9421 :: c2nim problem with char[] to UncheckardArray[char]

  Hi,

  I am trying to use c2nim to make a wrapper for the Clap AudioPlugin API.

  I have a line of c code that looks like this:

  static CLAP_CONSTEXPR const char CLAP_EXT_LATENCY[] = "clap.latency";
  Run

  c2nim converts that to:

  var CLAP_EXT_LATENCY*: UncheckedArray[char] = "clap.latency"
  Run

  when I try to compile that though, I get a type mismatch error:

  
   Error: type mismatch: got 'string' for '"clap.latency"' but expected 'UncheckedArray[char]'
  Run

  I have tried casting the string to UncheckedArray and using cstring, but the compiler always complains. I am looking for a solution for this problem, but also a way that I might be able to preprocess the file so that c2nim converts it to something compilable.

  Thanks in advance for any tips!

  I don't think any of the directives mention in the docs could be helpful in your case. Maybe edit the generated file by hand and change it to cstring/string.

  Ok, thanks for taking a look.

  I have a script that does some preprocessing on the .h files and some post processing on the .nim files after the c2nim conversion. I was looking at how nimraylib_now does it, and trying to do something similar.

  I am dealing with this in the post-processing by replacing all occurrences of UncheckedArray[char] with cstring. This seems to do the trick. I thought there might be an alternative way to do this that I might be missing.
