Question

[AlexFundorin]

How do I specify the path, where filename.json will be searched for?
Let's say, my c++ project is a DLL, which is in "c:\Plugin" folder. How do I properly access "c:\Plugin\JSON\filename.json" file?

P.S. I'm also wondering, why this warning appears:
../internal/grammar.hpp(140): warning C4003: not enough actual parameters for macro 'max'

Besides that warning, I had a couple of errors about std::min in the library. After changing them to min (I'm using namespace std", those errors are gone.

The library does not manage any search paths, it would be application-specific which search paths to use, from which environment variable to take search paths etc. Usually all file access is relative to the current working directory of the application, i.e. the directory that the application was launched from.

Regarding the warning about max I'm not quite sure what's going on, it doesn't seem to occur anywhere. Which version of the library are you using? And what were the errors regarding std::min()? We do not test with using namespace std because we don't use using like that.

[ColinH]

The issues with min and max are probably because some Windows headers define them as macro. Fortunately there seems to be a simple solution, does this work for you?

[AlexFundorin]

Thanks for the minmax solution. I'll try it later.

Is this value v = parse_file("c:\filename.json"); a valid code, then?
Or value v = parse_file("../filename.json"); this?
and also value v = parse_file("maps\filename.json"); this?

You need to be careful with escape sequences. If you want the filename to be the string c:\filename.json, you need to escape the \, your source code should thus contain "c:\\filename.json" (note: a double backslash).

I've also just committed a change to protect against min/max macros, so the master branch should work even without NOMINMAX.

Thank you!

You're welcome. Please test if your problems are solved (we are not Windows-users ourselves), feel free to re-open this issue if the fix is not working for you.

[AlexFundorin]

I've just replaced the files and it worked without any warnings or errors.
