GRM: A tool for fetching the latest release assets from public GitHub Repositories

Installation

go get -u github.com/kowala-tech/github-release-manager/cmd/grm

Usage

To get the latest tarball for a repository, run

grm my-user/my-repo

This will download the latest release to the disk to a file in the current directory named after the tag, if there is a release. A file called .grm/my-user/my-repo will be created on the disk with the latest tag name in it, and the grm command will return 0.

If there is an existing file called .grm/my-user/my-repo that contains the current name, then nothing will be downloaded and grm will return 1.

This can then be used in shell scripts and Makefiles to trigger actions when the script is run:

#!/bin/bash

echo "Making sure my-repo is up to date"
grm -o my-repo-lastest.tar my-user/my-repo

if ! [ $? -eq 1 ]; then 
    echo "The repo has changed or been installed for the first time"
    tar -xvf my-repo-latest.tar /some/path
else 
    echo "The repo as already up to date`
fi
