations were that we could see new filters being published by the community.
That’s why I took the responsibility to write some more complicated filters myself, like peneira-symbols (my favorite) and peneira-lines, and leave easier-to-write ones (like, say, hypothetical peneira-buffers and peneira-grep) as exercises to the community.
I don’t know… it’s not clear to me why people didn’t do it. Perhaps it’s because vim user base is way bigger than ours; or perhaps our culture doesn’t favor working as a united and strong community as much as I would like.
But there’s still time! If you want to publish it (and maybe other new filters) yourself, I would be happy to guide you in the implementation and to link the project in the README of peneira.
