Antarnisti Smiley for Kaskus adds a collection of smiley shortcodes for Kaskus-style emoticons to WordPress content and comments. It also provides a Classic Editor button and an optional smiley picker below the comment textarea.
This plugin is not affiliated with, endorsed by, sponsored by, or officially connected to Kaskus. Kaskus is a trademark/project name of its respective owner. The name is used only to describe the style and compatibility target of the smiley set.
This 2.5.0 maintenance build changes the plugin name and text domain to a clearer third-party naming pattern, keeps the cleaned-up codebase for newer WordPress versions, and sanitizes the smiley HTML returned by content/comment callbacks.
It also includes an option to disable WordPress native emoji scripts and styles, which is useful when this plugin is used as the site’s primary smiley/emoji system.
Important asset note: this package contains Kaskus-style image assets. Before distributing this plugin publicly, make sure every bundled image asset has a GPL-compatible license or written permission for redistribution under WordPress.org plugin directory rules.
