Hello,   I've uploaded version 0.1 of slideshow - a Ruby gem that lets you create slide shows and author slides in plain text using a wiki-style markup language that's easy-to-write and easy-to-read.   Slide show delivers an all-in-one-page handout and a live full screen slide show with thumbnails all at once from a plain standard web page and much more. Comments and questions welcome.    Find out more @ [http://slideshow.rubyforge.org](http://slideshow.rubyforge.org)    Cheers. > **···** > > -- > Gerald Bauer - [http://rubybook.wordpress.com](http://rubybook.wordpress.com) ---

Hi, In the home page its claimed that we can have different theme. However I could not find anywhere how? Another question is that can we have powerpoint templates exported and use in slideshow as theme?

There's no CSS acrobatics involved either and the HTML that gets generated is not just a slideshow but also an all-in-one handout. Also note that to author your slides there's actually no HTML needed because you author your slides in "standard" textile - in plain text using a wiki-style markup language that's easy-to-write and easy-to-read.    Cheers. > **···** > > -- > Gerald Bauer - [http://rubybook.wordpress.com](http://rubybook.wordpress.com) ---

Hi, One more query. Can I create images, one for each slide?

Stupid new user question. I'm running ruby 1.8 on Linux, and I've installed gems, and I've done 'gem install slideshow ', and 'gem query --local' indicates that slideshow (0.2) is installed, but I can't find the executable. Where does gems install executables? > **···** > > -- > Collins Richey > If you fill your heart with regrets of yesterday and the worries > of tomorrow, you have no today to be thankful for. ---

I will post the updated v0.3 version in the next couple of days.    To answer your questions:    Try the command: gem env    It should tell you among other environment settings:   RUBY EXECUTABLE: c:/prg/ruby/v186/bin/ruby.exe    I'm running on Windows so your setting will differ. Gem executables get installed in the bin folder that holds the ruby executable.    Cheers. > **···** > > -- > Gerald Bauer - Internet Professional - [http://geraldbauer.wordpress.com](http://geraldbauer.wordpress.com) ---

ok, gen env points me to /usr/lib/ruby/gems/1.8/gems/slideshow-0.2/bin/slideshow Slideshow has a normal Linux shebang setup, ie #!/usr/bin/env ruby require 'rubygems' require 'slideshow' Slideshow.main If I mark the file executable and run it from the directory containing the sample, it doesn't work. Something about the gem setup must be wrong. > **···** > > On Sat, Mar 8, 2008 at 11:46 AM, Gerald Bauer \ wrote: > > > Hello, > > > > \> Stupid new user question. > > \> > > \> I'm running ruby 1.8 on Linux, and I've installed gems, and I've done > > \> 'gem install slideshow ', and 'gem query --local' indicates that > > \> slideshow (0.2) is installed, but I can't find the executable.

Note, your examples are for Windows, and not directly relavent for Linux. 1. The standard executable path on (most) Linux systems is '/usr/bin', and this is where ruby and irb reside. 2. 'gem query --local' shows the following \*\*\* LOCAL GEMS \*\*\* RedCloth (3.0.4) slideshow (0.2) 3. As expected, /usr/bin/redcloth exists, and it looks like the sample you quoted. 4. There is no /usr/bin/slideshow Either your gem is defective or gem itself is defective. I'll try building the executable manually and see if it works. > **···** > > On Sat, Mar 8, 2008 at 10:19 PM, Gerald Bauer \ wrote: > > > Hello, > > > > \> ok, gen env points me to > > \> > > \> /usr/lib/ruby/gems/1.8/gems/slideshow-0.2/bin/slideshow > > \> > > \> Slideshow has a normal Linux shebang setup, ie > > \> > > \> #!/usr/bin/env ruby > > \> require 'rubygems' > > \> require 'slideshow' > > \> Slideshow.main > > \> > > \> If I mark the file executable and run it from the directory containing > > \> the sample, it doesn't work. > > \> > > \> Something about the gem setup must be wrong. > > > >    You're looking at the Ruby script not the shell script/exectuable > > generated by RubyGems.

Hello, > Note, your examples are for Windows, and not directly relavent for Linux.    I try it on a Linux box later this week to see what's different and I'll keep you posted. Thanks for your patience.    Note, I've updated the gem to version 0.3. I'll send out an announcement later this week once I've updated the website too. What's new (a teaser ;-)? You can now use Markdown as an alternative to Textile. See [http://slideshow.rubyforge.org/svn/samples/rest.text](http://slideshow.rubyforge.org/svn/samples/rest.text)     Again thanks for your trying the Slide Show (S9) gem.     Cheers. > **···** > > -- > Gerald Bauer - Internet Professional - [http://geraldbauer.wordpress.com](http://geraldbauer.wordpress.com)
