A little bit fast and modern Ruby version manager written in Rust
Features
- Pure Rust implementation not using
ruby-build - Cross-platform support (macOS, Linux)
- Works with
.ruby-versionfiles - Auto-Completion
Goals
- Blazing-Fast Ruby Installation - built with speed in mind
- Cross-Platform - works on macOS, Linux and (Windows)
Benchmark
eval "$(frum init)" runs about 6 times faster than eval "$(rbenv init -)".

Usage
Shell Setup
You need to run some shell commands before using frum. All you have to do is evaluate the output of frum init. Check out the following guides for the shell you use:
Bash
add the following to your .bashrc:
eval "$(frum init)"
Zsh
add the following to your .zshrc:
eval "$(frum init)"
Fish shell
create ~/.config/fish/conf.d/frum.fish add this line to it:
frum init | source
Options
- --log-level: The log level of frum commands [default: info] [possible values: quiet, info, error].
- --ruby-build-mirror: [default: https://cache.ruby-lang.org/pub/ruby].
- --frum-dir: The root directory of frum installations [default: $HOME/.frum]. You can set
frum-diras the$FRUM_DIRenvironment variable. I recommend that you use the environment variable if you want to use your customizedfrum-dirglobally.
Subcommands
- init: Sets environment variables for initializing frum.
- install: Installs the specified Ruby version.
- -l, --list: Lists the Ruby versions available to install.
- uninstall: Uninstall a specific Ruby version.
- versions: Lists installed Ruby versions.
- global: Sets the global Ruby version.
- local: Sets the current Ruby version.
Ruby configuration options
Options to configure Ruby can be passed to the frum install command.
$ frum install --with-openssl-dir=<ssl_dir> # Specify the OpenSSL directory

You can also specify many other options that will be listed when running ./configure -h.
