# Native File Dialog #
A tiny, neat C library that portably invokes native file open, folder select and save dialogs. Write dialog code once and have it pop up native dialogs on all supported platforms. Avoid linking large dependencies like wxWidgets and qt.
Features:
- Lean C API, static library -- no ObjC, no C++, no STL.
- Zlib licensed.
- Consistent UTF-8 support on all platforms.
- Simple universal file filter syntax.
- Paid support available.
- Multiple file selection support.
- 64-bit and 32-bit friendly.
- GCC, Clang, Xcode, Mingw and Visual Studio supported.
- No third party dependencies for building or linking.
- Support for Vista's modern `IFileDialog` on Windows.
- Support for non-deprecated Cocoa APIs on OS X.
- GTK+3 dialog on Linux.
- Tested, works alongside [http://www.libsdl.org](SDL2) on all platforms, for the game developers out there.
# Example Usage #
```C
#include <nfd.h>
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
nfdchar_t *outPath = NULL;
nfdresult_t result = NFD_OpenDialog( NULL, NULL, &outPath );
if ( result == NFD_OKAY ) {
puts("Success!");
puts(outPath);
free(outPath);
}
else if ( result == NFD_CANCEL ) {
puts("User pressed cancel.");
}
else {
printf("Error: %s\n", NFD_GetError() );
}
return 0;
}
```
See [NFD.h](src/include/nfd.h) for more options.

## Changelog ##
The current version is 1.1.1
release | what's new | date
--------|-----------------------------|---------
1.0.0 | initial | oct 2014
1.1.0 | premake5; scons deprecated | aug 2016
1.1.1 | mingw support, build fixes | aug 2016
1.1.2 | test_pickfolder() added | aug 2016
## Building ##
NFD uses [Premake5](https://premake.github.io/download.html) generated Makefiles and IDE project files. The generated project files are checked in under `build/` so you don't have to download and use Premake in most cases.
If you need to run Premake5 directly, further [build documentation](docs/build.md) is available.
Previously, NFD used SCons to build. It still works, but is now deprecated; updates to it are discouraged. Opt to use the native build system where possible.
`nfd.a` will be built for release builds, and `nfd_d.a` will be built for debug builds.
### Makefiles ###
The makefile offers four options, with `release_x64` as the default.
make config=release_x86
make config=release_x64
make config=debug_x86
make config=debug_x64
### Compiling Your Programs ###
1. Add `src/include` to your include search path.
2. Add `nfd.lib` or `nfd_d.lib` to the list of list of static libraries to link against (for release or debug, respectively).
3. Add `build/<debug|release>/<arch>` to the library search path.
On Linux, you must compile and link against GTK+. Recommend use of `pkg-config --cflags --libs gtk+-3.0`.
On Mac OS X, add `AppKit` to the list of frameworks.
On Windows, ensure you are building against `comctl32.lib`.
## Usage ##
See `NFD.h` for API calls. See `tests/*.c` for example code.
After compiling, `build/bin` contains compiled test programs.
## File Filter Syntax ##
There is a form of file filtering in every file dialog API, but no consistent means of supporting it. NFD provides support for filtering files by groups of extensions, providing its own descriptions (where applicable) for the extensions.
A wildcard filter is always added to every dialog.
### Separators ###
- `;` Begin a new filter.
- `,` Add a separate type to the filter.
#### Examples ####
`txt` The default filter is for text files. There is a wildcard option in a dropdown.
`png,jpg;psd` The default filter is for png and jpg files. A second filter is available for psd files. There is a wildcard option in a dropdown.
`NULL` Wildcard only.
## Iterating Over PathSets ##
See [test_opendialogmultiple.c](test/test_opendialogmultiple.c).
# Known Limitations #
I accept quality code patches, or will resolve these and other matters through support. See [submitting pull requests](docs/submitting_pull_requests.md) for details.
- No support for Windows XP's legacy dialogs such as `GetOpenFileName`.
- No support for file filter names -- ex: "Image Files" (*.png, *.jpg). Nameless filters are supported, however.
- On Linux, GTK+ cannot be uninitialized to save memory. Launching a file dialog costs memory. I am open to accepting an alternative `nfd_zenity.c` implementation which uses Zenity and pipes.
