CodeMirror: C-like mode

## C-like mode

/* C demo code */ #include <zmq.h> #include <pthread.h> #include <semaphore.h> #include <time.h> #include <stdio.h> #include <fcntl.h> #include <malloc.h> typedef struct { void* arg_socket; zmq_msg_t* arg_msg; char* arg_string; unsigned long arg_len; int arg_int, arg_command; int signal_fd; int pad; void* context; sem_t sem; } acl_zmq_context; #define p(X) (context->arg_##X) void* zmq_thread(void* context_pointer) { acl_zmq_context* context = (acl_zmq_context*)context_pointer; char ok = 'K', err = 'X'; int res; while (1) { while ((res = sem_wait(&context->sem)) == EINTR); if (res) {write(context->signal_fd, &err, 1); goto cleanup;} switch(p(command)) { case 0: goto cleanup; case 1: p(socket) = zmq_socket(context->context, p(int)); break; case 2: p(int) = zmq_close(p(socket)); break; case 3: p(int) = zmq_bind(p(socket), p(string)); break; case 4: p(int) = zmq_connect(p(socket), p(string)); break; case 5: p(int) = zmq_getsockopt(p(socket), p(int), (void*)p(string), &p(len)); break; case 6: p(int) = zmq_setsockopt(p(socket), p(int), (void*)p(string), p(len)); break; case 7: p(int) = zmq_send(p(socket), p(msg), p(int)); break; case 8: p(int) = zmq_recv(p(socket), p(msg), p(int)); break; case 9: p(int) = zmq_poll(p(socket), p(int), p(len)); break; } p(command) = errno; write(context->signal_fd, &ok, 1); } cleanup: close(context->signal_fd); free(context_pointer); return 0; } void* zmq_thread_init(void* zmq_context, int signal_fd) { acl_zmq_context* context = malloc(sizeof(acl_zmq_context)); pthread_t thread; context->context = zmq_context; context->signal_fd = signal_fd; sem_init(&context->sem, 1, 0); pthread_create(&thread, 0, &zmq_thread, context); pthread_detach(thread); return context; }

## C++ example

#include <iostream> #include "mystuff/util.h" namespace { enum Enum { VAL1, VAL2, VAL3 }; char32_t unicode_string = U"\U0010FFFF"; string raw_string = R"delim(anything you want)delim"; int Helper(const MyType& param) { return 0; } } // namespace class ForwardDec; template <class T, class V> class Class : public BaseClass { const MyType<T, V> member_; public: const MyType<T, V>& Method() const { return member_; } void Method2(MyType<T, V>* value); } template <class T, class V> void Class::Method2(MyType<T, V>* value) { std::out << 1 >> method(); value->Method3(member_); member_ = value; }

## Objective-C example

/* This is a longer comment That spans two lines */ #import <Test/Test.h> @implementation YourAppDelegate // This is a one-line comment - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ char myString[] = "This is a C character array"; int test = 5; return YES; }

## Java example

import com.demo.util.MyType; import com.demo.util.MyInterface; public enum Enum { VAL1, VAL2, VAL3 } public class Class<T, V> implements MyInterface { public static final MyType<T, V> member; private class InnerClass { public int zero() { return 0; } } @Override public MyType method() { return member; } public void method2(MyType<T, V> value) { method(); value.method3(); member = value; } }

## Scala example

object FilterTest extends App { def filter(xs: List[Int], threshold: Int) = { def process(ys: List[Int]): List[Int] = if (ys.isEmpty) ys else if (ys.head < threshold) ys.head :: process(ys.tail) else process(ys.tail) process(xs) } println(filter(List(1, 9, 2, 8, 3, 7, 4), 5)) }

## Kotlin mode

package org.wasabi.http import java.util.concurrent.Executors import java.net.InetSocketAddress import org.wasabi.app.AppConfiguration import io.netty.bootstrap.ServerBootstrap import io.netty.channel.nio.NioEventLoopGroup import io.netty.channel.socket.nio.NioServerSocketChannel import org.wasabi.app.AppServer public class HttpServer(private val appServer: AppServer) { val bootstrap: ServerBootstrap val primaryGroup: NioEventLoopGroup val workerGroup: NioEventLoopGroup init { // Define worker groups primaryGroup = NioEventLoopGroup() workerGroup = NioEventLoopGroup() // Initialize bootstrap of server bootstrap = ServerBootstrap() bootstrap.group(primaryGroup, workerGroup) bootstrap.channel(javaClass<NioServerSocketChannel>()) bootstrap.childHandler(NettyPipelineInitializer(appServer)) } public fun start(wait: Boolean = true) { val channel = bootstrap.bind(appServer.configuration.port)?.sync()?.channel() if (wait) { channel?.closeFuture()?.sync() } } public fun stop() { // Shutdown all event loops primaryGroup.shutdownGracefully() workerGroup.shutdownGracefully() // Wait till all threads are terminated primaryGroup.terminationFuture().sync() workerGroup.terminationFuture().sync() } }

## Ceylon mode

"Produces the [[stream|Iterable]] that results from repeated application of the given [[function|next]] to the given [[first]] element of the stream, until the function first returns [[finished]]. If the given function never returns `finished`, the resulting stream is infinite. For example: loop(0)(2.plus).takeWhile(10.largerThan) produces the stream `{ 0, 2, 4, 6, 8 }`." tagged("Streams") shared {Element+} loop<Element>( "The first element of the resulting stream." Element first)( "The function that produces the next element of the stream, given the current element. The function may return [[finished]] to indicate the end of the stream." Element|Finished next(Element element)) => let (start = first) object satisfies {Element+} { first => start; empty => false; function nextElement(Element element) => next(element); iterator() => object satisfies Iterator<Element> { variable Element|Finished current = start; shared actual Element|Finished next() { if (!is Finished result = current) { current = nextElement(result); return result; } else { return finished; } } }; };

Simple mode that tries to handle C-like languages as well as it can. Takes two configuration parameters: `keywords`, an object whose property names are the keywords in the language, and `useCPP`, which determines whether C preprocessor directives are recognized.
