A multi-platform solution in lua , you can develop your app, IOS or android app with this tool, truely write once , use everywhere. Notice , you can only use Luakit to write business logic code including network, db orm, multithread model, but not UI code, Luakit do not provide api for UI development.
I will say Luakit is the most effective tool to develop apps on more than one platform. Here are some reasons
-
Cross platform, truely write once use everywhere, this feature is very attractive, if you have experienced multi-platform development , cross platform architecture will be very impressive for you. It can promote efficiency largely.
-
Dynamic and flexible, write business logic code in lua , you can release your code anytime, truely agile development.
-
Forget the annoying memory management, lua support automatic garbage collection. Lua has closures, also known as blocks. These features make Luakit much more effective than other c++ cross platform solution.
For some simple Luakit apps, check out the source folder.
Multithreading
We provide some powerful multi-threading api in lua , you can see ThreadTest in Android Demo folder and IOS Demo folder. Notice , It is not only thread safety multithreading model, but also really competition multithreading model. It is the unique solution to perform competition multithreading in lua or js.
Create thread , demo code
-- Parma1 is the thread type ,there are five types of thread you can create.
-- BusinessThreadUI
-- BusinessThreadDB
-- BusinessThreadLOGIC
-- BusinessThreadFILE
-- BusinessThreadIO
-- Param2 is the thread name
-- Result is new threadId which is the token you should hold to do further action
local newThreadId = lua.thread.createThread(BusinessThreadLOGIC,"newThread")Perform method on a specified thread async, demo code
-- Parma1 is the threadId for which you want to perform method
-- Parma2 is the modelName
-- Parma3 is the methodName
-- The result is just like you run the below code on a specified thread async
-- require(modelName).methodName("params", 1.1, {1,2,3}, function (p)
-- end)
lua.thread.postToThread(threadId,modelName,methodName,"params", 1.1, {1,2,3}, function (p)
-- do something here
end)Perform method on a specified thread sync, demo code
-- Parma1 is the threadId for which you want to perform method
-- Parma2 is the modelName
-- Parma3 is the methodName
-- The result is just like you run the below code on a specified thread sync
-- local result = require(modelName).methodName("params", 1.1, {1,2,3}, function (p)
-- end)
local result = lua.thread.postToThreadSync(threadId,modelName,methodName,"params", 1.1, {1,2,3}, function (p)
-- do something here
end)ORM
Luakit provide a orm solution which has below features
- Object-oriented interfaces
- Automatically create and update table schemas.
- Has internal cache
- Timing auto transaction
- Thread safe
Define your model, demo code
-- Add the define table to dbData.lua
-- Luakit provide 7 colum types
-- IntegerField to sqlite integer
-- RealField to sqlite real
-- BlobField to sqlite blob
-- CharField to sqlite varchar
-- TextField to sqlite text
-- BooleandField to sqlite bool
-- DateTimeField to sqlite integer
user = {
__dbname__ = "test.db",
__tablename__ = "user",
username = {"CharField",{max_length = 100, unique = true, primary_key = true}},
password = {"CharField",{max_length = 50, unique = true}},
age = {"IntegerField",{null = true}},
job = {"CharField",{max_length = 50, null = true}},
des = {"TextField",{null = true}},
time_create = {"DateTimeField",{null = true}}
},
-- when you use, you can do just like below
local Table = require('orm.class.table')
local userTable = Table("user")Insert data, demo code
local userTable = Table("user")
local user = userTable({
username = "user1",
password = "abc",
time_create = os.time()
})
user:save()Update data, demo code
local userTable = Table("user")
local user = userTable.get:primaryKey({"user1"}):first()
user.password = "efg"
user.time_create = os.time()
user:save()Delete data, demo code
local userTable = Table("user")
local user = userTable.get:primaryKey({"user1"}):first()
user:delete()Batch update, demo code
local userTable = Table("user")
userTable.get:where({age__gt = 40}):update({age = 45})Batch Delete, demo code
local userTable = Table("user")
userTable.get:where({age__gt = 40}):delete()Select, demo code
local userTable = Table("user")
local users = userTable.get:all()
print("select all -----------")
local user = userTable.get:first()
print("select first -----------")
users = userTable.get:limit(3):offset(2):all()
print("select limit offset -----------")
users = userTable.get:order_by({desc('age'), asc('username')}):all()
print("select order_by -----------")
users = userTable.get:where({ age__lt = 30,
age__lte = 30,
age__gt = 10,
age__gte = 10,
username__in = {"first", "second", "creator"},
password__notin = {"testpasswd", "new", "hello"},
username__null = false
}):all()
print("select where -----------")
users = userTable.get:where({"scrt_tw",30},"password = ? AND age < ?"):all()
print("select where customs -----------")
users = userTable.get:primaryKey({"first","randomusername"}):all()
print("select primaryKey -----------")Join, demo code
local userTable = Table("user")
local newsTable = Table("news")
local user_group = newsTable.get:join(userTable):all()
print("join foreign_key")
user_group = newsTable.get:join(userTable,"news.create_user_id = user.username AND user.age < ?", {20}):all()
print("join where ")
user_group = newsTable.get:join(userTable,nil,nil,nil,{create_user_id = "username", title = "username"}):all()
print("join matchColumns ")Http request
Luakit provide a http request interface, it has an internal dispatcher which contains a FIFO queue , here is the source code, demo code
-- url , the request url
-- isPost, boolean value represent post or get
-- uploadContent, string value represent the post data
-- uploadPath, string value represent the file path to post
-- downloadPath, string value to tell where to save the response
-- headers, tables to tell the http header
-- socketWatcherTimeout, int value represent the socketTimeout
-- onResponse, function value represent the response callback
-- onProgress, function value represent the onProgress callback
lua.http.request({ url = "http://tj.nineton.cn/Heart/index/all?city=CHSH000000",
onResponse = function (response)
end})Async socket
Luakit provide a non-blocking interface for socket connect , demo code
local socket = lua.asyncSocket.create("127.0.0.1",4001)
socket.connectCallback = function (rv)
if rv >= 0 then
print("Connected")
socket:read()
end
end
socket.readCallback = function (str)
print(str)
timer = lua.timer.createTimer(0)
timer:start(2000,function ()
socket:write(str)
end)
socket:read()
end
socket.writeCallback = function (rv)
print("write" .. rv)
end
socket:connect()Notification
Luakit provide a notification system by which notifications can transfer through the lua environment and native environment
Lua register and post notification, demo code
lua.notification.createListener(function (l)
local listener = l
listener:AddObserver(3,
function (data)
print("lua Observer")
if data then
for k,v in pairs(data) do
print("lua Observer"..k..v)
end
end
end
)
end);
lua.notification.postNotification(3,
{
lua1 = "lua123",
lua2 = "lua234"
})Android register and post notification,, demo code
LuaNotificationListener listener = new LuaNotificationListener();
INotificationObserver observer = new INotificationObserver() {
@Override
public void onObserve(int type, Object info) {
HashMap<String, Integer> map = (HashMap<String, Integer>)info;
for (Map.Entry<String, Integer> entry : map.entrySet()) {
Log.i("business", "android onObserve");
Log.i("business", entry.getKey());
Log.i("business",""+entry.getValue());
}
}
};
listener.addObserver(3, observer);
HashMap<String, Integer> map = new HashMap<String, Integer>();
map.put("row", new Integer(2));
NotificationHelper.postNotification(3, map);IOS register and post notification,, demo code
_notification_observer.reset(new NotificationProxyObserver(self));
_notification_observer->AddObserver(3);
- (void)onNotification:(int)type data:(id)data
{
NSLog(@"object-c onNotification type = %d data = %@", type , data);
}
post_notification(3, @{@"row":@(2)});Any questions? Send an email to williamwen1986@gmail.com
