C++ Treasure Box is a service-orienteddevelopment framework andcomponent library based on the Reactor model, aim at make C++ development easy.

• Intelligent hardware, such as: robots (sweepers, commercial service robots), IPC, drones, vehicles, etc.;
• Edge computing components, such as: smart home gateway, IOT edge gateway, etc.;
• Service, such as: SOCK5, Middleware.

See projects:

• cpp-socks5;
• protocal-adapter；

See the Node.js Reactor pattern.
The main thread handles non-blocking IO events in Reactor mode, and cooperates with ThreadPool to perform large calculations and blocking operations.

This mode avoids the annoyance of competing locking in multi-thread mode, and the program is stable and reliable.

All non-business-related work is handled using the built-in main framework. You don't need to care about such trivial things as how to output the log, how to parse the parameters, how to exit the program, and how to write the main function. The main frame is all handled for you.
You only need to derive thetbox::main::Module class, fill in the business code, and then register to the framework.

You can interact with the running service through telnet, make it print internal data, or perform specific actions. This greatly reduces the difficulty of debugging.

1) There are three log sink: stdout + filelog + syslog

• stdout，Output the log to the terminal viastd::cout;
• syslog，Output logs to syslog viasyslog();
• filelog，Write the log to the specified directory, in the format:<PRIFIX>.YYMMDD_HHMMSS.<PID>.log. If the file size exceeds 1M, a new log file will be created. Due to the low efficiency of writing files, the output channel adopts the front-end and back-end modes.

One or more of the three sink can be selected in the startup parameters, and can also be changed through the terminal during operation.

2) Different level different color
The log content includes: level, time (accurate to microseconds), thread number, module name, function name, text, file name, line number.
It is convenient and quick to locate the problem.

3) Flexible log output filter
The log level can be set separately for different modules when the program is running, as follows:

Parameters are provided in JSON format, and any format of running parameters can be passed in, including: integers, decimals, strings, arrays, and combination parameters, meeting almost all parameter passing requirements:

You can use-c your_cfg_file.json to import a configuration file in JSON format at execution time. At the same time, you can also use-s 'xx.yy.zz=vvv' to specify parameters temporarily.
The configuration file in JSON format also supports the include command to include other configuration files when loading.

The child thread entrusts the main thread to execute:

The main thread entrusts the child thread to execute:

When receiving signals: SIGINT, SIGTERM, SIGQUIT, SIGPWR, it will execute the exit process in an orderly manner and release resources. Do a clean exit.

When various program exceptions occur in the program, such as: segment fault, assertion, bus error, exception not caught, etc., the framework will capture and print the complete call stack in the log system. Facing program crashes, no longer look blank. The effect is as follows:

The trace module can record the time and duration of each execution of the marked function, and can export the flame graph for display:

It is a great tool for performance analysis and event blocking problem troubleshooting.

It abandons the cumbersome inheritance and derivation of the traditional state mode, and uses it directly in a combined way, which is simple and convenient. It can also export the state machine diagram to achieve what you see is what you get:

It contains an event-driven behavior tree that can realize sequential, branching, and cyclic action processes in an asynchronous environment, and can export a visual tree diagram in real time:

• Linux series operating system;
• C++11 or above.

make 3rd-party modules RELEASE=1

After completion, the header files and library files are in the .staging directory.
Of course, you can also specify the generation path of header files and library files by specifyingSTAGING_DIR.
like:

make 3rd-party modules RELEASE=1 STAGING_DIR=$HOME/.tbox

After completion, the header files and library files are in the $HOME/.tbox path.

cmake -B buildcmake --build buildcmake --install build

Customize the installation directory by specifyingCMAKE_INSTALL_PREFIX (installed in /usr/local by default):

cmake -B build -DCMAKE_INSTALL_PREFIX=$HOME/.tbox

For details on how to use cpp-tbox to develop your own programs, see the tutorial:
cpp-tbox-tutorials

For example to usefind_package:

cmake_minimum_required(VERSION 3.10)project(tbox-find_package)find_package(tbox COMPONENTS base util alarm event eventx)add_executable(demo main.cpp)target_link_libraries(demo PRIVATE tbox::tbox_base tbox::tbox_util tbox::tbox_alarm tbox::tbox_event tbox::tbox_eventx)

Open the config.mk file, you don’t need to block the modules corresponding toapp_y += xxx, but pay attention to the dependencies between modules.
