Having Ruby start a browser with the correct form.html file is easy enough.
I suspect the tricky part for you is after the user hits the ‘Submit’
button. That is usually tied to an Action that is typically another web
page. At this point, an HTTP server is required (thus the Apache
recommendation). That’s because when the browser goes to find the Action
web page, it expects to be able to communicate to a Web server that is
listening on a particular port for web requests. Communication through this
port to the web server is how the parameters from the form will get passed
to the Action page.
I suppose you could write a Ruby program that would listen on a particular
port (7829 spells Ruby on the phone keypad!) and maybe could handle it the
communication. Is that what you’re thinking of? But in this case you’re
repeating the communication code that is already written in Apache.

Subject: Re: How do I handle an HTML form from ruby?
OK, first thank you for your help.
Now, let me make an attempt to explain what I want to
do.
On my quest to learn ruby, I wanted to design a simple
address book application. I wanted to be able to
display some kind of window/form with entry fields for
the mundane items that goes on a phone/address book.
First I thought about using a GUI interfact Tk/Fox.
Then I thought about using something simpler and more
“standard” to collect the data. So after reading about ruby
sopporting html forms and since the majority of the systems
out there use some kind of browser, I thought that perhaps I
could use html ruby support. But it appears that although it
is easy to design the form, it is not that easy to display
it. I wanted to capture input data (phones, addresses,
etc.) and output the same type of data, after a
search.
No, I don’t have an HTTP server running. I guess I
could install apache, but I thought that it was
much
simpler.
All the examples make it look simple. Oh well!
Ludwigi, I’m not sure what you want exactly.
I am trying to learn how to manipulate HTML
files
with
ruby at the same time that I learn HTML. I
created
a
simple html file that contains among other
things,
input text fields and some buttons.
What do you mean by “manipulate”? Do you want to
treat an HTML file
as text and do some processing on it, for example
extracting the URL
of an image, or do you want to build a web
application that processes
the user input in some way?
The problem now is:
How do I tell ruby to run the html file?
What do you mean by “run” the file? If you only want
to look at it,
then you just …
Do I need to passit to a browser and if so,
how?
… open the file in your browser (usually via the
File/Open menu).
How do I capture user’s input?
This is where you start building a web application.
If you press the
submit button in the browser, the browser sends the
user’s input via
the HTTP protocol somewhere (the target being
mentioned in the
tag). So you need a program that is able to process
the data. I
suppose you want to use a Ruby program for that. If
so, then you have
several choices, for example Webrick (look in the
RAA).
I installed Eclipse and the ruby plug-in for it.
However, I don’t see anyway to use it and create
widgets.
Do anyone outthere have any sample code or any
instructions on how to use Eclipse and ruby together?
Thank you

At this point the Ruby Eclipse plugin only allows the
editing/running/debugging of Ruby code; unfortunately,
there is no ability
to script Eclipse itself using Ruby.

Now there’s a good idea. Elsewhere I suggested the ability to call
Perl modules from Ruby. It would be just as great to be able to call
Java from Ruby. Java has pretty good reflection, so it shouldn’t be too
hard to build dynamic wrappers for Java objects…

I think Mauricio Fernandez is working on a bridge beetween ruby and

even if it’s still alpha, seems really interesting to me

Well, since I am just a neophyte on the subject, I can
only speak for myself. I define “estable” an
environment that is available when I need it. Where I
work we have AIX, HP, Solaris, Linux. AIX is always
available.

Obviously it was a typographical error. But I was so
much into the meaning of the stmt that I did not see
through the sarcasm of others. Oh well, thats what
happens when you are naïve. However, I will be willing
to bet that most of the responder can ONLY speak one
and no more than one natural language, English. Those
are most of the time called North American.

It’s probably just the word “Stable”. I would guess
that Ludwigi
entered a typo.

I assumed it was a typofor “stable.”
<D’oh!> Of course. chuckle… thanks. =)

It does look like “nestable” with a missing n.
Actually after reading my own post, I thought it
would be funny if you said, “I don’t know the
word ‘typofor’ – what does that mean?”

I was not being sarcastic; I honestly didn’t see the “obvious” typo, or I would
not have asked.

Is this in any way relevant, or just an easy “slam” on North Americans? Some
equally unflattering (and likely equally untrue) generalities may be made about
Europeans.
