static

Search for a byte sequence in the action list.

Searches the unix_cli_parse_actions_t list in a for a match with the bytes in input of maximum length ilen bytes. When a match is made *matched indicates how many bytes were matched. Returns a value from the enum unix_cli_parse_action_t to indicate whether no match was found, a partial match was found or a complete match was found and what action, if any, should be taken.

Parameters

[in]	a	Actions list to search within.
[in]	input	String fragment to search for.
[in]	ilen	Length of the string in 'input'.
[out]	matched	Pointer to an integer that will contain the number of bytes matched when a complete match is found.

Returns: Action from unix_cli_parse_action_t that the string fragment matches. UNIX_CLI_PARSE_ACTION_PARTIALMATCH is returned when the whole input string matches the start of at least one action. UNIX_CLI_PARSE_ACTION_NOMATCH is returned when there is no match at all.

	)

static

Process and add a line to the pager index.

In normal operation this function will take the given character string found in line and with length len_or_index and iterates the over the contents, adding each line of text discovered within it to the pager index. Lines are identified by newlines ("<code>\\n</code>") and by strings longer than the width of the terminal.

If instead line is NULL then len_or_index is taken to mean the index of an existing line in the pager buffer; this simply means that the input line does not need to be cloned since we already have it. This is typical if we are reindexing the pager buffer.

Parameters

cf	The CLI session whose pager we are adding to.
line	The string of text to be indexed into the pager buffer. If `line` is `NULL` then the mode of operation changes slightly; see the description above.
len_or_index	If `line` is a pointer to a string then this parameter indicates the length of that string; Otherwise this value provides the index in the pager buffer of an existing string to be indexed.

◆ unix_vlib_cli_output()

static void unix_vlib_cli_output	(	uword	cli_file_index,
		u8 *	buffer,

static

VLIB CLI output function.

If the terminal has a pager configured then this function takes care of collating output into the pager buffer; ensuring only the first page is displayed and any lines in excess of the first page are buffered.

If the maximum number of index lines in the buffer is exceeded then the pager is cancelled and the contents of the current buffer are sent to the terminal.

If there is no pager configured then the output is sent directly to the terminal.

Parameters

cli_file_index	Index of the CLI session where this output is directed.
buffer	String of printabe bytes to be output.
buffer_bytes	The number of bytes in `buffer` to be output.

static void unix_vlib_cli_output_cursor_left	(	unix_cli_file_t *	cf,

	)

static

Moves the terminal cursor one character to the left, with special handling when it reaches the left edge of the terminal window.

Ordinarily we can simply send a '' to move the cursor left, however most terminals will not reverse-wrap to the end of the previous line if the cursor is in the left-most column. To counter this we must check the cursor position + prompt length modulo terminal width and if available use some other means, such as ANSI terminal escape sequences, to move the cursor.

Parameters

cf	Unix CLI session of the desired stream to write to.
uf	The Unix file structure of the desired stream to write to.

		uword	buffer_bytes
	)

static

Send a buffer to the CLI stream if possible, enqueue it otherwise.

Attempts to write given buffer to the file descriptor of the given Unix CLI session. If that session already has data in the output buffer or if the write attempt tells us to try again later then the given buffer is appended to the pending output buffer instead.

This is typically called only from unix_vlib_cli_output_cooked since that is where CRLF handling occurs or from places where we explicitly do not want cooked handling.

Parameters

cf	Unix CLI session of the desired stream to write to.
uf	The Unix file structure of the desired stream to write to.
buffer	Pointer to the buffer that needs to be written.
buffer_bytes	The number of bytes from `buffer` to write.

inlinestatic

A bit like strchr with a buffer length limit.

Search a buffer for the first instance of a character up to the limit of the buffer length. If found then return the position of that character.

The key departure from strchr is that if the character is not found then return the buffer length.

Parameters

chr	The byte value to search for.
str	The buffer in which to search for the value.
len	The depth into the buffer to search.

Returns: The index of the first occurrence of chr. If chr is not found then len instead.
