INF220 - Programspesifikasjon
Contents on this web page
The course couples theory to practical programming in Magnolia.
Magnolia is a new programming language tightly integrating
specifications and code
with a foundation in institution theory.
It supports high integrity programming (reliable, robust, safe, secure)
by validating correctness and guarding every operation.
The course will cover topics like the following.
- Algebraic specifications as a means of defining API (application programmer interface) contracts.
- Institutions as a means of understanding modularisation, reuse and testing.
- Generic programming for reuse and correctness testing.
- Data invariants and congruences as a means for data abstraction and verification.
- Assertions as a means of understanding algorithms.
- Pre-/post-conditions as a means of understanding methods.
The curriculum consists of
all lectures, notes, handouts, exercises, and related course material,
most of it will be covered in the following handouts
(to be made available later).
- Magne Haveraaen: Magnolia Semantics - alpha release. 2018.
- Magne Haveraaen and Anya Bagge: Magnolia Tutorial - alpha release. 2018.

Teaching assistant: TBD
The participants are adviced to organise study groups for discussing
the topics of the course and assist each other in solving the exercises.
See the official schedule, subject to change:
Teaching starts Monday August 20 2018 (week 34),
Teaching will be in the form of lectures, exercises and
time off for self studies.
The HiB building (Høyteknologisenteret i Bergen) is Thormøhlensgt 55, 5008 Bergen.
The room is in datablokken, the taller of the two towers (to the right of the main entrance).
The following teaching plan is very tentative and guaranteed to change.
- Mondays 1215 - 1400 in seminar room 405O2 HiB (the aquarium)
- Wednesdays 1015 - 1200 in seminar room 405O2 HiB (the aquarium)
- Fridays 1215 - 1400 in seminar room 405O2 HiB (the aquarium)
The exam is planned for the end of November/beginning of December.
The exercises will be provided as the course evolves,
The course will probably be evaluated by an oral exam.
