FORTRAN CodeCleaner and Linter

Cleans archaic Fortran code.

Installation and Simple Use Case.

Features:

• Convert fixed form code to free form code
• Tab -> Space conversion
• Add spaces around/behind operators and typical structures
• Strip trailing whitespace
• Easily pluggable (vim-plugin inside)

Planned Features:

• Lint using gfortran as backend

Installation:

Assuming, you cloned the repo into your location of choice via:

git clone https://github.com/rscircus/fortress
cd fortress

On your local machine, this should work:

python setup.py install

Working on a cluster or remote without any rights, a more fine grained approach:

python setup.py install --user

If you want to deinstall FORTRESS later on, you can use

python setup.py install --user --record install.txt

instead. All installed files are documented in install.txt then.

Furthermore the installation dir should be added to PATH. I.e.:

export PATH=$PATH:~/.local/bin

Usage:

> fortress -h
usage: fortress [-h] [-v] [-d | -i] [-r | -l START-END] [-e PATTERN]
                [-s STYLE] [--strict] [-t]
                [files [files ...]]

FORTRESS is a formatter/modernizer of legacy FORTRAN code.

  -i, --in-place        make changes to files in place
  -r, --recursive       run recursively over dirs
  -l START-END, --lines START-END
                        range of lines to reformat; 1-based
  -e PATTERN, --exclude PATTERN
                        patterns for files to exclude from formatting
  -s STYLE, --style STYLE
                        specify formatting style via local style.ini
