Quickly builds a standalone C++ file and runs the result.
Project description
quickcpp
quickcpp
is a small command-line tool to quickly build and run a single C++ file. Handy for quick experimentations.
Usage
The simplest usage is quickcpp <path/to/some/cppfile>
. When called like this, quickcpp
builds the file (producing a a.out
file) and runs the result.
$ cat examples/helloworld.cpp
#include <iostream>
int main(int argc, char** argv) {
std::cout << "Hello world!\n";
return 0;
}
$ quickcpp examples/helloworld.cpp
- Building ---------------------
c++ examples/helloworld.cpp -Wall -fPIC -std=c++17 -g
- Running ----------------------
Hello world!
Using other libraries
Want to experiment something with QtWidgets? You can specify any installed pkg-config compliant packages using -p <package>
:
$ cat examples/qt.cpp
#include <QApplication>
#include <QMainWindow>
int main(int argc, char** argv) {
QApplication app(argc, argv);
QMainWindow window;
window.setWindowTitle("Hello World");
window.show();
return app.exec();
}
$ quickcpp -p Qt5Widgets examples/qt.cpp
- Building ---------------------
c++ examples/qt.cpp -Wall -fPIC -std=c++17 -g -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/include/x86_64-linux-gnu/qt5/QtWidgets -I/usr/include/x86_64-linux-gnu/qt5 -I/usr/include/x86_64-linux-gnu/qt5/QtGui -I/usr/include/x86_64-linux-gnu/qt5 -I/usr/include/x86_64-linux-gnu/qt5/QtCore -I/usr/include/x86_64-linux-gnu/qt5 -lQt5Widgets -lQt5Gui -lQt5Core
- Running ----------------------
You should see a window like this one:
Any package listed by pkg-config --list-all
can be used by quickcpp
.
Live reload
quickcpp
can use entr to automatically rebuild and rerun your file. Just install entr
and run quickcpp
with the -l
flag.
Installation
The recommended solution is to use pipx:
pipx install quickcpp
But you can also install it with pip
:
pip install --user quickcpp
