RegExp

RegExp is a class to handle regular expressions.

It is the core foundation for adding powerful string pattern matching capabilities to programs like grep, text editors, awk, sed, etc.

Constructors

Functions

compile void compile(string pattern, string attributes): Undocumented in source. Be warned that the author may not have intended to support it.
exec string[] exec(string s): Search string[] for match.
exec string[] exec(): Pick up where last exec(string) or exec() left off, searching string[] for next match.
find sizediff_t find(string string): Search string[] for match with regular expression.
match string match(size_t n): Same as opIndex(n).
match string[] match(string s): Search s[] for match.
opApply int opApply(int delegate(ref RegExp) dg): Set up for start of foreach loop.
opIndex string opIndex(size_t n): Retrieve match n.
replace string replace(string s, string format): Find regular expression matches in s[]. Replace those matches with a new string composed of format[] merged with the result of the matches. If global, replace all matches. Otherwise, replace first match.
replace string replace(string format): After a match is found with test(), this function will take the match results and, using the format string, generate and return a new string.
replaceOld string replaceOld(string format): * Like replace(char[] format), but uses old style formatting: <table border=1 cellspacing=0 cellpadding=5> <th>Format <th>Description <tr> <td>& <td>replace with the match </tr> <tr> <td>\n <td>replace with the nth parenthesized match, n is 1..9 </tr> <tr> <td>\c <td>replace with char c. </tr> </table>
search RegExp search(string string): Set up for start of foreach loop.
split string[] split(string s): Split s[] into an array of strings, using the regular expression as the separator.
test bool test(string s): * Search s[] for match. * Returns: 0 for no match, !=0 for match * Example:
test int test(): Pick up where last test(string) or test() left off, and search again.
test int test(string s, size_t startindex): Test s[] starting at startindex against regular expression.

Properties

post string post [@property getter]: Return the slice of the input that follows the matched substring.
pre string pre [@property getter]: Return the slice of the input that precedes the matched substring.
