Improve help text/examples for updating versions?

[0xdevalias]

Looking at https://github.com/postmodern/ruby-versions/blob/master/ruby/stable.txt#L2 2.4.6 is included, but when I run ruby-install it's not listed:

⇒  ruby-install
Stable ruby versions:
  ruby:
    2.2.10
    2.3.8
    2.4.5
..snip..

Is there some way I can force my version to pull the latest list?

⇒  ruby-install --version
ruby-install: 0.7.0

Alternatively, maybe the version on brew is outdated?

⇒  brew info ruby-install
ruby-install: stable 0.7.0 (bottled), HEAD

Which seems to match the latest release: https://github.com/postmodern/ruby-install/releases/tag/v0.7.0

Looking at https://github.com/postmodern/ruby-install/blob/master/share/ruby-install/ruby-versions.sh#L6 ~it's trying to check against https://raw.githubusercontent.com/postmodern/ruby-versions/master, but when i try to view that in my browser I get a 400: Invalid request (though maybe that is just the base url that is used to fetch the specific files)~ I can see that https://raw.githubusercontent.com/postmodern/ruby-versions/master/ruby/versions.txt correctly lists 2.4.6

I can see that my local cache doesn't have it, which explains why it isn't showing up:

⇒  cat ~/.cache/ruby-install/ruby/versions.txt| grep '2.4'
2.2.4
2.4.0-preview1
2.4.0-preview2
2.4.0-preview3
2.4.0-rc1
2.4.0
2.4.1
2.4.2
2.4.3
2.4.4
2.4.5

Looking at https://github.com/postmodern/ruby-install/blob/master/bin/ruby-install#L12-L15 there appears to be a force update function, but that doesn't seem to be listed in ruby-install -h (usage ref)

I can see that --latest will set force_update https://github.com/postmodern/ruby-install/blob/master/share/ruby-install/ruby-install.sh#L186-L189 and I guess re-reading the help for it.. it's probably actually what I want.. -L, --latest Downloads the latest ruby versions and checksums

I wonder if it would be useful to include this check automatically sometimes (like how brew auto updates itself these days), and/or include an alias like --update or similar, or just call it out in the examples/help text more explicitly?

You should be able to fetch the latest versions from postmodern/ruby-versions with:

ruby-install --latest

Does 2.4.6 show up after a ruby-install --latest?

It does.. that was a brain fail on my part, thanks for pointing it out. Edited my original post as I discovered that (before I saw your post):

Any thoughts on tweaking the help text/examples/etc to call this out better?

I thought about naming --latest as --update, but ruby-install --update ruby seemed kind of confusing; whereas ruby-install --latest ruby reads better. --sync was also considered. My assumption was a user would see the news that a new ruby version was released, and then run ruby-install --latest ruby [2.X] to install the "latest" released version.

Convention for package managers (according to apt-get, brew, etc.) is to use xyz update to fetch the latest packages, and xyz upgrade abc to install a new version of a package.

My opinion is that ruby-install should fetch the latest versions by default and list them. Why would someone want to see a potentially out of date list of ruby versions?

If you prefer keeping the current behavior, I propose revising the README.md and ruby-install --help to the following:

---

List supported Rubies and their versions (from local cache):

$ ruby-install

Fetch latest supported Rubies and list their versions:

$ ruby-install --latest

Install the current stable version of Ruby (from local cache):

$ ruby-install ruby

Fetch and install the latest version of Ruby:

$ ruby-install --latest ruby

I've added -U,--update in 9196cc4 and adjusted the wording in the README in 14375a02ff9287b77e877e94483ef00acf09f1dc.
