What is it?

findent indents/beautifies/converts and can optionally generate the dependencies of Fortran sources.

Features

• Supports Fortran-66 up to Fortran-2018
• Converts from Fixed Form to Free Form and vice-versa
• Honours cpp and coco preprocess statements
• Honours OpenMP conditionals
• Validated against all constructs in 'Modern Fortran explained, Incorporating Fortran 2018, Metcalf e.a.'
• Supported platformrs: Unix and Windows
• High speed: 50K - 100K lines per second
• vim, gedit, emacs: findent optionally emits configuration files for these editors to use findent as a plugin.

Installation

Normal installation using pip

pip install findent

Supported platforms

OS	Architecture
Linux	x64, arm64, i686, aarch64, ppc64, s390x
MacOS	x64, arm64
Windows	x64

Examples

Format file in.f90 to out.f90

findent < in.f90 > out.f90

Format with 4-space indentation and convert Fixed Form in.f to Free Form out.f90

findent -i4 -ofree < in.f > out.f90

Format and refactor all files with .f extension in the current directory

wfindent -i4 -Rr *.f

Generating Fortran source dependencies for use in Makefile

findent will generate a dependency list for:

• definitions and uses of modules and submodules
• include, #include and ??include statements

In your Makefile add something similar to:

findent --makefdeps > makefdeps
chmod +x makefdeps

include deps
dep deps:
  ./makefdeps *.f90 > deps

The flag --makefdeps generates a script in the standard output. Depending on your usecase the script might not suffice and you will need to write your own version.
