Code from lua:
https://www.lua.org/source/5.2/lstrlib.c.html
```
static int gmatch_aux (lua_State *L) {

  const char *s = lua_tolstring(L, lua_upvalueindex(1), &ls);
  const char *p = lua_tolstring(L, lua_upvalueindex(2), &lp);
  const char *src;
  ms.L = L;
  ms.matchdepth = MAXCCALLS;
  ms.src_init = s;
  ms.src_end = s+ls;
  ms.p_end = p + lp;
  for (src = s + (size_t)lua_tointeger(L, lua_upvalueindex(3));
       src <= ms.src_end;
       src++) {
    const char *e;
    ms.level = 0;
    lua_assert(ms.matchdepth == MAXCCALLS);
    if ((e = match(&ms, src, p)) != NULL) {
      lua_Integer newstart = e-s;
      if (e == src) newstart++;  /* empty match? go at least one position */
      lua_pushinteger(L, newstart);
      lua_replace(L, lua_upvalueindex(3));
      return push_captures(&ms, src, e);
    }
  }
  return 0;  /* not found */
}
```
On empty match need increase string offset.

<h3>Original repository fork notice:</h3>
<div style="border: 1px dotted red; margin: 1.em 0.5em; font-weight: bold; color: red;">
The original repository has been forked from the original CVS sources of Luaj.
The commit history has been converted to make sure that the original work of
James Roseborough and Ian Farmer is not lost.
Unfortunately, I was not able to contact either James or Ian to hand over
ownership of the Github organization/repo as I have originally intended to.
The community however seems interested enough to continue work on the original
sources and therefore I have decided to make sure that any useful pull requests
that may add some value to the original code base shall be merged in from now
on.<br>

<h3>Garbage Collection And Resources</h3>
LuaJ does not implement the same garbage collector semantics as native Lua. Garbage collection is delegated to the host JVM or CLDC runtime, so <code>collectgarbage()</code> is only a hint and should not be used as a resource-management primitive.
<p>
In particular:
<ul>
<li>Do not rely on garbage collection to close files, sockets, database handles, or other resources.
<li>Always call <code>close()</code> explicitly on files and iterators that own files.
<li><code>io.lines(filename)</code> opens a file implicitly. If iteration is abandoned early, that file may remain open until explicitly collected by the host runtime.
<li>Prefer <code>local f = assert(io.open(...))</code> together with <code>f:lines()</code> and an explicit <code>f:close()</code> when deterministic cleanup matters.
<li>For implicit line iterators that need deterministic early cleanup, use <code>io.linesx(filename)</code> and call <code>iterator:close()</code>.
<li><code>file:linesx()</code> provides the same closable iterator API for already-open files.
<li>On Windows, leaked file handles can prevent rename or delete operations until the process exits.
<li>On JME/CLDC, finalization support may be absent, so explicit close is mandatory.
</ul>
<p>
Short-lived locals may also remain reachable longer than expected because host stack/register reuse is implementation-dependent. If prompt reclamation matters, isolate temporary allocations in functions and clear large references explicitly instead of assuming block exit is enough.
<h3>File Character Encoding</h3>
Source files can be considered encoded in UTF-8 or ISO-8859-1 and results should be as expected,
with literal string contianing quoted characters compiling to the same byte sequences as the input.

/**
* Extension of {@link LuaFunction} which executes lua bytecode.
* <p>
* A {@link LuaClosure} is a combination of a {@link Prototype}
* and a {@link LuaValue} to use as an environment for execution.
* Normally the {@link LuaValue} is a {@link Globals} in which case the environment
* will contain standard lua libraries.
*
* <p>
* There are three main ways {@link LuaClosure} instances are created:
* <ul>
* <li>Construct an instance using {@link #LuaClosure(Prototype, LuaValue)}</li>
* <li>Construct it indirectly by loading a chunk via {@link Globals#load(java.io.Reader, String)}
* <li>Execute the lua bytecode {@link Lua#OP_CLOSURE} as part of bytecode processing
* </ul>
* <p>
* To construct it directly, the {@link Prototype} is typically created via a compiler such as
* {@link org.luaj.vm2.compiler.LuaC}:
* <pre> {@code
* String script = "print( 'hello, world' )";
* InputStream is = new ByteArrayInputStream(script.getBytes());
* Prototype p = LuaC.instance.compile(is, "script");
* LuaValue globals = JsePlatform.standardGlobals();
* LuaClosure f = new LuaClosure(p, globals);
* f.call();
* }</pre>
* <p>
* To construct it indirectly, the {@link Globals#load(java.io.Reader, String)} method may be used:
* <pre> {@code
* Globals globals = JsePlatform.standardGlobals();
* LuaFunction f = globals.load(new StringReader(script), "script");
* LuaClosure c = f.checkclosure(); // This may fail if LuaJC is installed.
* c.call();
* }</pre>
* <p>
* In this example, the "checkclosure()" may fail if direct lua-to-java-bytecode
* compiling using LuaJC is installed, because no LuaClosure is created in that case
* and the value returned is a {@link LuaFunction} but not a {@link LuaClosure}.
* <p>
* Since a {@link LuaClosure} is a {@link LuaFunction} which is a {@link LuaValue},
* all the value operations can be used directly such as:
* <ul>
* <li>{@link LuaValue#call()}</li>
* <li>{@link LuaValue#call(LuaValue)}</li>
* <li>{@link LuaValue#invoke()}</li>
* <li>{@link LuaValue#invoke(Varargs)}</li>
* <li>{@link LuaValue#method(String)}</li>
* <li>{@link LuaValue#method(String,LuaValue)}</li>
* <li>{@link LuaValue#invokemethod(String)}</li>
* <li>{@link LuaValue#invokemethod(String,Varargs)}</li>
* <li> ...</li>
* </ul>
* @see LuaValue
* @see LuaFunction
* @see LuaValue#isclosure()
* @see LuaValue#checkclosure()
* @see LuaValue#optclosure(LuaClosure)
* @see LoadState
* @see Globals#compiler

/**
* Subclass of {@link LuaValue} that implements
* a lua coroutine thread using Java Threads.
* <p>
* A LuaThread is typically created in response to a scripted call to
* {@code coroutine.create()}
* <p>
* The threads must be initialized with the globals, so that
* the global environment may be passed along according to rules of lua.
* This is done via the constructor arguments {@link #LuaThread(Globals)} or
* {@link #LuaThread(Globals, LuaValue)}.
* <p>
* The utility classes {@link org.luaj.vm2.libs.jse.JsePlatform} and
* {@link org.luaj.vm2.libs.jme.JmePlatform}
* see to it that this {@link Globals} are initialized properly.
* <p>
* The behavior of coroutine threads matches closely the behavior
* of C coroutine library. However, because of the use of Java threads
* to manage call state, it is possible to yield from anywhere in luaj.
* <p>
* Each Java thread wakes up at regular intervals and checks a weak reference
* to determine if it can ever be resumed. If not, it throws
* {@link OrphanedThread} which is an {@link java.lang.Error}.
* Applications should not catch {@link OrphanedThread}, because it can break
* the thread safety of luaj. The value controlling the polling interval
* is {@link #thread_orphan_check_interval} and may be set by the user.
* <p>
* There are two main ways to abandon a coroutine. The first is to call
* {@code yield()} from lua, or equivalently {@link Globals#yield(Varargs)},
* and arrange to have it never resumed possibly by values passed to yield.
* The second is to throw {@link OrphanedThread}, which should put the thread
* in a dead state. In either case all references to the thread must be
* dropped, and the garbage collector must run for the thread to be
* garbage collected.
*
