Welcome to the Wiki Tricks page. Here you can find how to reproduce some of the cool functionality you've seen on this wiki.
Please feel free to add your own wiki tricks as you discover them!

The Basics

Images

To put an image on a page, like: TmipClear.png, use the code:

[[Image:Example.jpg]]

after you have uploaded it. You can also specify that you want the image to be aligned right or left of text by writing:

[[Image:Example.jpg|right]] OR  [[Image:Example.jpg|left]]

and you can scale the image by giving it a pixel number, like this

[[Image:Example.jpg|350px]]

produces something like TmipClear.png

Links

In-wiki Links

For links to pages in this wiki such as "Newton's Basin", use the code:

[[Page Name| text you want shown]] OR [[Page Name]]

the latter code is used when the text you want shown is simply the page name. And, yes, when specifying the page name, cAsE MaTTerS.

Outside Links

For a link to an outside webpage, such as wikipedia, use the code:

[PageURL textYouWantShown] OR [PageURL]

the second will just show the URL as the link.

Some More Advanced Stuff

Splitting Text into Columns

Two Columns

  • To format text into two columns, do the following:
 <div style="float: left; width: 50%">
   Info for first column
   More info for first column
 </div><div style="float: left; width: 50%">
   Info for second column
   More info for second column
 </div>

Info for first column

More info for first column

Info for second column

More info for second column

Three Columns

  • And, to get text into three columns, use the following code:
 <div style="float: left; width: 33%">
    Info for first column
    More info for first column
 </div><div style="float: left; width: 33%">
    Info for second column
    More info for second column
 </div><div style="float: left; width: 33%">
    Info for third column
    More info for third column
 </div>
 

Info for first column

More info for first column

Info for second column

More info for second column

Info for third column

More info for third column

Mouse Overs

To generate a "balloon", use the code:

<balloon title="Text you want in balloon.">text for mouseover</balloon>


To generate a balloon with images, math, and links.

 <balloon title="load:Title of Content">text for mouseover</balloon>
  <span id="Title of Content" style="display:none">Text, links, math, images you want in balloon</span>

Hide/Show

Basic Hide/Show

To hide a block of text, for example:

Like this!

use the code:

{{hide|Text you want hidden}}

if your text contains an "=" sign, you must use the code:

{{hide|1=Text you want hidden}}

otherwise it appears as {{1}} in your page, which is silly.

"Hide This"

The HideThis option allows you to specify what it is you want to hide. For example,

{{HideThis|1=<text to follow hide/show>|2=<text to hide>}}

Switch

If you have two sets of text that you'd like to switch between--for example, one that's just images and one that's the images and the text that goes with them, you can do this by using the Switch function. The code for this is:

{{Switch|Click to expand|Click to hide|The text shown by default. |The text that you want to show when you click the first link!}}

which produces:

The text shown by default

The text that you want to show when you click the first link!


Align Your Equal Signs

If you have several equations that you want to fit on multiple lines with the equals sign lined up in a column, you can use the template "AlignEquals":

Example:

<template>AlignEquals |e1l=3/2 |e1r=1.5 |e2l=2/3 |e2r=0.3333... |e3l=13/8 |e3r=1.625 </template>

To do this, you should use the code:

 <template>AlignEquals
 |e1l=3/2
 |e1r=1.5
 |e2l=2/3
 |e2r=0.3333...
 |e3l=13/8
 |e3r=1.625
 </template>
 

where you fill in e1l with the content of the left side of your first equation, e1r with the content on the right side of your first equation, etc. Currently, the template handles up to 10 equations.

Numbering Equations

We can number equations using either a two-part code or a three-part code.

Two-part code

When using the two-part code, use :

{{EquationRef2|label or equation number}}

For instance, when you can use the code :

{{EquationRef2|Eq. 1}}  x^2+y^2=z^2

and it will appear as :

Eq. 1        x^2+y^2=z^2

When later referring back to the numbered equation, use the code :

{{EquationNote|label or equation number}}

An important thing to remember is that the 'label or equation number' part should be exactly the same for EquationRef and EquationNote. For instance, we can write

{{EquationNote|Eq. 1}}

and clicking on Eq. 1 will refer us back to the original equation.

Three-part code

When using a three-part code, use:

{{EquationRef2|label that you will remember|label that will appear on the page}}

For instance, you can label a equation as pythagorean theorem but make it appear as Eq. 2 by using :

{{EquationRef2|Pythagorean Theorem|Eq. 2}}x^2+y^2=z^2

and it will appear as :

Eq. 2         x^2+y^2=z^2.

When later referring back, as long as you make the 2nd part of the "EquationRef2" the exact same, you can change the 3rd part, and you will still be able to refer back to the equation. For instance, you can use :

{{EquationNote|Pythagorean Theorem|Equation 2}}

and Equation 2 will refer you back to the original equation.

Pausing GIF Animations

To enable pausing of gif animations, use the code:

<pausegif id="1" wiki="no">Hypotroc2.gif</pausegif>

where id can be anything, as long as multiple paused gifs on the same page DO NOT have the same name.

Click to stop animation.


Embedding Videos, Applets, Etc.

Embedding Videos

You can embed youtube videos by using the code

{{#ev:youtube|xI2eEcqz46E}}

where the xI2eEcqz46E represents the id assigned by youtube (you can find it in the URL of your video (e.g. www.youtube.com/watch?v=xI2eEcqz46E).

...and you can embed parts of youtube videos by using the code:

{{#ev:tubechop|xI2eEcqz46E&start=10&end=20}}

where start and end are the value (in seconds) of where in you want the clip to start and end.


Embedding Flash Movies

To embed flash movies (.swf files) on a page, first upload your file, then use the code:

<flash>file=filename.swf|attribute=value|...</flash>

"attributes" include width,height,scale,id. For example:

flash>file=cool.swf|width=200|height=300|bgcolor=#FDE742|scale=exactfit</flash></wiki>

For more information, visit the extension documentation here.


Embedding Java Applets

To embed Java Applets on a page, first upload your file(s) and then use the code:

<java_applet code="Example.class"  height="150" width="150" archive="Example.jar" />

For more information, visit the extension documentation here.

Note: For more advanced Java applets, specifically ones that use JavaView, contact a site moderator for help on embedding it on this site.

For Image Pages


Showing the "More Mathematical Explanation"

Here at The Math Images Project, we want our pages to be accessible to as many people as possible. That's why we, by default, hide the 'More Mathematical Explanation' on all of our image pages. However, if you would like to show the section, there is a way around this.

Note: We strongly encourage you to only use this option when the majority of the text in the section is hidden. We don't want to turn people away with scary math!

To do this, add the line |HideMME = No to your page within the Image Description template.
