[JavaScript] Tarpipe to twitter, jaiku and pownce

2008-05-31T00:52:35-07:00

<a href="http://tarpipe.com" >Tarpipe</a> is a service similar to yahoo pipes. It allows to send REST-wise posts to twitter, jaiku and pownce in one shot ;) Here's a short bookmarklet that should help you get productive on those micro-blogging platforms. Please teach me how to write better javascript. Thanks.

javascript:
popw=window.open('','Tarpipe micro-post','width=800,height=150');
popw.focus();
popd=popw.document;

popd.write('<form action="http://rest.receptor.tarpipe.net:8000/?key=PUTYOURKEYHERE" method="POST" enctype="multipart/form-data">');
popd.write('<p><input type="text" size="90" name="title" value=%s '+location.href/></p>');
popd.write('<p><input type="submit" name="Submit" value="pipe"/></p>');
popd.write('</form>');

[JavaScript] Zoom all image files from small to medium, medium to large etc..

2008-02-27T23:49:55-08:00

This one comes straight from Phillipe Lenssen's blog (http://blogoscoped.com/archive/2008-02-26-n57.html) where he shares with us this javascript bookmarklet hack to be used within friendfeed or any other web-page that uses "small" "medium" "large" parameter to encode their images...
You may need to tweak with the width and height; and with the "medium" to "large" parameters...

javascript:(function(){
    var elm = document.getElementsByTagName("img");
    for (var i = 0; i < elm.length; i++) {
        var sOld = elm[i].getAttribute("src");
        var sNew = sOld.replace(/=medium/g, "=large");
        if (sOld != sNew) {
            elm[i].setAttribute("src", sNew);
            elm[i].setAttribute("style",
                    "width:75px; height:75px");
        }
    }
})()

[JavaScript] On Mathtex bookmarklet

2008-02-17T03:13:27-08:00

Ok, I've made this one a little bit more handy. I've added text areas with image url and embeddable html code for your webpage, wiki or blog.

javascript:

popw='';
str=prompt("Type your tex:","%s");

cols=50;
match=/<([^<>]*)>/g;
subs="&lt;$1&gt;";

if(str){

    popw=window.open(
        '',
        'latexbox',
        'width=440,height=250'
    );
    popw.focus();


    imglnk='http://www.forkosh.dreamhost.com/mathtex.cgi?'+escape(str);
    textimglnk='<textarea rows="1" cols="'+cols+'">'+imglnk.replace(match,subs)+'</textarea>';

    imgtag='<img src="'+imglnk+'" alt="'+str+'"></img>';

    divtag='<div style="text-align:center;width:100%" >'+imgtag+'</div>';
    textdivtag='<textarea rows="3" cols="'+cols+'">'+divtag.replace(match,subs)+'</textarea>';

    popd=popw.document;
    popd.write(imgtag+'</br>');
    popd.write('link: '+textimglnk+'</br>');
    popd.write('html: '+textdivtag+'</br>');

}

[JavaScript] Mathtex bookmarklet

2008-02-15T11:11:38-08:00

Join the lines and save it as a bookmark.

This one aims to help users to embed latex equations in their blogs and wikis by using Mathtex and a little javascript bookmarklet.

<a href="javascript:popw='';y=window;str=prompt(%22Type%20your%20tex:%22,%22%s%22);if(str)%7Bpopw=window.open('http://www.forkosh.dreamhost.com/mathtex.cgi?'+escape(str),'latexbox','width=300,height=200');popw.focus();if (!document.all) T = setTimeout('popw.focus()',50)%7Dvoid(0);" >mathtex box</a>

javascript:
popw='';
y=window;
str=prompt("Type your tex:","%s");
if(str){
    popw=window.open(
        'http://www.forkosh.dreamhost.com/mathtex.cgi?'+escape(str),
        'latexbox',
        'width=300,height=200'
    );
    popw.focus();
    if (!document.all) T = setTimeout('popw.focus()',50)
}
void(0);

[PHP] On MediaWiki extension template

2008-01-29T18:47:24-08:00

Hmmm, nice!
And about this variant that does the "feeling lucky" magic link? It creates a <goto> tag. Pretty neat, huh? ;)
Sure saves me a-lot-of-time when posting articles in mediawiki or in wordpress...

BTW, remember to append 'include("extensions/goto.php");' to the LocalSettings.php file in your mediawiki directory.

<?php
# goto
# 
# Tag :
#   <goto>search string</goto>
# 
# Enjoy !

$wgExtensionFunctions[] = 'wfgoto';
$wgExtensionCredits['parserhook'][] = array(
        'name' => 'goto',
        'description' => 'Google "Feeling Lucky" linking',
        'author' => 'Guillaume Riflet',
        'url' => 'http://meta.wikimedia.org/wiki/goto'
);

function wfgoto() {
        global $wgParser;
        $wgParser->setHook('goto', 'rendergoto');
}

# The callback function for converting the input text to HTML output
function rendergoto($input) {      
        $output='<a href="http://www.google.com/search?hl=en&q='.$input.'&btnI=kudos" >'.$input.'</a>';
        return $output;
}
?>

[PHP] MediaWiki extension template

2008-01-29T18:42:20-08:00

Here's a nice little template for MediaWiki that allows to embed generic html using the <htm> tag :)

<?php
# html
# 
# Tag :
#   <htm>html code</htm>
# 
# Enjoy !

$wgExtensionFunctions[] = 'wfhtml';
$wgExtensionCredits['parserhook'][] = array(
        'name' => 'html',
        'description' => 'Display html',
        'author' => 'Guillaume Riflet',
        'url' => 'http://meta.wikimedia.org/wiki/html'
);

function wfhtml() {
        global $wgParser;
        $wgParser->setHook('htm', 'renderhtml');
}

# The callback function for converting the input text to HTML output
function renderhtml($input) {      
        $output=$input;
        return $output;
}
?>

[Perl] On Perl one-liner to extract xml tags values

2007-11-20T18:00:34-08:00

Tested. Works. I also added a sed command to remove blank lines. Anyone cares to insert that in the perl one-liner, for sports?

curl http://www.cnn.com | perl -ne 'm/>([^<>]*?)<\// && print$1."\n"' | sed -e '/^$/d'

[Perl] Perl one-liner to extract xml tags values

2007-11-13T17:19:53-08:00

Hello,
I'm a web-scrapping enthusiast and I script short one-liners in bash using sed, awk, perl, grep, tail, head, tr,... that sort of programs. Here's a really cool perl one-liner that basically extracts values from any xml(html) tag. You should try it. Can you make it shorter, or any more powerful?
Cheers,
Guillaume

[Python] Classtemplate

I'm new to python (and to OO programming in general). But I really enjoyed discovering the pydoc and the unittesting, doctest, concepts. Here's a first draft of a python primer ... Can you improve it?
