See Release Notes for more information.

Description

This extension provides support for applications written using Fortran languages.

Although this extension is officially supported by CAST, please note that it has been developed within the technical constraints of the CAST Universal Analyzer technology and to some extent adapted to meet specific customer needs. Therefore the extension may not address all of the coding techniques and patterns that exist for the target technology and may not produce the same level of analysis and precision regarding e.g. quality measurement and/or function point counts that are typically produced by other analyzers.

In what situation should you install this extension?

If your application contains source code written using Fortran and you want to view these object types and their links with other objects, then you should install this extension.

Supported Fortran versions

This version of the extension provides support for:

Fortran	Supported
Fortran 77	✅
Fortran 90	✅
Fortran 2003	✅

Function Point, Quality and Sizing support

Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Function Points (transactions)	Quality and Sizing
✅	✅

Compatibility

Release	Operating System	Supported
v3/8.4.x	Microsoft Windows / Linux	❌
v2/8.3.x	Microsoft Windows	✅

Supported file types

Only files with following extensions will be analyzed:

*.for
*.FOR
*.inc
*.INC
*.pfo
*.PFO
*.f
*.F
*.f03
*.F03
*.f90
*.F90
*.f77
*.F77
*.h (.h files are used as include files, however for the most part, *.inc are used as include files)

Below is the list of extensions that will enable you to tell what type of Fortran is provided:

Fortran version	Extension
Fortran 2003	`.f03`, `.F03`
Fortran 90	`.f90`, `.F90`, `.g90`, `.f95`, `.F95`, `.g95`, `.f`, `.F`, `.for`, `.FOR`
Fortran 77	`.f77`, `.F77`, `*.g77`,

Download and installation instructions

The extension will be automatically downloaded and installed when at least one of the supported file types is delivered for analysis.

Source code discovery

A discoverer is provided with the extension to automatically detect Fortran code: when one of the supported file types is found in a folder, one “Fortran” project will be discovered, resulting in a corresponding Universal Technology Analysis Unit.

Tools

Fortran Preprocessor

Fortran source code needs to be preprocessed so that CAST can understand it and analyze it correctly. This code preprocessing is actioned automatically when an analysis is launched or a snapshot is generated (the code is preprocessed before the analysis starts). The Fortran Preprocessor log file is stored in the following location:

%PROGRAMDATA%\CAST\CAST\Logs\<application_name>\Execute_Analysis_<guid>\com.castsoftware.fortran.<_extension_version>.prepro_YYYYMMDDHHMMSS.log
