https://issues.dlang.org/show_bug.cgi?id=19820 Issue ID: 19820 Summary: Add readfln to std.stdio Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody@puremagic.com Reporter: andre@s-e-a-p.de It is quite hard to use readf for beginners as explained here by Ali and Adam. https://forum.dlang.org/post/agspmmtjrthzxefjbwej@forum.dlang.org Quote from Ali: > The solution is to use readln, which regrettably comes too late in the book: Quote from Adam: > For "%s" with a string argument, it reads ALL of stdin into that string. This means you need to send an end-of-file indicator to the program. ctrl+z on Windows does this, and ctrl+d can on Linux (you might have to hit it twice there; it doesn't technically send end of file, but can be read as it by the program if there is no other input pending in the buffer). > This is quite bizarre for new users, I agree, but it isn't technically invalid. > (my personal feeling though is readf is just a pile of confusion and should > almost never be used. I hate that it is introduced so early in most > tutorials... I'd rather have it in an appendix for special cases only rather > than like page 3.) I would suggest to add a function readfln which solves the issue of readf. readfln executes readln, strip #10 #13 and then executes formattedRead Signature of readfln should be similair to readf https://dlang.org/phobos/std_stdio.html#.readf -- |
