Acconut / cedric

A simple vendoring tool for Go

cedric(1) is a vendoring tool for Go built with simplicity in mind. Its only purpose and functionality is to read dependencies from a package, download, and copy them into the vendor/ directory. This allows authors to use Go's vendoring system for importing external packages.

cedric's functionality includes:

• No additional configuration file for version locking or similar used
• No requirement on the Go vendor experiment by itself
• Scan packages and its subdirectories recursively
• Automatically add Git repositories as submodules
• Flat dependency tree

Installation

go get -u github.com/Acconut/cedric

Usage

cedric(1) will not download the dependencies on its own. Instead it outputs a Bash script which, when executed, will download and copy the external packages into the vendor directory. By default, it will scan the current package recursively (excluding vendor/ and other directories such as .git/).

$ bash -c "$(cedric)"

Example

$ cat <<EOF > main.go
package main

import (
        "github.com/fatih/color"
)

func main() {
        color.Cyan("Hello World!")
}
EOF

$ git init

$ bash -c "$(cedric)"

$ go run main.go
# Hello World!

$ tree -d
#.
