Operator=(const QRegularExpression & re) constДЄ regexp can test whether a substring meets some criteria, e.g. Operator!=(const QRegularExpression & re) const SetPatternOptions(QRegularExpression::PatternOptions options) Match(QStringView subject, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const Match(const QStringRef & subjectRef, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const Match(const QString & subject, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const GlobalMatch(QStringView subject, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const GlobalMatch(const QStringRef & subjectRef, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const GlobalMatch(const QString & subject, int offset = 0, QRegularExpression::MatchType matchType = NormalMatch, QRegularExpression::MatchOptions matchOptions = NoMatchOption) const QRegularExpression(const QString & pattern, QRegularExpression::PatternOptions options = NoPatternOption) %ENV : The hash containing your current environment.QRegularExpression(const QRegularExpression & re) These entries are done via do, require or use operators. %INC : This variable contains the entries for the file name of each file that has been included.

This array needs a full package name because it is package-specific. Use lib : When we use the -a command-line switch we use to split and input the lines into an array. Here, a, b, c, d represents any numeric This variable can be considered as the inbuilt help array which contains the list of places to find scripts to be evaluated by the do, require, or use constructs. $ perl -e 'print join( ', ', ' '' a 'b c' d It is generally one value less than the total number of arguments. Global Array Special : In a command-line argument is the array which is used for the intended script. Here, it is said that itвЂ™s meaningless because here this variable( $!) is unrelated to the outcome of open() operator. If $/ is undefined, the entire file is read as a single input for null value a blank is considered as a delimiter. $/, $RS : This is the input record separator. This variable will never move the seek pointer in the file.

The value is reset to zero if the filehandle is closed. $., $NR : Contains the line number of the filehandle last updated. $_, $ARG : Used as a default variable to accept input and to perform pattern-searching, when variable is omitted.

And listed corresponding English like names along with the symbolic names. Global Scalar Special VariablesД«elow mentioned is the list of some of the scalar special variables. For example, for STDOUT, the default format name would be STDOUT itself. The default value is the name of the filehandle. $~, $FORMAT_NAME: The name of the current report format for the currently selected output channel. $-, $FORMAT_LINES_LEFT: Returns the number of lines left on the page of the currently selected output channel.

The default value for this variable is 60. the lines which are printable of the currently selected output channel. $=, $FORMAT_LINES_PER_PAGE: This variable returns the current page length i.e. $%, $FORMAT_PAGE_NUMBER: This variable finds the currently selected output channel and the current page number. $|, $OUTPUT_AUTOFLUSH: If set to nonzero, this variable forces a flush after every write or print statement on the output channel that is currently being selected.
