Shaarli Markdown Toolbar Plugin

Shaarli plugin to easily insert markdown syntax into the Description field when editing a link.

Tested on Shaarli 0.11.1 with the Shaarli-Material and the built-in default themes using desktop and Android Chrome browsers. Should be compatible with Shaarli 0.12.0-beta as well which introduced a major internal rewrite (#1511).

Features

• Displays a markdown editor toolbar above the Description field when adding or editing a link
• Shows the current description's character count below the textarea (can be useful for e.g., Twitter publishing)
• Supports distraction-free writing in fullscreen mode
• Works well on both desktop and mobile
• The editor has built-in translations for 23 locales
• Plugin Administration page integration for easy configuration
• All plugin dependencies are included in the local setup to respect privacy and do not leak HTTP referrer. Existing licenses are distributed with the included files. See the Credits seciton for attribution.

After plugin enabled and the Shaarli Descriptor Plugin's DESCRIPTION_ROWS parameter is set to 12 to have more vertical space in the editor area:

Fullscreen mode

Distraction-free writing can be enabled by clicking on the fullscreen button while editing a link:

Usage

• Select some text and click on any of the toolbar buttons to apply formatting.
• If you click one of the buttons without previous selection, you get a corresponding default text with the desired formatting applied to it. The selection is then moved to the default text for quick replacement.
• Bold, italic, heading, code and quote buttons support a 2nd click when all its contents are selected to remove the formatting from around the text. Only the inside text should be selected in this case.
• The plugin has built-in translations in 23 languages for the toolbar buttons and default texts. See the Configuration section here on this page for further info how to enable localization.
• Works best with the Shaarli Descriptor Plugin when DESCRIPTION_ROWS is set around 12.
• The built-in markdown plugin is not a prerequisite to activate the Markdown Toolbar, however, it is recommended to turn it on to see the formatted results after saving.

Installation

The plugin's folder (markdown_toolbar) should be placed in the <shaarli>/plugins/ directory.

The directory structure should look like:

└── plugins
    └── markdown_toolbar
        ├── includes/...
        ├── markdown_toolbar.html
        ├── markdown_toolbar.meta
        └── markdown_toolbar.php

To enable the plugin, just check it in the Plugin Administration page (?do=pluginadmin).

You can also add markdown_toolbar to your list of enabled plugins in data/config.json.php.\ The general.enabled_plugins list should look like then:

"general": {
  "enabled_plugins": [
    "markdown_toolbar",
    [...]
  ],
}

Configuration

Go to the Plugin Administration page, and edit the following settings (with the plugin enabled):

• MD_TOOLBAR_LOCALE\ Localization of the editor. Default: en\ Example value: hu\ Supported values: en, ar, cs, da, de, fa, fr, hu, it, ja, kr, nb, nl, pl, ptBR, ru, sl, sv, tr, ua, zh-tw, zh. If not specified or malformed, defaults to en.

Note: this setting can also be set in data/config.json.php, in the plugins section:

"general": {
    "plugins": {
        "MD_TOOLBAR_LOCALE": "ja",
        [...]
    },
}

Known issues

• There is a bug in Shaarli's Router.php:L125-131, hence there is no backend way to detect the difference between the addlink and the edit_link pages. Because of this issue, I needed to add autofocus:true to the editor generally when the page loads.
• When the built-in vintage theme is active, the editor works but has smaller issues (see below) that I am not going to fix right now. This theme does not have a CSS identifier that one can use to bind styles to it (such as the default theme has its .pure-g class).
  • The editor does not well fit the editlink form
  • The "exit fullscreen" button is positioned out of the screen
  • The "enter fullscreen" button is misplaced on some mobile resolutions
• Any other issues that the Bootstrap Markdown editor has can be present here though I tried to fix some of them locally.

If you fix an issue from the list or some newly discovered one, please open a pull request here.
