osmanip is a C++ library containing useful tools to manipulate ANSI escape sequences and customize the output stream of your programs. Within this tools you can add colors and styles to the printed strings, change cursor location on the terminal and manage other tools like progress bars and terminal graphics. Using this features may be very useful to adorn your general output stream log or to perform cursor operations.
This is a fully type- and thread-safe library with automatic memory management, with only indispensable dependencies.
It can be installed from source or via vcpkg. See this section for further details.
If you want to mention this software in one of your project / articles, please cite it.
If you use this library please tell me so I can add you to the list of know projects which use this library.

std::cout << osm::feat( osm::sty, "red" ) << "This string is bold!" << osm::feat( osm::rst, "bd/ft" );#include <iostream>
#include <osmanip/manipulators/cursor.hpp>
// Move the cursor right by 2 spaces
std::cout << osm::feat( osm::crs, "right", 2 ) << "Cursor moved!";- Terminal control sequences ( list of all the available terminal control sequences here)
#include <iostream>
#include <osmanip/manipulators/cursor.hpp>
// Output a bell sound
std::cout << osm::feat( osm::tcs, "bell" );#include <iostream>
#include <osmanip/manipulators/printer.hpp>
osm::Decorator my_shell;
// Change std::cout predefined style and color
my_shell.setColor( "green", std::cout );
my_shell.setStyle( "underlined", std::cout );
my_shell( std::cout ) << "The stdout stream has been changed using the Decorator class!" << "\n";
// Change std::cerr predefined style and color
my_shell.setColor( "red", std::cerr );
my_shell.setStyle( "bold italics", std::cerr ); // NOTE: added 2 styles
my_shell( std::cerr ) << "The stderr stream has been changed using the Decorator class!" << "\n";More examples and how-to guides can be found here.
Why choosing this library for ANSI escape sequences manipulation:
- All the functions used to manipulate these sequences are very easy to use and don't require complex code signatures.
- All the most common ANSI sequences can be manipulated.
- Using the Decorator class you can set the style of an output stream at the beginning of your program and keep it unchanged until the end.

#include <osmanip/progressbar/progressbar.hpp>
#include <osmanip/utility/options.hpp>
osm::ProgressBar<int> percentage_bar;
percentage_bar.setMin( 5 );
percentage_bar.setMax ( 46 );
percentage_bar.setStyle( "indicator", "%" );
std::cout << "This is a normal percentage bar: " << "\n";
osm::OPTION( osm::CURSOR::OFF ); // Hide cursor for better output rendering
for ( int i = percentage_bar.getMin(); i < percentage_bar.getMax(); i++ )
{

- Output redirection on file when using progress bars
#include <iostream>
#include <osmanip/progressbar/progress_bar.hpp>
#include <osmanip/redirection/output_redirector.hpp>
osm::OutputRedirector redirector( "output.txt" );
std::cout << "I am printing to the console!\n";
// Redirect output to the file
redirector.begin();
std::cout << "Now I am printing to a file!\n";
osm::ProgressBar<int> my_bar;
// ...
for( int i = my_bar.getMin(); i < my_bar.getMax(); i++ )
{
// Flush the buffer at the start of each loop
redirector.flush();
my_bar.update( i );
}
// Return output to the console
redirector.end();More examples and how-to guides can be found here.
Why choosing this library for progress bars? Some properties:
- Extremely easy to use.
- Compatible with positive or negative variable of any standard type (integer, float, double and others).
- Maximum and minimum values can be set with any value you prefer and the progress bars will be self-built with respect to them.
- Each progress bar feature can be fully customized (messages, style, color, brackets type, time remaining info etc...) regarding to your requirements. You can also choose to use only a progress indicator or a loading bar instead of a complete progress bar.
- It is thread-safe, hence you can use also multiple progress bars simultaneously.
#include <osmanip/manipulators/colsty.hpp>
#include <osmanip/graphics/canvas.hpp>
osm::Canvas canvas(10,10);
canvas.setBackground( '.', osm::feat( osm::col, "bg white" ) + osm::feat( osm::col, "black" ) );
std::cout << "Display an animation in a canvas\n";
for( uint i = 0; i < 10; i++ )
{
canvas.clear();
canvas.put( 0, 2, 'x' );
canvas.put( i, 3, 'A', osm::feat( osm::col, "red" ) );
canvas.put( 5, 0, 'B', osm::feat( osm::col, "blue" ) );
canvas.put( 7, 8, 'Z', osm::feat( osm::col, "bg cyan" ) + osm::feat( osm::col, "black" ) + osm::feat( osm::sty, "bold" ) );
canvas.refresh();
}
#include <functional>
#include <osmanip/manipulators/colsty.hpp>
#include <osmanip/graphics/canvas.hpp>
osm::Plot2DCanvas plot_2d_canvas( 50, 20 );
std::cout << "\n" << "Plot2DCanvas with sin and cos" << "\n";
plot_2d_canvas.setBackground( ' ', osm::feat( osm::col, "bg white" ) );
plot_2d_canvas.enableFrame( true );
plot_2d_canvas.setFrame( osm::FrameStyle::BOX, osm::feat( osm::col, "bg white" ) + osm::feat( osm::col, "black" ) );
plot_2d_canvas.enableFrame( true );
plot_2d_canvas.setFrame( osm::FrameStyle::BOX, osm::feat( osm::col, "bg white" ) + osm::feat( osm::col, "black" ) );
plot_2d_canvas.setScale( 1/3.14, 0.2) ;
for( float i = 0; i < 40; i++ )
{
plot_2d_canvas.setOffset( i/3.14, -2 );
plot_2d_canvas.clear();
plot_2d_canvas.draw( std::function <float( float )>( []( float x ) ->
float{ return std::cos( x ); } ), 'X', osm::feat( osm::col, "bg white" ) + osm::feat( osm::col, "bd red" ) );
plot_2d_canvas.draw( std::function <float( float )>( []( float x ) ->

plot_2d_canvas.refresh();
sleep_for( milliseconds( 100 ) );
}

Why choosing this library for terminal graphics:
- There are very few C++ libraries doing this job, and this is one of them.
- High level of customizability.
- A faster and most comfortable alternative to plot simple functions without the needing of GUI.
// Enable ANSI escape sequences
osm::OPTION( osm::ANSI::ON );
// doing some stuff...
osm::OPTION( osm::ANSI::OFF );// Enable unicode characters
osm::OPTION( osm::UNICODECH::ON );
// doing some stuff...
osm::OPTION( osm::UNICODECH::OFF );More examples and how-to guides can be found here.
Steps to be reproduced:
1) Download one of the releases of the repository
2) Unzip and enter the downloaded repository directory
3) Install and compile the library and its dependencies:
cmake -B buildInstall:
sudo cmake --build build --target install
⚠️ sudois not required on Windows.
Mandatory prerequisites (automatically installed with the script):
- C++17 standard.
- g++ compiler.
- CMake (at least version 3.15).
This is the list of available package managers for osmanip:
Tu use on or more headers of the library:
#include <osmanip/module_folder/module_name.hpp>If you are using the library in a program, add the -losmanip flag to
link source code.
⚠️ : remember also to add-pthreadflag if you want to use some thread-dependent libraries like ** progressbar/multi_progress_bar.hpp** .
To get an installed version of the library:
find_package( osmanip )then, to link it to a target:
target_link_libraries( ${TARGET} osmanip::osmanip )Examples are compiled during the installation procedure.
To run all the examples:
./build/examples/osmanip_manipulators
./build/examples/osmanip_progressbar
./build/examples/osmanip_graphics
./build/examples/osmanip_redirection
⚠️ executables end with.exeif you are on Windows of course.
To compile tests you must build the app in debug mode:
cmake -B build -DCMAKE_BUILD_TYPE=Debug
sudo cmake --build build --target install
⚠️ remember to install the library before launching include tests, or an error will appear.⚠️ if you want to build the library in debug mode, but without compiling tests use also the option-DOSMANIP_TESTS=OFF.
Tests are produced using -Wall -Wextra -pedantic flags. To check them you need some prerequisites:
The doctest package is automatically installed with the installation step. Also the clang-format package is required. The format procedure is performed automatically when compiling.
To launch all tests simultaneously:
./test/all_tests.shEXTRA: to check that only the needed headers are include use this script:
./test/IWYU.sh- Separate progress bar class into multiple files.
- Add an
elapsedTime()method to theProgressBarclass, to show elapsed progress bar time and substitute it to the already existinggetTime()method. - Benchmarking and other studies with respect to similar libraries (already in progress here).
- Add a wiki section for
output_redirector.
