2. Msgpack.vim introduction			*msgpack.vim-intro*

This plugin contains utility functions to be used in conjunction with 
|msgpackdump()| and |msgpackparse()| functions.

FUNCTION ARGUMENTS				*msgpack.vim-arguments*

Disambiguation of arguments described below.  Note: if e.g. function is listed 
as accepting |{msgpack-integer}| (or anything else) it means that function 
does not check whether argument matches its description.

*{msgpack-value}*	Either |msgpack-special-dict| or a regular value, but 
			not function reference.
*{msgpack-integer}*	Any value for which |msgpack#type()| will return 
			"integer".
*{msgpack-special-int}*	|msgpack-special-dict| representing integer.

msgpack#is_int({msgpack-value})				*msgpack#is_int()*
	Returns 1 if given {msgpack-value} is integer value, 0 otherwise.

msgpack#is_uint({msgpack-value})			*msgpack#is_uint()*
	Returns 1 if given {msgpack-value} is integer value greater or equal 
	to zero, 0 otherwise.

							*msgpack#strftime*
msgpack#strftime({format}, {msgpack-integer})		*msgpack#strftime()*
	Same as |strftime()|, but second argument may be 
	|msgpack-special-dict|.  Requires |+python| or |+python3| to really 
	work with |msgpack-special-dict|s.

							*msgpack#strptime*
msgpack#strptime({format}, {time})			*msgpack#strptime()*
	Reverse of |msgpack#strptime()|: for any time and format 
	|msgpack#equal|( |msgpack#strptime|(format, |msgpack#strftime|(format, 
	time)), time) be true.  Requires |+python| or |+python3|, without it 
	only supports non-|msgpack-special-dict| nonnegative times and format 
	equal to `%Y-%m-%dT%H:%M:%S`.

msgpack#int_dict_to_str({msgpack-special-int})	*msgpack#int_dict_to_str()*
	Function which converts |msgpack-special-dict| integer value to 
	a hexadecimal value like 0x1234567890ABCDEF (always returns exactly 16 
	hexadecimal digits).

msgpack#special_type({msgpack-value})		*msgpack#special_type()*
	Returns zero if {msgpack-value} is not |msgpack-special-dict|.  If it 
	is it returns name of the key in |v:msgpack_types| which represents 
	{msgpack-value} type.

msgpack#type({msgpack-value})				*msgpack#type()*
	Returns name of the key in |v:msgpack_types| that represents 
	{msgpack-value} type.  Never returns zero: this function returns 
	msgpack type which will be dumped by |msgpackdump()| should it receive 
	a list with singe {msgpack-value} as input.

msgpack#deepcopy({msgpack-value})			*msgpack#deepcopy()*
	Like |deepcopy()|, but works correctly with |msgpack-special-dict| 
	values.  Plain |deepcopy()| will destroy all types in 
	|msgpack-special-dict| values because it will copy _TYPE key values, 
	while they should be preserved.

msgpack#string({msgpack-value})				*msgpack#string()*
	Like |string()|, but saves information about msgpack types.  Values 
	dumped by msgpack#string may be read back by |msgpack#eval()|.  
	Returns is the following:

	- Dictionaries are dumped as "{key1: value1, key2: value2}". Note: 
	  msgpack allows any values in keys, so with some 
	  |msgpack-special-dict| values |msgpack#string()| may produce even 
	  "{{1: 2}: 3, [4]: 5}".
	- Lists are dumped as "[value1, value2]".
	- Strings are dumped as
	  1. `"abc"`: binary string.
	  2. `="abc"`: string.
	  3. `+(10)"ext"`: extension strings (10 may be replaced with any 
	     8-bit signed integer).
	  Inside strings the following escape sequences may be present: "\0" 
	  (represents NUL byte), "\n" (represents line feed) and "\"" 
	  (represents double quote).
	- Floating-point and integer values are dumped using |string()| or 
	  |msgpack#int_dict_to_str()|.
	- Booleans are dumped as "TRUE" or "FALSE".
	- Nil values are dumped as "NIL".

msgpack#eval({string}, {dict})				*msgpack#eval()*
	Transforms string created by |msgpack#string()| into a value suitable 
	for |msgpackdump()|.  Second argument allows adding special values 
	that start with head characters (|/\h|) and contain only word 
	characters (|/\w|).  Built-in special values are "TRUE", "FALSE", 
	"NIL", "nan" and "inf" and they cannot be overridden.  Map values are 
	always evaluated to |msgpack-special-dict| values, as well as 
	hexadecimal digits.  When evaluating maps order of keys is preserved.

	Note that in addition to regular integer representations that may be 
	obtained using |msgpack#string()| msgpack#eval() also supports C-style 
	“character” integer constants like `'/'` (equivalent to 
	`char2nr('/')`: `47`). This also allows `'\0'` (number is decimal).

							*msgpack#equal*
msgpack#equal({msgpack-value}, {msgpack-value})		*msgpack#equal()*
	Returns 1 if given values are equal, 0 otherwise.  When comparing 
	msgpack map values order of keys is ignored.  Comparing 
	|msgpack-special-dict| with equivalent non-special-dict value 
	evaluates to 1.
