initialize_json_core_in_file Subroutine

private subroutine initialize_json_core_in_file(me, verbose, compact_reals, print_signs, real_format, spaces_per_tab, strict_type_checking, trailing_spaces_significant, case_sensitive_keys, no_whitespace, unescape_strings, comment_char, path_mode, path_separator, compress_vectors, allow_duplicate_keys, escape_solidus, stop_on_error, null_to_real_mode, non_normal_mode, use_quiet_nan, strict_integer_type_checking)

Initialize the json_core for this json_file. This is just a wrapper for json_initialize.

Note

This does not destroy the data in the file.

Type Bound

json_file

Arguments

Type IntentOptional Attributes Name
class(json_file), intent(inout) :: me
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
  • If True [default] then no special checks are done to check for duplicate keys.
  • If False, then after parsing, if any duplicate keys are found, an error is thrown. A call to json_value_validate will also check for duplicates.
logical(kind=LK), intent(in), optional :: escape_solidus
  • If True then the solidus “/” is always escaped “\/” when serializing JSON
  • If False [default], then it is not escaped.

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:

  • 1 : an exception will be raised if try to retrieve a null as a real.
  • 2 : a null retrieved as a real will return a NaN. [default]
  • 3 : a null retrieved as a real will return 0.0.
integer(kind=IK), intent(in), optional :: non_normal_mode

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

  • 1 : as strings (e.g., “NaN”, “Infinity”, “-Infinity”) [default]
  • 2 : as JSON null values
logical(kind=LK), intent(in), optional :: use_quiet_nan
  • If true [default], null_to_real_mode=2 and string_to_real will use ieee_quiet_nan for NaN values.
  • If false, ieee_signaling_nan will be used.
logical(kind=LK), intent(in), optional :: strict_integer_type_checking
  • If false, when parsing JSON, if an integer numeric value cannot be converted to an integer (integer(IK)), then an attempt is then make to convert it to a real (real(RK)).
  • If true, an exception will be raised if the integer value cannot be read.

(default is true)
