Hi!, What's the equivalent of the C isatty() in D? I grepped isatty in all sources files and did not find it. Also, i would like to know if anyone compiled the Pavel's stream.d library with a recent V1 D compiler. This library seems to allow reading utf-8 from a windows console. With dmd 1.043, it's very easy to write utf string to console. But, how do we readln from the console ? Thanks...

You can use any C function from D. Phobos does not have a terribly good set of Posix headers, so you'll have to declare it yourself: extern(C) int isatty(int); And you should be able to use it. You shouldn't get any linking errors, at least I don't think.Also, i would like to know if anyone compiled the Pavel's stream.d library with a recent V1 D compiler.You mean std.stream? That's been part of Phobos .. well, forever. At least 5 years anyway.This library seems to allow reading utf-8 from a windows console. With dmd 1.043, it's very easy to write utf string to console. But, how do we readln from the console ?std.stdio.readln.

You shouldn't get any linking errors, at least I don't think.It worked fine.no link error. isatty is sometimes used like this: isatty(fileno(fp)) So i used fileno(), whis is declared in std.c.stdio. but i got a linking error: _fileno not found. I tried two other function in std.c.stdio to see if this was causes by some other factor i am not awared of. clearerr() and rewind() works just fine. So may be there is a problem with fileno() ??You mean std.stream? That's been part of Phobos .. well, forever. At least 5 years anyway.No, i mean the stream.d that comes in stream.zip from the Pavel's site: http://int19h.tamb.ru/files/stream.zip His stream library seems different. as, it have functions to read Unicode strings from the console. I tried to compile it with dmd 1.043 but there are many errors.This library seems to allow reading utf-8 from a windows console. With dmd 1.043, it's very easy to write utf string to console. But, how do we readln from the console ?I know that function. But it allows to read char[] arrays only. (if i read well the declarations). How do i read wchar[] arrays from the console with it ? As i said, it's real easy to write unicode strings to the console. But, it seems a lot less easier to read unicode from the console. Am i right ?std.stdio.readln

That zip is absolutely ancient. It's no surprise it doesn't compile.You mean std.stream? =A0That's been part of Phobos .. well, forever.

It's just UTF-8.How do i read wchar[] arrays from the console with it ?Use std.cstream.din.readLineW() if you want a wchar[] so badly.

So may be there is a problem with fileno() ??As posted in recent thread "How-to: input/output "Japanese Caracters", all you have to do with Unicode is simply to use readln and writeln.
