Summary: This document provides information about the extension providing Fortran support.
Extension ID
com.castsoftware.fortran
What's new?
See Fortran 1.1 - Release Notes.
Description
This extension provides support for applications written using Fortran languages. 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.
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 CAST analyzers.
Technology support
| 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. |
| Release | Operating System | Supported |
|---|---|---|
| 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 (In Fortran have .h files are use 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 |
Fortran 90 | *.f90 |
Fortran 77 | *.f77 |
Download and installation instructions
The extension will be automatically installed by CAST Imaging Console 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 in CAST Imaging Console.
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
