The __last__ capture is embedded in each group, so `g.String()` will return the same thing as `g.Capture.String()` and `g.Captures[len(g.Captures)-1].String()`.
If you want to find multiple matches from a single input string you should use the `FindNextMatch` method. For example, to implement a function similar to `regexp.FindAllString`:
```go
func regexp2FindAllString(re *regexp2.Regexp, s string) []string {
var matches []string
m, _ := re.FindStringMatch(s)
for m != nil {
matches = append(matches, m.String())
m, _ = re.FindNextMatch(m)
}
return matches
}
```
`FindNextMatch` is optmized so that it re-uses the underlying string/rune slice.
The internals of `regexp2` always operate on `[]rune` so `Index` and `Length` data in a `Match` always reference a position in `rune`s rather than `byte`s (even if the input was given as a string). This is a dramatic difference between `regexp` and `regexp2`. It's advisable to use the provided `String()` methods to avoid having to work with indices.

* add support for named ascii character classes (e.g. `[[:foo:]]`)
* add support for python-style capture groups (e.g. `(P<name>re)`)
* change singleline behavior for `$` to only match end of string (like RE2) (see [#24](https://github.com/dlclark/regexp2/issues/24))
* change the character classes `\d` `\s` and `\w` to match the same characters as RE2. NOTE: if you also use the `ECMAScript` option then this will change the `\s` character class to match ECMAScript instead of RE2. ECMAScript allows more whitespace characters in `\s` than RE2 (but still fewer than the the default behavior).
* allow character escape sequences to have defaults. For example, by default `\_` isn't a known character escape and will fail to compile, but in RE2 mode it will match the literal character `_`

This feature is a work in progress and I'm open to ideas for more things to put here (maybe more relaxed character escaping rules?).
## Catastrophic Backtracking and Timeouts
`regexp2` supports features that can lead to catastrophic backtracking.
`Regexp.MatchTimeout` can be set to to limit the impact of such behavior; the
match will fail with an error after approximately MatchTimeout. No timeout
checks are done by default.
Timeout checking is not free. The current timeout checking implementation starts
a background worker that updates a clock value approximately once every 100
milliseconds. The matching code compares this value against the precomputed
deadline for the match. The performance impact is as follows.
1. A match with a timeout runs almost as fast as a match without a timeout.
2. If any live matches have a timeout, there will be a background CPU load
(`~0.15%` currently on a modern machine). This load will remain constant
regardless of the number of matches done including matches done in parallel.
3. If no live matches are using a timeout, the background load will remain
until the longest deadline (match timeout + the time when the match started)
is reached. E.g., if you set a timeout of one minute the load will persist
for approximately a minute even if the match finishes quickly.
Some alternative implementations were considered and ruled out.
1. **time.Now()** - This was the initial timeout implementation. It called `time.Now()`
and compared the result to the deadline approximately once every 1000 matching steps.
Adding a timeout to a simple match increased the cost from ~45ns to ~3000ns).
2. **time.AfterFunc** - This approach entails using `time.AfterFunc` to set an `expired`
atomic boolean value. However it increases the cost of handling a simple match
with a timeout from ~45ns to ~360ns and was therefore ruled out.
3. **counter** - In this approach an atomic variable tracks the number of live matches
with timeouts. The background clock stops when the counter hits zero. The benefit
of this approach is that the background load will stop more quickly (after the
last match has finished as opposed to waiting until the deadline for the last
match). However this approach requires more atomic variable updates and has poorer
performance when multiple matches are executed concurrently. (The cost of a
single match jumps from ~45ns to ~65ns, and the cost of running matches on
all 12 available CPUs jumps from ~400ns to ~730ns).
## ECMAScript compatibility mode
In this mode the engine provides compatibility with the [regex engine](https://tc39.es/ecma262/multipage/text-processing.html#sec-regexp-regular-expression-objects) described in the ECMAScript specification.
Additionally a Unicode mode is provided which allows parsing of `\u{CodePoint}` syntax that is only when both are provided.

This program reads a file containing function prototypes
(like syscall_aix.go) and generates system call bodies.
The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named err.
* If go func name needs to be different than its libc name,
* or the function is not in libc, name could be specified
* at the end, after "=" sign, like
//sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
This program will generate three files and handle both gc and gccgo implementation:
- zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
- zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
- zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
The generated code looks like this
zsyscall_aix_ppc64.go
func asyscall(...) (n int, err error) {
// Pointer Creation
r1, e1 := callasyscall(...)
// Type Conversion
// Error Handler
return
}
zsyscall_aix_ppc64_gc.go
//go:cgo_import_dynamic libc_asyscall asyscall "libc.a/shr_64.o"
//go:linkname libc_asyscall libc_asyscall
var asyscall syscallFunc
func callasyscall(...) (r1 uintptr, e1 Errno) {
r1, _, e1 = syscall6(uintptr(unsafe.Pointer(&libc_asyscall)), "nb_args", ... )
return
}
zsyscall_aix_ppc64_ggcgo.go
// int asyscall(...)
import "C"
func callasyscall(...) (r1 uintptr, e1 Errno) {
r1 = uintptr(C.asyscall(...))
e1 = syscall.GetErrno()

This program reads a file containing function prototypes

The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named err.
* If go func name needs to be different than its libc name,
* or the function is not in libc, name could be specified
* at the end, after "=" sign, like
//sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
