MaPS - MaRDI Packaging System

Introduction

MaPS, short for MaRDI Packaging System is the working name for the software system created by TA1 Computer Algebra for Measure 1.4 Predefined software environments. MaPS provides a unified interface both, to package a software inside a functional environment (called a runtime), and to "install" a published runtime onto a computer system in a user friendly way, while still keeping it separate from the computer's host environment.

Requirements

We depend on the following other programs and libraries:

  1. libcairo2-dev
  2. gcc
  3. python3-dev
  4. libgirepository1.0-dev
  5. libostree-dev
  6. pygobject
  7. bubblewrap
  8. tomli
  9. tuspy
  10. progress

Technical Overview

Deploying Software

We deploy software in $HOME/.var/org.mardi.maps/remote/app-id/, in directories rofs, and rwfs. Ostree repo is checked out in rofs, and marked as read only. Then rwfs is overlayed on rofs at runtime. This way the user gets a live mutable tree, but the actual ostree repo is left unmodified and can be reverted to.
