Open Source Haskell Business Software

patat (Presentations Atop The ANSI Terminal) is a small tool that allows you to show presentations using only an ANSI terminal. It does not require ncurses. Leverages the great Pandoc library to support many input formats including Literate Haskell. Supports smart slide splitting. Slides can be split up into multiple fragments. There is a live reload mode. Theming support including 24-bit RGB. Auto advancing with configurable delay. Optionally re-wrapping text to terminal width with proper indentation. Syntax highlighting for nearly one hundred languages generated from Kate syntax files. Experimental images support. Supports evaluating code snippets and showing the result. Written in Haskell.

Command-line Kanban board/task manager with support for Trello boards and GitHub projects. A CLI kanban board/task manager for Mac and Linux. Per project task lists, vim style key-bindings, stored using Markdown. Clean diffs for easy version control, support for sub-tasks and due dates, Trello board imports, and GitHub project imports. If you’re using a simple two-column “To Do” and “Done” then use the space bar to mark an item as complete while staying in the “To Do” list. If you’re using a more complicated column setup then you will want to use H/L to move tasks between columns. By default times are stored in the Markdown file as UTC. If you would like local times (and are unlikely to open the file in lots of different timezones) then you can set localTimes to true in the markdown section of the config file.

HStreamDB is an open-source, cloud-native streaming database for IoT and beyond. Modernize your data stack for real-time applications. By subscribing to streams in HStreamDB, any update of the data stream will be pushed to your apps in real-time, and this promotes your apps to be more responsive. You can also replace message brokers with HStreamDB and everything you do with message brokers can be done better with HStreamDB. HStreamDB provides built-in support for event time-based stream processing. You can use your familiar SQL to perform basic filtering and transformation operations, statistics and aggregation based on multiple kinds of time windows and even joining between multiple streams. With connectors provided, you can easily integrate HStreamDB with other external systems, such as MQTT Broker, MySQL, Redis and ElasticSearch. More connectors will be added.

The Fluxion framework is a prototype data integration system using Semantic Web technologies.

A small command-line calculator, written in Haskell, that takes input like "14+(12+24)/(8.5-2.5)" and prints out the result. It's nothing special really, just a little project I did to learn Haskell.

This is a set of scripts for Project Management implemented in Haskell

Quantative Finance structures and algorithms in Haskell

Toodles is a dead-simple, self-hosted web-based to-do list application that scans your codebase for TODO comments and displays them in a clean dashboard. It helps developers keep track of pending work scattered across files, making it easier to manage technical debt and pending improvements.

powerPlant is a plant modelling tool based on parametric plant descriptions, producing highly detailed models that can be exported to 3ds. Deriving similar plants is a matter of 1 click! Complete scenes can be composited with the integrated scene editor.
