6.2.0

See also

• The full Changelog.

Summary

• Added a new option escape_solidus to specify if the forward slash ("/") is to be escaped when serializing JSON. By default, it is no longer escaped (this changes the behavior introduced in 6.0.0)
• Allow the unit tests to be run from within the Visual Studio solution
• Compiling now works for the CMake-produced Visual Studio solution on Windows (note that the CMake-produced solution is a bit different from the other one provided).
• Fixed an issue causing a problem with the NAG compiler.

6.1.0

See also

• The full Changelog.

Summary

• Added an optional allow_duplicate_keys argument to the various initialize routines. This is True by default. If False, then duplicate keys are considered an error. Also added check_for_duplicate_keys and check_children_for_duplicate_keys methods that can be called.
• Added support for JSONPath "bracket-notation" mode for specifying paths to JSON variables.
• Replaced CMAKE_INSTALL_LIBDIR with INSTALL_LIB_DIR in the CMake project.
• Fixed bug in the lowercase_string routine that could cause a crash for Debug builds.

6.0.0

See also

• The full Changelog.

Summary

• Added a routine (json_value_reverse) to reverse an array or object.
• Fixed a bug where using no_whitespace mode could still print line breaks in some cases.
• Strings (name key and value) were not being properly escaped/unescaped in some contexts. This change introduces a small backward incompatibility (formerly, if keys contained escape characters, the user would have to include them when getting their value). Now, the string variables in all user-facing API calls are unescaped (i.e., the user does not have to manually escape the keys to get their associated value). All strings are also now properly returned unescaped, no matter how the JSON structure was constructed. Escaping is now done in all cases if necessary when the JSON is printed to a string, file or the console.

5.3.0

See also:

• The full Changelog.

Summary:

• It is now possible to build a JSON structure by specifying the paths to the variables. The update routines also now use this new feature so if the variable is not present, it will be added using the path (formerly, it added it as a name, which was inconsistent). Renamed the argument to the update routines from name to path.
• Added new get routine to return an allocatable string array
• Arrays of scalar values can now optionally be printed on a single line
• When reading an empty JSON array it is now returned as an allocated array with zero length (rather than an unallocated array).
• Fixed an issue where the char_count wasn’t always correct, which caused the error message for invalid JSON to be wrong.
• Fixed an issue where values with significant trailing whitespace were being trimmed when printed.
• Fixed two bugs in json_get_path for RFC 6091 path mode. Special characters weren’t being encoded properly, and it didn't work if the final key was all whitespace.
• Fixed an issue with indenting of arrays within arrays.

5.2.0

See also:

• The full Changelog.

Summary:

• Added support for comments in JSON files.
• Added support for RFC 6901 paths.
• Can now specify default real and integer kinds using compiler directives.
• compact_reals and real_format='*' can now be used at the same time.
• Added option to change default path separator character.
• Add pkg-config file
• Real numbers now written with 17 digits of precision (previously it was using 16 which doesn't accurately represent all values to full precision)

5.1.0

See also:

• The full Changelog.

Summary:

• Added a traverse routine to json_file
• Added get and set routines for the json_core in a json_file
• Added get_path routine for returning the path of a json_value variable in a linked list
• Added option (unescape_strings) for specifying if strings are to be returned in their escaped or unescaped form.
• When strict_type_checking is False, the get routines will now return integer, double, logical, and null values as strings.
• Added insert_after routine
• Move json type integer variables into the json_parameters module
• Added option (no_whitespace) to print JSON without extra whitespace
• Added new info routines (json_info_by_path, json_matrix_info_by_path, and json_matrix_info)
• Added an API for adding Null variables
• Fixed doc deployment problems

5.0.2

Minor documentation fix.

5.0.1

No changes to the library, just the build system and documentation.

• Now works with latest version of FORD.
• FORD now uses the Intel preprocessor when library is built with the Intel compiler (and gfortran when compiled with gfortran).
• Color documentation graph edges and add build date for FORD documentation
• ShellCheck script files.

5.0.0

See also:

• this Wiki page on how to update your code to be compatible with this release.
• The full Changelog.

Summary:

• The library is now thread safe.
• Split json_module into multiple files.
• Added new initialize(), failed(), print_error_message(), check_to_errors(), and clear_exceptions() to the json_file class.
• The number of spaces for indenting can now be user specified.
• Updates for Visual Studio project .
• Added a validate() method for validating JSON linked lists.
• Added some additional error checks for malformed JSON linked lists.
• Added a new routine is_child_of to check if one json_value is a descendant of another.
• Added new options for case-insensitive searching of names/paths, as well as the option to consider trailing space significant.
• Added a routine to enable swapping of elements in a json_value linked list.
• Rename parameters RK, IK, LK, CK, and CDK using less generic names (json_RK, json_IK, json_LK, json_CK, and json_CDK).
• Calling the initialize() method (which is now in json_core and json_file) is no longer mandatory.
• Added a rename() method for renaming a json_value variable.
• Added some compiler directives so that workarounds for Gfortran bugs are not used for other compilers.
• Added option for strict typing for get routines.
• Various cosmetic changes and renaming of some of the dummy arguments in some procedures.
• Added checks to avoid unnecessary looping when traversing arrays if an exception is thrown.
• Added a new get_child method to get the first child.
