# `dbg(…)`
[![Build Status](https://travis-ci.org/sharkdp/dbg-macro.svg?branch=master)](https://travis-ci.org/sharkdp/dbg-macro) [![Build status](https://ci.appveyor.com/api/projects/status/vmo9rw4te2wifkul/branch/master?svg=true)](https://ci.appveyor.com/project/sharkdp/dbg-macro) [![Try it online](https://img.shields.io/badge/try-online-f34b7d.svg)](https://repl.it/@sharkdp/dbg-macro-demo) [![License: MIT](https://img.shields.io/badge/license-MIT-blue.svg)](dbg.h)
*A macro for `printf`-style debugging fans.*
Debuggers are great. But sometimes you just don't have the time or patience to set
up everything correctly and just want a quick way to inspect some values at runtime.
This projects provides a [single header file](dbg.h) with a `dbg(…)`
macro that can be used in all circumstances where you would typically write
`printf("…", …)` or `std::cout << …`. But it comes with a few extras.
## Examples
``` c++
#include <vector>
#include <dbg.h>
// You can use "dbg(..)" in expressions:
int factorial(int n) {
if (dbg(n <= 1)) {
return dbg(1);
} else {
return dbg(n * factorial(n - 1));
}
}
int main() {
std::string message = "hello";
dbg(message); // [example.cpp:15 (main)] message = "hello" (std::string)
const int a = 2;
const int b = dbg(3 * a) + 1; // [example.cpp:18 (main)] 3 * a = 6 (int)
std::vector<int> numbers{b, 13, 42};
dbg(numbers); // [example.cpp:21 (main)] numbers = {7, 13, 42} (size: 3) (std::vector<int>)
dbg("this line is executed"); // [example.cpp:23 (main)] this line is executed
factorial(4);
return 0;
}
```
The code above produces this output ([try it yourself](https://repl.it/@sharkdp/dbg-macro-demo)):
![dbg(…) macro output](https://i.imgur.com/NHEYk9A.png)
## Features
* Easy to read, colorized output (colors auto-disable when the output is not an interactive terminal)
* Prints file name, line number, function name and the original expression
* Adds type information for the printed-out value
* Specialized pretty-printers for containers, pointers, string literals, enums, `std::optional`, etc.
* Can be used inside expressions (passing through the original value)
* The `dbg.h` header issues a compiler warning when included (so you don't forget to remove it).
* Compatible and tested with C++11, C++14 and C++17.
## Installation
To make this practical, the `dbg.h` header should to be readily available from all kinds of different
places and in all kinds of environments. The quick & dirty way is to actually copy the header file
to `/usr/include` or to clone the repository and symlink `dbg.h` to `/usr/include/dbg.h`.
``` bash
git clone https://github.com/sharkdp/dbg-macro
sudo ln -s $(readlink -f dbg-macro/dbg.h) /usr/include/dbg.h
```
If you don't want to make untracked changes to your filesystem, check below if there is a package for
your operating system or package manager.
### On Arch Linux
You can install [`dbg-macro` from the AUR](https://aur.archlinux.org/packages/dbg-macro/):
``` bash
yay -S dbg-macro
```
### With vcpkg
You can install the [`dbg-macro` port](https://github.com/microsoft/vcpkg/tree/master/ports/dbg-macro) via:
``` bash
vcpkg install dbg-macro
```
## Configuration
* Set the `DBG_MACRO_DISABLE` flag to disable the `dbg(…)` macro (i.e. to make it a no-op).
* Set the `DBG_MACRO_NO_WARNING` flag to disable the *"'dbg.h' header is included in your code base"* warnings.
## Advanced features
### Hexadecimal, octal and binary format
If you want to format integers in hexadecimal, octal or binary representation, you can
simply wrap them in `dbg::hex(…)`, `dbg::oct(…)` or `dbg::bin(…)`:
```c++
const uint32_t secret = 12648430;
dbg(dbg::hex(secret));
```
### Printing type names
`dbg(…)` already prints the type for each value in parenthesis (see screenshot above). But
sometimes you just want to print a type (maybe because you don't have a value for that type).
In this case, you can use the `dbg::type<T>()` helper to pretty-print a given type `T`.
For example:
```c++
template <typename T>
void my_function_template() {
using MyDependentType = typename std::remove_reference<T>::type&&;
dbg(dbg::type<MyDependentType>());
}
```
### Print the current time
To print a timestamp, you can use the `dbg::time()` helper:
```c++
dbg(dbg::time());
```
### Customization
If you want `dbg(…)` to work for your custom datatype, you can simply overload `operator<<` for
`std::ostream&`:
```c++
std::ostream& operator<<(std::ostream& out, const user_defined_type& v) {
out << "…";
return out;
}
```
If you want to modify the type name that is printed by `dbg(…)`, you can add a custom
`get_type_name` overload:
```c++
// Customization point for type information
namespace dbg {
std::string get_type_name(type_tag<bool>) {
return "truth value";
}
}
```
## Development
If you want to contribute to `dbg-macro`, here is how you can build the tests and demos:
Make sure that the submodule(s) are up to date:
```bash
git submodule update --init
```
Then, use the typical `cmake` workflow. Usage of `-DCMAKE_CXX_STANDARD=17` is optional,
but recommended in order to have the largest set of features enabled:
```bash
mkdir build
cd build
cmake .. -DCMAKE_CXX_STANDARD=17
make
```
To run the tests, simply call:
```bash
make test
```
You can find the unit tests in `tests/basic.cpp`.
## Acknowledgement
This project is inspired by Rusts [`dbg!(…)` macro](https://doc.rust-lang.org/std/macro.dbg.html).
