Summary: Appender.clear() functionality or documentation Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2011-06-21 16:12:43 PDT --- This is an enhancement request, or (because I am often mistaken) it's just an enhancement request for the documentation. This program works with DMD 2.053: import std.stdio; void main() { string foo = "abc"; foo ~= 'a'; foo.length = 0; } This other program too runs: import std.array: Appender; void main() { Appender!(char[]) foo; foo.put('a'); foo.clear(); } But this gives an error: temp.d(5): Error: no property 'clear' for type 'Appender!(string)' import std.array: Appender; void main() { Appender!string foo; foo.put('a'); foo.clear(); } Strings are made of immutable chars, but you are allowed to clear (set the length to zero) a string. So I expect Appender to allow the same. If this not a good thing, then I suggest to add to the online docs of the std.array.Appender.clear() method a note that explains it is present (compiled-in) only in certain cases. Because currently I haven't seen a mention of this, and the error message given by the compiler doesn't explain enough. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
