C wrapping of https://github.com/Nelarius/imnodes

cimnodes

This is a c-api wrapper for imnodes (https://github.com/Nelarius/imnodes) which is a node editor for Dear ImGui (https://github.com/ocornut/imgui)

imnodes is a submodule of this repo. To do generation again in case imnodes is changed, you should update imnodes, make sure that cimgui repository is a sibling folder to this repository folder and execute generator/generator.bat(.sh)

Compilation will need IMNODES_NAMESPACE to be defined as imnodes. With cmake this is done as add_definitions(-DIMNODES_NAMESPACE=imnodes)

cimnodes's Issues

Missing License

It looks like this repository, along with cimguizmo_quat and cimnodes_r, is missing any kind of license declaration. They're probably supposed to have an MIT license file like the other repositories?

And thank you for this work! It's making working with imgui from C and creating bindings for other languages a breeze.

This is so nice!

Is imgui-node-editor happen here?

Help generating dlls

I'm trying to generate cimnodes.dll file to use with another project, but I'm having some trouble doing it.

I saw the makefile in cimgui, and tried making something similar for cimnodes (and cimguizmo, for that matter), but I can't get it to work.
I don't have much experience wit c/c++, so I'm not sure on how to properly solve imgui dependencies.. Should I just include imgui.h and imgui_internals.h in the root folder?

Sorry if this seems simple, but I'm a bit confused as to how to proceed

Why there is no ImNodesContext type in structs_and_enums.json?

namespacing issues?

I'm having the following issues when trying to wrap this api https://github.com/benmkw/imnodes-rs#todo where I'm not yet sure if its my fault (may very well be). Could you tell me if it works for you so that I can be sure its an issue on my side? :D

LuaJIT bindings

Great to see that there are now are c-bindings for this implementation, thank you! Are you planning to create LuaJIT ffi binding for this, by any chance?

namespace: wrong name?

Hi
I'm trying to build shared library with cmake and getting this:

# ...
/home/me/git/cimgui-go/cimgui/cimnodes.cpp: In function ‘void imnodes_ClearLinkSelection_Int(int)’:
/home/mszeptuch/git/cimgui-go/cimgui/cimnodes.cpp:292:12: error: ‘imnodes’ has not been declared
  292 |     return imnodes::ClearLinkSelection(link_id);
      |            ^~~~~~~
# ...

After sed -e s/imnodes/ImNodes/g cimnodes.cpp everything works fine.
