I’ve been doing a pass on the structure, and I was thinking on a rough structure as follows:
1) Intro to FFI (callouts, function and library lookup, intro to value marshalling)
2) Marshalling (sending arguments, literal arguments, more on marshalling, basic C types: ints, floats, pointers and how they are transformed to pharo objects and vice-versa…)
3) Complex types: strings, unions, arrays, opaque types
4) Derived types on the Pharo side: How to design nice classes with all this
6) Memory management
I did already a pass on 1), and I got blocked in 2), though I want to release a version of it this week.
If you’re up for it, there are several things we can do:
- review the english :)
- give feedback on what is missing, what is not understandable, what can be explained better
- testing the examples?

Pillar is a markup syntax (from Pier’s CMS, if you know it).
Pillar comes with a document model, parser and generators to html, pdf (through latex), and others…
In Pillar’s readme there are the installation instructions + usage.
If you check the travis file in the ffi booklet repository
You’ll see it is built with pillar 7.4.1. In other words
# install pillar
$ git clone https://github.com/pillar-markup/pillar.git -b v7.4.1
$ cd pillar && ./scripts/build.sh && cd ..
# go into the booklet repository and build the pdf
$ ./pillar/build/pillar build pdf
Although you’ll need a mostly up-to-date latex version (latexmk required, plus several other packages, check Pillar’s readme)

And it’s super important nevertheless ^^.
