https://issues.dlang.org/show_bug.cgi?id=14230 Issue ID: 14230 Summary: [REG2.067b2] std.array.join misses the first element which is empty string Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: regression Priority: P1 Component: Phobos Assignee: nobody@puremagic.com Reporter: jiki@red.email.ne.jp I sometimes use join() in this way. join( [""] ~ ["aa","bb","cc"], " @" ) --> " @aa @bb @cc" This doesn't work properly in D2. This is a regression, probably. ------------------------------------------------------ import std.stdio; import std.array; void main() { string[] ary = ["","aa","bb","cc"]; // leaded by _empty_ element writeln(ary.join(" @")); // In 2.067b2, this outputs "aa @bb @cc" or asserts inside of join() assert(ary.join(" @") == " @aa @bb @cc"); // OK in 2.067b1 and olders } ------------------------------------------------------ -- |
