CDSoft - Software made simple, verifiable and usable

About CDSoft

CDSoft used to be my personal website where I stored and shared some free softwares and other funny pieces of softwares.

My main objective is now to propose a way to specify and write softwares that are:

while remaining:


Old version of my project

I had initially planned to write a book about software specifications. But the project was not funded on Kickstarter.

You can find some ideas about writing documents and specifications

My initial goal was certainly too general and too wide.

Current work

I’m currently working on a simulation framework based on Haskell.

The idea is quite simple:

One objective is also to provide a portable build and execution environment. e.g.:

Enforcing the usage of some huge and insane environment is clearly not compatible with my philosophy and is bad for my mental health!


and in fact:

What’s currently working?

Still missing components

…and a decent documentation…

Side effects

I have previously said that side effects are bad. But this project already has a nice side effect indeed.

My documents are written in Markdown and I use Pandoc to generate HTML or PDF documents. Pandoc is fabulous but it misses a good preprocessor. I wrote my own text preprocessor which is available here: (pp is obsolete, please check instead).

This preprocessor (abp) also prepares pages of this website.


I have a strong experience in critical domains in aeronautics (DO178B, specification, implementation, verification).

I’m currently working at EasyMile where I’m developing a critical software in C. The simulation and test environment is fully made in Haskell using some of the principles presented in this page.
