TextSupport

Colored text & console log support for C++

Requirements

• C++11 or later
• POSIX-compatible environment (Linux, macOS)

Usage

Include

#include "text_support.h"

Named log functions

textSupport::debugMessage("something happened");
textSupport::infoMessage("server started");
textSupport::warningMessage("retrying connection");
textSupport::errorMessage("file not found");
textSupport::fatalMessage("unrecoverable error");

Log with LogLevel enum

Use log() to select the level at call site:

textSupport::log(textSupport::LogLevel::Debug,   "debug message");
textSupport::log(textSupport::LogLevel::Info,    "info message");
textSupport::log(textSupport::LogLevel::Warning, "warning message");
textSupport::log(textSupport::LogLevel::Error,   "error message");
textSupport::log(textSupport::LogLevel::Fatal,   "fatal message");

Adding a new log level

Edit LOG_TABLE in text_support.cpp and add a corresponding entry to the LogLevel enum in text_support.h:

// text_support.h
enum class LogLevel { Debug, Info, Warning, Error, Fatal, Verbose };  // add here

// text_support.cpp
static const LogEntry LOG_TABLE[] = {
    /* Debug   */ { "DBG",     TEXT_SUPPORT_BLUE,    &std::cout },
    /* Info    */ { "INFO",    TEXT_SUPPORT_CYAN,    &std::cout },
    /* Warning */ { "WARN",    TEXT_SUPPORT_YELLOW,  &std::cout },
    /* Error   */ { "ERR",     TEXT_SUPPORT_RED,     &std::cerr },
    /* Fatal   */ { "FATAL",   TEXT_SUPPORT_BOLDRED, &std::cerr },
    /* Verbose */ { "VERBOSE", TEXT_SUPPORT_WHITE,   &std::cout },  // add here
};
