Ruby Code to HTML

[James Edward Gray II]

I need to HTMLify some Ruby code. Before I go make some crude
solution, I thought I would ask if there is anything out there along
these lines. Any pointers?

Thanks.

I seem to remember a tool like that. Would be in RAA if so.

Also, I think vim can do that.

Depends. What are you trying to accomplish? I have something that
takes ruby with special comments and makes a cross reference
(hyperlinked) between it and a specification document. But it doesn't
really "read" the ruby code, or format it--it just spits it out <CODE>
with <A>'s interpolated based on the comments.

I briefly thought about linking methods calls to their definitions,
etc., but with duck typing that is...almost intractable. The best I
came up with was a sort of method search that sort of worked, but didn't
find dynamically defined methods, etc.

Vim. If you use Vim, you can do

:runtime! syntax/2html.vim

It'll create a new window with your Vim file converted to HTML.

A quick and dirty way might be:

#!/usr/bin/ruby

input = File.open( "file.rb" , "r" )
output = File.new( "file.html" , "w+" )

input.each_byte{ |c|
case c.chr!
when "\n"
output.write( "<br>\n" )
when "\s"
output.write( "&nbsp;" )
when "\t"
output.write( 4.times{ "nbsp;" } )
else
output.write( c )
end }

There's an Emacs package called htmlize. If you want to htmlize every
Ruby file in a certain directory, open the directory with C-x d, hit %
m, give it a regular expression like .rb$, and do M-x
htmlize-many-files-dired. It will write one .html file for every .rb
file.

Here's htmlize: http://fly.srk.fer.hr/~hniksic/emacs/htmlize.el

RubyForge's ViewCVS setup uses enscript to do markup. Here's an
example:

The enscript colorizer file is here:

There's a utility called rb2html that works well.

A better version might be:
--------------------------------------------------------------

input = File.open("baselayout_test.rb")
output = File.new( "baselayout_test.html" , "w+" )

input.each_byte{ |c|
c=c.chr
c.gsub!(/\n/ , "<br>\n" ) and output.write( c ) and next if( c=~/\n/ )
c.gsub!(/\s/ , "&nbsp;" ) and output.write( c ) and next if( c=~/\s/ )
c.gsub!(/\t/ , "&nbsp;&nbsp;&nbsp;&nbsp;" ) and output.write( c )
and next if( c=~/\t/ )
output.write( c ) }

Sorry if I wasn't clear. I do want to identify elements of Ruby syntax.

Thanks for all the posted solutions. I'm looking through them to see
if I can find what I need...

A quick and dirty way might be:

Oh well if that's allowed, then how about:

File.open("file.rb") do |r|
File.open("file.html","w") do |w|
w.puts "<pre>"
r.each_line do |line|
line.gsub!(/&/,'&amp;')
line.gsub!(/</,'&lt;')
line.gsub!(/>/,'&gt;')
w.puts line
end
w.puts "</pre>"
end
end

Exactly. I've written a Ruby script that uses vim to transform source
codes easily to colorized html.

If you need to parse Ruby code and access to elements of Ruby syntax,
take a look at the CVS HEAD version of Ruby 1.9. It comes with the
ripper library integrated.

Cheers,
Kent.

I'm currently using xemacs to htmlify code (example code for my slides),
but if you find a html-izer that does real parsing, please share your find.

Thank you,

Brian

The ruby2html link posted earlier in this thread seemed to be a real
parser. I want through it's source code, looking around. It didn't
have any English documentation though, unfortunately.

You might want to look at:
http://phrogz.net/JS/Classes/syntaxcolor.js

It's a little script I wrote which automagically syntax colors
javascript code inside of <code class="js"> blocks, and shouldn't be
*TOO* hard to extend to give at least basic ruby syntax coloring. (It's
all regexp based, so complex things like properly coming in/out of %Q{
or %Qn won't work well. But at least it's a start.)

Man, with more time in my life, I'd love to write a general-purpose JS
syntax-coloring state machine

 

[Gavin Kistner]

You might want to look at:
http://phrogz.net/JS/Classes/syntaxcolor.js

Erps, I meant:
http://phrogz.net/JS/Classes/syntaxcolor_test.html

seen in action there, and in various files in that directory, like:
http://phrogz.net/JS/Classes/ExtendingJavaScriptObjectsAndClasses.html

(note the pretty colors sprinkled throughout, yet the source file is
clean and easy to read/change)

Hi!


The scite editor, which comes with the ruby one click installer, has an
export to html feature.

Works okay for me.
