json_kinds Module

JSON-Fortran kind definitions.

License

  • JSON-Fortran is released under a BSD-style license. See the LICENSE file for details.

    When present, Unicode support is enabled. Note that this is currently only supported with the gfortran compiler. Example: gfortran -DUSE_UCS4 ... The documentation given here assumes USE_UCS4 is defined.

     character kind respectively. Client code **MUST** ensure characters of ```kind=CK```
 are used for all character variables and strings passed to the JSON-Fortran
 library *EXCEPT* for file names which must be of ```'DEFAULT'``` character kind,
 provided here as ```CDK```. In particular, any variable that is a: json path, string
 value or object name passed to the JSON-Fortran library **MUST** be of type ```CK```.

    JSON-Fortran procedures since they have been overloaded to accept intent(in) character arguments of the default (CDK) kind. If you find a procedure which does not accept an intent(in) literal string argument of default kind, please file an issue on GitHub.

    changed using optional preprocessor flags. This library was built with kinds: real(kind=real64) [8 bytes] and integer(kind=int32) [4 bytes] .

    the real kinds with less precision are also provided in the library, but all are converted to real(RK) variables internally.

Variables

Type Visibility Attributes Name Initial
integer, public, parameter :: CDK = selected_char_kind('DEFAULT')

Processor dependent ‘DEFAULT’ character kind. This is 1 byte for the Intel and Gfortran compilers.
integer, public, parameter :: CK = selected_char_kind(json_fortran_string_kind)

Default character kind used by JSON-Fortran. If ISO 10646 (UCS4) support is available, use that, otherwise, gracefully fall back on ‘DEFAULT’ characters. Currently only gfortran >= 4.9.2 will correctly support UCS4 which is stored in 4 bytes. (and perhaps others).
integer, public, parameter :: IK = int32

Default integer kind if not specified [4 bytes]
integer, public, parameter :: LK = logical_kinds(min(3, size(logical_kinds)))

Default logical kind. This is 4 bytes for the Intel and Gfortran compilers (and perhaps others). The declaration ensures a valid kind if the compiler doesn’t have a logical_kinds(3).
integer, public, parameter :: RK = real64

Default real kind if not specified [8 bytes]
character(kind=CDK, len=*), private, parameter :: json_fortran_string_kind = 'ISO_10646'

String kind preprocessor macro. gfortran compiler AND UCS4 support requested:
