(Other) How to configure the output format of the W3 CSS Validator

Wed, 16 Sep 2009 11:53:08 GMT

The W3 CSS validator is pretty simple to [install locally for use behind the firewall](http://www.emacswiki.org/emacs/FlymakeCSS). However, by default the validator spits out the whole CSS file after validation, which is inconvenient if your stylesheet is more than a few lines long. Unfortunately it's not so obvious how to configure the validator to give pretty-printed, human-readable output. In fact, all there is to it, is to choose a different output format from the several that are supported :) By default the validator .jar file gives you "text" output, which includes the stylesheet. To choose a different format, invoke the validator .jar file with an -output argument, like this: java -jar css-validator.jar -output local-file:foo.css where `` is any of xhtml, xml, text, soap12, json, ucn or gnu If you just want the errors as (html-escaped) plain text, but without the CSS included, use `gnu`

(Ruby) Waiting for events with the Selenium-Client Ruby driver

Wed, 01 Jul 2009 10:57:06 GMT

## List of commonly used `wait_for` commands For convenience, here are direct links to the documentation of the Selenium-Ruby `wait_for` commands that are most often used. The [documentation of WaitFor commands in Selenium Core](http://release.seleniumhq.org/selenium-core/1.0.1/reference.html#waitForCondition "WaitForCondition entry in the docs for Selenium Core 1.0.1") may also be of interest. 0. [`wait_for_condition`](http://selenium-client.rubyforge.org/classes/Selenium/Client/Idiomatic.html#M000088) 0. [`wait_for_element`](http://selenium-client.rubyforge.org/classes/Selenium/Client/Extensions.html#M000257) 0.

[`wait_for_text `](http://selenium-client.rubyforge.org/classes/Selenium/Client/Extensions.html#M000259) ## Where to find the documentation More information on`wait_for` with the Ruby client, including a complete list of the `wait_for` commands available in the Ruby client, is to be found in the [documentation for the Selenium-Client Ruby Gem.](http://selenium-client.rubyforge.org/ "selenium-client is the official Ruby driver for Selenium RC") As Selenium-Client defines many "idiomatic" Ruby aliases for built-in Selenium methods, it will probably be especially helpful to become familiar with the [Selenium Ruby driver command set](http://selenium-client.rubyforge.org/classes/Selenium/Client/GeneratedDriver.html) as well as Selenium-Client's [Idiomatic Ruby command set.](http://selenium-client.rubyforge.org/classes/Selenium/Client/Idiomatic.html) It may also be helpful to refer to the [documentation for Selenium Core](http://release.seleniumhq.org/selenium-core/1.0.1/reference.html#waitForCondition "WaitForCondition entry in the docs for Selenium Core 1.0.1") with regard to `WaitForCondition` and related commands. In general the **Selenium Core documentation** tends to provide more insight into how commands work, than does the documentation for any of the drivers. ## Examples Below are a couple of examples of using Selenium's `wait_for` family of commands with the [Ruby driver (Selenium-Client).](http://rubyforge.org/projects/selenium-client/ "Selenium Client Ruby Gem at RubyForge") One item of note is that , within `wait_for_condition`, one does *not* need to use `this.browserbot.getCurrentWindow()` to access the DOM of the AUT

(Perl) Fuzzy string matching with Perl

Sat, 27 Jun 2009 01:09:08 GMT

Fuzzy string matches with Jarkko Hietaniemi's String::Approx module. **Get approximate matches, close to what you want.** This is great for when you have filenames that might contain misspellings, extra underscores or other typos and mistakes. Also great for searching for files when there are several different naming conventions used within a project. Mainly I am concerned with being able to match strings that have underscores inserted (or deleted) in arbitrary places. But the result I came up with here, does a pretty good job of matching when there are all sorts of typos, without picking up *too* many false positives.

(Perl) Automated UI test with Selenium-RC, WWW::Selenium and Test::More

Sat, 15 Sep 2007 10:49:16 GMT

In order for this to work, the Selenium-RC server must be running. See also the tutorial at http://search.cpan.org/~mschwern/Test-Simple-0.71/lib/Test/Tutorial.pod

(JavaScript) Does an object have a specific property?

Thu, 24 May 2007 09:24:08 GMT

This is a very easy way to check if an object has a given property. Easier than checking if (obj.foo != null) or some such, which is what I've been doing :( From Flanagan, 5th ed, p. 108.; but I actually ran across it in the source of this page: http://www.gtalbot.org/DHTMLSection/DynamicOpacity.html, thanks to Gerard Talbot on clj.

(JavaScript) Does an element exist?

Fri, 04 May 2007 08:10:36 GMT

Does an element exist in the current DOM tree? Because I can never remember whether I should test typeof el == null... or el == null
