Quick-FTXUI

A Quick & Easy way to render terminal user interfaces, using FTXUI.

Example

It converts this JSON-like code into a TUI

DoubleBorder Vertical{
    str x
    Red underlined Text("This opens firefox")
    Blue Button{
        "Open firefox",
        System("/usr/bin/firefox"),
        Animated,
        x
    }
    Light separator
    int y = 20
    Yellow Slider {
        "A Slider: ",
        y,
        0,
        100,
        1
    }
    separator
    RoundedBorder Horizontal {
        int z = 1
        int w
        Red Dropdown {
            [ "Zain", "Mahesh", "Alqama", "Vaidic", "Mundane", "Advait", ],
            z
        }
        Cyan Toggle {
            [ "On", "Off", ],
            w
        }
    }

    Dashed separator

    RedLight Button {
        "Exit",
        "Exit",
        Ascii
    }
}

Output

  Example

  

• Colours

  Quick-FTXUI supports FTXUI's 16 color pallete. Support for 256 color pallete coming soon

  Example

  

Note: To run the above examples, build this repository with the steps mentioned here

• Variables

  Used as hooks, so that we can obtain the input given to the Terminal UI. Currently, supports int and str data types

• Embedded scripting supported in C++

  Supports basic scripting functionality, with functions (or hooks) to add & access the quick-ftxui variables. We can also use C++ references to integers and string data types to access the values inside the QF script. See the example given below.

  Full Example

  #include "quick-ftxui.hpp"
  #include <iostream>
  #include <string>
  
  using namespace std;
  using namespace quick_ftxui;
  
  int main() {
      int x = 5;
      string y = "Init value";
      set_int_var("x", &x);
      set_str_var("y", &y);
      string source_code = R"(Border Vertical{
              str z = "init"
              str a
              int o = 0
              Input {
                  "Type something...",
                  y
              }
              RedLight Slider {
                  "Test: ",
                  x,
                  0,
                  100,
                  2
              }
              Magenta Button{
                  "Chrome",
                  System("/usr/bin/google-chrome-stable"),
                  Animated,
                  z
              }
              Green Menu{
                  [ "Physics",  "Maths",  "Chemistry",  "Biology",],
                  VerticalAnimated,
                  o
              }
              Button {
                  "Exit",
                  "Exit"
              }
          })";
  
      parse_qf(source_code);
  
      cout << "Slider value is: " << x << "\n";
      cout << "User input is: " << y << "\n";
      cout << "Option no. selected in Menu is: " << get_int("o") + 1 << "\n";
      cout << "Chrome debug msgs are: " << get_str("z") << "\n";
  }
