Function Documentation

◆ buf_copy_options()

void buf_copy_options	(	buf_T *	buf,
		int	flags
	)

Copy global option values to local options for one buffer. Used when creating a new buffer and sometimes when entering a buffer. flags: BCO_ENTER We will enter the buffer "buf". BCO_ALWAYS Always copy the options, but only set b_p_initialized when appropriate. BCO_NOHELP Don't copy the values to a help buffer.

◆ can_bs()

Check if backspacing over something is allowed.

Parameters

what	BS_INDENT, BS_EOL, BS_START, or BS_NOSTOP

◆ check_blending()

◆ check_ff_value()

int check_ff_value ( char_u * p )

return OK if "p" is a valid fileformat name, FAIL otherwise.

◆ check_options()

void check_options ( void )

Check for string options that are NULL (normally only termcap options).

◆ check_signcolumn()

int check_signcolumn ( char_u * val )

Handle setting 'signcolumn' for value 'val'

Returns: OK when the value is valid, FAIL otherwise

◆ check_stl_option()

char* check_stl_option ( char_u * s )

Check validity of options with the 'statusline' format. Return an untranslated error message or NULL.

◆ check_win_options()

void check_win_options ( win_T * win )

Check string options in a window for a NULL value.

◆ clear_string_option()

void clear_string_option ( char_u ** pp )

◆ clear_winopt()

void clear_winopt ( winopt_T * wop )

Free the allocated memory inside a winopt_T.

◆ comp_col()

void comp_col ( void )

◆ copy_option_part()

size_t copy_option_part	(	char_u **	option,
		char_u *	buf,
		size_t	maxlen,
		char *	sep_chars
	)

Isolate one part of a string option separated by sep_chars.

Parameters

[in,out]	option	advanced to the next part
[in,out]	buf	copy of the isolated part
[in]	maxlen	length of `buf`
[in]	sep_chars	chars that separate the option parts

Returns: length of *option

◆ copy_winopt()

void copy_winopt	(	winopt_T *	from,
		winopt_T *	to
	)

Copy the options from one winopt_T to another. Doesn't free the old option values in "to", use clear_winopt() for that. The 'scroll' option is not copied, because it depends on the window height. The 'previewwindow' option is reset, there can be only one preview window.

◆ csh_like_shell()

int csh_like_shell ( void )

Return true when 'shell' has "csh" in the tail.

◆ default_fileformat()

int default_fileformat ( void )

Return the default fileformat from 'fileformats'.

◆ didset_window_options()

void didset_window_options ( win_T * wp )

◆ do_set()

int do_set	(	char_u *	arg,
		int	opt_flags
	)

Parse 'arg' for option settings.

'arg' may be IObuff, but only when no errors can be present and option does not need to be expanded with option_expand(). "opt_flags": 0 for ":set" OPT_GLOBAL for ":setglobal" OPT_LOCAL for ":setlocal" and a modeline OPT_MODELINE for a modeline OPT_WINONLY to only set window-local options OPT_NOWIN to skip setting window-local options

Parameters

arg	option string (may be written to!)

Returns: FAIL if an error is detected, OK otherwise

◆ ex_set()

void ex_set ( exarg_T * eap )

◆ ExpandOldSetting()

void ExpandOldSetting	(	int *	num_file,
		char_u ***	file
	)

◆ ExpandSettings()

int ExpandSettings	(	expand_T *	xp,
		regmatch_T *	regmatch,
		int *	num_file,
		char_u ***	file
	)

◆ file_ff_differs()

bool file_ff_differs	(	buf_T *	buf,
		bool	ignore_empty
	)

Return true if 'fileformat' and/or 'fileencoding' has a different value from when editing started (save_file_ff() called). Also when 'endofline' was changed and 'binary' is set, or when 'bomb' was changed and 'binary' is not set. Also when 'endofline' was changed and 'fixeol' is not set. When "ignore_empty" is true don't consider a new, empty buffer to be changed.

◆ find_key_option_len()

int find_key_option_len	(	const char_u *	arg_arg,
		size_t	len,
		bool	has_lt
	)

◆ find_shada_parameter()

char_u* find_shada_parameter ( int type )

Find the parameter represented by the given character (eg ''', ':', '"', or '/') in the 'shada' option and return a pointer to the string after it. Return NULL if the parameter is not specified in the string.

◆ findoption_len()

int findoption_len	(	const char *const	arg,
		const size_t	len
	)

Find index for named option

Parameters

[in]	arg	Option to find index for.
[in]	len	Length of the option.

Returns: Index of the option or -1 if option was not found.

◆ fish_like_shell()

bool fish_like_shell ( void )

Return true when 'shell' has "fish" in the tail.

◆ free_string_option()

void free_string_option ( char_u * p )

Free the string allocated for an option. Checks for the string being empty_option. This may happen if we're out of memory, vim_strsave() returned NULL, which was replaced by empty_option by check_options(). Does NOT check for P_ALLOCED flag!

◆ get_all_vimoptions()

Dictionary get_all_vimoptions ( void )

◆ get_bkc_value()

unsigned int get_bkc_value ( buf_T * buf )

Get the local or global value of 'backupcopy'.

Parameters

◆ get_fileformat()

int get_fileformat ( const buf_T * buf )

Return the current end-of-line type: EOL_DOS, EOL_UNIX or EOL_MAC.

◆ get_fileformat_force()

int get_fileformat_force	(	const buf_T *	buf,
		const exarg_T *	eap
	)

◆ langmap_adjust_mb()

int langmap_adjust_mb ( int c )

Apply 'langmap' to multi-byte character "c" and return the result.

◆ makefoldset()

int makefoldset ( FILE * fd )

Generate set commands for the local fold options only. Used when 'sessionoptions' or 'viewoptions' contains "folds" but not "options".

◆ makeset()

int makeset	(	FILE *	fd,
		int	opt_flags,
		int	local_only
	)

Write modified options as ":set" commands to a file.

There are three values for "opt_flags": OPT_GLOBAL: Write global option values and fresh values of buffer-local options (used for start of a session file). OPT_GLOBAL + OPT_LOCAL: Idem, add fresh values of window-local options for curwin (used for a vimrc file). OPT_LOCAL: Write buffer-local option values for curbuf, fresh and local values for window-local options of curwin. Local values are also written when at the default value, because a modeline or autocommand may have set them when doing ":edit file" and the user has set them back at the default or fresh value. When "local_only" is true, don't write fresh values, only local values (for ":mkview"). (fresh value = value used for a new buffer or window for a local option).

Return FAIL on error, OK otherwise.

Initialize the options, first part.

Called only once from main(), just after creating the first buffer. If "clean_arg" is true, Nvim was started with –clean.

◆ set_init_3()

void set_init_3 ( void )

Parameters

[in]	name	Option name.
[in]	number	New value for the number or boolean option.
[in]	string	New value for string option.
[in]	opt_flags	Flags: OPT_LOCAL, OPT_GLOBAL, or 0 (both). If OPT_CLEAR is set, the value of the option is cleared (the exact semantics of this depend on the option).

		int	opt_idx,
		const char_u *	val,
		int	opt_flags,

	)

Set a string option to a new value (without checking the effect). The string is copied into allocated memory. if ("opt_idx" == -1) "name" is used, otherwise "opt_idx" is used.

Parameters

void set_title_defaults ( void )

'title' and 'icon' only default to true if they have not been set or reset in .vimrc and we can read the old value. When 'title' and 'icon' have been reset in .vimrc, we won't even check if they can be reset. This reduces startup time when using X on a remote machine.
