Squirtfilter is a powerful ruleset language developed for Siyuan AdBlocker, a successor to AdBlock Plus and uBlock Origin. It is a more performant filter than any other available filter to date. With Squirtfilter, you can block advertisements, popups, and unwanted content on any website, all while enjoying a smooth and uninterrupted browsing experience.
Before we delve into the syntax and use cases of Squirtfilter, let's talk about its unique name. The name Squirtfilter was inspired by the "squirt" sound that is made when a water pistol or squirt gun is fired. The idea behind the name is to represent the speed and precision of the filter, just like a water pistol that quickly and accurately squirts water.
The syntax of Squirtfilter is similar to that of other popular filter syntaxes like Adblock Plus, uBlock Origin, and EasyList. Here's an example of a Squirtfilter rule that blocks all ads on a website:
||example.com^$document
In this example, the || prefix signifies that the rule should be applied to the domain that follows, which is example.com. The $document suffix indicates that the rule should apply to the entire document of the website.
Squirtfilter also supports more advanced syntax, such as regular expressions, wildcards, and exceptions. Here's an example of a more complex rule that blocks all images on a website, except those with a specific URL pattern:
example.com##img[src$=".jpg"]:not([src*="specific-url"])
In this example, example.com is the domain to which the rule should be applied. The ## prefix signifies that the rule should apply to an HTML element, which in this case is the img element. The :not pseudo-class is used to exclude images that contain the specified URL pattern.
Squirtfilter is a powerful tool for customizing and enhancing your browsing experience. Here are some of the common use cases of Squirtfilter:
Blocking ads: Squirtfilter is especially useful for blocking ads on websites. By using Squirtfilter rules, you can remove annoying and distracting advertisements and enjoy a clean and clutter-free browsing experience.

Squirtfilter is a powerful and easy-to-use ruleset language that can enhance your browsing experience and protect your computer from malicious content.
