write_feed_dangerously usage about partridge

[invisiblefunnel]

Hi @cjer. I recommend using ptg.writers.extract_feed, instead of using write_feed_dangerously.

inpath = 'mygtfs.zip'
outpath = 'mygtfs-pruned.zip'
agency_ids = ['2', '4']

ptg.writers.extract_feed(inpath, outpath, {
    {'routes.txt': {'agency_id': agency_ids}}
})

feed = ptg.feed(outpath)

Does that work for your use case?

Hey! that seems to work great!

docs anyone? :)

I recently added extract_feed to the docs under "Extracting a new feed" in the Usage section: https://github.com/remix/partridge#usage.
