Go Mod Private

A simple helper toolkit to help development with Private Git Server using Golang Module. It allows you to use Git Private Server for your vendor. You can also use gomp get just as go get.

Note : Currently gomp didn't support ./... operation.

Installation

Before installing gomp, you have to make sure that you have git installed on your system. To install gomp command line interface, simply use syntax below :

go get github.com/firmanmm/go-mod-private/cmd/gomp

Usage

If you don't know what this tool does, simply add -h when using gomp cli.

Example :

$ gomp -h
NAME:
   GoModPrivate - Go Module for Private Git Server Repository

USAGE:
   gomp.exe [global options] command [command options] [arguments...]

VERSION:
   0.0.0

DESCRIPTION:
   Allow you to use Git Private Server as your source dependency while using Go Module

AUTHOR:
   Firman "Rendoru" Maulana 

COMMANDS:
   get             Perform Go Get operation, will switch to git clone and git pull if a matching SSH Credential has been registered
   add_credential  Add credential to be used for [get] command
   sync            Synchronize vendor.gomp and go.mod to mod.gomp
   help, h         Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --gomp value   Read from given gomp file (default: "mod.gomp")
   --help, -h     show help
   --version, -v  print the version

Getting Package

If you want to use gomp just like using go get you just need to replace go get with gomp get. Syntax :

$ gomp get [arguments...]

Example :

$ gomp get github.com/firmanmm/suberror

gomp will try to scan your mod.gomp file to determine any SshCredential that match your requested package. gomp will match with the longest matching SshCredential if there are multiple credentials that can be used by your request. Upon match, gomp will perform git clone internally to get your desired package. If there are no credentials that match your request, gomp will use go get to get your request.

How it works

• gomp try to find any matching credential
  • If nothing match, gomp will use go get
• gomp will perform git clone using your SshCredentials instead go get
• gomp will add the cloned repository to vendor.gomp
• gomp will then update your go.mod to use files from vendor.gomp. It will only update your gomp get'ed repository
• gomp will keep track of your private repository in mod.gomp

Adding Credentials

gomp support adding credentials to mod.gomp via CLI. This way, you don't have to edit your mod.gomp manually. Syntax :

$ gomp add_credential --host=[Required] --user=[Required] --base=[Optional] --pattern=[Optional]

• --host : Your target host. Required
• --user : Your target user. Required
• --base : Base path for searching for package.
• --pattern : Will be used to match your requested package with this credential. Example :

$ gomp add_credential --host=rendoru.com --user=someone --base=/home/someone --pattern="rendoru.com(.*)"

Synchronizing

gomp can automatically synchronize vendor.gomp and go.mod with the mod.gomp. This way you don't have to manually get them one by one. Syntax :

$ gomp sync
