Fortran - 1.0
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 | ✅ |
Transactions
Transaction support is derived from metamodel concepts used to build CAST Imaging Blueprint and structural transaction flows. Entry Points start transactions; Exit Points include both output/boundary concepts and Data Entities manipulated by transactions.
| Role | Support | Breakdown |
|---|---|---|
| Entry Point | No direct concept type details | |
| Exit Point | No direct concept type details |
Data version: 1.0.2
ISO 5055 Structural Rules
Quality support is based on ISO 5055 structural rules available for the selected extension version.
| Reliability | Maintainability | Security | Performance Efficiency |
|---|---|---|---|
Data version: 1.0.2
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(.hfiles are used as include files, however for the most part,*.incare 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
