Syntax
native Regex:regex_compile(const pattern[], &ret = 0, error[] = "", maxLen = 0, const flags[]="");Description
Precompile a regular expression.
Parameters
| pattern | The regular expression pattern. |
|---|---|
| ret | Error code encountered, if applicable. |
| error | Error message encountered, if applicable. |
| maxLen | Maximum string length of the error buffer. |
| flags | General flags for the regular expression. i = Ignore case m = Multilines (affects ^ and $ so that they match the start/end of a line rather than matching the start/end of the string). s = Single line (affects . so that it matches any character, even new line characters). x = Pattern extension (ignore whitespace and # comments). |
Note
Use this if you intend on using the same expression multiple times.
Pass the regex handle returned here to regex_match_c to check for matches.
Note
This handle is automatically freed on map change. However,
if you are completely done with it before then, you should
call regex_free on this handle.
Note
Consider using regex_compile_ex instead if you want to use PCRE_* flags.
Return
-1 on error in the pattern, > valid regex handle (> 0) on success.
