Constructor & Destructor Documentation

KateBuffer::KateBuffer ( KTextEditor::DocumentPrivate * doc )

explicit

Create an empty buffer.

Parameters

doc	parent document

(with one block with one empty line)

Definition at line 49 of file katebuffer.cpp.

KateBuffer::~KateBuffer ( )

override

Goodbye buffer.

Cleanup on destruction.

Definition at line 65 of file katebuffer.cpp.

Member Function Documentation

bool KateBuffer::brokenEncoding ( ) const

inline

Did encoding errors occur on load?

Returns: encoding errors occurred on load?

Definition at line 122 of file katebuffer.h.

bool KateBuffer::canEncode ( )

Can the current codec handle all chars.

Returns: chars can be encoded

Definition at line 224 of file katebuffer.cpp.

void KateBuffer::clear ( )

overridevirtual

Clear the buffer.

Reimplemented from Kate::TextBuffer.

Definition at line 136 of file katebuffer.cpp.

KTextEditor::Range KateBuffer::computeFoldingRangeForStartLine ( int startLine )

For a given line, compute the folding range that starts there to be used to fold e.g.

from the icon border

Parameters

startLine start line

Returns: folding range starting at the given line or invalid range

ensure valid input

no highlighting, no folding, ATM

first: get the wanted start line highlighted

return if no folding start!

now: decided if indentation based folding or not!

get our start indentation level

search next line with indentation level <= our one

get line

indentation higher than our start line? continue

empty line? continue

else, break

lastLine is always one too much

backtrack all empty lines, we don't want to add them to the fold!

we shall not fold one-liners

be done now

'normal' attribute based folding, aka token based like '{' BLUB '}'

first step: search the first region type, that stays open for the start line

mapping of type to "first" offset of it and current number of not matched openings

walk over all attributes of the line and compute the matchings

folding close?

search for this type, try to decrement counter, perhaps erase element!

folding open?

search for this type, either insert it, with current offset or increment counter!

compute first type with offset

no opening region found, bad, nothing to do

second step: search for matching end region marker!

ensure line is highlighted

search for matching end marker

matching folding close?

end reached? compute resulting range!

special handling of end: if end is at column 0 of a line, move it to end of previous line! fixes folding for stuff like #pragma mark END_OLD_AND_START_NEW_REGION

return computed range

matching folding open?

if we arrive here, the opened range spans to the end of the document!

Definition at line 452 of file katebuffer.cpp.

int KateBuffer::count ( ) const

inline

Return the total number of lines in the buffer.

Definition at line 183 of file katebuffer.h.

bool KateBuffer::editChanged ( ) const

inline

were there changes in the current running editing session?

Returns: changes done?

Definition at line 72 of file katebuffer.h.

void KateBuffer::editEnd ( )

finish some editing action

not finished, do nothing

nothing change, OK

if we arrive here, line changed should be OK

no highlighting, nothing to do

if we don't touch the highlighted area => fine

look one line too far, needed for linecontinue stuff

for indentation sensitive folding, we need to redo things one line up, to e.g. get notified about new folding starts see bug 351496

really update highlighting

Definition at line 76 of file katebuffer.cpp.

void KateBuffer::editStart ( )

start some editing action

Definition at line 69 of file katebuffer.cpp.

int KateBuffer::editTagEnd ( ) const

inline

dirty lines end

Returns: end line

Definition at line 90 of file katebuffer.h.

bool KateBuffer::editTagFrom ( ) const

inline

line inserted/removed?

Returns: line inserted/removed?

Definition at line 99 of file katebuffer.h.

int KateBuffer::editTagStart ( ) const

inline

dirty lines start

Returns: start line

Definition at line 81 of file katebuffer.h.

void KateBuffer::ensureHighlighted	(	int	line,
		int	lookAhead = `64`
	)

Update highlighting of given line line, if needed.

If line is already highlighted, this function does nothing. If line is not highlighted, all lines up to line + lookAhead are highlighted.

Parameters

lookAhead also highlight these following lines

Definition at line 276 of file katebuffer.cpp.

void KateBuffer::invalidateHighlighting ( )

Invalidate highlighting of whole buffer.

Definition at line 355 of file katebuffer.cpp.

bool KateBuffer::openFile	(	const QString &	m_file,
		bool	enforceTextCodec
	)

Open a file, use the given filename.

Parameters

m_file	filename to open
enforceTextCodec	enforce to use only the set text codec

Returns: success

allow non-existent files without error, if local file! will allow to do "kate newfile.txt" without error messages but still fail if e.g. you mistype a url and it can't be fetched via fish:// or other strange things in kio happen... just clear() + exit with success!

check if this is a normal file or not, avoids to open char devices or directories! else clear buffer and break out with error

try to load

Definition at line 150 of file katebuffer.cpp.

Kate::TextLine KateBuffer::plainLine ( int lineno )

inline

Return line lineno.

Highlighting of returned line might be out-dated, which may be sufficient for pure text manipulation functions, like search/replace. If you require highlighting to be up to date, call ensureHighlighted prior to this method.

Definition at line 162 of file katebuffer.h.

bool KateBuffer::saveFile ( const QString & m_file )

Save the buffer to a file, use the given filename + codec + end of line chars (internal use of qtextstream)

Parameters

m_file filename to save to

Returns: success

Definition at line 246 of file katebuffer.cpp.

void KateBuffer::setHighlight ( int hlMode )

Use highlight for highlighting.

highlight may be 0 in which case highlighting will be disabled.

Definition at line 326 of file katebuffer.cpp.

void KateBuffer::tagLines	(	int	start,
		int	end
	)

signal

Emitted when the highlighting of a certain range has changed.

bool KateBuffer::tooLongLinesWrapped ( ) const

inline

Too long lines wrapped on load?

Returns: too long lines wrapped on load?

Definition at line 131 of file katebuffer.h.

void KateBuffer::unwrapLine ( int line )

overridevirtual

Unwrap given line.

Parameters

line	line to unwrap

Reimplemented from Kate::TextBuffer.

Definition at line 305 of file katebuffer.cpp.

void KateBuffer::wrapLine ( const KTextEditor::Cursor & position )

overridevirtual

Wrap line at given cursor position.

Parameters

position line/column as cursor where to wrap

Reimplemented from Kate::TextBuffer.

Definition at line 295 of file katebuffer.cpp.
