Thanks! I could help you with c2nim – feel free to ping me on Discord if you like. I'd like to get the base idf layer automatically imported as well. Most of the current IDF wraps were done using c2nim.
You can look at how I use c2nim in [cimporter](https://github.com/elcritch/cimporter). I started making cimporter to essentially automate running c2nim on these sorts of projects, but never had time to document it. :) Some useful c2nim settings to put into a base project settings using the C pragma syntax. Most of them could be set via CLI options too: #pragma c2nim strict #pragma c2nim importc #pragma c2nim cdecl #pragma c2nim header #pragma c2nim reordercomments // make C comments follow Nim style (mostly) #pragma c2nim mergeDuplicates // merge duplicates that arise after preprocessing #pragma c2nim skipFuncDefines // skip function bodies on inline c functions when using cdecl #pragma c2nim importFuncDefines #pragma c2nim mergeblocks // helps reduce number of times when certain C types can be defined out of order #pragma c2nim stdints // convert modern standard int's like uint8_t, etc #pragma c2nim cppSkipCallOp #pragma c2nim cppSkipConverter #pragma c2nim cppskipconverter #pragma c2nim render nonNep1Imports // useful to enable using nep1 with imports -- otherwise C file names won't match #pragma c2nim render extranewlines #pragma c2nim render reindentlongcomments Run Here's some examples of name-mangling to fix certain imports: #pragma c2nim mangle "'va_list'" "varargs[pointer]" // convert va_list to nim's version #pragma c2nim mangle "'_Bool'" "bool" // how bools end up after preprocessing in clang -- should probably be handled in stdints above #pragma c2nim delete "RCUTILS_ERROR_STATE_FILE_MAX_LENGTH" // delete annoying C arrays or other bits #pragma c2nim delete "'rcutils/stdatomic_helper'" // remove broken c include -> nim import mappings -- unfortunately relies on the '/' in the name Run
