Word Wrapping IE's Plain Text

If you view a plain text document in Internet Explorer 8, for instance the plain text version of Cory Doctorow's book Little Brother and press F12 to bring up the developer toolbar, you can see that IE simply takes the plain text, sticks it inside a

 tag, and renders it.  This means that word wrapping isn't supplied and the only line breaks that appear are those in the document.  However, since the text document is converted to HTML it means I can implement word wrap myself using a bookmarklet:
javascript:function ww() { var preTag = document.getElementsByTagName('pre')[0]; preTag.style.fontFamily="arial"; preTag.style.wordWrap='break-word'; }; ww();
After adding a favorite and setting the favorite's URL to the previous, I can view plain text documents, and select my Word Wrap favorite to apply word wrap and non-fixed width font.

Investigation of a Few Application Protocols (Updated)

Windows allows for application protocols in which, through the registry, you specify a URL scheme and a command line to have that URL passed to your application. Its an easy way to hook a webbrowser up to your application. Anyone can read the doc above and then walk through the registry and pick out the application protocols but just from that info you can't tell what the application expects these URLs to look like. I did a bit of research on some of the application protocols I've seen which is listed below. Good places to look for information on URI schemes: Wikipedia URI scheme, and ESW Wiki UriSchemes.

QuickBase Formula Pretty Printer and Syntax Highlighter

Sarah asked me if I knew of a syntax highlighter for the QuickBase formula language which she uses at work. I couldn't find one but thought it might be fun to make a QuickBase Formula syntax highlighter based on the QuickBase help's description of the formula syntax. Thankfully the language is relatively simple since my skills with ANTLR, the parser generator, are rusty now and I've only used it previously for personal projects (like Javaish, the ridiculous Java based shell idea I had).

With the help of some great ANTLR examples and an ANTLR cheat sheet I was able to come up with the grammar that parses the QuickBase Formula syntax and prints out the same formula marked up with HTML SPAN tags and various CSS classes. ANTLR produces the parser in Java which I wrapped up in an applet, put in a jar, and embedded in an HTML page. The script in that page runs user input through the applet's parser and sticks the output at the bottom of the page with appropriate CSS rules to highlight and print the formula in a pretty fashion.

What I learned:

• I didn't realize that Java applets are easy to use via script in an HTML page. In the JavaScript I can simply refer to publicly exposed methods on the applet and run JavaScript strings through them. It makes for a great combination: do the heavy coding in Java and do the UI in HTML. I may end up doing this again in the future.
• I love ANTLRWorks, the ANTLR IDE, that didn't exist the last time I used ANTLR. It tells you about issues with your grammar as you create it, lets you easily debug the grammar running it forwards and backwards, display parse trees, and other useful things.

Anecdotes from Work

The names in the following anecdote have been changed. Except for my name (I'm Dave).

I got a new laptop a while back. I had it in my office and Tim came in to ask me something but paused when he saw my laptop. "Oh, is this one of those new touch screen laptops?" he asked, the whole time moving his hand towards my laptop and punctuating his sentence by pressing his finger to the screen. "No" I responded.

Walking down a hallway I heard Winston, one of our managers, say, "Hey Tim!" Winston catches up to me and asks, "Are you almost done with the XYZ bug?" I realized Winston was talking to me and got my name wrong but I figured I'll ignore it and perhaps he'll realize his mistake. Winston continued "I just talked with some people who say they're blocked and waiting for Tim to finish the XYZ bug." "Dave" I said helpfully attempting to diplomatically correct Winston since he apparently hadn't realized his error. "No, it was Jeremy and Bill." Winston said naming the people he had talked to who were waiting for me to fix the XYZ bug. At this point I decided it would be easier to just answer his question and end the conversation than to get into this whole thing. As far as I know, Winston has not gotten my name wrong at any other time.

Party Movies Recommended by Netflix

Netflix has recommended three party movies over my time with Netflix and if you're OK with movies featuring sex, drugs, rock&roll (or techno) as almost the main character then I can recommend at least The Boys and Girls Guide to Getting Down.

24 Hour Party People is based on the true story of Tony Wilson, journalist, band manager, and club owner (not all at once) around the rise of punk and new wave in England. Like many true-story based movies it starts off strong and very interesting but gets very slow at the end like the writers got bored and just started copying the actual events. Unless you have some interest in the history of music in the 80s in Manchester I don't recommend this movie.

Human Traffic is fun and funny following a group of friends going out for a night of clubbing and partying. I had to get over seeing John Simm as not The Master from Doctor Who but rather as a partying youth. It felt like it was geared towards viewers who were on something like the totally odd techno musical interludes with the characters dancing for no apparent reason. Otherwise the movie was good.

The Boys and Girls Guide to Getting Down is done in the style of an old educational movie on the topic of clubbing and partying. It sounds like a premise that would get old but they do a good job. While demonstrating drinking and driving they have scientists push a mouse around in a toy convertible. Enough said. It was funny and I recommend it.
