class: etk::RegExp
Description:
Regular expression interface template.
List of elment that can be displayed :
(...) sub element is separate with |
\d Digits [0-9]
\D NOT a digit [^0-9]
\l Letters [a-zA-Z]
\L NOT a Letter [^a-zA-Z]
\s Whitespace [ \t\n\r\f\v]
\S NOT Whitespace [^ \t\n\r\f\v]
\w "Word" character [a-zA-Z0-9_]
\W NOT a "Word" character [^a-zA-Z0-9_]
\@ at the start or the end not in the parsing of element ==> check if \w is not present (other regExp will be <> ...)
[anjdi] or [a-gt-j] range
. dot [^\x00-\x08\x0A-\x1F\x7F]
==> TODO :
$ End / Start of line of line ==> ce sera un truc suplé comme le \@
^in the [] invertion of the range element
multiplicity :
==> {0, 2147483647}
? ==> {0, 1}
+ ==> {1, 2147483647}
{x} ==> {x, x}
{x,y} ==> {x, y}

Constructor
~RegExp
+ ~RegExp (void );
Destructor
compile
+ void compile (const std::string & _exp);
+ void compile (const std::u32string & _regexp);
Set a new regular expression matching
getRegExp
+ std::string getRegExp (void ) const;
+ const std::u32string & getURegExp (void ) const;
Get the regular expression string
| Return: | | the string representing the RegExp |
getStatus
+ bool getStatus (void );
Get the status if the regular expression parsing
| Return: | | true : the regExp is correctly parsed<br/>false : an error occcured (check log ...) |
parse
+ bool parse (const CLASS_TYPE & _SearchIn,
int64_t _startPos,
int64_t _endPos,
char32_t _escapeChar);
Parse the defined data with the compiled regular expression.
processOneElement
+ bool processOneElement (const CLASS_TYPE & _SearchIn,
int64_t _startPos,
int64_t _endPos,
char32_t _escapeChar);
start
+ int64_t start (void );
Get the expression start position detected
| Return: | | position of the start regExp |
stop
+ int64_t stop (void );
Get the expression stop position detected
| Return: | | position of the stop regExp |
display
+ void display (void );
Display the reg Exp
drawColoredRegEx
+ void drawColoredRegEx (void );
Just display the regExp in color ...
getRegExDecorated
+ std::string getRegExDecorated (void );
Get decorated regular expression. This generate a
ewol::compositing::Text decoration text. Note that can be use in
ewol::widget::Label.
| Return: | | The decorated string |
