The Science of Functional Programming

This is the official source repository for the new book The Science of Functional Programming: A tutorial, with examples in Scala.

The book is a tutorial exposition of the theoretical knowledge that functional programmers need. The material is developed from first principles and contains complete explanations, derivations, and proofs of almost all required results.

A recorded slide presentation, “Reasoning about types and code”, illustrates some of the topics and methods of this book.

Building a PDF version of the book from LyX sources

The current PDF build is available as sofp-src/sofp.pdf.

If you want to build from source, currently you need LyX 2.3.x and pdftk installed.

bash make_sofp_pdf.sh builds the PDF file sofp.pdf.

If you do not have LyX, you can simply build from the provided LaTeX sources using commands such as

latex sofp.tex
latex sofp.tex
latex sofp.tex
makeindex sofp.idx
latex sofp.tex
latex sofp.tex
dvips sofp.dvi
ps2pdf sofp.ps
