Function Documentation

void add_pack_start_dirs

(

void

)

Add all packages in the "start" directory to 'runtimepath'.

int autowrite	(	buf_T *	buf,
		int	forceit
	)

If 'autowrite' option set, try to write the file. Careful: autocommands may make "buf" invalid!

Returns

FAIL for failure, OK otherwise

void autowrite_all

(

void

)

Flush all buffers, except the ones that are readonly or are never written.

int buf_write_all	(	buf_T *	buf,
		int	forceit
	)

Flush the contents of a buffer, unless it has no file name.

Returns

FAIL for failure, OK otherwise

bool can_abandon	(	buf_T *	buf,
		int	forceit
	)

Return true if the buffer "buf" can be abandoned, either by making it hidden, autowriting it or unloading it.

void check_arg_idx

(

win_T *

win

)

Check if window "win" is editing the w_arg_idx file in its argument list.

bool check_changed	(	buf_T *	buf,
		int	flags
	)

Return true if buffer was changed and cannot be abandoned. For flags use the CCGD_ values.

bool check_changed_any	(	bool	hidden,
		bool	unload
	)

Check if any buffer was changed and cannot be abandoned. That changed buffer becomes the current buffer. When "unload" is true the current buffer is unloaded instead of making it hidden. This is used for ":q!".

Parameters

[in]	hidden	specifies whether to check only hidden buffers.
[in]	unload	specifies whether to unload, instead of hide, the buffer.

Returns

true if any buffer is changed and cannot be abandoned

int check_fname

(

void

)

Return FAIL if there is no file name, OK if there is one. Give error message for FAIL.

void dbg_breakpoint	(	char_u *	name,
		linenr_T	lnum
	)

Called when a breakpoint was encountered.

void dbg_check_breakpoint

(

exarg_T *

eap

)

Go to debug mode when a breakpoint was encountered or "ex_nesting_level" is at or below the break level. But only when the line is actually executed. Return true and set breakpoint_name for skipped commands that decide to execute something themselves. Called from do_one_cmd() before executing a command.

bool dbg_check_skipped

(

exarg_T *

eap

)

Go to debug mode if skipped by dbg_check_breakpoint() because eap->skip was set.

Returns

true when the debug mode is entered this time.

linenr_T dbg_find_breakpoint	(	bool	file,
		char_u *	fname,
		linenr_T	after
	)

Find a breakpoint for a function or sourced file. Returns line number at which to break; zero when no matching breakpoint.

void dialog_changed	(	buf_T *	buf,
		bool	checkall
	)

Ask the user what to do when abandoning a changed buffer. Must check 'write' option first!

Parameters

buf
checkall	may abandon all changed buffers

bool dialog_close_terminal

(

buf_T *

buf

)

Ask the user whether to close the terminal buffer or not.

Parameters

buf	The terminal buffer.

Returns

bool Whether to close the buffer or not.

void do_argfile	(	exarg_T *	eap,
		int	argn
	)

Edit file "argn" of the argument lists.

void do_debug

(

char_u *

cmd

)

Debug mode. Repeatedly get Ex commands, until told to continue normal execution.

void do_finish	(	exarg_T *	eap,
		int	reanimate
	)

Mark a sourced file as finished. Possibly makes the ":finish" pending. Also called for a pending finish at the ":endtry" or after returning from an extra do_cmdline(). "reanimate" is used in the latter case.

int do_in_path	(	char_u *	path,
		char_u *	name,
		int	flags,
		DoInRuntimepathCB	callback,
		void *	cookie
	)

Find the file "name" in all directories in "path" and invoke "callback(fname, cookie)". "name" can contain wildcards. When "flags" has DIP_ALL: source all files, otherwise only the first one. When "flags" has DIP_DIR: find directories instead of files. When "flags" has DIP_ERR: give an error message if there is no match.

return FAIL when no file could be sourced, OK otherwise.

int do_in_path_and_pp	(	char_u *	path,
		char_u *	name,
		int	flags,
		DoInRuntimepathCB	callback,
		void *	cookie
	)

Find "name" in "path". When found, invoke the callback function for it: callback(fname, "cookie") When "flags" has DIP_ALL repeat for all matches, otherwise only the first one is used. Returns OK when at least one match found, FAIL otherwise. If "name" is NULL calls callback for each entry in "path". Cookie is passed by reference in this case, setting it to NULL indicates that callback has done its job.

int do_in_runtimepath	(	char_u *	name,
		int	flags,
		DoInRuntimepathCB	callback,
		void *	cookie
	)

Just like do_in_path_and_pp(), using 'runtimepath' for "path".

int do_source	(	char_u *	fname,
		int	check_other,
		int	is_vimrc
	)

Read the file "fname" and execute its lines as EX commands.

This function may be called recursively!

Parameters

fname
check_other	check for .vimrc and _vimrc
is_vimrc	DOSO_ value

Returns

FAIL if file could not be opened, OK otherwise
