A simple command-line [Pinboard.in][] client:

pin-cushion [verb] [arguments]
pin-cushion posts/recent
pin-cushion posts/suggest --url "http://www.ponylang.org"

pb-rename() {
   pin-cushion tags/rename --old "$1" --new "$2"
}

You get the idea. To use it, you must first record [your authentication token][auth] for the API:

npm install -g pin-cushion
pin-cushion --auth elliottcable:DEADBEEF1234567890

This only provides abstracted access to the Pinboard API as defined on their site:

https://pinboard.in/api

Any Pinboard API method described there may be passed as the verb; and all described arguments are accepted as command-line flags. These are not stored in this library; as your command-line instructions are simply converted directly to API calls; so this tool probably doesn't need much in the form of maintenance. :P

[Pinboard.in]: <https://pinboard.in/ [auth]: https://pinboard.in/settings/password

If not explicitly passed a --format parameter, then pin-cushion will spit out a formatted object-description of the response, intended for human consumption. If a format is explicitly provided, then the response from the server will be printed, unmodified; this is particularly useful with the jq command-line JSON manipulation tool:

pin-cushion posts/recent --format=json | jq                      # Simply pretty-print
pin-cushion posts/recent --format=json | jq '.posts[] | .href'   # Extract URLs of recent pins

This obviously lends itself to constructing complex shell pipes. Personally, I suggest aliasing this:

pc() { pin-cushion "$1" --format=json "$@" ;}
