A Case Study in Dependent Type Theory: Extracting a Certified Program from the Formal Proof of its Specification

Thesis

LaTeX code for template taken from https://github.com/echo-uib/master-latex-template.

See .tex-build/main.pdf for pdf.

Formalization

Build Coq files

Proof of main theorem (Theorem 3.2) is located in coq/src/Main.v. Haskell extraction, along with some examples (and minor manual code changes, see thesis 5.1.2), is located in coq/extr/Main.hs. The largest example uses type universe constraints taken from Main.v using Print Universes.

cd coq
make -f CoqMakefile

Running the above command will also re-extract the file Main.hs, thus removing some changes (done manually for QOL)!

Compile & run Haskell example

coq/extr/Main.hs can be compiled with Stack for much better efficiency.

cd coq/extr/stack-proj
stack run
