Spindle - Nickel Configuration Parser

Note: This directory is named ada-loom-registry but contains a Haskell project called "Spindle" - not an Ada project.

What is Spindle?

A Haskell-based tool for parsing and evaluating Nickel configuration files. It reads .ncl files, evaluates them, and converts them to Haskell types via JSON.

Technology Stack

cabal build
cabal run spindle -- path/to/config.ncl

Configuration

• config.ncl - Nickel configuration

• config.toml - TOML configuration

• .gitlab-ci.yml - CI/CD pipeline

Purpose

Development

The project appears to be in early development: - Placeholder author/maintainer information - GitHub URLs point to example repository - Minimal changelog entry

Recommendation

This project should be renamed to reflect its actual purpose: - Current name: ada-loom-registry (misleading - not Ada, not a registry) - Suggested names: - spindle-nickel-parser - nickel-config-tools - spindle-haskell
