Fortran-Lint

Software Development Powerfully Simplified

Features

Whole program analysis! A step beyond compilers to assess your program in its entirety
A true parser, not a scanner rummaging through text
Analyze the file(s) you're currently working on in the context of the entire program, dramatically reducing results to review
Quickly find hundreds of problems your compiler can't
Isolate problems in minutes that can take days using a runtime debugger
Powerful static source analyzer with 1662 code checks
Search and destroy security holes
- One Definition Rule (ODR) violations
Comprehensive cross reference including COMMON blocks for refactoring or converting from serial to parallel code
View subprogram v(G) complexity, line count, and argument count to help target refactoring efforts
Call Tree for fast code familiarization

Three interface options fit the way you code
- Easy to operate Cleanscape GUI provides point-and-click control and reports hyper- linked to sources via your favorite code editor
- Command line mode with return codes for script and/or build operations
- Integration with Visual Studio and Eclipse both extracts project settings and hyperlinks reports directly in the IDE's output window
OpenMP analysis
Library interface files for MPI, OpenMP, and NetCDF with set/ reference information for 100% thorough analysis
The most in hosts (Windows, Linux, Mac, Unix, VMS) and flexible licensing options
Get- and keep-your project on track

Benefits

Software Development, Powerfully Simplified

In this era of large, complex Fortran code – often using OpenMP and/or MPI, often collaborative between industry, government, and educational institutions – you need fast, flexible, yet powerful analysis to help produce code that is bug-free, runs as expected for all inputs, and is free from weaknesses to security threats.

Cleanscape Fortran Lint (Flint) is a static source code analyzer that automatically identifies problems at their source, prior to compiling or executing. From its first use, this tool can save you hours and hours of tedious debugging, and greatly reduces the resources required for testing – both development and integration phases.

Flint rigorously examines source files both individually and as a project, almost instantly generating comprehensive and meaningful reports on problems often overlooked by Fortran compilers.

GUI: All reports depict hyperlinks in red; clicking a hyperlink opens the source file at the line number associated with the analysis message in the user's specified code editor

Supported Environments

ANSI Fortran standards from pre-Fortran 77 to Fortran 2008
Library shell files included to provide 100% thorough interface analysis for
- MPI
