make use of most common content locales

closes #714

[Gallaecio]

Hmm… I don’t see how these changes could cause those CI issues 😕

[noviluni]

Hi @mirceachira, @Gallaecio

When running python order_languages.py (As @mirceachira did), we get the order from https://github.com/unicode-cldr/cldr-dates-full.git.

Those errors in the pipelines are happening because CLDR included new languages, and when we try to import the languages from the list of languages ( dateparser.data.language_info.language_order) we can't find them.

I think the new locales are: ccp, ceb, ff-Latn, ia, jv, ku, mi, sd, tg, tt, wo, xh, yue-Hans and yue-Hant.

To create the files for the new languages we should run:

1. python get_cldr_data.py It creates the json files
2. python write_complete_data.py It creates the py files.

However, we should also:

• Update the "supported locales" list in the docs
• Update the avoid_languages list from dateparser.dateparser_scripts. We may need to add some of the new languages or remove some of the old languages from this list.
• Run again the order_languages script as it should reflect the avoid_languages changes.

@mirceachira would you like to work on this? I think you could create a separate PR just running the three scripts (and updating the docs and the avoid_languages list). Once we merge that, we can come here and update this PR and we won't see any issue.

Of course, if you don't want/ you can't I can do it. :)

[mirceachira]

Hey @noviluni for sure I would like to pick that up! Thanks for the detailed tips on it!

[noviluni]

Hi @mirceachira, you will be able run python dateparser_scripts/order_languages.py without errors after merging this: #825

However, I checked what you did and I think this is wrong: https://github.com/scrapinghub/dateparser/pull/805/files#diff-1c848ec911779bd8e06fea6e61745c57c43a463bab86d8ef955f2e29ec8484d0R60 because is generating multiple times the same language in the language_order list in languages_info.py.

On the other hand, I would really appreciate it if you add the date when that list was created in this comment: https://github.com/scrapinghub/dateparser/pull/805/files#diff-1c848ec911779bd8e06fea6e61745c57c43a463bab86d8ef955f2e29ec8484d0R15 to allow us to update in in the future.

Hi @mirceachira, we merged the other PR (#825), could you rebase this PR against master? 🙂

@noviluni simply running the script generates the same problem you mentioned here #805 (comment)

Though there are much fewer tests that required fixing now after #825 . I added the languages accordingly to 'avoid_languages' and fixed the remaining issues.

Please note that I removed this test: 11ba3fb
I'm not sure why the locale order resulted in its failure as well as the failure in the shortname test that I fixed here 876941e

[noviluni]

Hi @mirceachira!

I think we are almost ready to merge this! I'm ok with the changes in the tests, but I would need you to revert the avoid_languages set as suggested and run this: python dateparser_scripts/order_languages.py again.

After that I think we will be able to merge it! 🚀

[noviluni]

I've been opening and closing this PR because we just switched from travis-ci.org to travis-ci.com but the checks show the old travis-ci.org...

Anyway, it seems that all tests passed in travis-ci.com: https://travis-ci.com/github/scrapinghub/dateparser/builds/204189662

[noviluni]

Ok, this is a hard PR to review 😅

You should change the "in" code by "id" in the most_common_locales list too, and after that you should run python dateparser_scripts/write_complete_data.py.

[noviluni]

Hi @mirceachira, thanks for fixing this. As travis-ci stopped working we can't run the tests, so I can't merge this. I started migrating to github actions (WIP PR: https://github.com/scrapinghub/dateparser/pull/859/files) after that we will be able to run the tests and merge this :)

[noviluni]

LGTM!
