dk-curl

#!/usr/bin/env bash
# dk-curl — curl against the LOCAL data-kitchen pod, with the gate token attached
# so requests pass the bundled server's gate (electron-config/gate.cjs). Lets you
# read and write the running pod from the shell exactly as an app would, without
# weakening the gate — it just presents the same token the app injects.
#
#   dk-curl [curl options...] <path-or-url>
#
# The LAST argument is the target:
#   /dk-pod/…  or  dk-pod/…  or  ./dk-pod/…   → resolved against DK_BASE
#   http(s)://…                                → used as-is
# DK_BASE defaults to http://localhost:8000 (the routed origin — the real path,
# router → CSS). Set DK_BASE=http://localhost:8010 to hit the CSS pod server
# directly. Everything else is passed straight through to curl, so all of curl's
# flags work (-X, -H, -d, --data-binary @file, -i, -I, -o, …).
#
# Examples:
#   dk-curl /dk-pod/profile/card
#   dk-curl -i /dk-pod/dk/data/data-kitchen-settings.ttl
#   dk-curl -X PUT -H 'content-type: text/turtle' --data-binary @note.ttl /dk-pod/dk/scratch/note.ttl
#   echo '<a> <b> <c>.' | dk-curl -X PUT -H 'content-type: text/turtle' --data-binary @- /dk-pod/x.ttl
#   dk-curl -X DELETE /dk-pod/dk/scratch/note.ttl
#   DK_BASE=http://localhost:8010 dk-curl /dk-pod/dk/data/data-kitchen-settings.ttl
