/*
* TweakDrag -- auto-scroll the board while dragging a card near a screen edge.
*
* Kanboard drags cards with jQuery UI sortable. The board does not scroll during a drag
* (jQuery UI's autoscroll is unreliable horizontally, and on touch the bundled Touch Punch
* shim suppresses native scrolling while a card is held), so you can only drop onto columns
* already on screen. This scrolls #board-container while a card drag is active and the
* pointer nears the left/right edge, with a smooth continuous speed that grows toward the
* edge -- so you can drag a card to the edge and roll the board to a far column.
*
* It only acts during an active card drag near an edge, so it is harmless when idle. Works
* on desktop (mouse) and mobile (touch, via Touch Punch). No core changes.

# Skeleton -- a Kanboard plugin template # TweakDrag -- board drag, touch and column-gap tweaks
A minimal, working Kanboard plugin that you copy and rename as the starting point for a A Kanboard plugin that groups board dragging and spacing tweaks, configurable under
real plugin. By itself it does only one trivial thing: it renders the word "Skeleton" at "Settings -> Tweak Drag":
the top of every page. It changes no data and runs no database migration.
## What it demonstrates - **Drag the board background to scroll** (desktop) -- click and drag on the empty board
background to scroll the columns sideways, like the Trello board canvas.
- **Widen the gap between columns** -- spread the columns further apart, easier to tell
apart and to touch.
- **Mobile drag handle size** -- enlarge the card drag handle Kanboard shows on mobile so
it is easy to grab with a finger.
- **Drag auto-scroll** -- while dragging a card, the board scrolls when the pointer nears a
screen edge, so you can reach a column that is off screen (desktop and mobile).
- A complete `Plugin.php` registration class with all the metadata Kanboard shows in These options were originally part of the ShrinkVertically plugin and moved here so that

- Asset hooks (`template:layout:css` and `template:layout:js`) that load a stylesheet and
a script. They are empty for now but prove the injection path works -- handy when a real ## How it works
plugin needs custom CSS or JS.
- The standard plugin directory layout, with stub folders (`Controller/`, `Model/`, - **Drag to scroll**: a small script (`Asset/js/drag-scroll.js`, loaded only when the

empty background -- pressing a task card, a drag handle or any control is ignored, so
Kanboard's own card and column drag-and-drop keep working unchanged.
- **Column gap**: the board is a table, so the gap is set with `border-spacing` (injected
in the page head from `Template/layout/variable.php` only when the option is on), sized
by the `--td-column-gap` CSS variable. This spreads the columns without shrinking the
cards and keeps each column header aligned with its list. It also adds some spacing at
the left and right edges of the board.
- **Mobile drag handle size**: Kanboard already supports dragging cards on mobile, but only
via a small handle (a FontAwesome `fa-arrows-alt` glyph it reveals on touch devices) that
is hard to grab. FontAwesome icons are sized by `font-size`, so a single rule scales the
handle from the `--td-handle-size` CSS variable. It is inert on desktop, where Kanboard
keeps the handle hidden.
- **Drag auto-scroll**: a script (`Asset/js/drag-autoscroll.js`) listens for jQuery UI
sortable's `sortstart`/`sortstop` (which also fire on touch via Kanboard's bundled Touch
Punch) and, while a card drag is active, scrolls `#board-container` when the pointer nears
its left/right edge. Speed ramps up smoothly toward the edge. After each scroll step it
dispatches a synthetic `mousemove` so jQuery UI moves the drop placeholder onto the newly
revealed column. It only acts during an active drag, so it is idle otherwise.

## Installation ## Installation
No build step and no dependencies. Copy this folder into your Kanboard installation as `plugins/TweakDrag/`. The directory
name must be exactly `TweakDrag` (Kanboard derives the plugin namespace from the folder
name). No build step and no database migration.
1. Copy this folder into your Kanboard installation as `plugins/Skeleton/`. ## Settings
2. Reload any page. The word "Skeleton" appears at the top.

- **Widen the gap between columns** -- toggles the wider gap. Default: on.

## How to fork this into a new plugin
1. Copy the folder and rename it, e.g. `plugins/MyPlugin/`. The folder name must match the
namespace and start with a capital letter.
2. In `Plugin.php`, change the namespace from `Kanboard\Plugin\Skeleton` to
`Kanboard\Plugin\MyPlugin`.
3. Update the metadata methods (`getPluginName`, `getPluginDescription`, `getPluginAuthor`,
`getPluginVersion`, `getPluginHomepage`, `getCompatibleVersion`).
4. Update the hook target paths: the lowercase prefix in `'skeleton:layout/header'` and the
`plugins/Skeleton/Asset/...` asset paths must match the new plugin name.
5. Replace `Template/layout/header.php` with your real template, or attach to a different
hook. See the Kanboard plugin hooks documentation for the full list of hook points.
