Chrome Crawler – A web-crawler written in Javascript

EDIT: I now have a newer, better version of this called “Recursive

Depending on your level of geekness you may or may not enjoy this one.

I proudly present Chrome Crawler, my latest Google Chrome extension:

The idea is simple really. You just give it a URL, it then goes off and finds all the links on that page then follows them to more pages then gets all the links and follows them and so on and so on.

Along the way it checks each page to see if there are any ‘interesting’ files linked there, if it finds an interesting link it will flag it for you so you can check it out.

Theres an options page that lets you customise the way it all works:

If you are still confused check out the video below:

So why did I make this? Well to be frank, I made it mostly “just ’cause I can”!

Also having learned from my last Chrome Extension project PostToTumblr I realised the Chrome API allowed you to do some things that you wouldn’t normally be allowed to do on a website (nameley the Cross-Origin XHR) and I wanted to do something to take advantage of it.

It didnt take me long to knock out this project, one lazy Saturday for the majority of the code and today for a quick fix or two and to write this post and make the video. As such I expect there to be many bugs and problems so if you encounter one drop me an email (my address is found in the options page).

Oh finally, I wouldnt try using this on a google page as you will likely end up seeing this quite often:

Anyways you can grab it over on the Chrome extensions gallery here. If you enjoy it please leave me a review / comment, much love!

PostToTumblr v0.6

Just a quick update to my chrome extension tonight. I recently had an email asking if there was a way I could make it so that you could send a Tweet at the same time as posting to Tumblr.

After a quick check on the Tumblr API to confirm that yes Tumblr supports the “post-to-twitter” option I spun out this little option.

So now you have three options for tweeting when posting: “no”, “auto” and “prompt”.

Chrome should auto-update the extension for you soon. If you dont have it hope over to the gallery page here.

Multi-Line Flex Label [MXML]

Just stumbled across this one while writing some mxml for a personal project and thought I would share.

Have you ever wanted to have multi-line text in your label component in spark and thought the following should work?

[codesyntax lang=”mxml”]

<s:Label text="I like text on the n next line" />

[/codesyntax]

But all it produces is:

Yep me too.

After some playing however I stumbled accross the following solution:

[codesyntax lang=”mxml”]

<s:Label text="I like text on the {'n'} next line" />

[/codesyntax]

It then produces the expected result:

Im just guessing but I suspect its something to do with the black art of the flex life cycle. By adding the {‘n’} we are turning the property initialisation on the label component from a simple literal assignment into a delayed binding assignment and therefore gets parsed differently.

Just a guess, let me know if im way off.
