Transpilation to Golang

[Konstantin8105]

Hello! If you want transpile from C to Golang, then you can use my project c4go. Just for example, I take for example folder plan9port/src/cmd/troff. Run c4go transpile -clang-flag="-I../../../include/" n*.c dw*.c t*.c. As result we have Go file.

Some notes about transpilation:

• not every C code can be transpiled to Go. For example, function getch from plan9port/src/cmd/troff/n1.c:409 have switch with goto between case.
• pointer arithmetic look is not good in Go. For example this function:

  // twdone - transpiled function from  $GOPATH/src/templorary/plan9port/src/cmd/troff/n10.c:267
  func twdone() {
  if noarch.NotInt(TROFF) != 0 && t.twrest != nil {
      obufp = obuf
      func() int {
          if func() []byte {
              obufp = (*(*[1000000000]byte)(unsafe.Pointer(uintptr(unsafe.Pointer(&obufp[0])) + (uintptr)(noarch.Sprintf(obufp, []byte("%s\x00"), t.twrest))*unsafe.Sizeof(obufp[0]))))[:]
              return obufp
          }() > (*(*[1000000000]byte)(unsafe.Pointer(uintptr(unsafe.Pointer(&obuf[0])) + (uintptr)(8192)*unsafe.Sizeof(obuf[0]))))[:] {
              return flusho()
          }
          return 1
      }()
      flusho()
      if pipeflg != 0 {
          pclose(ptid)
      }
      restore_tty()
  }
  }

  So, if you need help, then please clarify. Fell free close that issue.

Thanks for the heads up. For now we'll keep things in C but I am happy to hear about c4go. Best, Russ.
