json_get_by_path_rfc6901 Subroutine

private subroutine json_get_by_path_rfc6901(json, me, path, p, found)

Returns the json_value pointer given the path string, using the “JSON Pointer” path specification defined by RFC 6901.

Note that trailing whitespace significance and case sensitivity are user-specified. To fully conform to the RFC 6901 standard, should probably set (via initialize):

  • case_sensitive_keys = .true. [this is the default setting]
  • trailing_spaces_significant = .true. [this is not the default setting]
  • allow_duplicate_keys = .false. [this is not the default setting]

Example

    type(json_core) :: json
    type(json_value),pointer :: dat,p
    logical :: found
    !...
    call json%initialize(path_mode=2)
    call json%get(dat,'/data/2/version',p,found)

Reference

Note

Not doing anything special about the - character to index an array. This is considered a normal error.

Note

Unlike in the default path mode, the array indices here are 0-based (in accordance with the RFC 6901 standard)

Warning

Not checking if the member that is referenced is unique. (according to the standard, evaluation of non-unique references should fail). Like json_get_by_path_default, this one will just return the first instance it encounters. This might be changed in the future.

Warning

I think the standard indicates that the input paths should use escaped JSON strings (currently we are assuming they are not escaped).

Type Bound
