SAF Specification Documentation Generation

This document covers the document generation process for the SAF specification. It is intended for SAF developers, not for SAF users.

Concepts and Tools

The SAF Specification is generated into HTML pages from a model. The generation happens in several steps:

  • JSON Files are generated from a document generator Model. The document generation model references the specification model and the example model. The generation itself is accomplished by a combination of some custom model elements and scripts, and is started from the modeling tool.
  • HTML pages are generated from template files in the SAF Specification repository and abovementioned JSON Files. The generation uses Jekyll as generation tool. The template files are mainly written in markdown and use the Liquid template language provided by Jekyll

Github Workflow on SAF Specification Repository

The SAF Specification repository contains a workflow which generates the HTML pages from the JSON and markdown files. It is triggered by commits to the Specification repository.

local document generation (setup)

  • clone the SAF Specification repository to your machine

    git clone https://github.com/GfSE/SAF-Specification.git

  • install ruby,bundler and jekyll

    on linux, it is recommended to setup a user specifc tool chain, not interfering with the system :

     gem install bundler --user-install
 export PATH="~/.local/share/gem/ruby/3.2.0/bin/:$PATH"
 export BUNDLE_PATH="~/.local/share/gem/ruby/3.2.0/gems/"

    local document generation (running)

    Run the document generation starting a local web server and open the saf documentation locally

  • in the cloned repository dir, start the generation 
    bundle excec jekyll serve
  • open http://localhost:4000 with a browser

The pages are updated on change of the files. It takes a while, give or take 15-20 seconds. The update is reported in the shell where you called bundle excec jekyll serve
