Clearly if you want to develop a real web application, you need a router, a templating language, ability to separate out your model, view, and controller, scalability, and much more. However, at times this is both too much, and yet not enough. I find that I write a lot of scripts that do report generation, execution of shell commands, and the like, and in many cases would like to present a richer output than plain text: things like tables, fonts, and most importantly hypertext links. I don’t want to worry too much about DOCTYPEs, charsets, and escaping, but instead on structure, style, and content. I’ve been extracting some of the common logic from these scripts out into a library, and recently have started refactoring that library. Yesterday, I focused on the HTML generation parts. What I settled on was to define all methods that start with a low line character will generate a HTML tag. As with builder on which this library is based, these tags can have text content and attributes. Tags can also be nested. Logic can be freely intermixed. Here’s an example using the library. The example will personally greet you if you provide your name. If no name is provided, a form is provided which enables you to provide one. #!/usr/bin/ruby1.9.1
require 'wunderbar'
Wunderbar.html do
_head do
_title 'Greeter'
_style %{
input {display: block; margin: 2em}
}
end
_body? do
if $param.name
_p "Hello #{$param.name}!"
else
_form method: 'post' do
_p 'Please enter your name:'
_input name: 'name'
_input type: 'submit'
end
end
end
end
Here’s example output from that script: <!DOCTYPE html>
Greeter
input {display: block; margin: 2em}
As you can see, by default it takes care of indenting and generation of HTML. It even knows which tags support explicit close tags and which ones do not. Not shown in this example, but these default behaviors can be overridden by adding an exclamation mark at the end of the method name. An example would be something like: _p! { _ "Hello "; _span $param.name, class: 'name'; _ '!' }
An underbar which is not followed by a name generates text. Example output: Hello Sam!
The span can be styled using css. If your web server is set up to execute CGI scripts, deployment is as easy as copying the script into the appropriate directory. Port Forwarding

Published on : 2011-11-24 07:22:10 The git vs svn permathread seems to have reignited at the ASF, and I thought I would describe some of my actual experiences with git in the hopes that it will help anchor the discussion. The context: I’m co-author of a book on Rails. I have a vested interest in the scenarios described in that book continuing to work, so I wrote a few tests that I run against various combinations of Book editions, Rails releases, and Ruby versions. From time to time, a test fails. One of the first things I typically do is run git bisect. All I need to do is to identify a good version, a bad version, and a test to run. Even if the test takes 2 minutes and there are 30 or so revisions between the good and bad points, I get an answer in about 10 minutes without needing to be further involved in determining where the problem is. I mention it to a developer, and the first thing he does is place a comment on the the actual commit. The next thing I do is build a smaller test case. I have a scenario that fails. I know a revision that it passes on. I whittle down the scenario to one that continue to fail with the same symptoms and passes on the known good revision. I post a comment on the same commit. At this point, I have a small test and a commit that fails. I may not know the full Rails codebase, but the commit page shows what changed and I can make an educated guess as to what the problem is. I post my patch for all to see. I request that this patch be pulled. Within minutes it is, and the pull request is closed. Can all of this be done using svn and JIRA? Absolutely. I’ve used Are any of these features absolutely necessary? Well, no. I’m even aware that pieces are available like svn-bisect. But I can see how people that have gotten used to having everything integrated and at their fingertips feel like they are taking a step huge backwards when they migrate to an environment that doesn’t.
