The Universal Binary Installer

When I say "universal", I mean it downloads binaries from GitHub releases.

When I say "binary", I mean it handles single-file executables like those created by most Go and Rust projects.

When I say "installer", I mean it plops the binary wherever you tell it to.

And finally, when I say "UBI", I don't mean "universal basic income", but that'd be nice too.

Installing It

You can install it by hand by downloading the latest release from the releases page.

There are also bootstrap install scripts (well, one script for Unix systems so far) that provide a half-assed implementation of ubi:

Linux and macOS

$> curl --silent --location \ https://raw.githubusercontent.com/houseabsolute/ubi/master/bootstrap/bootstrap-ubi.sh | sh

If you run this as a non-root user, it will install ubi into $HOME/bin. If run as root it installs it into /usr/local/bin.

Windows

I need some help with writing a Powershell script.

How to Use It

``` USAGE: ubi [FLAGS] [OPTIONS] --project

FLAGS: -d, --debug Enable debugging output -h, --help Prints help information -q, --quiet Suppresses most output -v, --verbose Enable verbose output -V, --version Prints version information

OPTIONS: -e, --exe The name of this project's executable. By default this is the same as the project name, so for houseabsolute/precious we look for precious or precious.exe. When running on Windows the ".exe" suffix will be addedas needed. -i, --in The directory in which the binary should be placed. Defaults to ./bin. -p, --project The project you want to install, like houseabsolute/precious or https://github.com/houseabsolute/precious. -t, --tag The tag to download. Defaults to the latest release. ```

Using a GitHub Token

If the GITHUB_TOKEN environment variable is set, then this will be used for all API calls. You will almost certainly need to do if you are using ubi in a CI environment that runs jobs frequently, as GitHub has a very low rate limit for anonymous API requests.

Why This Is Useful

With the rise of Go and Rust, it has become increasingly common for very useful tools like ripgrep to publish releases in the form of a tarball or zip file containing a single executable. Having a single tool capable of downloading the right binary for your platform is quite handy.

Yes, this can be done in half a dozen lines of shell on Unix systems, but do you know how to do the equivalent in Powershell? I don't. Seriously, I could use some help with this.

Once you have ubi installed, you can use it to install any of these many single-binary tools available on GitHub, on any supported platform.

Is This Better Than Installing from Source?

I think so. While you can of course use go or cargo to install these tools, that requires an entire language toolchain. Then you have to actually compile the tool, which may require many downloading and compiling dependencies. This is going to be a lot slower and more error prone than installing a binary.

Is This Better Than Installing from a deb/RPM/homebrew/chocolatey Package?

That's debatable. The big advantage of using ubi is that you can use the exact same tool on many platforms. The big disadvantage is that you don't get a full package that contains metadata (like a license file) or extras like shell completion files, nor can you easily uninstall it using a package manager.

And of course, not every tool has packages for every platform.
