Introduction 👀

Sequel Filter is a C# library that allows for filtering using a SQL-like syntax. The idea is to be able to provide end-users with completely customizable filtering without having to allow them to provide their own code or write your own filtering logic.

Library Features 📚

• Simple injection-free filtering logic
• Support for matching single objects or filtering IEnumerables
• Lightweight dependencies (only Irony parser required)

Grammar Features ✍

• Basic comparisons with support for loose type matching
• Combinational logic with AND / OR
• Support for IN, LIKE, BETWEEN and IS NULL SQL operators
• Support for searching child enumerables with HAS_NONE, HAS_ANY, HAS_SINGLE

Documentation Sections 📖

• Grammar - covers the grammar that you can use to filter objects with some examples.
• Code - how to integrate Sequel Filter into your project to allow filtering of objects.
• Contributing - covers useful information for anyone who wants to contribute to the project.

Support 🤝

If you’d like to support the project but you don’t want to contribute code - a really good way to help is spread the word. There isn’t a donation or financial option because honestly I don’t need donations. I am, however, rubbish at ‘marketing’. So any help there would be greatly appreciated! Whether it’s a blog post or just telling some folks at the office - every little helps.
