Detailed Description

The state of one named file within an edit_context: the filename,
and the lines that have been edited so far.   

Constructor & Destructor Documentation

edited_file()

edited_file::edited_file	(	edit_context &	ec,
		const char *	filename )

edited_file's constructor.   

Member Function Documentation

apply_fixit()

bool edited_file::apply_fixit	(	int	line,
		int	start_column,
		int	next_column,
		const char *	replacement_str,
		int	replacement_len )

Attempt to replace columns START_COLUMN up to but not including NEXT_COLUMN
of LINE with the string REPLACEMENT_STR of length REPLACEMENT_LEN,
updating the in-memory copy of the line, and the record of edits to
the line.

delete_cb()

void edited_file::delete_cb ( edited_file * file )

static

A callback for deleting edited_file *, for use as a
delete_value_fn for edit_context::m_files.   

get_content()

char * edited_file::get_content

(

)

Get the content of the file, with fix-its applied.
The ptr should be freed by the caller.

get_effective_column()

int edited_file::get_effective_column	(	int	line,
		int	column )

Given line LINE, map from COLUMN in the input file to its current
column after edits have been applied.   

References get_line().

get_effective_line_count()

int edited_file::get_effective_line_count ( int old_start_of_hunk, int old_end_of_hunk )

private

Determine the number of lines that will be present after
editing for the range of lines from OLD_START_OF_HUNK to
OLD_END_OF_HUNK inclusive.

get_line()

edited_line * edited_file::get_line ( int line )

get_num_lines()

int edited_file::get_num_lines ( bool * missing_trailing_newline )

private

Get the total number of lines in m_content, writing
true to *MISSING_TRAILING_NEWLINE if the final line
if missing a newline, false otherwise.

get_or_insert_line()

Get the state of LINE within the file, creating a state for it
if necessary.  Return NULL if an error occurs.

print_content()

bool edited_file::print_content ( pretty_printer * pp )

private

Attempt to print the content of the file to PP, with edits applied.
Return true if successful, false otherwise.
