BARRIER - require "rubygems"

ruby 1.9.2p180 Windows 7

Rubygems is included in ruby 1.9.

Because it's included, I expect that it will work out-of-the-box,
without the need to use

ruby -rubygems myscript.rb

and especially not

require "rubygems"

within *.rb files

···

-

The default-library-system which is included in the language, should
be *enabled* by default, thus a user can simply click on the files and
they start correctly, without the (logically false) need to have
"require librarysystem" within the files.

What step do I have to take, in order to activate rubygems as the
default library system (thus I can start .rb files without having to
require rubygems)?

Or you could try using the well documented RUBYOPT shell variable to
set the value RUBYOPT=rubygems

The only barrier here is that you didn't read the rubygems user guide
which is available on the internet. It even explains how to do this on
windows if you should be do hampered.

Does it not for you?

It works.

And in my file, I've removed "require 'rubygems' " now, and it works,
too (to my surprise).

But I'm sure it did not. After I installed via the "one-click-
installer", I had to use "require 'rubygems' " in order to make it
work.

I've now uninstalled everything including the gems, and reinstalled:

It works again.

I can't recreate it on this machine anymore.

If not can you give us some more
information, such as a simple demo that reproduces the issue?

It was really not much more than:

require 'rubygems' #add this, thus files can be started with double-
click on windows-explorer
require 'sinatra'
require 'json'

#some code to test rest & json

There is no such thing as One-Click Installer, is RubyInstaller

Ruby 1.9.1 and 1.9.2 remove the need for require "rubygems"

If you can't replicate it, then it didn't happen.

Has nothing to do with your machine, it works since long time ago, we
worked really hard to ensure that was for everybody.

It was really not much more than:

require 'rubygems' #add this, thus files can be started with double-
click on windows-explorer

Please note that you mentioned "One-Click Installer" but also
mentioned 1.9.2

RubyInstaller do not associate with .rb and .rbw files by default, you
need to check these options.

If you had a previous "One-Click Installer" (1.8.6 or older) and that
was associated with .rb files, that could explain why you needed
require "rubygems".

Confirmed, RubyInstaller

Ruby 1.9.1 and 1.9.2 remove the need for require "rubygems"

ok

It happened, just don't know the cause.

Please note that you mentioned "One-Click Installer" but also
mentioned 1.9.2

RubyInstaller do not associate with .rb and .rbw files by default, you
need to check these options.

I see, possibly this should be enabled by default (a knowledgeable
user will take action and disable if he needs so)

If you had a previous "One-Click Installer" (1.8.6 or older) and that
was associated with .rb files, that could explain why you needed
require "rubygems".

There is a possibility that this was the case.

One other possible influence could be the Kommodo IDE.

Anyway, if you say that this is a solved issue, than I consider it
closed.

btw:

Thank you for this RubyInstaller, makes things very easy.

That would be my guess as well. If you installed 1.8.6 from the (now
discontinued) one click installer, and later installed 1.9.2 via Ruby
Installer, by default it didn't associate the *.rb files with the new
installation, so when you ran from the command line you were using 1.9.2
as intended, but double clicking the file ran it on 1.8.6.

Defaults like file associations and editors are very subjective.

This is how RubyInstaller stand about that:

http://groups.google.com/group/rubyinstaller/msg/34dd829ebe0e4567

Want it different, build your installer and name it IlliasInstaller.

Something more constructive than that is what RailsInstaller project
did.

[...] - (expanding issue, getting personal)

No need to get personal or to extend the issue, it's very simple:

The fundamental user expectation is that it works out-of-the-box,
without any intervention.

And this is the major requirement to an installer.

Usually there is a choice, something like:

Default Installation
Custom Installation

"Default Installation" does not mean "I don't touch anything".

It means "I take the necessary actions to make the product running on
this machine".

If a user wants to have more control over the installation, he selects
"Custom installation".

(...) (some babbling about getting personal)

The fundamental user expectation is that it works out-of-the-box,
without any intervention.

Oh, you mean magical, like an automated install? Or probably you mean
unattended installation, that is when there is no user intervention.

The fundamentals are: when I install something, I don't want it mess
with my existing stuff.

If you actually install stuff on Windows, you will know how counter
productive is when you install something to try out and it changes all
your defaults.

Usually there is a choice, something like:
(...) (babbling and giving unsolicited advice on UX and installers)

What this does is hide the actions in two obscure items that newcomers
will not know what it means. Default installation doesn't say
anything, Neither does custom.

Right now the installers show in one single screen all your options,
which if users actually READ will be able to get what they want from
the installation.

"Another reason to streamline setup is that inexperienced users
sometimes overanalyze options, fearing that a wrong choice could be
irreversible or destructive. Forcing users to make decisions about
things they don't understand or care about can make them feel anxious,
incompetent, and even frustrated. Not a good first impression. It is
better just to get them going quickly, feeling comfortable and
confident as they explore the features in your program, and making
better decisions about feature options at that time."

Standard Setup, Custom Setup, that is adding too much noise. Also, an
standard setup should not alter the user environment.

RubyInstaller provides an access to the command prompt, "Start Command
Prompt with Ruby", which is located inside the Program menu, the place
newcomers will check as soon the installed something.

If you're savvy enough to attempt to use the default command prompt
that means you know about "Add Ruby to your PATH" option, which you
should have checked.

"Scope pages (typical, custom, or minimum)

Prefer to eliminate this page. Assume that most users want the typical
setup experience (and design that experience so that it works well for
most users)."

Yeah, code, that thing that make things work.

Here is RubyInstaller repository:

Bet you something: if you contribute "something" instead of continuous
non-constructive criticism, I'll happily apply to the project. After
all, we all will benefit.

To the above statement you will argue that you have nothing to prove
me, which will result in prove my point: your complete lack of
technical skills.

So, I challenge you for once and for all *do* something instead of
flood with criticism. Change start on you.

Until then, bye.

What you call "criticism" is basically detecting issues like
weaknesses, flaws, barriers, inconsistencies, defects.

This is my main expertise, or an inborn talent and tendency (or even a
"curse").

If spotting the issues leads to change, then this is a constructive
criticism, a contribution.

If I make additionally implementation / architectural suggestions,
then it's design work.

If there is much change-resistance (e.g. from the typical "freak-
show", the self-declared "community police" or simply by one crazy-
gone individual who writes publicly when he's under drugs), then it
becomes hard work.

Each issue needs an (estimated) average of 2 days mental attention
until it is solved in the language repository (where it benefits all).

Saying that this is no contribution at all is simply ungrateful and
insincere.

Here is RubyInstaller repository:
GitHub - oneclick/rubyinstaller: RubyInstaller for Windows - Build recipes

I don't have to prove my technical skills. The people that I'm
interested in, detect my abilities just from my writings - they don't
need to see a line of code.

But I'll reach code-level "naturally".

I'll most possibly try the DevKit when I reach C-level. I'll report as
usual issues that I spot and most possibly I'll send some code-level
changes via the usual channels.

So, the RubyInstaller doesn't actually install Ruby and its
dependencies? That's *all* that a setup package is required to do.
File association and path changing are very much optional, since Ruby
will work without those.

Ruby is operative without file associations to .rb/.rbw files. While
setting file associations is a sensible default for lots of software,
the usual use case of RubyInstaller is such that it is not clearly one
of the cases where file associations by default make sense; so the
safer choice is to minimize disruption by not setting them.
