LAF: The Lost Application Framework
A library to create Windows, macOS, and Linux applications.
This library is under active development so we don't provide API or ABI compatibility at this moment.
- base: Base functions for any kind of application.
- gfx: Generic graphics classes (rectangle, point, region, etc.)
- ft: FreeType wrapper used by the
freetypelibrary as dependency)
- os: Functions to create windows in your Operating System.
laf can be compiled with two back-ends (
LAF_BACKEND=skia, laf requires a compiled version of the Skia library from branch
aseprite-m96. You can check the aseprite/skia fork which includes a release with pre-built versions, or the check the instructions to compile skia from scratch.
LAF_BACKEND=none, the Pixman library can be used as an alternative implementation of the
gfx::Region class (generally if you're using
laf-os you will link it with Skia, so there is no need for Pixman at all).
To compile laf with Skia as backend you have to specify some variables pointing to a valid compiled version of Skia in your disk. In the following example
/skiadir is the absolute path to a directory where the Skia source code + compiled version is, or just where you've uncompressed a pre-built package of Skia (note that in this case
/skiadir/out/Release-x64 should contain the Skia library files, i.e.
skia.lib on Windows or
libskia.a on other platforms):
git clone https://github.com/aseprite/laf.git cd laf mkdir build cd build cmake -G Ninja \ -DLAF_BACKEND=skia \ -DSKIA_DIR=/skiadir \ -DSKIA_LIBRARY_DIR=/skiadir/out/Release-x64 \ .. ninja ./examples/helloworld
To compile only the library (without examples and tests) you can disable the
cmake -DLAF_WITH_EXAMPLES=OFF -DLAF_WITH_TESTS=OFF ...
You can use
ctest to run all tests:
cd build ninja ctest
LAF_WINDOWS: Compiling on Windows platform
LAF_MACOS: Compiling on macOS platform
LAF_LINUX: Compiling on Linux platform
LAF_SKIA: When we compile with
LAF_BACKEND=skia(Skia library is available)
laf is distributed under the terms of the MIT license.
Some functions in laf depends on third party libraries (you should include these license notices when you distribute your software):
- base::encode/decode_base64 functions use stringencoders by Nick Galbreath (MIT license).
- Tests use the Google Test framework by Google Inc. licensed under a BSD-like license.
- Color spaces,
gfx::Region, and the
laf::oslibrary use code from the Skia library by Google Inc. licensed under a BSD-like license and several other third-party libraries/licenses.
gfx::Regionuses the pixman library if you are not compiling with the Skia backend (e.g. a if you want to create only Command Line utilities that uses the
gfx::Regionclass). Pixman is distributed under the MIT License.
