#pragma message w/ #include result in error

[PaltryProgrammer]

Greetings Kind Regards The statements below cause problems for checkheaders. In particular the code threw a std::out_of_range exception. It finds #include 'ed stdafx.h") which of course it does not wish to. I utilize such #pragma messages to aid in debugging. I am not certain but perhaps regex or awk would be better choices. Thank You Kindly

#include "stdafx.h"
#pragma message (#include 'ed stdafx.h")

Thanks! I appreciate you report this issue however I don't actively maintain this tool anymore. If you make a fix in a PR I could merge it.

So how does this #pragma message works.. all inside the () should be treated as some raw string? If there is a ) in the text what happens then?

For information instead of #pragma message you could write #warning ... that is a standard preprocessor command so it's portable.

Greetings Kind Regards I made the change below on line 267 of tokenize.cpp I do not know if it breaks anything. However upon using checkheaders it reported many files not needed which were in fact needed so perhaps I did break it or checkheaders is faulty. As for #pragma message I only know what is found here #pragma message - Best
else
{
// bpw - my initials
std::string skip_this_line;
getline(code, skip_this_line);
lineno++;
// addtoken(line.c_str(), lineno, FileIndex);
// pToken = CurrentToken;
// std::memset(CurrentToken, 0, sizeof(CurrentToken));
}

When I read the help text it sounds to me like msvc expects the parameter to be a message string. i.e.

#pragma message ("#include \"stdafx.h\"")

does it compile your example code and it works as expected?

Greetings Kind Regards According to the example provided on the page link below apparently concatenation occurs. I utilize the form below and compiles w/o error. -Best #pragma message( "#include " __FILE__ ) https://learn.microsoft.com/en-us/cpp/preprocessor/message?view=msvc-170

That looks like valid code:
#pragma message( "#include " __FILE__ )

But I don't think this looks valid: #pragma message (#include 'ed stdafx.h")

Shouldn't it be: #pragma message ("#include 'ed stdafx.h")
