locale() does not support extended locale strings

[dpprdan]

readr cannot parse dates with full month name (january) in Austrian.

library(readr)

German date works fine

parse_date("15. Januar 2015", "%d. %B %Y", locale = locale("de"))
#> [1] "2015-01-15"

Austrian with German locale unsurprisingly not, because German != Austrian month names.

parse_date("15. Jänner 2015", "%d. %B %Y", locale = locale("de"))
#> Warning: 1 parsing failure.
#> row col            expected          actual
#>   1  -- date like %d. %B %Y 15. Jänner 2015
#> [1] NA

locale() does not support extended locale strings.

locale("de_AT")
#> Error: Unknown language 'de_AT'

Because they are not imported from {stringi}.

{stringi} can parse dates in Jänner of course.

stringi::stri_datetime_parse("15. Jänner 2015", "date_long", locale = "de_AT")
#> [1] "2015-01-15 21:01:56 CET"

Could you please rework your reproducible example to use the reprex package ? That makes it easier to see both the input and the output, formatted in such a way that I can easily re-run in a local session.

[dpprdan]

😆 well, the example is a proper reprex, but I guess you mean "gimme one block of code, please".

library(readr)

parse_date("15. Januar 2015", "%d. %B %Y", locale = locale("de"))
#> [1] "2015-01-15"

parse_date("15. Jänner 2015", "%d. %B %Y", locale = locale("de"))
#> Warning: 1 parsing failure.

Re "proper reprex": The whole example was rendered with {reprex} in one go using #' comments for the interleaved prose. See the # add prose, use general markdown formatting reprex() example. reprex_invert() can easily invert the resulting markdown.

The problem is that one cannot extract the markdown source from someone else's GitHub issue (AFAIK?), but only copy the rendered markdown. The latter is missing the code fences to invert.

[hadley]

Ok, I think the minimal reprex here is:

readr::locale("de_AT")
#> Error: Unknown language 'de_AT'

^{Created on 2023-08-01 with reprex v2.0.2}
