Add RTL layout support and Arabic localization

[Rami-Sabbagh]

Hello 👋

I've put some effort and added RTL support to the awesome theme you've have made.
And added Arabic localization.

I had to use a tailwind package to achieve that. And I did update the cached prebuilt css.

I've made that so I could use it for my own blog. And thought why not share it with everyone.

Please tell me what are your thoughts.

A little note on defining RTL languages in languages.yaml: a languageDirection: rtl property should be added.

For example in Arabic:

ar:
  languageCode: ar
  languageName: العربية
  languageDirection: rtl
  contentDir: content/ar
  title: مدوّنة

Hi @Rami-Sabbagh,

Thank you so much for adding this awesome feature, it is quite necessary for Eureka to have this. Since I have no experiences in RTL languages, do you have a RTL example with Eureka and its source code? This may help me to review this PR. Thanks again for your contribution ;-)

There's my personal blog, but the posts have not been translated to Arabic yet.
AR • EN • source-code

I've done some modifications today to add singular & plural formatting support for the reading time metadata of each post.
By following the hugo docs.

Updated all the existing localizations to use the new property, but I'm afraid this might introduce backwards incompatible update. (Users will have to update their localization files).

Hi @Rami-Sabbagh,

Thanks for your contribution! I just have one comment as above, feel free to talk to me if you have any thoughts.

Hi @Rami-Sabbagh,

Just one little comment about the one in i18n. And if you are cool with the whole pr, I can merge it later

Hello @wangchucheng

I think the RTL support is good to go now.
For any other tweaks I might be doing in my fork, will wait few weeks before opening a new PR so you can review them all at once.

Although I have one question: Can we have the footer content localized? (the one which includes the hugo-eureka link)

That's a good idea and I think it is possible. I will look into that later ;-)

Just one quick remainder for your further development, you need to set hugo to production in order to purge the css if you want to update the cached resources. I found that the cached assets were like 4.4mb, but after purging, it would be around 20-25kb. I have fixed this issue so don't worry about it.
