os::String Format_Perl::GetIndentString	(	const os::String &	cText,
		bool	bUseTabs,
		uint	nTabSize
	)

virtual

Get the string used to prefix the next line.

The format will analyze the given line and return a string to be used as prefix to the next line. This may be used to implement auto indenting of code.

As an example, for C++ the line "\t\tFlush();" may return the string "\t\t".

Parameters

cText	The line to analyze.
bUseTabs	Use TABs to indent.
nTabSize	Length of each TAB.

Returns: The string to prefix the next string with.

See Also: CodeView::setTabSize(); CodeView::getTabSize(); CodeView::setUseTab(); CodeView::getUseTab()

Implements cv::Format.

uint Format_Perl::GetNextWordLimit	(	const os::String &	cLine,
		uint	nChr
	)

virtual

Get the character index of the next word limit.

What is considered a word is up to the format.

Parameters

nLine	The line to analyze.
nChr	The character index to start from.

Returns: The character index of the next word limit, or the length if the string if none are found.

Implements cv::Format.

uint Format_Perl::GetPreviousWordLimit	(	const os::String &	cLine,
		uint	nChr
	)

virtual

Get the character index of the previous word limit.

What is considered a word is up to the format.

Parameters

nLine	The line to analyze.
nChr	The character index to start from.

Returns: The character index of the previous word limit, or 0 if the string if none are found.

Implements cv::Format.

const CodeViewStyle & Format_Perl::GetStyle ( char nStyle )

virtual

Get the color used to display the given style.

This method must return a color for each of the styles in the range from 0 through getStyleCount()-1. The method is not defined for methods outside of this range, but implementors are encouraged to handle this gracefully.

Parameters

nStyle The number of the style to return.

Returns: The color to display the given style with.

Implements cv::Format.

uint Format_Perl::GetStyleCount ( )

virtual

Get the number of different styles supported by this format.

Each format has a maximum number of styles it may use. This number can be in the range 1-255, and should not change during use, but the format is not required to actually use all of them.

Returns: The number of styles supported by this format.

Implements cv::Format.

const os::String & Format_Perl::GetStyleName ( char nStyle )

virtual

Get the name of the given style.

This method must return a name for each of the styles in the range from 0 through getStyleCount()-1. The method is not defined for styles outside of this range, but implementors are encouraged to handle this gracefully.

The names are intended used in configuration dialogs.

Parameters

style The number of the style to return.

Returns: A string containing the display name of the given style.

Implements cv::Format.

CodeViewContext Format_Perl::Parse	(	const os::String &	cText,
		os::String &	cStyle,
		CodeViewContext	nContext
	)

virtual

Parse a line and assign styles to each character.

The method will parse a single line of text and store the correct style to use for each character. After the method returns, character text[n] should be displayed using the style stored in style[n].

The format is responsible for resizing the style string to the correct size.

To correctly parse constructs spanning multiple lines, the format may store per-line context information in a 32-bit value. For the first line this value is defined to be 0, but for all other lines the value returned for the previous line should be passed as the context parameter.

Parameters

text	The line of text to parse.
style	A string to put the styles into.
context	A value representing the current context.

Returns: A value representing the new context.

Implements cv::Format.

void Format_Perl::SetStyle	(	char	nStyle,
		const CodeViewStyle &	cStyle
	)

virtual

Set the color used to display the given style.

This method must accept a color for each of the styles in the range from 0 through getStyleCount()-1. The method is not defined for methods outside of this range, but implementors are encouraged to handle this gracefully.

Parameters

nStyle	The number of the style to set.
cStyle	The color to display the given style with.

Implements cv::Format.
