| 2 | #include <regexp.h> |
| 3 | |
| 4 | string *regexp(string *list, string pattern) |
| 5 | string *regexp(string *list, string pattern, int opt) |
| 6 | |
| 7 | DESCRIPTION |
| 8 | Match the pattern <pattern> (interpreted according to <opt> if |
| 9 | given) against all strings in list, and return a new array with all |
| 10 | strings that matched. |
| 11 | |
| 12 | If there is an error in the regular expression, a runtime |
| 13 | error will be raised. |
| 14 | |
| 15 | EXAMPLE |
| 16 | string strs; |
| 17 | string pattern; |
| 18 | |
| 19 | if (regexp_package() == RE_PCRE) |
| 20 | pattern = "\\<help\\>.*\\<me\\>"; |
| 21 | else |
| 22 | pattern = "\\bhelp\\b.*\\bme\\b"; |
| 23 | |
| 24 | if (strs = regexp( ({"please, help me Sir John."}), |
| 25 | , pattern |
| 26 | )) |
| 27 | { |
| 28 | if (sizeof(strs) |
| 29 | write("It matches.\n"); |
| 30 | } |
| 31 | |
| 32 | The regular expression will test the given string (which is |
| 33 | packed into an array) if there is something like "help ... me" |
| 34 | inside of it. |
