Msgpack.vim introduction msgpack.vim-intro This plugin contains utility functions to be used in conjunction with msgpackdump() and msgpackparse() functions. ============================================================================== 3. Msgpack.vim manual msgpack.vim-manual 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 to really work with msgpack-special-dicts. msgpack#strptime msgpack#strptime({format}, {time}) msgpack#strptime() Reverse of msgpack#strftime(): for any time and format msgpack#equal( msgpack#strptime(format, msgpack#strftime(format, time)), time) be true. Requires |Python, 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 single {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. ============================================================================== vim:tw=78:ts=8:ft=help:fdm=marker
