• gh-130665: Only apply locale to calendar CLI via --locale and not LANG env var #130676

[hugovk]

Thanks for the report. Specifically caused by PR #129625.

Before, we'd get the month/day names in English, despite the env var:

❯ LANG=uk_UA.UTF-8 python3.13 -m calendar 2025 2
   February 2025
Mo Tu We Th Fr Sa Su
                1  2
 3  4  5  6  7  8  9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28

It's because options.locale is not set (via --locale), so we used cal = TextCalendar().

TextCalendar is a subclass of the base Calendar class.

Now, we get this:

❯ LANG=uk_UA.UTF-8 ./python.exe -m calendar 2025 2
    лютого 2025
пн вт ср чт пт сб нд
                1  2
 3  4  5  6  7  8  9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28

This is because options.locale is still not set, we use the new cal = _CLIDemoCalendar(highlight_day=today).

However, _CLIDemoCalendar is a subclass of LocaleTextCalendar (itself a subclass of TextCalendar).

Before, we only used LocaleTextCalendar when options.locale is set.

But now LocaleTextCalendar sets the locale from the env var, and we get local month/day names.
