# fprettify [](https://github.com/pseewald/fprettify/actions/workflows/test.yml) [](https://coveralls.io/github/pseewald/fprettify?branch=master)   [](https://codeclimate.com/github/pseewald/fprettify) fprettify is an auto-formatter for modern Fortran code that imposes strict whitespace formatting, written in Python. **NOTE:** I'm looking for help to maintain this repository, see [#127](https://github.com/pseewald/fprettify/issues/127). ## Features - Auto-indentation. - Line continuations are aligned with the previous opening delimiter `(`, `[` or `(/` or with an assignment operator `=` or `=>`. If none of the above is present, a default hanging indent is applied. - Consistent amount of whitespace around operators and delimiters. - Removal of extraneous whitespace and consecutive blank lines. - Change letter case (upper case / lower case conventions) of intrinsics - Tested for editor integration. - By default, fprettify causes whitespace changes only and thus preserves revision history. - fprettify can handle cpp and [fypp](https://github.com/aradi/fypp) preprocessor directives. ## Limitations - Works only for modern Fortran (Fortran 90 upwards). - Feature missing? Please create an issue. ## Requirements - Python 3 (Python 2.7 no longer supported) - [ConfigArgParse](https://pypi.org/project/ConfigArgParse): optional, enables use of config file ## Examples Compare `examples/*before.f90` (original Fortran files) with `examples/*after.f90` (reformatted Fortran files) to see what fprettify does. A quick demonstration: ```Fortran program demo integer :: endif,if,elseif integer,DIMENSION(2) :: function endif=3;if=2 if(endif==2)then endif=5 elseif=if+4*(endif+& 2**10) elseif(endif==3)then function(if)=endif/elseif print*,endif endif end program ``` ⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩ `fprettify` ⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩ ```Fortran program demo integer :: endif, if, elseif integer, DIMENSION(2) :: function endif = 3; if = 2 if (endif == 2) then endif = 5 elseif = if + 4*(endif + & 2**10) elseif (endif == 3) then function(if) = endif/elseif print *, endif endif end program ``` ## Installation The latest release can be installed using pip: ```sh pip install --upgrade fprettify ``` Installation from source requires Python Setuptools: ```sh pip install . ``` For local installation, use `--user` option. If you use the [Conda](https://docs.conda.io/) package manager, fprettify is available from the [conda-forge](https://conda-forge.org/) channel: ```sh conda install -c conda-forge fprettify ``` ## Command line tool Autoformat file1, file2, ... inplace by ```sh fprettify file1, file2, ... ``` The default indent is 3. If you prefer something else, use `--indent n` argument. In order to apply fprettify recursively to an entire Fortran project instead of a single file, use the `-r` option. For more options, read ```sh fprettify -h ``` ## Editor integration For editor integration, use ```sh fprettify --silent ``` For instance, with Vim, use fprettify with `gq` by putting the following commands in your `.vimrc`: ```vim autocmd Filetype fortran setlocal formatprg=fprettify\ --silent ``` ## Deactivation and manual formatting (experimental feature) fprettify can be deactivated for selected lines: a single line followed by an inline comment starting with `!&` is not auto-formatted and consecutive lines that are enclosed between two comment lines `!&<` and `!&>` are not auto-formatted. This is useful for cases where manual alignment is preferred over auto-formatting. Furthermore, deactivation is necessary when non-standard Fortran syntax (such as advanced usage of preprocessor directives) prevents proper formatting. As an example, consider the following snippet of fprettify formatted code: ```fortran A = [-1, 10, 0, & 0, 1000, 0, & 0, -1, 1] ``` In order to manually align the columns, fprettify needs to be deactivated by ```fortran A = [-1, 10, 0, & !& 0, 1000, 0, & !& 0, -1, 1] !& ``` or, equivalently by ```fortran !&< A = [-1, 10, 0, & 0, 1000, 0, & 0, -1, 1] !&> ``` ## Contributing / Testing The testing mechanism allows you to easily test fprettify with any Fortran project of your choice. Simply clone or copy your entire project into `fortran_tests/before` and run `python setup.py test`. The directory `fortran_tests/after` contains the test output (reformatted Fortran files). If testing fails, please submit an issue!
