Are there any number formatting routines in Phobos? I couldn't see any, but thought I'd ask. I simply want to get a number back as a string with thousand separators.

If not, I think Win32's GetNumberFormat will do what I want.

Cheers.

There's std.string.format(). It works just like writef() except that it returns
a char[].

Well, of course I knew about string.format. But is there a format pattern that will, for example, return 1500000 as "1,500,000"?

Oops, sorry. I didn't understand that. Apparently there's not, and it seems that C's printf doesn't support that either (AFAICT).

You can use the c-style sprintf to format numbers. Isn't exactly elegant but seems to work. See date.d (in src\phobos\std) for uses.

The "C-style sprintf" you mention *is* the C sprintf, and it doesn't handle thousand separators. I'd already tried it.

This reminds me that one of the gaping holes in Phobos is support for locales. Open std.dateparse to see how bad it is - English day and month names are hard coded! There should be a localisation module that might incorporate numeric formatting (the latter would probably depend on the former, eg for currencies).

Right, I guess I'm looking at rolling my own stuff.

"Right, I guess I'm looking at rolling my own stuff."

I guess this is *the* motto for convenience d-programming until at least version 1.0 ;-)

The ICU project has truly excellent support for this kind of thing, although it is industrial strength ~ can be a bit heavyweight for personal use? They have all kinds of tools for externalizing and migrating/managing I18N concerns, and there's a D wrapper for ICU in the Mango library.

I'm also interested in a lightweight implementation (Mango has a bunch of support functions to make it happen) ~ just haven't got around to hooking up the pieces yet. If ICU is not appropriate for your needs, and you think it's a reasonably idea, we might combine efforts?

Certainly. I'd be more than happy to collaborate on a proper D library for this. I'm going to study some of the existing packages (.NET, Java, ICU, STL) to see what kind of work is required and how it's implemented.

Kris, may I send you the work I've done on this? So far I've got a general class to represent locales on the user's system, several classes for date/time, number and text formatting support, a set of calendars (Gregorian, Japanese, Hijri etc), and some string-related functions.

The following example lists all the calendars supported by a locale.

    Culture[] allCultures = Culture.getCultures(CultureTypes.ALL);
    foreach (Culture culture; allCultures) {
        writefln("Culture: " ~ culture.name ~ " - " ~ culture.displayName);
        Calendar[] calendars = culture.optionalCalendars;
        writefln("Calendars:");
        foreach (Calendar cal; calendars) {
            writefln("\t" ~ cal.toString());
        }
        writefln();
    }

This example prints the days of the week in French:

    Culture culture = new Culture("fr-fr");
    for (DayOfWeek dayOfWeek = DayOfWeek.SUNDAY; dayOfWeek <=
DayOfWeek.SATURDAY; dayOfWeek++) {
        writefln(culture.dateTimeFormat.getDayName(dayOfWeek));
    }

John.
