Using writefln with format specifiers in string

I'm hoping someone has run across this before... I was listing some files in a directory using listdir and then printing out the names using writefln, but the program kept terminating before finishing printing all the contents. I finally figured out it was because in one of the filenames there was a percent sign. So, running the following program on DMD 0.146 will produce a FormatError: # import std.stdio; # void main(char[][] args) { # writefln("AutoDL%3F"); # } How can I get around this? I'm running Windows XP SP2 and I tried the command chcp 65001 to set my console to UTF-8 thinking that might be it, but no go. Then I piped this to a file and lo and behold, the output stopped in the file at the same point on the console. Any help on this would be much appreciated? -Kramer

Perhaps the formatting should allow '%%' to represent a single percent sign? -DavidM

It does. writefln("5%%") outputs "5%." The problem is that he wants to print out arbitrary strings which may have single percent signs, and he doesn't want format() interpreting the percent signs as format specifiers.

It might even make it to the official library. -- Derek (skype: derek.j.parnell) Melbourne, Australia "Down with mediocracy!" 16/02/2006 10:12:47 AM

Yup, I think we should have one such function (write and writeln) in the stdlib.

It might > even make it to the official library. I wrote write, writeln, read, readln but there was no response. (i.e. they didn't make into std.stdio, but to din/dout instead) Will try again. Some day. --anders PS. http://www.digitalmars.com/d/archives/digitalmars/D/15627.html
