void AppendToRedobuff ( const char * s )

void AppendToRedobuffLit	(	const char_u *	str,

Append to Redo buffer literally, escaping special characters with CTRL-V. K_SPECIAL and CSI are escaped as well.

Parameters

str	String to append
len	Length of `str` or -1 for up to the NUL.

	)

Sets or removes a mapping or abbreviation in buffer buf.

Parameters

maptype

See also: do_map

Parameters

args	Fully parsed and "preprocessed" arguments for the (un)map/abbrev command. Termcodes should have already been replaced; whitespace, `<` and `>` signs, etc. in {lhs} and {rhs} are assumed to be literal components of the mapping.

[in]	modechars	Mode(s) in which mappings are checked.
[in]	abbr	true if checking abbreviations in place of mappings.

Returns: true if there is at least one mapping with given parameters.

Parameters

[in]	rhs	String which mapping must have in the rhs. Termcap codes are recognized in this argument.
[in]	mode	Mode(s) in which mappings are checked.

		const char_u *	orig_rhs,
		const size_t	orig_rhs_len,
		int	cpo_flags,
		MapArguments *	mapargs
	)

Replace termcodes in the given LHS and RHS and store the results into the lhs and rhs of the given MapArguments struct.

rhs and orig_rhs will both point to new allocated buffers. orig_rhs will hold a copy of the given orig_rhs.

The *_len variables will be set appropriately. If the length of the final lhs exceeds MAXMAPLEN, lhs_len will be set equal to the original larger length and lhs will be truncated.

If RHS is equal to "<Nop>", rhs will be the empty string, rhs_len will be zero, and rhs_is_noop will be set to true.

Any memory allocated by replace_termcodes is freed before this function returns.

Parameters

[in]	orig_lhs	Original mapping LHS, with characters to replace.
[in]	orig_lhs_len	`strlen` of orig_lhs.
[in]	orig_rhs	Original mapping RHS, with characters to replace.
[in]	orig_rhs_len	`strlen` of orig_rhs.
[in]	cpo_flags	See param docs for replace_termcodes.
[out]	mapargs	MapArguments struct holding the replaced strings.

int str_to_mapargs	(	const char_u *	strargs,
		bool	is_unmap,
		MapArguments *	mapargs
	)

Parse a string of |:map-arguments| into a MapArguments struct.

Termcodes, backslashes, CTRL-V's, etc. inside the extracted {lhs} and {rhs} are replaced by set_maparg_lhs_rhs.

rhs and orig_rhs in the returned mapargs will be set to null or a pointer to allocated memory and should be freed even on error.

Parameters

[in]	strargs	String of map args, e.g. "<buffer> <expr><silent>". May contain leading or trailing whitespace.
[in]	is_unmap	True, if strargs should be parsed like an \|:unmap\| command. \|:unmap\| commands interpret all text to the right of the last map argument as the {lhs} of the mapping, i.e. a literal ' ' character is treated like a "<space>", rather than separating the {lhs} from the {rhs}.
[out]	mapargs	MapArguments struct holding all extracted argument values.

Returns: 0 on success, 1 if invalid arguments are detected.
