This script is for PERSONAL use only!
You are free to install this script for yourself, but it is not allowed to be used wiki-wide (e.g., in MediaWiki:Common.js or MediaWiki:Wikia.js), as it would violate FANDOM's Terms of Use.

High priority
This script is currently in Alpha testing. It is functional, but there may be known problems or some of the features may be incomplete. It should be safe to use but anything and everything about how it works and looks may change drastically at any time.

HideRail adds a button to the Oasis toolbar that can hide the Wikia Rail when clicked (the bar on the right with the Recent Activity / Recent Uploads / Ads / etc) and restore it when clicked again. The search box will remain visible after the rail is hidden so you won't lose any important functionality by hiding it.

By default, Oasis squeezes articles into a rather narrow 670px column, you can use this tool to get the full 1010px width instead. This reduces the amount of scrolling needed to read a whole article.

Beyond article pages, the script also provides functionality for improving Edit pages by hiding the Editor Rail in Visual mode, not just Source mode. It also includes OasisWideMode built-in, which lets you enable the 1200px Oasis skin on any wiki.

importArticles — Best Practices for installing JavaScript on FANDOM
The importArticles statement is designed to combine multiple HTTP requests into a single data transfer, allowing multiple scripts to load and execute faster. If you've been installing several different scripts, your JavaScript file has probably accumulated unnecessary import statements. Click "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner. One other approach is by using the MediaWiki:ImportJS.
If your JavaScript file has several lines of code that say importScript, importScriptPage, or importArticles, you may be able to combine them! By batch importing a collection of scripts with a single import, your JavaScript code will load faster and look cleaner. Consider the example below. On the left is an example of what your JavaScript file might currently look like. On the right is how you could improve that code.
Multiple imports — messy and slow One import — clean and efficient

Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
But there's much more to importArticles than just this! For more examples and advanced usage, see the help page at Help:Including additional JavaScript and CSS.


You can customise the appearance of the button using your Wikia.css or global.css:

/* Disable the default arrow images */
a.hiderail-link-expand, a.hiderail-link-shrink {
    padding-left: 0;
    padding-right: 0;
    background-image: none;
/*** Example 1 ***/
/* Display text arrows instead */
.hiderail-link-expand:after {
    content: "  \2192";
.hiderail-link-shrink:before {
    content: "\2190  ";
/*** Example 2 ***/
/* Display custom icons on the left side always */
.hiderail-link-expand:before {
    content: url("http://whatever/my custom icon 1.png") ' ';
.hiderail-link-shrink:before {
    content: url("http://whatever/my custom icon 2.png") ' ';

The CSS classes are hiderail-link-shrink for the shrink button, hiderail-link-expand for the expand button and hiderail-link-generic for when the expand button is disabled (no rail).
