Off to Germany

2008 Nov 28, 1:27

Sarah and I are off to Munich tomorrow. I was about to lose a lot of vacation time if I didn't use it so its good timing and it will be nice to get away from work for a bit. I've made a map of some of the places I'd like to visit. Prost!

Clips: The Kids In The Hall Think Portal Is HILARIOUS

2008 Nov 20, 11:30KITH + Portal! "We're not sure how deep into the goof juice the Kids in the Hall were when troupe funnyman Scott Thompson started sulking and playing Portal in the back of the tour bus, but something got into Kids during this sad little gaming session. Yes, the comedic stylings of Valve writer Erik Wolpaw are most amusing, as is the struggle of watching Thompson attempt to do anything more than move a cube - uncrouch already! - but something tells me there's something magical in those cups.

Text/Plain Fragment Bookmarklet

2008 Nov 19, 12:58

The text/plain fragment documented in RFC 5147 and described on Erik Wilde's blog struck my interest and, like the XML fragment, I wanted to see if I could implement this in IE. In this case there's no XSLT for me to edit so, like my plain/text word wrap bookmarklet I've implemented it as a bookmarklet. This is only a partial implementation as it doesn't implement the integrity checks.

Check out my text/plain fragment bookmarklet.

Tab Expansion in PowerShell

2008 Nov 18, 6:38

PowerShell gives us a real CLI for Windows based around .Net stuff. I don't like the creation of a new shell language but I suppose it makes sense given that they want something C# like but not C# exactly since that's much to verbose and strict for a CLI. One of the functions you can override is the TabExpansion function which is used when you tab complete commands. I really like this and so I've added on to the standard implementation to support replacing a variable name with its value, tab completion of available commands, previous command history, and drive names (there not restricted to just one letter in PS).

Learning the new language was a bit of a chore but MSDN helped. A couple of things to note, a statement that has a return value that you don't do anything with is implicitly the return value for the current function. That's why there's no explicit return's in my TabExpansion function. Also, if you're TabExpansion function fails or returns nothing then the builtin TabExpansion function runs which does just filenames. This is why you can see that the standard TabExpansion function doesn't handle normal filenames: it does extra stuff (like method and property completion on variables that represent .Net objects) but if there's no fancy extra stuff to be done it lets the builtin one take a crack.

Here's my TabExpansion function. Probably has bugs, so watch out!

function EscapePath([string] $path, [string] $original)
{
    if ($path.Contains(' ') -and !$original.Contains(' '))
    {
        '"'   $path   '"';
    }
    else
    {
        $path;
    }
}

function PathRelativeTo($pathDest, $pathCurrent)
{
    if ($pathDest.PSParentPath.ToString().EndsWith($pathCurrent.Path))
    {
        '.\'   $pathDest.name;
    }
    else
    {
        $pathDest.FullName;
    }
}

#  This is the default function to use for tab expansion. It handles simple
# member expansion on variables, variable name expansion and parameter completion
# on commands. It doesn't understand strings so strings containing ; | ( or { may
# cause expansion to fail.

function TabExpansion($line, $lastWord)
{
    switch -regex ($lastWord)
    {
         # Handle property and method expansion...
