Crystal bindings to ImGui-SFML
Introduction
This library makes it straightforward to
use Dear ImGui (through its crystal-imgui binding)
with SFML (through its CrSFML binding).
See the example.
crystal-imgui-sfml does not attempt to serve as a wrapper for all of these, rather it's just the "glue",
and so both crystal-imgui and CrSFML will still be explicit dependencies of your project.
That said, crystal-imgui-sfml does take over some parts of the installation process from crystal-imgui.
Documentation
Installation
First, install SFML.
Then add to your project's shard.yml file:
dependencies:
crsfml:
github: oprypin/crsfml
imgui:
github: oprypin/crystal-imgui
imgui-sfml:
github: oprypin/crystal-imgui-sfml
Resolve dependencies with Shards:
shards install
During installation this will invoke make
to build the C++ wrappers as object files. SFML headers are expected to be available in the default include path.
Building a project
Try the example from inside the folder of crystal-imgui-sfml:
crystal build examples/simple.cr
Although building the example automatically added the libcimgui.so
library (bundled with the project) to the search path, running it will require that addition to be done manually:
export LD_LIBRARY_PATH="$(pwd)"
./example
For your own project, crystal-imgui-sfml will be in a subdirectory, so adjust this accordingly:
export LD_LIBRARY_PATH="$(pwd)/lib/imgui-sfml"
printf 'require "crsfml"\nrequire "imgui"\nrequire "imgui-sfml"\n' >> my_project.cr
crystal run my_project.cr
Custom SFML location
If SFML's headers and libraries are not in a path where the compiler would look by default, additional steps are needed.
Before building the extensions (make
) you need to configure the include path:
export CXXFLAGS="-I/full/path/to/sfml/include"
export LIBRARY_PATH="/full/path/to/sfml/lib"
make
crystal-imgui-sfml without Shards
It's also possible to use crystal-imgui-sfml outside of Shards, as with any library. One option is to directly create a symbolic link to crystal-imgui-sfml in your project's lib folder.
mkdir lib
ln -s /full/path/to/crsfml lib/crsfml
ln -s /full/path/to/crystal-imgui lib/imgui
ln -s /full/path/to/crystal-imgui-sfml lib/imgui-sfml
Note, though, that the C bindings inside the crystal-imgui-sfml directory must be additionally built using make
.
