JRuby Support

[jeremyhaile]

twitter-text 2.x depends on the idn-ruby gem which doesn't currently support JRuby. This means that twitter-text also doesn't work on JRuby.

Was this intentional? Is there any workaround? Can the dependency on idn-ruby be made optional?

[iantheparker]

I second making idn-ruby optional. I'd happily take an error message saying that a domain name in kanji can't be supported over having to deal with idn-ruby ( which looks like a dead gem dependent on some ugly hackery to install libidn )

[bartkamphorst]

This dependency on idn-ruby also breaks JRuby support for gollum. We too would appreciate it if idn-ruby were made optional.

Also, having trouble installing idn-ruby even in a standard Rails-MRI setup. @kaushlakers Any thoughts on what and when solution are you folks considering for this?

[zegomesjf]

brew install libidn

[octopusinvitro]

@zegomesjf is there anything like that for Ubuntu users? I tried sudo apt-get install idn, and the library is installed, but the gem can't find it.

I also tried installing as indicated here: http://www.gnu.org/software/libidn/ but the gem still can't find it

Finally I followed the instructions here: http://www.linuxfromscratch.org/blfs/view/cvs/general/libidn.html the gem still can't find it.

This is the error message I get:

[dfutrille]

Try with this: sudo apt-get install libghc-gnuidn-dev This fix it for me!

[tsutsui]

FYI, @shibafu528 has patches for twitter-text to use simpleidn https://github.com/mmriis/simpleidn instead of idn-ruby https://github.com/shibafu528/twitter-text/commit/80cdb0c76e64a71401c1bd4cb2f58327c82d99ff with some modification https://github.com/shibafu528/simpleidn/commit/69420ce9777a4b2a338dd981b31a3d4fc39dd72b

[rburton]

For mac, do brew install libidn and then you can install gem install idn-ruby -v '0.1.0' --source 'https://rubygems.org/'

[xijo]

I'd like to bump this issue. On apple m1 arm64 architecture libidn does no longer compile, so brew install libidn is no longer valid.

Is there any reason why switching to simpleidn is not a good idea?

[teomores]

For those using the apple m1, you can install it by passing the path to the lib as it does not seem to be able to find it otherwise. Something like:

bew install libidn
gem install idn-ruby -v '0.1.0' -- --with-idn-dir=/opt/homebrew/Cellar/libidn/1.36/

This solution worked for me except libidn is now 1.41. Thank you so much!
