Detailed Description

Uses a stream for ex mode processing.

Line numbers are stc line numbers, so start at line 0. All modifications are done in the temp file, and copied to the work file upon changing. If you ask for a write, the work file is copied to the original file.

loc_t

enum class wex::ex_stream::loc_t

BEFORE	before address
AFTER	after address

Member Function Documentation

copy()

bool wex::ex_stream::copy	(	const addressrange &	range,
		const address &	dest )

Copies range to destination.

Returns false if no stream, or range or dest is invalid.

find()

bool wex::ex_stream::find ( const std::string & text, int find_flags = -1, bool find_next = true )

overridevirtual

Pure virtual interface.

Finds next or previous.

Parameters

text	text to find
find_flags	search flags to be used: wxSTC_FIND_WHOLEWORD wxSTC_FIND_MATCHCASE wxSTC_FIND_WORDSTART wxSTC_FIND_REGEXP wxSTC_FIND_POSIX if -1, use flags from find replace data
find_next	finds next or previous

Implements wex::factory::text_window.

get_lines()

bool wex::ex_stream::get_lines	(	const addressrange &	range,
		const std::string &	flags = "" )

Builds a string with text from range, result present in text.

Returns false if no stream, or range is invalid.

Parameters

range	the range
flags	flags to specify behaviour, see get_lines at ex/util.h

insert_text()

bool wex::ex_stream::insert_text	(	int	line,
		const std::string &	text,
		loc_t	loc = loc_t::BEFORE )

Inserts text at specified line.

Returns false if no stream, or address is invalid.

is_block_mode()

bool wex::ex_stream::is_block_mode ( ) const

inline

Returns true if we are in block mode.

Block mode implies that no eols were found when reading lines with max size.

join()

bool wex::ex_stream::join

(

const addressrange &

range

)

Joins all lines in the range.

Returns false if no stream, or range is invalid.

marker_add()

bool wex::ex_stream::marker_add	(	char	marker,
		int	line )

Sets marker.

Returns false if marker is invalid.

marker_line()

int wex::ex_stream::marker_line

(

char

marker

)

const

Returns line for marker.

Returns LINE_NUMBER_UNKNOWN if marker not known.

move()

bool wex::ex_stream::move	(	const addressrange &	range,
		const address &	dest )

Moves range to destination.

Returns false if no stream, or range or dest is invalid.

stream()

void wex::ex_stream::stream	(	file &	f,
		size_t	default_line_size = 100000 )

Sets the streams and default line size.

Puts first line on stc. This must be called before the other methods.

substitute()

bool wex::ex_stream::substitute	(	const addressrange &	range,
		const data::substitute &	data )

Substitutes within the range find by replace.

Returns false if no stream, or range is invalid.

write() [1/2]

bool wex::ex_stream::write

(

)

Writes working stream to file.

Returns false if internal streams are not valid.

write() [2/2]

bool wex::ex_stream::write	(	const addressrange &	range,
		const std::string &	file,
		bool	append = false )

Writes range to file.

Returns false if no stream, or range is invalid.

yank()

bool wex::ex_stream::yank	(	const addressrange &	range,
		char	name = '0' )

Yanks range to register, default to yank register.

Returns false if no stream, or range is invalid.
