Comment on PowerShell and MongoDB by Doug

Doug — Wed, 11 Aug 2010 23:54:29 +0000

Thanks for posting it Mike. I may have a small MongoDB project and this will shortcut my work.

You’ve made us collectively smarter.

One of the ideas I like about using MongoDB/RavenDB is I can get going quickly without defining schemas up front.

Thanks again for the post.

Comment on The Identity Function by mike

When I first tried to recreate this (I dimly remembered seeing it somewhere, and I really wanted to avoid quoting all the items in a large list), I tried something like your suggestion.

Unfortunately, by specifying an argument ($x), you’ve lost all of the magic. This will bind $x to the first item in the list, and the rest get bound to $args. If you pass “a b c” as to your scriptblock, you only get “a” back. The usefulness in this comes from getting the list of arguments back as an array.

Thanks for the comment.

Comment on The Identity Function by Doug

That is cool. Didn’t know that was the identity function. I came across this from Bruce Payette and Jeffrery Snover and use it like this all the time:

function ql {$args}

$list = ql tom dick harry

Also, isn’t this also the identity function in PowerShell?

{param($x) $x}

Then you can apply the identity function to the identity function:

& {param($x) $x} {param($x) $x}

Good stuff

Comment on The PowerShell Bug That Wasn’t, and More Package Management by Fred

What you get is an error from your sample code, because you can’t dot-source a function in bash (I just tried it), but only a file.

I can’t think of a cognate way to test this in bash; it has been a very long time since I did any bash scripting.

I hadn’t thought about other shells…I don’t really know much about bash (other than “learn bash in 24 minutes” kind of stuff). I wonder if it has the kind of scoping that PowerShell does and how that plays out with its version of dot-sourcing.

I’m not sure if the behavior is the same in them, but bash (and probably other unix scripting languages) use dot sourcing.
