DESCRIPTION

This file handles actions related to struct AS_TextBufs, such as character insertion and deletion.

Function Documentation

buffer_char_del()

void buffer_char_del

(

)

Deletes the current character.

Deletes the current character in as_ctx.text_file->active_buffer->current_element. If current_element is completely empty, then it will be deleted.

buffer_char_insert()

void buffer_char_insert

(

char

c

)

Inserts a new character into the active buffer.

Insert the given character into as_ctx.text_file->active_buffer->current_element.

Parameters

char	c - The character to be inserted. If it is '\n', then a new struct AS_LLElement will be inserted.

buffer_move_ln_down()

int buffer_move_ln_down

(

struct AS_TextBuf *

active_buffer

)

Moves the current line in the given buffer down.

Parameters

struct

AS_TextBuf *active_buffer - The buffer in which to move active_buffer->current_element down one.

Returns

Returns the number of lines moved down (0: if the function failed).

buffer_move_ln_up()

int buffer_move_ln_up

(

struct AS_TextBuf *

active_buffer

)

Moves the current line in the given buffer up.

Parameters

struct

AS_TextBuf *active_buffer - The buffer in which to move active_buffer->current_element up one.

Returns

Returns the number of lines moved up (0: if the function failed).

destroy_buffer()

void destroy_buffer

(

struct AS_TextBuf *

buffer

)

Frees a struct AS_TextBuf

Parameters

struct

AS_TextBUf *buffer - The buffer to be freed.

new_buffer()

struct AS_TextBuf * new_buffer	(	int	col_start,
		int	col_end )

Creates a new struct AS_TextBuf

Creates a new, and initializes all fields of a new struct AS_TextBuf.

Parameters

int	col_start - The 0-based index where the buffer's column starts
int	col_end - The 0-based index where the buffer's column ends

Returns

The pointer to the struct AS_TextBuf
