Global Javascript Plugin

Allows the user to create custom javascript for their WordPress powered site on a global level.

The Javascript made by the user of the plugin will be loaded after any other Javascript that is used by other plugins and/or themes.

PLUGIN FEATURES:

Some of the features that are included in this plugin are:

• syntax highlighting

• code minification

• revisions

• grouping blocks of code

• including dependencies (libraries such as jQuery and backbone.js)

• elegant editor interface courtesy of ACE

FUTURE ADDITIONS:

Here are some of the things that I will be adding sometime in the future as the plugin grows 🙂 :

• ability to choose your minifier of choice from the minify library

• ability to load different javascript files for each page/post as decided by the plugin user

• ability to save additional javascript files and create tabs to organize the files

• a separate button to completely delete the javascript files from the server

What does the plugin do?

The plugin is just a simple Javascript writing/editing tool that allows the user to create some custom Javascript to their WordPress powered website.

How much experience do I need to use this plugin?

Javascript is not too difficult to pick up. There are many freely available resources online that you can find to help you get started. The site that I used to get started on Javascript is http://w3schools.com/js/default.asp

Does it do anything to the database?

Yes. This plugin allows the use of revisions and will add entries to the database in the posts table. The database is accessed using WordPress and PHP core functions and there are no direct SQL queries.

Does the plugin access the filesystem?

Yes. This plugin will save and delete files to the filesystem. The files will be located in the uploads folder under the sub-folder “global-js” on a default WordPress installation.

Does the plugin work in a multisite configuration?

Yes. The plugin works in a multisite environment as it creates files and folders in the site’s own portion of the uploads directory.

How do I get rid of the javascript files from the server?

At the moment, the only way to do this is to save a blank javascript file. This will delete all the relevant files from your uploads folder. There is currently no way to delete it from your database posts table through the plugin. You will have to access the database and delete it manually. You can find the posts in the data base by searching for post_title = ‘Global JavaScript Editor’ in the posts table.

v0.16 – dependencies such as jQuery are now included in the plugin
– the current libraries can be included by ticking the checkbox in the editor
– included a function call to clear cache on save if supercache is enabled

v0.15 – plugin now minifies the javascript using the Google Closure Compiler at simple settings included in the PHP minifier library
* Julien’s note: if you want to change which minifier to use go to the filter function in the code
– changed the way files are saved and loaded to account for the extra time to minify the javascript

v0.14 – plugin no longer does anything on activation and deactivation (not necessary to)
– no longer creates a separate directory
– changed the way older files are deleted

v0.13 – changed the behavior of the deactivate function. (does not depend on the host being UNIX based)
– added a recursive function that handles removing directories and the contents inside the directories

v0.12 – added 2 additional hooks that will add and delete directories upon activation or deactivation respectively
– defined the uninstall function though at the moment nothing calls it (need to do additional testing and research before enabling it)

v0.11.1 – added a conditional to only load the javascript if the files exist

v0.11 – added a conditional to check if WP_DEBUG is set to true
* if WP_DEBUG is true plugin will load the non stripped version of the javascript

* this new method should work regardless of what the parent directory is called
