Cannot get sourcekit-lsp to make sense of CPlaydate

[tjbcg]

Not posting this as an issue because I'm guessing this is just me not knowing enough about swift.

Logs from sourcekit-lsp look like this:

[ERROR][2025-02-14 19:28:10] .../vim/lsp/rpc.lua:770    "rpc"   "/home/tjbc/.bin/sourcekit-lsp-docker"  "stderr"        "<module-includes>:1:10: note: in file included from <module-includes>:1:\n#include \"CPlaydate.h\"\n         ^\n/home/tjbc/Documents/code/Capot/PlaydateKit/Sources/CPlaydate/include/CPlaydate.h:2:10: error: 'pd_api.h' file not found\n#include \"pd_api.h\"\n         ^\n"

q^C⏎   

I've tried all variations of adding -I flags to .sourcekit-lsp/config.json, to no avail. Any idea ?

Hmmm so apparently I didn't try everything. For reference, this is what worked:

{
  "swiftPM": {
    "cCompilerFlags": ["-I", "/path/to/PlaydateSDK/C_API"]
  }
}
