singularity-calculator

Important

Report bugs and request features in the Singularity Desktop tracker.

A calculator app for the Singularity Desktop Environment.

Requirements

• Meson ≥ 0.59
• Vala compiler
• Vetro compiler
• GTK4
• libgee-0.8
• libsingularity

Build & Install

meson setup build
meson compile -C build
meson install -C build

The project resolves libsingularity through a Meson subproject fallback, so it is normally configured from the singularity-desktop tree rather than on its own.

Tests

CalculatorEngine (src/engine.vala) holds every bit of arithmetic and depends on nothing but GObject and libm, so it is covered by a headless test binary:

meson test -C build --suite singularity-calculator

Use of Generative AI

Maintainers may use generative AI tools as assistants while working on singularity-calculator. Non-trivial assisted commits disclose the tool, model, and scope of the work.

AI tools may assist with code comments, documentation, repetitive code, and issue triage. Maintainers make project decisions and review every assisted change before it is merged.

Use these trailers for non-trivial assisted commits:

Assisted-by: <tool>:<model-version>
AI-Scope: <what the tool generated and the prompt or a short prompt summary>

Single-line completions, renames, and formatting changes do not need trailers.

Coding agents must also follow AGENTS.md before changing files, creating commits, or opening pull requests.
