[section:syntax Regular Expression Syntax]
|
|
|
|
This section covers the regular expression syntax used by this library,
|
|
this is a programmers guide, the actual syntax presented to your program's
|
|
users will depend upon the flags used during expression compilation.
|
|
|
|
There are three main syntax options available, depending upon how you
|
|
construct the regular expression object:
|
|
|
|
* [link boost_regex.syntax.perl_syntax Perl (this is the default behavior)].
|
|
* [link boost_regex.syntax.basic_extended POSIX extended (including the egrep and awk variations)].
|
|
* [link boost_regex.syntax.basic_syntax POSIX Basic (including the grep and emacs variations)].
|
|
|
|
You can also construct a regular expression that treats every character as a
|
|
literal, but that's not really a "syntax"!
