A linter for Fortran files
# Fortran syntax checker
There are 2 ways of installing the linter. The recommended one is through pip
pip install fortran-linter
The other way is to clone this repository and install it from the local copy:
git clone https://github.com/cphyc/fortran-syntax.git pip install .
Please note that depending on your installation, you may have to add sudo to the pip install line. This is due to the fact that the package is shipped with a script fortran-linter. For some installation, the creation of this file may require root access.
This tool checks for fortran syntax against a few rules. To print a list of all the warnings for a file, run:
fortran-linter myfile.f90 –syntax-only
To try to fix the warnings in place, do:
fortran-linter myfile.f90 -i
The original file will be backuped into myfile.f90.orig. All the safe fixes will be done and stored in the file myfile.f90.
For more help, you can type
- Currently, the following things are checked:
- Ponctuation should be followed by a space, this include ,, ; and )..
- The following special characters are surrounded by at least one space: ::, =.
- A line should not exceed 120 characters (this is somehow already extreme).
- One should use use mpi instead of include “mpif.h”. Note that this is not fixed by default as it may break codes where include “mpif.h” follows and implicit none statement.
- Spaces are preferred over tabs, trailing whitespaces are cleaned.
- Warnings are raised if you use real(8) :: foo. One should rather use integer, parameter :: dp=selected_real_kind(15); real(dp) :: foo or use iso_fortran_env; real(real64) :: foo
