Define Documentation

#define LINE_UNSIMPLIFIED   (GET_PUBLIC(line_edit,ops_cut) == false && GET_PUBLIC(line_edit,parens_deleted) == 0)

Say whether the current line has been simplified

Function Documentation

static void flushline_dummy	(	bool	keep,
		const char *	insert_text
	)		[static]

No-op implementation of flushline() selected when we are not executing a `source' command.

Definition at line 197 of file line_despatch.c.

Referenced by line_despatch_no_op().

static void flushline_live	(	bool	keep,
		char const *	insert_text
	)		[static]

Write a line to the output or drop it, according to command line options.

Parameters:

keep	Is the line to be kept of dropped?
insert_text	Either NULL or a pointer to a null-terminated diagnostic that is to be written instead of the line-buffer.

If insert_text is non-null then this string is output.

Otherwise is keep is true then the line-buffer is output unless the --complement option is in force.

If keep is false, or is true together with --complement, the line buffer is dropped. If the --blank is not in force then nothing is written to putput. Otherwise an empty line is written to output.

Here is the call graph for this function:

static void printline

(

void

[static]

Print a line buffer to output.

The function selects a more specialised helper function to which it delegates.

[static]

Print a line buffer to output commented out with the prefix "//coan".

[static]

Print a line buffer to output deleting chunks marked for unconditional deletion.

[static]

Print an unmodified line buffer to output with no complications

References GET_PUBLIC.

static void printline_restore_all_paren

(

void

)

[static]

Print an output line buffer that may contain superfluous parentheses marked for deletion, but no other parts marked for deletion.

In this case we have not materially simplified the line and just restore the parentheses before printing the line.

Here is the call graph for this function:

static void printline_slow

(

void

)

[static]

Print an output line buffer containing chunks marked for deletion.

We will delete all these chunks only if and only if some of them represent truth-functional simplifications of the line. Otherwise the only logical deletions will represent superfluous parentheses. We will then restore those parentheses before printing the line.
