go-template

Create go projects from templates

Concept

go-template stores templates locally by cloning them from a git repository. While not necessary, this is required to use management commands.

Each template contains a .go-template.yml which contains information like the name of the template, homepage, etc and metadata required to apply the template.

Cloning of the repositories is done by calls to git, so in order to have the management command working, your git installation has to be configured correctly.

Installation

Source code

go get livingit.de/code/go-template

Configuration

There is one global configuration, the storage. It is a directorty where the templates are stored and defaults to /.go-template. You can override it using the commandline, a ~/.go-template.yml containing the storage setting.

.go-template.yml

Placed in the root of the template repository this file enables go-template to use the repository as a template

project:
  name: "go-rest"                                                    # Name your template
  description: "rest service implementation inspired by Mat Ryer"    # A longer description
  author: "Sascha Andres"                                            # Your name or handle
  repository: "https://github.com/sascha-andres/go-rest"             # homepage/repository

transformation:
  templates:                                                         # List all files that are based on Go templates
    - README.md
  excluded-files:                                                    # List all files that shall not be part of new project
    - ".go-template.yml"
  renames:                                                           # rename files/folders
    - from: "go-rest"
      to: ""
  replacements:                                                      # Replace content in files, templates will not be treated
    - from: "go_rest"
      to: ""
    - from: "github.com/sascha-andres/go-rest/go-rest/cmd"
      to: "///cmd"
    - from: "github.com/sascha-andres/go-rest"
      to: "/"
    - from: "go-rest"
      to: ""

git: true                                                            # Initialize a git repository for new project

arguments:                                                           # List of arguments required to run template
  - Namespace

Usage

Repository management

Add a repository

go-template repo add --url <git-url>

Update all repositories

Iterate over all local repositories and issue a git pull

go-template repo update

Update a repository

Issue a git pull for a specific repository

go-template repo update --limit-to <name>

List all local repositories

Print out a tabular list of repositories installed locally

go-template repo list

Info for a repository

Print out information for a specific repository. Useful to learn about arguments required to run the template

go-template repo info --name <name>

Apply

go-template new --template <name> --name <project-name> --arguments [key=value],[key=value],...

Providing an argument more than one time will be considered an error
