FASTyle 2.3

25 Jul 2016 Edited
FASTyle is an all-in-one suite which dramatically improves and speeds up assets management, including templates, stylesheets and javascripts. FASTyle is equipped with a powerful editor and asset manager, giving you fine control over theming development in a single browser tab.

Minimum requirements

PHP 5.4
MyBB 1.8.0
664 chmod on [admin dir]/modules/style/themes.php

AJAXed interface

FASTyle is built with speed in mind; as such, every action you take is routed to the server with AJAX technology, accounting for its unique real-time feel. Assets are listed in a convenient collapsible sidebar, and once loaded they are added to a tabbed top bar where you can easily switch between opened ones, resembling a standard browser experience. Get, save, add and delete assets anytime and in real-time.

SPARKLES use the CTRL/CMD+S combination to quickly save assets.

Semantic template listing

Struggling to find that particular template you want to edit? Fear no more. FASTyle displays templates semantically, with a parent > child structure you'll love. And the search bar is always there to help you anytime you need.

Diff comparator

Compare assets to their original versions and edit them as you type. Templates and stylesheets are compared against the local MyBB Master Style versions, while JavaScripts are compared remotely by fetching the original asset from GitHub synchronized with your current MyBB version.

Quick mode

When you perform sensitive actions, like closing unsaved assets or deleting them, you are prompted with a confirmation dialog. Quick mode allows you to bypass dialogs and approve your actions automatically, like a pro.

WARNING SIGN By enabling quick mode you acknowledge that you can permanently delete assets without any confirmation dialog. Templates and stylesheets are saved in the database, so you *might* have automatic backups generated by MyBB's tasks system; JavaScripts are saved in the filesystem and are more prone to data loss.

State memory

FASTyle remembers your editor tuning, including previously opened tabs and the last one being worked on, quick mode and full paging, and sets them automatically once you refresh the page or come back days after. FASTyle's memory is stored in your browser cache and it's theme's specific, so you can work on different themes without letting their own setups interfere with each other.

Stylesheets quick reordering

Drag and drop stylesheets and reorder them wherever you want. In the current version, stylesheets' order is saved automatically after 4 seconds from the last drop.

Distractions-free mode

Aka: full paging. It allows you to work better by having zero distractions over your coding sessions.

Custom theme

A custom and handmade theme is included to rest your eyes in delight while managing your beloved MyBB board.

Sublime Text keymap

FASTyle adds the popular Sublime Text keymap to CodeMirror: here you can find the complete list of keyboard shortcuts you can use to improve your template and stylesheet management.

Revamped find and replace

A revamped find and replace module for CodeMirror is included. This is one of the hottest features included in FASTyle, as CodeMirror's standard functionality lacks friendliness and it's one of the biggest bottlenecks faced by its users. FASTyle's version works much like any advanced code editor for OSes, persisting on screen after the search, highlighting matches properly and in real-time.

Templates should be listed already:

To switch back to 1.7: download it from here or the Mods Site (the GitHub one has some patches applied before splitting into a separate branch, so shouldn't be used), uninstall 2.0, remove all 2.0 files, upload 1.7 and install.

Nope, no templates at all - ignore the Zinc templates - it cannot be deleted somehow, there is no default theme templates showed :(

Can you provide me a temporary FTP account? This is something I may need to debug directly. Thank you!
Eldenroot 8 Oct 2017
@Shade - yes, I can, are you on MyBB discord? I will be there ASAP

Does this work with the Themes instead of Templates. I feel the Editor for the .CSS files are a bit slow and impairs me to do my work sometimes with long page times and scrolling is slow.

Hi @Khaleesi Hale, FASTyle 2.0 lets you handle stylesheets as well and it also solves the slowness you can experience with the default setup.

Loving it Shade.
Only thing that stands out for me is the sidebar for 2.0
