Subject: Issue with hide-ifdef and cc-mode
Date: Thu, 27 May 2021 05:06:30 +0200	[thread overview]
Message-ID: <20210527030630.ys6pbkbtqui66iuz@Ergus> (raw)
In-Reply-To: 20210527030630.ys6pbkbtqui66iuz.ref@Ergus

Hi:

I am trying to use hide-ifdef to shadow code like:

#if 0
<code>
#endif

But I found that either

#if 0

or 

#if 1

produces the same result disabling the code inside.

Some slightly more complex examples like:

#define var 1
#ifdef var

doesn't work either (of course).

And when I try hif-evaluate-macro it says things like: 

false <= ‘#if 1’

or 

1 is not defined...

Do we have anything smarter in emacs to shows #if 0 codes? O is there
any extra customization or is there an issue in the package? any idea?

Also when I remove the #if macros from around the code the shadow face
persists.

Any help?
