result_T

typedef int result_T

Function Documentation

do_digraph()

int do_digraph

(

int

c

)

handle digraphs after typing a character

Parameters

c

Returns

The digraph.

ex_loadkeymap()

void ex_loadkeymap

(

exarg_T *

eap

)

":loadkeymap" command: load the following lines as the keymap.

Parameters

eap

get_digraph()

int get_digraph

(

bool

cmdline

)

Get a digraph. Used after typing CTRL-K on the command line or in normal mode.

Parameters

cmdline

true when called from the cmdline

Returns

composed character, or NUL when ESC was used.

get_digraph_for_char()

char_u* get_digraph_for_char

(

int

val_arg

)

Find a digraph for "val". If found return the string to display it. If not found return NULL.

getdigraph()

int getdigraph	(	int	char1,
		int	char2,
		bool	meta_char
	)

Get digraph. Allow for both char1-char2 and char2-char1

Parameters

char1
char2
meta_char

Returns

The digraph.

keymap_ga_clear()

void keymap_ga_clear

(

garray_T *

kmap_ga

)

Frees the buf_T.b_kmap_ga field of a buffer.

keymap_init()

char* keymap_init

(

void

)

Set up key mapping tables for the 'keymap' option.

Returns

NULL if OK, an error message for failure. This only needs to be used when setting the option, not later when the value has already been checked.

listdigraphs()

void listdigraphs

(

bool

use_headers

)

putdigraph()

void putdigraph

(

char_u *

str

)

Add the digraphs in the argument to the digraph table. format: {c1}{c2} char {c1}{c2} char ...

Parameters

str
