COMMENT(!MOD!zsh/regex
Interface to the POSIX regex library.
!MOD!)
cindex(regular expressions)
cindex(regex)
The tt(zsh/regex) module makes available the following test condition:
startitem()
findex(regex-match)
item(var(expr) tt(-regex-match) var(regex))(
Matches a string against a POSIX extended regular expression.
On successful match,
matched portion of the string will normally be placed in the tt(MATCH)
variable. If there are any capturing parentheses within the regex, then
the tt(match) array variable will contain those.
If the match is not successful, then the variables will not be altered.
For example,
example([[ alphabetical -regex-match ^a+LPAR()[^a]PLUS()+RPAR()a+LPAR()[^a]+PLUS()+RPAR()a ]] &&
print -l $MATCH X $match)
If the option tt(REMATCH_PCRE) is not set, then the tt(=~) operator will
automatically load this module as needed and will invoke the
tt(-regex-match) operator.
If tt(BASH_REMATCH) is set, then the array tt(BASH_REMATCH) will be set
instead of tt(MATCH) and tt(match).
