Arguments

Type IntentOptional Attributes Name
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=*), intent(in), optional :: comment_char

If present, these characters are 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:

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_keys Read more…
logical(kind=LK), intent(in), optional :: escape_solidus

Note that this option does not affect parsing (both escaped and unescaped are still valid in all cases).

logical(kind=LK), intent(in), optional :: stop_on_error

If an exception is raised, then immediately quit. (Default is False).
integer(kind=IK), intent(in), optional :: null_to_real_mode

if strict_type_checking=false:

integer(kind=IK), intent(in), optional :: non_normal_mode

How to serialize NaN, Infinity, and -Infinity real values:

logical(kind=LK), intent(in), optional :: strict_integer_type_checking

logical(kind=LK), intent(in), optional :: allow_trailing_comma

Allow a single trailing comma in arrays and objects. (default is true)
