icu_date gives an error message attempt to index a number value


I want to use the icu_date library, but when I try to insert a value, an error appears

icu_date = require("icu-date")
format_date = icu_date.formats.iso8601()
end_time = icu_date.now()
1602586287098 - print value
end_time:set_millis(1602461532000)
error: '[string "return end_time:set_millis(1602461532000)"]:1: attempt to index global ''end_time'' (a number value)'

Maybe there are not enough libraries?


Solution

  • Seems you need to use icu_date.new() (not now) to create new instance. Then you can use it in the way you want:

    icu_date = require("icu-date")
    format_date = icu_date.formats.iso8601()
    end_time = icu_date.new()
    end_time:set_millis(1602461532000)
    tarantool> end_time:format(format_date)
    ---
    - 2020-10-12T00:12:12.000Z
    ...
    

    icu_date.now() returns current time. That's actually a number value.

    tarantool> icu_date = require('icu-date')
    ---
    ...
    
    tarantool> icu_date.now()
    ---
    - 1602597687320
