A library for creating QtQuick/QML GUI applications in OCaml and Reason, providing bindings and a PPX syntax extension.
Lablqml is a library that enables developers to write QtQuick/QML graphical user interfaces in OCaml and Reason. It provides a bridge between OCaml's functional programming strengths and QtQuick's modern declarative UI framework, allowing for the creation of cross-platform desktop applications with rich, dynamic interfaces.
OCaml or ReasonML developers who want to build cross-platform desktop applications with modern, fluid, and animated graphical user interfaces using QtQuick.
Developers choose Lablqml because it integrates QtQuick 2 with OCaml's functional programming model via a PPX syntax extension, avoiding the complexities of Qt Widgets bindings and focusing on a seamless declarative UI development experience.

Uses a PPX rewriter (ppx_qt) to automatically generate C++ code from OCaml source, simplifying the integration process as demonstrated in the demos directory.
Leverages QtQuick 2 for building rich, dynamic interfaces that run on multiple desktop platforms, supported by the library's integration.
Enables OCaml and ReasonML developers to apply functional paradigms to GUI development, integrating logic with declarative QML, as shown in the minimal example.
Includes demo applications like qocamlbrowser, which replaces Tcl/Tk with QtQuick, providing real-world usage examples to accelerate learning.
Explicitly avoids QtWidgets bindings, limiting use cases where traditional desktop UI components are needed, as admitted in the README.
Requires manual linking with multiple Qt libraries (e.g., -cclib flags in the minimal example), making the build process error-prone and cumbersome.
Being a specialized bridge between OCaml and QtQuick, it has a smaller user base and fewer resources compared to mainstream GUI frameworks.
Requires Qt installation (>=5.3) and a C++ compiler, adding external dependencies that pure OCaml projects typically avoid.
