uprintf is a single-header library that allows to print anything in C, intended for debugging and prototyping.
The idea behind single-header libraries is that they're easy to distribute since it's trivial to add them to any project.
By default the header file acts as any header would, i.e. contains declarations (without definitions).
However, by defining a macro the header start to act as a .c file, i.e. contains definitions.
Source files as well as their outputs can be found in examples.
You can also build them yourself using make examples, but note that sqlite takes long to build.
In addition, there are also tests with their outputs in the baselines.

}Installing a single header library is as simple as downloading uprintf.h.
If you have cloned the repository, it can be installed to /usr/local/include by running make install.
This way you should be able to include it without copying the header to every project (since it is a default include path).
- Linux
- Minimum C version is
c99 - Debug information included,
-g2or higher - Have
elf.hin include path
Architectures:
x86_64, amd64
Compilers:
gcc-14.2, gcc-13.3, gcc-12.4
clang-18, clang-17, clang-14
-
Copy or install the library, ensure it is in the include path
-
Pick a single file and define
UPRINTF_IMPLEMENTATIONbefore the include:#define UPRINTF_IMPLEMENTATION #include "uprintf.h"
This will copy library's implementation to be built as a part of this file, so you should choose rarely modified file in order to avoid unnecessary rebuilding.
You can also define options here, see below. -
Add include in other files where you intend to use it:
#include "uprintf.h"
-
Call function.
uprintf(fmt, ...);
fmt- a format string with placeholders(%followed by a letter). Unlike inprintf, you can use anything, e.g. I use%S. Use%%to print%.
For each format specifier there must be a pointer to whatever should be printed in its place (exceptvoid*).
Behavior of the library can be changed by setting options before implementation:
#define OPTION_NAME VALUE
#define UPRINTF_IMPLEMENTATION
#include "uprintf.h"The list of options:
| macro | description | default |
|---|---|---|
UPRINTF_INDENTATION_WIDTH |
The number of spaces to use for indentation | 4 |
UPRINTF_MAX_DEPTH |
How deep can nested structures be. Use a negative value to have no limit | 10 |
UPRINTF_IGNORE_STDIO_FILE |
Should stdio.h's FILE be ignored |
true |
UPRINTF_ARRAY_COMPRESSION_THRESHOLD |
The minimum number of consecutive array values that get compressed(VALUE <repeats X times>). Use a non-positive value to disable it |
4 |
UPRINTF_MAX_STRING_LENGTH |
The max string length after which it will be truncated. Use a non-positive value to have no limit | 200 |
TL;DR: It works by inspecting debugging information of the executable in a debugger-like manner, which allows it to interpret and format passed pointers.
- Read current binary.
- Parse ELF and DWARF.
- Get info about scopes and types.
- Locate scopes from which current call is invoked based on the PC.
- Parse provided arguments.
- Infer types from the parsed arguments.
- Print data using type definition as reference.
Tests take long to complete, so it is highly recommended to set -j NUMBER_OF_CORES.
If you use compiler other than gcc and clang (e.g. clang-18) make sure to specify COMPILERS or edit Makefile.
$ make tests
$ make tests -jNUMBER_OF_CORES
$ make tests COMPILERS=COMPILER_NAME
