2.4.6 Redisplay
- Function: void rl_redisplay (void)
- Change what's displayed on the screen to reflect the current contents
of
rl_line_buffer
.
- Function: int rl_forced_update_display (void)
- Force the line to be updated and redisplayed, whether or not
Readline thinks the screen display is correct.
- Function: int rl_on_new_line (void)
- Tell the update functions that we have moved onto a new (empty) line,
usually after ouputting a newline.
- Function: int rl_on_new_line_with_prompt (void)
- Tell the update functions that we have moved onto a new line, with
rl_prompt already displayed.
This could be used by applications that want to output the prompt string
themselves, but still need Readline to know the prompt string length for
redisplay.
It should be used after setting rl_already_prompted.
- Function: int rl_reset_line_state (void)
- Reset the display state to a clean state and redisplay the current line
starting on a new line.
- Function: int rl_crlf (void)
- Move the cursor to the start of the next screen line.
- Function: int rl_show_char (int c)
- Display character c on
rl_outstream
.
If Readline has not been set to display meta characters directly, this
will convert meta characters to a meta-prefixed key sequence.
This is intended for use by applications which wish to do their own
redisplay.
- Function: int rl_message (const char *, ...)
- The arguments are a format string as would be supplied to
printf
,
possibly containing conversion specifications such as `%d', and
any additional arguments necessary to satisfy the conversion specifications.
The resulting string is displayed in the echo area. The echo area
is also used to display numeric arguments and search strings.
- Function: int rl_clear_message (void)
- Clear the message in the echo area.
- Function: void rl_save_prompt (void)
- Save the local Readline prompt display state in preparation for
displaying a new message in the message area with
rl_message()
.
- Function: void rl_restore_prompt (void)
- Restore the local Readline prompt display state saved by the most
recent call to
rl_save_prompt
.
- Function: int rl_expand_prompt (char *prompt)
- Expand any special character sequences in prompt and set up the
local Readline prompt redisplay variables.
This function is called by
readline()
. It may also be called to
expand the primary prompt if the rl_on_new_line_with_prompt()
function or rl_already_prompted
variable is used.
It returns the number of visible characters on the last line of the
(possibly multi-line) prompt.
- Function: int rl_set_prompt (const char *prompt)
- Make Readline use prompt for subsequent redisplay. This calls
rl_expand_prompt()
to expand the prompt and sets rl_prompt
to the result.
