User Scripts Broken in Google Chrome?

December 11th, 2009

A little while ago my custom user script for Chrome stopped working. I’m currently using the “dev channel” at home. When I first switched to Chrome, that was the only version that supported user scripts (basically GreaseMonkey from FireFox integrated into Chrome).

My script is simple, it makes some font and color changes to a few websites that I view regularly to make them more legible (IMHO). I should bundle it into an extension some day…

Anyway, it took a bit of research to figure out what happened. Look here on the Google Chrome blog:

[r33013] Disable –enable-user-scripts. (Issue: 27520)
NOTE: You can now install user scripts by navigating to them. You will have to reinstall your current scripts (they aren’t migrated).

— http://googlechromereleases.blogspot.com/2009/12/dev-channel-has-been-updated-to-4.html

So, scripts are still supported, but I have to install it again. I didn’t quite understand “navigating to them” meant, but it actually means exactly what it says. In the address bar browse the file system, e.g. go to here:
C:\Users\%username%\AppData\Local\Google\Chrome\User Data\Default\User Scripts

Then double click on your .JS file, and a little extension installation prompt pops up. It’s pretty cool actually.

Hmm… now that Google Chrome regular version supports extensions, I might be able to take myself off the dev channel.

The Missing Menu Bar in Vista

November 11th, 2009

A few weeks back  I discovered the missing menu bar in Explorer in Vista.  All you have to do is press and release the Alt key and the good old “File | Edit | View | Tools | Help” menu pops up.  I find this useful to get to “Map Network Drive” no matter where I am in the computer browser.  Otherwise, the only link was the  context sensitive button that shows up at the “Computer” level.

Only a few more Vista annoyances to go!  OK,  it would have been smarter to post this before Windows 7 launched; however, Vista will be running on this laptop until it dies of old age.

Cross Browser Compatibility of TEXTAREA and Chrome, Firefox, and IE with CSS “white-space: nowrap;”

October 19th, 2009

Today, the Perceptus Web Tools got a minor upgrade to improve browser compatibility.

A company bought a  license to our unique Excel to SQL INSERT Commands tool for their internal, confidential, use.  Cool! We never expected tools.perceptus.ca to be a revenue generator… but it does have unique features.  After all, we wrote them because we couldn’t find another website that could do the task for us!

In the interest of delivering a nice package to our new licensee, we  noticed that many of the text mangling features did not work in Google  Chrome.  Chrome web browser was stripping line breaks and consolidating sequential “spaces”.  We then realized that the site was not working in Internet Explorer either. Whoops.  Well, it is a  site primarily for our own internal uses, after all.

We had discovered a browser compatibility issue that probably affects very few people. We want a textarea without any wrapping, because some features are based on copy and pasting large amounts of data from Excel – automatic text wrapping makes hard to read.

Our original, Firefox functional, Chrome and Internet Explorer non-functional, TEXTAREA used the following:

  • CSS: white-space: nowrap;
  • TEXTAREA attribute: WRAP=”OFF”

In Firefox, we got a nice blob of text that you can scroll horizontally displayed.  In IE7 and IE8?  All kinds of crazy.  “Enter” keys got replaced by some sort of special inline character, lines and spaces got trimmed or cut out.  Google Chrome stripped out line breaks and leading spaces, and other oddities.

Upon research, we learned that the “WRAP” attribute is not W3C approved.  Technically, it is not deprecated, but that’s because it never existed in the specifications. So we removed it and tried to use only CSS. We tried a few combinations of the overflow, white-space, and display CSS properties.  They didn’t work.

What did work?

No CSS at all.

If you view the source of the tools.perceptus.ca site and the corresponding CSS file, you will only see this:

<TEXTAREA NAME=”thetextROWS=”20COLS=”100WRAP=”OFF“>

This works as we wanted in all three web browsers.  It is officially non-standard.  But it works.

If someone would like to submit a CSS that will actually work, I’d love to see it.  But for now, I’m just going to keep complaining about how much web programming still stinks. Maybe the moral of the story is that thanks to Apple’s Safari and Google Chrome, every web site should be tested against at least one of the Webkit based browsers in addition to Firefox and Internet Explorer.
