Foreman

Foreman is a toolchain manager to help Roblox developers manage their installations of tools like Rojo, Remodel, Tarmac, DarkLua, StyLua, and Selene.

Foreman is inspired by rustup and asdf.

It's used in production across hundreds of engineers, but more feedback is welcome!

Installation

GitHub Releases

You can download pre-built Foreman releases for Windows, macOS, and Linux from the Releases page.

GitHub Actions

You can use the official setup-foreman action to install Foreman as part of your GitHub Actions workflow.

Upgrading

First, replace your current version of Foreman with the newest one from the GitHub releases. If you don't remember where you have put the executable, running where foreman on Windows or which foreman on macOS and Linux should help you find it.

The other step is to locate the bin directory created by foreman and delete the files there. It is as simple as opening .foreman/bin, which is located under the user directory (%homepath% on Windows or $HOME on macOS and Linux).

From Source

If you have Rust 1.53.0 or newer installed, you can also compile Foreman by installing it from crates.io:

cargo install foreman

To upgrade, re-run cargo install foreman and clean up the bin directory as described in the section just above.

Setup

Most users will want to do a bit of additional setup to begin using tools via foreman.

Path Configuration

On first run (try foreman list), Foreman will create a .foreman directory in your user folder (usually ~/.foreman on Unix systems, %USERPROFILE%/.foreman on Windows).

It's recommended that you add ~/.foreman/bin to your PATH to make the tools that Foreman installs for you accessible on your system. If you have tools installed via other mechanisms (for example, you may have previously installed rojo directly via cargo), ensure that ~/.foreman/bin is on your PATH before any other installation directories like .cargo/bin in order to make sure it takes precedence.

Authentication

To install tools from a private GitHub repository, Foreman supports authenticating with a Personal Access Token.

Use foreman github-auth to pass an authentication token to Foreman, or open ~/.foreman/auth.toml and follow the contained instructions.

Similarly, for projects hosted on a GitLab repository, use foreman gitlab-auth to pass an authentication token to Foreman, or open ~/.foreman/auth.toml.

Usage

Foreman downloads tools from GitHub or GitLab and references them by their user/repo name, like Roblox/foreman.

Configuration File

Foreman uses TOML for its configuration file. It simply takes a single tools entry and an enumeration of the tools you need, which looks like this:

[tools]
rojo = { github = "rojo-rbx/rojo", version = "7.0.0" }
darklua = { gitlab = "seaofvoices/darklua", version = "0.7.0" }

As you may already have noticed, the tool name is located at the left side of = and the right side contains the information necessary to download it. For GitHub tools, use github = "user/repo-name" and for GitLab, use gitlab = "user/repo-name".

Previously, foreman was only able to download tools from GitHub and the format used to be source = "rojo-rbx/rojo". For backward compatibility, foreman still supports this format.

System Tools

To start using Foreman to manage your system's default tools, create the file ~/.foreman/foreman.toml.

A Foreman config that lists Rojo could look like:

[tools]
rojo = { github = "rojo-rbx/rojo", version = "7.0.0" }

Run foreman install from any directory to have Foreman pick up and install the tools listed in your system's Foreman config.

Now, if you run rojo inside of a directory that doesn't specify its own version of Rojo, Foreman will run the most recent 0.5.x release for you!

Project Tools

Managing a project's tools with Foreman is similar to managing system tools. Just create a foreman.toml file in the root of your project.

A Foreman config that lists Remodel might look like this:

[tools]
remodel = { github = "rojo-rbx/remodel", version = "0.9.1" }

Run foreman install to tell Foreman to install any new binaries from this config file.

When inside this directory, the remodel command will run the latest 0.6.x release of Remodel installed on your system.

Troubleshooting

Foreman is a work in progress tool and has some known issues. Check out the issue tracker for known bugs.

If you have issues with configuration, you can delete ~/.foreman to delete all cached data and start from scratch. This directory contains all of Foreman's installed tools and configuration.

Bad CPU type Error

If you're using foreman version 1.0.4 or older on a non-M1 Mac, you may have encounter an error that looks like this:

an error happened trying to run `github.com/some-org/some-tool@^1.2.3` at `/Users/some-user/.foreman/tools/some-org__some-tool-1.2.3` (this is an error in Foreman): Bad CPU type in executable (os error 86)

In this case, your foreman installation has mistakenly downloaded an incompatible version of the tool binary due to an error in the binary file selection logic.

To fix this error, take the following steps:

1. Upgrade your version of foreman per the instructions above.
2. Delete the ~/.foreman/tool-cache.json file and the ~/.foreman/tools/ folder (and its contents), as well as the ~/.foreman/bin folder (as described in the Upgrading section above). This should remove any invalid binaries that foreman has cached.
3. Run foreman install to redownload all relevant tools.

Your downloaded tools should now work correctly.
