linebender/xilem

2026-04-14T00:00:00+00:00

Xilem is a high-level reactive framework inspired by React, SwiftUI and Elm. It lets users create a lightweight view tree, and changes the rendered app based on changes to the tree. It has a web backend and a Masonry backend.

Masonry is a foundational crate for building natively compiled GUIs in Rust. It provides a retained widget tree and runs event handling and update passes on it.

This is the project I’ve contributed most prolifically to, as I use this for all my GUI endeavors and find it joyful to work with the project and the community, both.

endoli/understory

2026-03-28T00:00:00+00:00

Understory is a small family of crates designed to be combined in different stacks over time, that provides foundational spatial and scene data structures for user interfaces, graphics editors, and CAD viewers.

My contribution was to the understory_virtual_list</code> crate that provides abstractions for 1D virtualization primitives, in particular, adding support for sparse lazy loading of list items.

It is a Quran reader app that automatically scrolls the text for hands-free, uninterrupted recitation.</p>
I built it mainly for personal use in Ramadan of 1447 AH, and did two full recitation of the Holy Quran using this.</p>
It uses resources from the Quranic Universal Library (QUL)</a> by Tarteel.ai, in particular the DigitalKhatt</a> font by Dr. Amine Anan which is a digitized replica of the calligraphy by Master Calligrapher Uthman Taha in the 1441H mushaf from King Fahad Glorious Quran Printing Complex.</p>
This project is written in Rust using Xilem</a> GUI library from Linebender</a> and brought the opportunity for a few community contributions, involving the understory</code></a> crates.</p>

It is an input method editor (IME) for Windows that implements Avro Phonetic</a> scheme using Windows Text Service Framework and Rust.</p>
It is loosely based on the sample IME from Windows classic samples</a> and its partial Rust port</a>. Phonetic conversion uses rupantor</code></a> by the OpenBangla project.</p>


tackler-ng/tackler
2025-01-10T00:00:00+00:00
Tackler is a plaintext accounting software (like Ledger</a>) written in Rust that has built-in integrity check</p>
I added the initial market price analysis (PriceDB) support to Tackler, which then have been further developed.</p>


itt-ustutt/num-dual
2024-11-14T00:00:00+00:00
num-dual</code> is a Rust library that provides generalized, recursive, scalar and vector (hyper) dual numbers for the automatic and exact calculation of (partial) derivatives.</p>
I have been looking into it for a curve research</a> and needed quadrant-preserving arctangent (atan2</code>) calculation for second order dual numbers and just added that.</p>

It is an app for visualizing audio files in a manner like colorful raindrops in a pool of black water.</p>

Motivation to work on this struck me as I was thinking of learning GPU programming concepts, an here it is!</p>


dfrg/swash
2023-05-01T00:00:00+00:00
Swash is a pure Rust, cross-platform crate that provides font introspection, complex text shaping and glyph rendering.</p>
I fixed a (trivial) issue with unaligned pointer read (rightfully) causing panic.</p>


lapce/floem
2023-05-01T00:00:00+00:00
Floem is a native cross-platform Rust UI library with fine-grained reactivity inspired by Leptos</a>.</p>
It is the UI library that powers the Lapce</a> code editor.</p>
I fixed non-standard text input behavior on Windows when using non-standard input method editors (IME) that hooks keyboard events directly, like Avro Keyboard</a> which I used heavily at that time.</p>
However, I’ve switched to my homegrown replacement</a> of it that uses proper IME framework.</p>


fschutt/printpdf
2023-03-09T00:00:00+00:00
printpdf</code> is a Rust library for creating, reading, writing and rendering PDF documents.</p>
I has been intending to use this library to render some PDF documents, but found some issues with how it rendered complex-script texts.</p>
I brought this codebase up to Rust 2018 edition in anticipation of improving the text rendering issue, but found out about Typst</a> at the same time.</p>
Thus that sadly remains my only contribution to this codebase.</p>

It is small Windows app that lives as a notification area icon and shows prayer times using adhaan</code></a>.</p>
</p>
It is written in Rust using the Druid</a> GUI library. Working on this lead to my first serious foray into community contribution in the Linebender</a> community.</p>
This project is currently on hiatus. I’m in the process of porting it to Xilem</a>, which is the successor of Druid.</p>

It is a Rust library for calculating prayer times. It originally started as a fork of salah</code></a>, which I and have been using for making a GUI and [Azzam S.A.] was using to make a TUI, but has been causing us lots of pain.</p>
salah</code> was ported to Rust by Farhan Ahmed from Adhan</a> by BatoulApps. May Allah grant him bountiful rewards.</p>
Key differences between salah</code> and adhaan</code> are:</p>

adhaan</code> extensible in regard of calculation method.</li>
adhaan</code> uses jiff</code> for its date-time vocabulary, in stead of chrono</code>.</li>
</ol>
Motivation for this arose when I started to work on [AdhaanGUI] and although whereas AdhaanGUI itself is on hiatus, I use both adhaan</code> and AdhaanGUI frequently.</p>


Data Importer TUI
2017-10-03T00:00:00+00:00
It was a data entry and import solution to a government data management system, that has been designed and used internally.</p>
Web UI of the target system was very cumbersome and slow, 3-5x slower than one-by-one entry with the TUI, up to 10x slower when doing bulk upload. This lead to me designing and optimizing it for easier data entry first in JavaScript using NodeJS and later using Rust.</p>
Its working procedure involved:</p>

Logging into the service</li>
Composing a HTTP POST request for a new data</li>
Appropriately fetching and displaying the captcha in command line</li>
Submitting the captcha</li>
</ol>
This data importer took approximately 25 person-hours of development and maintenance time and saved about 65 hours in usage, netting on 40 hours saved in total.</p>
This project was a proprietary one and is no longer maintained.</p>
