srchilite::TextStyle Class Reference

Represents a formatting template where there can be some variables (starting with $, e.g., $style, $text, etc.) that will be replaced with specific elements, e.g., the actual style for the formatting, the text to format, etc. More...

Constructor & Destructor Documentation

srchilite::TextStyle::TextStyle	(	const std::string &	s = "",
		const char **	vars = 0
	)

Parameters

s	the representation
vars	an array of string representing the variables in this TextStyle (e.g., {"linenum", "infilename", "infile", "outfile", 0}), the last element must be 0

void srchilite::TextStyle::build_vectors ( )

private

The parts vector contains the string repr split in parts: those that constant parts and those that represent $text and $style variables.

For instance, if repr == "<span class=\"$style">$text", then we have:

• parts[0] == "<span class=\"" - parts[1] == "" - parts[2] == "">" - parts[3] == "" - parts[4] == ""

Then style_substitutions contains the index(es) of parts corresponding to $style variable occurrences that will be substituted with values and text_substitutions is the same but for $text occurrences. Thus, in this case:

• style_substitutions[0] = 1
• text_substitutions[0] = 3

TextStyle srchilite::TextStyle::compose

(

const TextStyle &

inner

)

substitutes $text with the string representation of inner e.g., if this is $text and inner is $text this will return $text

Parameters

inner

Returns

a new TextStyle after substitution

bool srchilite::TextStyle::containsStyleVar

(

)

const

Returns

whether this TextStyle contains the $style variable

bool srchilite::TextStyle::empty

(

)

const

Returns

whether it is only $style or $text

string srchilite::TextStyle::output	(	const std::string &	text,
		const std::string &	style = ""
	)

substitutes $text with text and $style with style

First substitute in the vector parts the values for $text and $style and return a string with the substituted values.

Parameters

text
style

Returns

the string after substitutions

Parameters

text
style

Returns

std::string srchilite::TextStyle::output

(

SubstitutionMapping &

subst_map

)

for each i substitutes: subst_map[i].first occurrence with subst_map[i].second

Parameters

subst_map

Returns

the string after substitutions

string srchilite::TextStyle::subst_style

(

const std::string &

style = ""

)

substitutes $style with style

Parameters

style

Returns

the string after substitutions

const std::string& srchilite::TextStyle::toString ( ) const

inline

Returns

the string representation

void srchilite::TextStyle::update

(

const TextStyle &

inner

)

as compose, but acts on this instance

Parameters

inner

void srchilite::TextStyle::update

(

const std::string &

inner

)

as compose, but acts on this instance

Parameters

inner

void srchilite::TextStyle::update	(	const std::string &	text,
