regen-gapic.sh

#!/bin/bash

# This script generates all GAPIC clients in this repo.
# One-time setup:
#   cd path/to/googleapis # https://github.com/googleapis/googleapis
#   virtualenv env
#   . env/bin/activate
#   pip install googleapis-artman
#   deactivate
#
# Regenerate:
#   cd path/to/googleapis
#   . env/bin/activate
#   $GOPATH/src/cloud.google.com/go/regen-gapic.sh
#   deactivate
#
# Being in googleapis directory is important;
# that's where we find YAML files and where artman puts the "artman-genfiles" directory.
#
# NOTE: This script does not generate the "raw" gRPC client found in google.golang.org/genproto.
# To do that, use the regen.sh script in the genproto repo instead.
