Ada Parser and GNAT

Currently the Ada Parser is only available on Windows for GNAT 3.15p. For the full release of Structure101 for Ada will be extending platform support for the Ada Parser. In particular, we will be removing the dependency on the very old GNAT 3.15p release (bear with us, it's there for historical reasons and we know it works ;-).

You should install the GNAT 3.15p compiler along side your current Ada compiler, the two can work satisfactorily side by side. The Structure101 Ada Parser simply requires GNAT 3.15p to create the Abstract Syntax Trees that it parses. GNAT 3.15p installation will not interfere with your existing Ada compiler installation.

Get Started By Creating a Structure101 for Ada Project

Creating an implementation model of an Ada project is performed in the following main steps.

  1. Compile your project using Gnat 3.15p.
    • Use the GNAT ASIS libraries to create Abstract Syntax Trees (.adt files) for your project.
  2. Run the Ada parser on your project.
    • Walks the Abstract Syntax Tree files created in step 1.
    • Creates a headway .hwa file.
  3. Start the Structure101 for Ada client application and create a new project specifying the .hwa file generated in step 2, as well as other options offered by the wizard.
