-package Diagnostics.JSON_Utils is
-
- JSON_FORMATTING : constant Boolean := True;
- -- Adds newlines and indentation to the output JSON.
- --
- -- NOTE: This flag could be associated with the gcc switch:
- -- '-fno-diagnostics-json-formatting'
-
- INDENT_SIZE : constant := 2;
- -- The number of spaces to indent each level of the JSON output.
-
- Indent_Level : Natural := 0;
- -- The current indentation level.
-
- procedure Begin_Block;
- -- Increase the indentation level by one
-
- procedure End_Block;
- -- Decrease the indentation level by one
-
- procedure Indent;
- -- Print the indentation for the line
-
- procedure NL_And_Indent;
- -- Print a new line
-
- procedure Write_Boolean_Attribute (Name : String; Value : Boolean);
- -- Write a JSON attribute with a boolean value.
- --
- -- The value is either 'true' or 'false' without any quotes
-
- procedure Write_Int_Attribute (Name : String; Value : Int);
-
- procedure Write_JSON_Escaped_String (Str : String);
- -- Write each character of Str, taking care of preceding each quote and
- -- backslash with a backslash. Note that this escaping differs from what
- -- GCC does.
- --
- -- Indeed, the JSON specification mandates encoding wide characters
- -- either as their direct UTF-8 representation or as their escaped
- -- UTF-16 surrogate pairs representation. GCC seems to prefer escaping -
- -- we choose to use the UTF-8 representation instead.
-
- procedure Write_String_Attribute (Name : String; Value : String);
- -- Write a JSON attribute with a string value.
- --
- -- The Value is surrounded by double quotes ("") and the special characters
- -- within the string are escaped.
