lvgl.nim

A wrapper of the Light Versatile Graphic Library (LVGL) for Nim.

Dependencies

• SLD2
• wayland-client?
• xkbcommon?

Installation

Install as usual:

$ nimble install https://github.com/mantielero/lvgl.nim

Status

The wrapper seems to work in Linux. There is no sugar yet, so right now is not very friendly.

You can find some working examples.

Wrapper creation

The wrapper creation is done using nimterop.

It just required:

1. Running the file: src/wrapper/create_wrapper.sh
2. Running the file: src/wrapper/compiles.sh
3. Manually creating the file src/lvgl.nim

TODO

• To reproduce the examples found in the manual.

  • To understand LV_IMG_DECLARE

• How to deal with callbacks?

• Move it to c2nim and individual files.

• Make it more friendly

• What to do with src/components/lv_conf.h?

• Multiplatform?

• To understand better: LV_SIZE_CONTENT (see ex06)

• Export to webassembly:

  • https://forum.lvgl.io/t/feature-phone-ui-in-lvgl-zig-and-webassembly/11987/5
  • https://github.com/lupyuen/pinephone-lvgl-zig

• Using dynamic library or static library

• Importing .png during the compilation process would be great. This would avoid the need for converting them to other formats or even into C code. This could be achieved with: staticRead.

Some notes

I added lvgl as a submodule:

$ git submodule add https://github.com/lvgl/lvgl.git src/components/lvgl
