What is FiNeR?

Modern Fortran standards (2003+) have introduced better support for strings manipulations. Exploiting such new Fortran capabilities, FiNeR provides an easy to use module library for input (parsing) and output (generating) INI (config) files.

Documentation

Besides this README file the FiNeR documentation is contained into its own wiki. Detailed documentation of the API is contained into the GitHub Pages that can also be created locally by means of ford tool.

A Taste of FiNeR

Let us assume our goal is to parse a config file. It is as simple as

use finer
...
type(file_ini)                :: fini     !< INI file handler.
character(len=:), allocatable :: source   ! Testing string.
real(R4P), allocatable        :: array(:) ! Array option.
integer(I4P)                  :: error    ! Error code.
...
source='[section-1]'//new_line('A')//    &
       'option-1 = one'//new_line('A')// &
       'option-2 = 2.'//new_line('A')//  &
       '           3.'//new_line('A')//  &
       'option-3 = bar'//new_line('A')// &
       '[section-2]'//new_line('A')//    &
       'option-1 = foo'
call fini%load(source=source)
allocate(array(1:fini%count_values(section='section-1',option='option-2')))
call fini%get(section='section-1',option='option-2',val=array,error=error)
if (error==0) then
  print*,array
else
  ! errors occur...
endif

And what about the generation of an INI file? It is simple as parsing an old one:

use finer
...
type(file_ini) :: fini !< INI file handler.
...
call fini%add(section='sec-foo')
call fini%add(section='sec-foo',option='bar',val=-32.1_R8P)
call fini%add(section='sec-foo',option='baz',val=' hello FiNeR! ')
call fini%add(section='sec-foo',option='array',val=[1,2,3,4])
call fini%add(section='sec-bar')
call fini%add(section='sec-bar',option='bools',val=[.true.,.false.,.false.])
call fini%save(filename='foo.ini')

A file named foo.ini is created. It contains something like:

[sec-foo]
bar = -0.321000000000000E+002
baz =  hello FiNeR!
array = +1 +2 +3 +4
[sec-bar]
bools = T F F
