Modules
System
The System
module provides a set of classes and functions to handle system-level operations like pipes, processes, and system variables.
Example: Process
Include the necessary headers in your project and link against the StormByte
library:
#include <StormByte/system/process.hxx>
#include <iostream>
using namespace StormByte::System;
int main() {
std::vector<std::string> args = {"-l", "-a"};
Process grep(
"/bin/grep", {
"main.cpp"});
ls >> grep;
grep.wait();
std::string output;
grep >> output;
std::cout << output << std::endl;
return 0;
}
Process class for running external programs They will run immediately after creation.
Definition process.hxx:37
Example: Variable
#include <StormByte/system/variable.hxx>
#include <iostream>
int main() {
std::cout << "Home path: " << path << std::endl;
return 0;
}
static std::string Expand(const std::string &str)
Thank you for the correction! Let's update the example to access comments through their position or using an iterator.
Config
Overview
The Config
module of StormByte provides a flexible and human-readable way to manage configuration files. It supports initialization from any std::istream
, setting pre and post read hooks using std::function
, handling different data types (string, int, double, single and multiline comments, and containers such as lists and groups), and managing operation modes when items already exist before addition.
Initialization from <tt>std::istream</tt>
You can initialize the configuration from any std::istream
, including std::fstream
, std::cin
, or even another Config
object.
Example
#include <StormByte/config/config.hxx>
#include <fstream>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
Config config2;
std::cin >> config2;
Config config3;
config2 >> config3;
return 0;
}
Hooks: Pre and Post Read
You can set pre and post read hooks using std::function
. These hooks allow you to perform actions before and after reading the configuration, with the Config
object passed as a reference argument.
Example
#include <StormByte/config/config.hxx>
#include <iostream>
#include <functional>
using namespace StormByte::Config;
void pre_read_hook(Config& config) {
std::cout << "Pre-read hook executed. Current config has " << config.Size() << " items." << std::endl;
}
void post_read_hook(Config& config) {
std::cout << "Post-read hook executed. Current config has " << config.Size() << " items." << std::endl;
}
int main() {
Config config;
config.SetPreReadHook(pre_read_hook);
config.SetPostReadHook(post_read_hook);
std::ifstream file("config.cfg");
file >> config;
file.close();
return 0;
}
Operation Modes for Existing Items
You can set the operation mode when an item already exists before adding a new one. Operation modes can include replace, ignore, or throw an exception (the default).
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
config.SetOperationMode(Config::OperationMode::Replace);
std::ifstream file("config.cfg");
file >> config;
file.close();
return 0;
}
Data Types
The configuration supports various data types, including strings, integers, doubles, comments (single and multiline), and containers (lists and groups).
Strings
username = "example_user"
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
const Item& username = config["username"];
std::cout << "Username: " << username.Value<std::string>() << std::endl;
return 0;
}
Integers
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
const Item& timeout = config["timeout"];
std::cout << "Timeout: " << timeout.Value<int>() << std::endl;
return 0;
}
Doubles
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
const Item& feature_timeout = config["feature_timeout"];
std::cout << "Feature Timeout: " << feature_timeout.Value<double>() << std::endl;
return 0;
}
Comments
Single-line comments start with #
, and multiline comments are enclosed between /*
and */
.
# This is a single-line comment
/**
* This is a multiline comment
*/
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
for (std::size_t i = 0; i < config.Size(); ++i) {
const Item& item = config[i];
if (item.Type() == Item::Type::Comment) {
std::cout << "Comment: " << item.Value<Comment>() << std::endl;
}
}
return 0;
}
Containers: Lists
Lists are sequences of values enclosed in square brackets []
separated by spaces and can contain any other item (including nested lists and groups).
favorite_numbers = [3 14 42 "pi constant"]
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
const List& favorite_numbers = config["favorite_numbers"].Value<List>();
std::cout << "Favorite Numbers: ";
for (const auto& number : favorite_numbers) {
if (number.GetType() == Item::Type::Integer)
std::cout << number.Value<int>() << " ";
else
std::cout << number.Value<std::string> << number;
}
std::cout << std::endl;
return 0;
}
Containers: Groups
Groups are nested configurations that can contain other key-value pairs, groups, or lists.
settings = {
username = "example_user"
timeout = 30
}
Example
#include <StormByte/config/config.hxx>
#include <iostream>
using namespace StormByte::Config;
int main() {
Config config;
std::ifstream file("config.cfg");
file >> config;
file.close();
const Item& username = config["settings/username"];
const Item& timeout = config["settings/timeout"];
std::cout << "Username: " << username.Value<std::string>() << std::endl;
std::cout << "Timeout: " << timeout.Value<int>() << std::endl;
return 0;
}
This expanded section covers all requested features for the configuration file management in your library, with the correct handling and retrieval of comments. If there's anything specific you'd like to adjust or add, let me know!
Log
The Log
module provides a comprehensive logging framework with support for different logging levels and outputs.
Example: Log
#include <StormByte/log/logger.hxx>
#include <iostream>
using namespace StormByte::Log;
int main() {
Logger logger(std::cout, StormByte::Log::Level::Error);
logger << Level::Info << "This is an info message";
logger << Level::Error << "This is an error message";
return 0;
}
Database
The Database
module provides support for SQLite, an embedded SQL database engine. It includes classes for managing database connections, prepared statements, and result rows.
Example: Database
#include <StormByte/database/sqlite/sqlite3.hxx>
#include <memory>
#include <iostream>
class MyDatabase : public StormByte::Database::SQLite::SQLite3 {
public:
MyDatabase(const std::filesystem::path& dbfile) : SQLite3(dbfile) {
init_database();
}
void print_all_users() {
auto stmt = prepare_select_all_users();
while (auto row = stmt->Step()) {
std::cout << "ID: " << row->At(0)->Value<int>() << " Name: " << row->At(1)->Value<std::string>() << std::endl;
}
}
protected:
void post_init_action() noexcept override {
try {
silent_query("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT NOT NULL)");
} catch (const StormByte::Database::SQLite::Exception& e) {
std::cerr << "Database initialization error: " << e.what() << std::endl;
}
}
std::shared_ptr<StormByte::Database::SQLite::PreparedSTMT> prepare_select_all_users() {
return prepare_sentence("select_all_users", "SELECT * FROM users");
}
};
int main() {
MyDatabase db("/path/to/database.db");
db.print_all_users();
return 0;
}
