A little bit fast and modern Ruby version manager written in Rust

Closes #50

This PR adds a configure_opts arg that gets passed through to the ./configure call unmodified.

This uses a TrailingVarArg to collect options in a multiple arg. It supports the following two forms:

frum install 3.0.1 --with-jemalloc # only when no flags are specified
frum install 3.0.1 -- --with-jemalloc # always

I'm opening this as a draft PR for now to get feedback on two questions:

1. Are you ok with this approach @TaKO8Ki? I originally just added a with-jemalloc arg but this has the potential for becoming unwieldy so It may make more sense to allow for arbitrary arguments to be passed through.
2. Should we remove the dedicated with-openssl-dir option and handle it through the same mechanism?

Once we decided on this I'll finish off this PR and fix the tests (they will fail for the completions alone).

changelog: Add configure_opts to pass through to ./configure.

Overview

When using command -v, I noticed Frum is pointing to temporary paths for all Ruby related binaries. I assume this is a bug?

Steps to Recreate

brew install frum

export FRUM_DIR="$HOME/.cache/frum"
eval "$(frum init)"

frum install 3.0.2
frum global 3.0.2
gem install pennyworth

# Notice the following paths all use temporary directories instead of the Frum cache as defined above.
command -v ruby        # => /var/folders/j1/szrwbp9d1jg351ghw4f7bcym0000gn/T/frum_1956_1627218393720/bin/ruby
command -v pennyworth  # => /var/folders/j1/szrwbp9d1jg351ghw4f7bcym0000gn/T/frum_1956_1627218393720/bin/pennyworth

Desired Behavior

I would expect to see the full path to where the Frum cache is located. So something more along these lines, for example:

$HOME/.cache/frum/versions/3.0.2/lib/ruby/gems/3.0.0/gems/pennyworth-11.1.1/bin

Environment

• Operating System: macOS 11.5 (20G71)
• Frum: 0.1.0

Overview

Would it be possible to support automatic version switching much like chruby's auto-switching?

Screenshots/Screencasts

The following captures the problem of having to manually switch Ruby versions when switching between projects:

https://user-images.githubusercontent.com/50245/126048754-17938534-9ac8-4e32-ae65-54ef068568aa.mp4

Steps to Recreate

Run the following:

frum --frum-dir "$HOME/.cache/frum" install 3.0.0
frum --frum-dir "$HOME/.cache/frum" install 3.0.2
printf "%s\n" "3.0.2" > $HOME/.ruby-version
mkdir zero
printf "%s\n" "3.0.0" > "zero/.ruby-version"
cd zero
cd ..
cd zero

Notice that Frum never detects the correct version (global versus local).

Desired Behavior

As shown in the screencast and steps above, Frum doesn't distinguish between the global, system-wide Ruby version of 3.0.2 versus the local project version of 3.0.0. You have to manually set the Ruby version you desire each time you switch a directory.

Environment

• Operating System: macOS 11.4 (20F71)
• Frum: 0.1.0

Issue description

I've symlinked Ruby minor versions in $FRUM_DIR/aliases/, e.g. 3.0 → 3.0.2. Unfortunately, when using the aliases in a .ruby-version file, they don't seem to do anything, and frum reverts to the global version.

My FRUM_DIR is set to ~/.cache/frum/.

Steps to reproduce the issue

1. Create new folder, inside create a .ruby-version version file containing an alias version.
2. Change out of the folder, then back in to that folder.

What's the expected result?

When changing into alias-test/, frum resolves the alias 2.7 found in the .ruby-version file to 2.7.4 and sets Ruby 2.7.4.

What's the actual result?

When changing into alias-test/, frum doesn't resolve the alias 2.7 and instead falls back to my globally set Ruby 3.0.2.

Screenshot:

Note the Ruby version in the last prompt.

Applied Clippy lints with cargo clippy --fix and manually refactored some to make Clippy report 0 warnings :)

Notes:

• will every supported shell have completions? if not, changing signature of customize_completions might've been a bad move.

Super excited to try out Frum. I'm having trouble installing rubies < 3

On a fresh install of Montery - Intel chip:

Installing 3.0.2 works just fine.

Installing 2.7.3 or 2.7.4 fails with cannot load such file -- openssl. I have tried different versions of openssl. I have tried with and without the --openssl-dir flag. The factory openssl is:

$ openssl
OpenSSL> version
LibreSSL 2.8.3

The error I get is:

Using macOS Big Sur 11.5.2 (2019 MBP) I installed frum via homebrew, ran frum install 3.0.2, and tried installing a ruby gem (colorls) and received an error about OpenSSL not being available.

$ gem install colorls
ERROR:  While executing gem ... (Gem::Exception)
    OpenSSL is not available. Install OpenSSL and rebuild Ruby (preferred) or use non-HTTPS sources

I see that you can specify the OpenSSL directory but I'm not sure exactly how this should be used. If Big Sur has OpenSSL at /usr/bin/openssl should I be using that? Installing 3.0.2 with --with-openssl-dir=/usr/bin/openssl didn't work. I'm not sure what might be going wrong here.

The gem error says to install OpenSSL and rebuild Ruby. I'm able to install OpenSSL (brew install openssl) but I'm not sure how to rebuild ruby with frum.

Is something wrong here or is am I just missing some foundational Ruby knowledge here that is preventing me from getting this to work?

This PR replaces the custom code for finding the number of available CPU cores with the num_cpus crate. This should get us a little closer to Windows support as the current code did not take Windows into account. I plan to eventually also look into other Windows-related problems even though my main development OS is Linux.

changelog:

• Add num_cpus crate

Hi @TaKO8Ki, it would be nice if frum had an option to build with jemalloc, since it is a common optimization flag. Alternatively frum could allow to pass any options when building ruby using the syntax below (used in ruby-install):

frum install 3.0.1 -- --with-jemalloc

I love it so far, just needs a quiet option. I'm not a fan of seeing the error message about not finding a ruby-version file every time I cd to a directory.

Just a FYI, I'm on FreeBSD 13, and it's working great. Thank you for your work.

Morning,

I'm unable to install 3.2 on my M1 mac this morning. I've tried various ruby-build solutions with no luck. I think the project doesn't use ruby-build though.

Here's my output when making sure libyaml is installed too (https://github.com/rbenv/ruby-build/discussions/2118#discussioncomment-4505182).

To eliminate this warning, please install libyaml and reinstall your ruby.
uh-oh! RDoc had a problem:
cannot load such file -- psych

run with --debug for full backtrace
make: *** [rdoc] Error 1

Anyone have any tips? Do I need to use a RUBY_OPTS explicitly to point to libyaml

Currently some projects like logstash and many other uses JRuby, but rvm is not that optimized and fast as Frum

Hope you the best! This is a really nice and usefull project

If it's poosible I can start supporting that feature if needed.

Hi!

I have a MacBook Pro M1, and after successfully installing frum I "install" gems, but they are not "available" at some point.

Something similar happened with rails and other stuff. I may be misunderstanding a concept around frum but I cannot get it from the docs.

Any ideas?

I've googled this issue for hours now and give up. I've tried all the solutions I could find online yet I am unable to use frum to install any Ruby versions. A log is below.
