A KISS tool for automatic building modern Fortran projects.
GNU Make, CMake, SCons & Co. are fantastic tools, even too much for poor-fortran-people.
However, the support for modern Fortran project is still poor: in particular, it is quite difficult (and boring) to track the inter-module-dependency hierarchy of project using many module files.
Modern Fortran programs can take great advantage of using modules (e.g. encapsulation), however their compilations can quickly become a nightmare as the number of modules grows. As a consequence, an automatic build system able to track (on the fly) any changes on the inter-module-dependency hierarchy can save the life of poor-fortran-people.
There are a lot of alternatives for deal with inter-module-dependency hierarchy, but they can be viewed as a pre-processor for the actual building system (such as auto-make tools or even the Fortran compiler itself that, in most cases, can generate a dependency list of a processed file), thus they introduce another level of complexity... but poor-fortran-people always love the KISS (Keep It Simple, Stupid) things!
Let us consider the following project tree
└── src ├── cumbersome.f90 └── nested-1 ├── first_dep.f90 └── nested-2 └── second_dep.inc
The main program contained into
cumbersome.f90 depends on
first_dep.f90 via the use statement
use NesteD_1, thus it actually depends on the module
nested_1. This module depends on
second_dep.inc via the include statement
include 'second_dep.inc'. Note that the dependency files are stored in a cumbersome nested tree. Write a makefile for this very simple example could waste many minutes... when the modules number increases the time wasted blows up!
It would be very nice to have a tool that automatically track the actual dependency-hierarchy and build the project on the fly, without the necessity to track the dependency-hierarchy changes. FoBiS.py just makes this... and few more things!
Suppose your goal is to build some (all) of the main programs contained into the project tree. In this case FoBiS.py can save your life: just type
in the root of your project and FoBis.py will build all the main programs nested into the current root directory. Obviously, FoBiS.py will not (re-)compile unnecessary objects if they are up-to-date (like the "magic" of a makefile).
FoBiS.py has many (ok... some) others interesting features: if I have convinced you, please read the following.
