I am using the following alternative to the shipped ifdef header guard.

#ifndef __$FILE_BASE_UPPER$_$FILE_EXT_UPPER$_VER__
#define __$FILE_BASE_UPPER$_$FILE_EXT_UPPER$_VER__ $YEAR$$MONTH_02$$DAY_02$$HOUR_02$
#if (defined(_MSC_VER) && (_MSC_VER >= 1020)) || defined(__MCPP)
#pragma once
#endif /* Check for "#pragma once" support */

$selected$
#endif /* __$FILE_BASE_UPPER$_$FILE_EXT_UPPER$_VER__ */

However, you can probably already tell the issue here. Say I have a header file named foo-bar.h the outcome of the first line when "rendered" will be:

#ifndef __FOO-BAR_H_VER__

... all fine, except for the hyphen in the name. It would be great if there was some kind of filter I could apply to these built-in variables in order to convert hyphens and other characters that would be invalid inside identifiers into underscores. Either some kind of "filter function" or alternative versions of the built-in variables would be great for the purpose.

Thanks.

I had never actually considered this, since nearly all of my file names are also safe identifier names, an old habit I must have picked up somewhere along the line. But trying this, I can use several unhelpful characters in a Windows filename. I have put in a feature request for new versions of the FILE tokens that are identifier character safe:

Thanks. Yeah, there's a whole bunch of them. I guess whenever one uppercases the whole file name using this method the intention is to use it as some kind of identifier or similar. But perhaps there are other reasons I haven't considered :)

In an ancient code base I work on, developers (unhelpfully, I may add) have decided to stick to 8.3 DOS file names as the maximum (only ASCII digits and letters allowed, a dot to separate the extension and the extension itself). Since one of the developers is working on this code for nearly 30 years, he gets to make that call, though.
