Install and use Retool, Protobuf while experimenting Twirp

On this post I have added some of the logs while experimenting Twirp ,a simple RPC framework built on protobuf.

On such Error :

esumits-MacBook-Pro:haberdasher esumit$ protoc –proto_path=/Users/esumit/go/src:. –twirp_out=. –go_out=. service.proto

protoc-gen-twirp: program not found or is not executable

–twirp_out: protoc-gen-twirp: Plugin failed with status code 1.

Make sure propers paths are set up in .bash_profile

esumits-MacBook-Pro:~ esumit$ retool

usage: retool (add | remove | upgrade | sync | do | build | help)

use retool with a subcommand:

add will add a tool

remove will remove a tool

upgrade will upgrade a tool

sync will synchronize your _tools with tools.json, downloading if necessary

build will compile all the tools in _tools

do will run stuff using your installed tools

help [command] will describe a command in more detail

version will print the installed version of retool

esumits-MacBook-Pro:~ esumit$ retool add github.com/golang/protobuf/protoc-gen-go master

retool: downloading github.com/golang/protobuf/protoc-gen-go

retool: setting version for github.com/golang/protobuf/protoc-gen-go

retool: parsing revision “master”

retool: parsed as “3a3da3a4e26776cc22a79ef46d5d58477532dede”

retool: installing github.com/golang/protobuf/protoc-gen-go

esumits-MacBook-Pro:~ esumit$

esumits-MacBook-Pro:~ esumit$

esumits-MacBook-Pro:~ esumit$ retool add github.com/twitchtv/twirp/protoc-gen-twirp master

retool: downloading github.com/golang/protobuf/protoc-gen-go

retool: setting version for github.com/golang/protobuf/protoc-gen-go

retool: downloading github.com/twitchtv/twirp/protoc-gen-twirp

retool: setting version for github.com/twitchtv/twirp/protoc-gen-twirp

retool: parsing revision “master”

retool: parsed as “1b8455b42110feb46a56aeec1ea0020067f46b11”

retool: installing github.com/golang/protobuf/protoc-gen-go

retool: installing github.com/twitchtv/twirp/protoc-gen-twirp

esumits-MacBook-Pro:~ esumit$

 

Finally this Works :

esumits-MacBook-Pro:haberdasher esumit$ protoc –proto_path=$GOPATH/src:. –twirp_out=. –go_out=. service.proto

esumits-MacBook-Pro:haberdasher esumit$ ls

‘ _tools service.pb.go service.proto service.twirp.go

esumits-MacBook-Pro:haberdasher esumit$
