Complete Changeset

9.0.1 (2024-06-11)

Complete Changeset or Download v9.0.1

Enhancements:

  • No code changes. Just an update to the CI to fix documentation deployment. #573 (jacobwilliams)

9.0.0 (2024-06-11)

Complete Changeset or Download v9.0.0

Enhancements:

  • By default, the JSON pointer in json_file is now destroyed before loading. This is to prevent a memory leak if the type is used later to load another file. #561 #562 (jacobwilliams) Also added a new option destroy_pointer to the json_file load routines, which can be set to False to get the old behavior (not to destroy it). #561 #562 (jacobwilliams)
  • Added add a new nullify_pointer option to the json_file constructor (default is True) (jacobwilliams) #564 #566
  • Updates for the CI and unit tests. Now testing with FPM, and running all tests with valgrind to check for memory leaks. #563 #565 #568 (jacobwilliams)
  • Added an optional allow_trailing_comma argument to the initialize routines (default is True). If set to False, this disallows extra trailing commas in arrays and objects. #569 #570 (jacobwilliams)

8.5.2 (2024-05-27)

Complete Changeset or Download v8.5.2

Bug Fixes:

  • Fixed a CMake bug where the package version was not set correctly, which caused the CMake configuration files to be saved to a folder with blank version name. #560 (timfelle)

8.5.1 (2024-05-26)

Complete Changeset or Download v8.5.1

Bug Fixes:

8.5.0 (2024-05-25)

Complete Changeset or Download v8.5.0

Enhancements:

  • Various CMake updates:
    • Only installing if json-fortran is the top level project. Added a library alias so that json fortran can be included with find_package, fetch_content, and add_subdirectory easily. #526 #527 , #528, #529 #556 (K20shores)
    • Fixed compilation with Ninja and Intel OneAPI ifx compiler, and added some CMake options #557 (lmdiazangulo)

Bug fixes:

8.0.0 (2020-04-04)

Complete Changeset or Download v8.0.0

Enhancements:

  • Cleanup of the API for reading and writing JSON. The main methods are now called print, load, serialize and deserialize. Note that the previous ones are still present for backward compatibility. #397 #409 (jacobwilliams)
  • Added a finalizer to the json_file type #199 #406 (jacobwilliams)
  • Added new optional arguments (null_to_real_mode, non_normal_mode, use_quiet_nan) to the initialize routines to handle NaN and Infinity. #395
  • Added a new optional argument (strict_integer_type_checking) to the initialize routines. If enabled, when parsing an integer value, if the parsing fails (e.g., the integer is outside the range of the integer kind), it will then attempt to convert it to a real. #444 #446 (jacobwilliams)
  • json_info will now check for exceptions and raise one if the pointer is not associated #424 #425 (jacobwilliams)
  • Allow the parser to work with some nonstandard real value representations (leading +, no leading digit before decimal, D/d format). #417 #418 (jacobwilliams)
  • Added a character string to json_file assignment operator #410 #411 (jacobwilliams)
  • Added a json_print_to_console method to json_core to match the one in json_file #408

Bug fixes:

  • Fixed a crash in json_file_check_for_errors if the error_msg was not present. #420
  • Fixed a potential issue with real to integer conversion when the library is compiled with a non-default integer kind. #449 #450 (jacobwilliams)
  • Fixed a dangling pointer in unit test 10. #422 #423 (jacobwilliams)

CMake updates:

  • Updated CMake to enable building JSON-Fortran as a subdirectory of another project #445 #443 (rouson)
  • Updated CMake for compatibility with older versions < 3.7. #442 #451 jacobwilliams)
  • Allow linking to JSON-Fortran from GFortran programs using OpenCoarrays as the coarray runtime implementation. Use the -DJSON_FORTRAN_USE_OpenCoarrays:BOOL=ON option to CMake to enable this. (NOTE: The fact that this is required may be a bug in GFortran.)

CI updates:

7.1.0 (2019-06-23)

Complete Changeset or Download v7.1.0

Enhancements:

Bug fixes:

  • Fix for undeclared variable causing failing test on Mac #392 (porteri)
  • Fixed a bug where using json%add() to create new variables in a structure would stop the program if stop_on_failure was enabled. #403 #404 (jacobwilliams)

7.0.0 (2019-01-26)

Complete Changeset or Download v7.0.0

Enhancements:

  • Added support for multiple real kinds:
    • The library now supports the default real kind specified (real32, real64 and real128) as well as the kinds in this set with less precision than the default. For example, if real64 is specified (which is the default), then both real32 and real64 are available in all the public APIs. Internally, the values are always stored in a variable of the default kind. #386 #387 (jacobwilliams)
    • Added a create_real() method and a json_real parameter to replace create_double() and json_double. The old versions are still available for backward compatibility.
    • Added CMake options to control integer and real kinds #284
    • Updated the default real format statement to correctly correspond to the specified real kind.
  • Added new json_file constructor functions for strings. This allows a json_file to be initialized using syntax such as: f = json_file('{"x": 1}'). #381 #382 (jacobwilliams)
  • Fixed some links in the documentation.

Bug fixes:

  • Fixed an issue where the parser would fail if the JSON structure was just a lone integer. #388 #389 (jacobwilliams)
  • Fixed an issue where the unit tests did not compile when using real32 or real128. #383 #384 (jacobwilliams)
  • Fixed various issues preventing compilation if the integer kind was changed from the default. #365 #385 (jacobwilliams)
  • Renamed the integrated tests preprocessor flag to INTEGRATED_TESTS since it was mispelled. #390 #391 (jacobwilliams)

  • Various updates to error message reporting.
    • The two arguments to json_file_check_for_errors() are now optional to match the core routine. #356
    • Some adjustments to error messages for invalid hex strings. Validation of hex strings is now done in the unescape_string() routine. #354
    • A string that ends in an escape character \ is now flagged as invalid. #353

Fixed bugs:

  • Fixed a bug in the annotate_invalid_json() routine. #355

  • Added missing arguments (trim_str and adjustl_str) to some of the string wrapper routines. #347 #348 (jacobwilliams)
  • Various minor changes to remove some compiler warnings and a line length standards violation.
  • Various documentation string updates.

Fixed bugs:

  • Fixed a dangling pointer bug in the destroy method that was causing unpredictable behavior in this routine which could cause a crash for some compilers #307 #350 (jacobwilliams)

6.7.0 (2018-07-10)

Complete Changeset or Download v6.7.0

Enhancements:

  • Made the two arguments to json_check_for_errors() optional, so now either or both can be used. Note that if no error has been raised, then error_msg is now returned unallocated. #344 #345 (jacobwilliams)
  • Added an additional error check in json_value_print() to check for an unassociated pointer. #342 #343 (jacobwilliams)
  • Added remove() method to json_file #339 #340 (jacobwilliams)
  • Added additional error checks to json_value_add_member(). Now it will raise an exception if try to add a child to a non-array or non-object. #337 #338 (jacobwilliams)
  • Added some additional unit tests to increase coverage #336 (jacobwilliams)

Fixed bugs:

  • Fixed a bug in json_value_clone_func() where it could crash if attempting to clone an array element. Updated this routine to improve behavior when cloning an array element (the subsequent entries are no longer cloned). #334 #335 (jacobwilliams)

6.6.0 (2018-07-01)

Complete Changeset or Download v6.6.0

Enhancements #332 (jacobwilliams)

  • Now, attempting to get a string variable as an integer, double, or logical will attempt to convert it to a string if strict_type_checking=False. Formerly these cases would raise an exception. #331
  • Fixed an inconsistency in json_get_by_path(). Now if using the optional found argument, any exceptions raised by this routine are cleared. #330
  • Changed the name argument in json_value_remove_if_present() to 'path' to be consistent with other routines since it is really a path. #329
  • Various documentation string updates.

Fixed bugs:

  • Fixed a bug in wrap_json_get_path() where an optional argument was being used without checking if it was present. #333

6.5.0 (2018-06-23)

Fixed issues:

  • Fixed a bug in the escaping logic where / characters in strings would not be printed under some circumstances. This bug was introduced in the 6.2.0 release. #312 (jacobwilliams)

6.2.0 (2018-03-10)

Complete Changeset or Download v6.2.0

Enhancements:

  • Allow the unit tests to be run from within the Visual Studio solution #295 (Hugh-walsh, jacobwilliams)
  • 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). #70 #309 (handrake0724, jacobwilliams)
  • 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) #304 #305 (jacobwilliams)

Fixed issues:

6.1.0 (2017-11-05)

Complete Changeset or Download v6.1.0

Enhancements:

  • 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. #250 #290 (jacobwilliams)
  • Added support for JSONPath "bracket-notation" mode for specifying paths to JSON variables. #266 #292 (jacobwilliams)

Fixed issues:

  • Replaced CMAKE_INSTALL_LIBDIR with INSTALL_LIB_DIR in the CMake project. #286 (foeroyingur)
  • Fixed bug in the lowercase_string routine that could cause a crash for Debug builds. #293 #294 (jacobwilliams)

6.0.0 (2017-08-24)

Complete Changeset or Download v6.0.0

Enhancements:

Fixed issues:

  • Fixed a bug where using no_whitespace mode could still print line breaks in some cases #288 (jacobwilliams)
  • 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. #287 #289 (jacobwilliams)

5.3.0 (2017-04-07)

Complete Changeset or Download v5.3.0

Enhancements:

  • 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. #257 #261 #268 #270 (jacobwilliams)
  • Added new get routine to return an allocatable string array #245 #265 (jacobwilliams)
  • Arrays of scalar values can now optionally be printed on a single line #228 #273 (jacobwilliams)
  • When reading an empty JSON array it is now returned as an allocated array with zero length (rather than an unallocated array). #276 #277 (jacobwilliams)

Fixed issues:

  • Fixed an issue where the char_count wasn’t always correct, which caused the error message for invalid JSON to be wrong. #272 #274 (jacobwilliams)
  • Fixed an issue where values with significant trailing whitespace were being trimmed when printed. #263 (jacobwilliams)
  • 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. #262 #264 (jacobwilliams)
  • Fixed an issue with indenting of arrays within arrays. #269 #271 (jacobwilliams)

5.2.0 (2017-03-05)

Complete Changeset or Download v5.2.0

Enhancements:

Fixed issues:

  • Real numbers now written with 17 digits of precision (previously it was using 16 which doesn't accurately represent all values to full precision) #230 #241 (jacobwilliams) #232 (jacobwilliams)
