why "double now=time(0);" and not "time_t now=time(0);" ?
No specific reason.
Looks kinda strange, not sure if it's appropriate to be kept that way in the tutorial. After all, nobody will ask "why time_t?", but some might ask "why double?".
"The source text is not copied." Sometimes 'not' is highlighted, and sometimes
'is'. So what does it try to say after all? That the provided string
argument
must not die before the translated string is fetched?
Already noted there is a small error. std::string is copied no need to keep it, while "char const *" should not die - usual static text.
Makes sense, but in addition to "is *not* copied" statements, a big warning about this needs to be inserted, and make it obvious that it applies to all those involved functions.
And what date-time range does the ICU backend support?
Actually time before BC and long after, virtually limited by range of double.
Good, but needs to be mentioned in the doc.
or a "class bigint" example which uses the Boost.Locale number formatting info for its I/O. Bonus points if they fallback to std facets if corresponding Boost.Locale info is missing from the stream!
Actually it is not quite possible, at least with ICU backend as it supports only double, int32 and int64 types, so it wouldn't be possible to do it.
I'd consider it a severe limitation if that is really impossible. Can't I print my arbitrary big integers in the properly localized way? ICU obviously knows the rules for formatting numbers in the locales it supports, and uses that info to format double, int32, int64. Isn't there a way to query that necessary info from ICU to format numbers outside of it?
It can be done somehow for non-ICU backends that provide std::numpunct,
Are you saying here that a std::numpunct-like facet can't be implemented with the ICU backend?
(it is not enough for ICU case as it is too primitive to handle all required options)
Yes, I understand that std::numpunct interface is not good enough for all locales. What I would like to see in Boost.Locale is a facet much like numpunct but such that it is correct for all locales, and uses ICU to achieve that when that backend is enabled. Of course if that is possible at all?
Thanks, Very good points. Artyom
