public interface json_file

Structure constructor to initialize a json_file object with an existing json_value object, and either the json_core settings or a json_core instance.

Example

 ...
 type(json_file)  :: my_file
 type(json_value),pointer :: json_object
 type(json_core) :: json_core_object
 ...
 ! Construct a json_object:
 !could do this:
   my_file = json_file(json_object)
 !or:
   my_file = json_file(json_object,verbose=.true.)
 !or:
   my_file = json_file(json_object,json_core_object)

Cast a json_value object as a json_file object. It also calls the initialize() method.

Arguments

Type IntentOptional AttributesName
type(json_value), intent(in), optional pointer:: p

json_value object to cast as a json_file object
logical(kind=LK), intent(in), optional :: verbose

mainly useful for debugging (default is false)
logical(kind=LK), intent(in), optional :: compact_reals

to compact the real number strings for output (default is true)
logical(kind=LK), intent(in), optional :: print_signs

always print numeric sign (default is false)
character(kind=CDK,len=*), intent(in), optional :: real_format

Real number format: 'E' [default], '*', 'G', 'EN', or 'ES'
integer(kind=IK), intent(in), optional :: spaces_per_tab

number of spaces per tab for indenting (default is 2)
logical(kind=LK), intent(in), optional :: strict_type_checking

if true, no integer, double, or logical type conversions are done for the get routines (default is false)
logical(kind=LK), intent(in), optional :: trailing_spaces_significant

for name and path comparisons, is trailing space to be considered significant. (default is false)
logical(kind=LK), intent(in), optional :: case_sensitive_keys

for name and path comparisons, are they case sensitive. (default is true)
logical(kind=LK), intent(in), optional :: no_whitespace

if true, printing the JSON structure is done without adding any non-significant spaces or linebreaks (default is false)
logical(kind=LK), intent(in), optional :: unescape_strings

If false, then the raw escaped string is returned from json_get_string and similar routines. If true [default], then the string is returned unescaped.
character(kind=CK,len=1), intent(in), optional :: comment_char

If present, this character is used to denote comments in the JSON file, which will be ignored if present. Example: ! or #. Setting this to a blank string disables the ignoring of comments. (Default is !).
integer(kind=IK), intent(in), optional :: path_mode

How the path strings are interpreted in the get_by_path routines: * 1 – Default mode (see json_get_by_path_default) * 2 – as RFC 6901 "JSON Pointer" paths (see json_get_by_path_rfc6901) * 3 – JSONPath "bracket-notation" see json_get_by_path_jsonpath_bracket)
character(kind=CK,len=1), intent(in), optional :: path_separator

The path separator to use in the "default" mode for the paths in the various get_by_path routines. Example: . [default] or %. Note: if path_mode/=1 then this is ignored.
logical(kind=LK), intent(in), optional :: compress_vectors

If true, then arrays of integers, nulls, doubles, and logicals are printed all on one line. [Note: no_whitespace will override this option if necessary]. (Default is False).
logical(kind=LK), intent(in), optional :: allow_duplicate_keysRead more…
logical(kind=LK), intent(in), optional :: escape_solidusRead more…
logical(kind=LK), intent(in), optional :: stop_on_error

If an exception is raised, then immediately quit. (Default is False).
