guts

Overview

The gutilities library provides a suite of basic utilities encapsulated within a dedicated namespace, offering a range of functionality for string manipulation, file path operations, and unit conversions.

gutilities namespace:

The gutilities namespace includes essential utility functions such as:

• std::string removeLeadingAndTrailingSpacesFromString(const std::string &input)
  • Removes leading and trailing spaces and tabs from the given string.
• std::vector<std::string> getStringVectorFromString(const std::string &input)
  • Splits a string into a vector of substrings based on spaces, removing leading and trailing spaces from each.
• std::string getFileFromPath(const std::string &path)
  • Extracts the filename from a given file path.
• std::string getDirFromPath(const std::string &path)
  • Extracts the directory path from a given file path.
• double getG4Number(const std::string &v, bool warnIfNotUnit = false)
  • Converts a string representation of a number with optional units to a double, with an optional warning if no units are specified.

Conventions

The gutilities library adheres to several conventions for consistent output formatting and verbosity:

• Color Macros:
  • Utilize macros to format console output with colors, e.g., FRED("my sentence") to print in red.
• Verbosity Levels:
  • Control the level of detail in logging output with verbosity levels ranging from 0 to 3.
• Predefined Strings:
  • Use predefined string macros such as FATALERRORL, GWARNING, POINTITEM, CIRCLEITEM, and SQUAREITEM to standardize message outputs and highlight key information.

Example

The following example demonstrates how to use getStringVectorFromString to split a string into individual words:

#include <iostream>
#include <vector>
#include "gutilities.h" // Ensure this includes the header file where these utilities are defined
 
int main() {
    std::string input = "strings separated by spaces";
    std::vector<std::string> result = gutilities::getStringVectorFromString(input);
 
    for (const auto& word : result) {
        std::cout << word << std::endl;
    }
 
    return 0;
}

Usage:

Run the above code with a string input to see each word printed on a new line:

> example "strings separated by spaces"
strings
separated
by
spaces

Features

The library provides additional utility functions, such as:

• std::string replaceCharInStringWithChars(const std::string &input, const std::string &toReplace, const std::string &replacement)
  • Replaces all occurrences of specified characters in a string with another string.
• bool directoryExists(const std::string &path)
  • Checks if a directory exists at the given path.
• std::vector<std::string> getListOfFilesInDirectory(const std::string &dirName, const std::vector<std::string> &extensions)
  • Retrieves a list of files with specific extensions from a directory.

These utilities are designed to streamline common tasks in software development by providing efficient and easy-to-use functions for string manipulation and file system operations.

Continuous Integration

The GOptions framework is continuously integrated and tested to ensure stability and reliability across updates.
