快速开始

This guide gets you started with Tableau in Go with a simple working example.

Prerequisites #

• Go, any one of the three latest major releases of Go.
  • For installation instructions, see Go’s Getting Started guide.
• Protocol buffer compiler, protoc, version 3.
  • For installation instructions, see Protocol Buffer Compiler Installation.
• Go plugins for the protocol compiler:

  1. Install the protocol compiler plugins for Go using the following commands:

     go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.26
     

  2. Update your PATH so that the protoc compiler can find the plugins:

     export PATH="$PATH:$(go env GOPATH)/bin"
     

Get the example code #

The example code is part of the tableau/demo repo.

1. Download the repo as a zip file and unzip it, or clone the repo:

   git clone https://github.com/tableauio/demo
   

2. Change to the quick start example directory:

   cd demo/examples/helloworld
   

Run the example #

From the examples/helloworld directory:

1. Change dir to excel2proto, compile and execute:

   go run main.go
   

   Then proto files will be generated to examples/helloworld/proto.

2. Change dir to excel2conf, generate *.pb.go and then compile and execute:

   bash gen.sh
   go run main.go
   

   Then *.pb.go files will be generated to examples/helloworld/protoconf, and JSON files will be generated to examples/helloworld/excel2conf/_out.

Congratulations! You’ve just run a modern configuration converter application with Tableau.
