How to add a progress bar to a C++ command-line tool using Indicators?

Include indicators/progress_bar.hpp, create a ProgressBar object with options like BarWidth and Fill, then update it with tick() or set_progress(). The README provides basic examples with code snippets for setup.

Indicators vs tqdm for progress bars?

Indicators is a C++ library with thread safety and header-only design, ideal for C++ CLI apps, while tqdm is Python-specific with a rich ecosystem for Python scripts. Indicators offers similar customization but targets different language environments.

Does Indicators work on Windows with Visual Studio?

Yes, it should work as it's platform-agnostic C++, but ensure terminal emulation supports ANSI codes for features like colors. The README includes MinGW instructions, but Visual Studio may require adjustments for console handling.

How to show multiple progress bars at once in Indicators?

Use the MultiProgress class for compile-time fixed bars or DynamicProgress for runtime additions. Examples in the README demonstrate managing concurrent bars with thread-safe updates and dynamic appending.

Can I use custom Unicode characters in Indicators progress bars?

Yes, Indicators handles multi-byte Unicode characters; set fill or lead options to strings like emojis or foreign text, and it respects bar width as shown in the Unicode support section with demos.

How to hide a progress bar after completion in Indicators?

Set the option HideBarWhenComplete to true using set_option() on the progress bar or container, as demonstrated in the DynamicProgress example where bars disappear when done.

indicators — C++ Terminal Progress Bar Library

What is indicators?

Indicators is a header-only C++ library for creating customizable progress indicators like progress bars and spinners in terminal applications. It solves the problem of providing visual feedback for long-running tasks in command-line tools, making them more user-friendly and informative. The library supports various bar styles, multi-threading, and Unicode characters.

Target Audience

C++ developers building command-line applications, tools, or scripts that require visual progress tracking, such as download managers, data processors, or build systems.

Value Proposition

Developers choose Indicators for its simplicity, thread safety, and extensive customization options without external dependencies. Its header-only design and MIT license make it easy to integrate into any C++ project.

Activity Indicators for Modern C++

Use Cases

Best For

Adding progress bars to CLI tools for file downloads or data processing
Creating multi-threaded applications with concurrent progress tracking
Building custom installers or setup wizards with visual feedback
Enhancing scientific computing scripts with progress indicators
Developing build systems that show compilation progress
Implementing interactive command-line interfaces with spinners for async tasks

Not Ideal For

Projects requiring graphical user interface (GUI) progress indicators, such as desktop applications built with frameworks like Qt or GTK.
Non-C++ codebases, as the library is exclusively for C++ and cannot be directly used with languages like Python or Rust where native alternatives exist.
Environments where terminal output is non-interactive or redirected (e.g., logging to files without console support), limiting visual feedback.
Extremely resource-constrained systems where the overhead of thread-safe updates and header-only inclusion might be prohibitive.

Pros & Cons

Pros

Thread-Safe Updates

Safely update progress bars from multiple threads without visual corruption, as highlighted in the thread-safe features and demonstrated in multi-threaded examples like MultiProgress.

Header-Only Integration

Easy to integrate by including headers or using the single-header version, reducing build complexity and dependency management, as noted in the highlights.

Extensive Customization

Offers control over bar width, fill characters, colors, prefixes/postfixes, and supports Unicode, shown in examples with various languages and emojis.

Flexible Progress Management

Supports multiple indicator types (e.g., progress bars, spinners) and management via MultiProgress (compile-time) and DynamicProgress (runtime), as illustrated in the demos.

Cons

Terminal Dependency

Relies on terminal capabilities for features like colors and cursor control, which may fail in basic consoles like Windows CMD or non-interactive shells, limiting portability.

Modern C++ Requirement

Likely depends on C++11 or newer features (e.g., std::thread, constexpr), potentially causing compatibility issues with legacy compilers or codebases.

Build Overhead for Demos

Building sample programs requires CMake and specific flags (e.g., -DINDICATORS_SAMPLES=ON), adding steps for quick testing or integration compared to simpler libraries.
