           Summary: To read a key
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



If not already present, I think it's good to have in std.stdio a portable (on
Windows, Linux, etc) and reliable way to read a single char (key press).

You mean like _getch() or just fgetc()?

This won't work on Unixen unless you also change the terminal mode to cbreak,
because otherwise the terminal doesn't even send the keypress until the end of
line.

But once you start enabling cbreak, then you have to worry about disabling it,
and you start to reinvent ncurses...

We shouldn't close issues unless it's either fixed or is a non-bug. If you
think this issue deserves discussion, please start one on the forums.

Yeah, but this request should have been discussed in the first place by
bearophile. Just opening enhancement requests because one thinks this or that
should be this way doesn't make any sense. If everybody starts to do that, it
will turn to chaos pretty quickly.

I'm not the one who opened this enhancement request. I think the author should
either ask on the forum, or close it. And if there has been a discussion, a
link to it should be given here.

An example of what I'm talking about is 7939.
The guy gives his opinion, without even a debate in the mailing-list. Where
does that come from ?

I have given a generic answer in Issue 7937

I think for normal bug reports, or for very small enhancement requests (that
require only a small and limited amount of code added or changed with no
significant interactions with unrelated user code) discussing it only in
Bugzilla is acceptable.
And I've seen that most people in newsgroups are not interested in very small
things.



 bearophile, are you ok to close ?


I think that generally it's OK to close an enhancement request when it's not
implementable, when it's a bad idea, when there are better ideas, when no one
seems to desire the idea for a lot of time, when it asks for too much work for
too little gain, etc.

In this specific case kennytm and hsteoh have given answers. There is a
Windows-specific way to solve this, and on Unixes it's not immediate to do.

I am not qualified enough to tell if this enhancement request needs to be
closed as WONTFIX.

My feeling is that this bug is merely a small part of something much bigger: we
need a console-interaction library in Phobos (along the lines of conio.h for
windows or ncurses.h for *nixes). I'd prefer to leave this bug open until we
either decide that a console interaction library doesn't belong in Phobos, or
said library is merged and we can say "use this function from std.console to
read a key".
