Please update the API with new languages and data.

[LucasMW]

While this data appears to exist in the repository, it still not available in the API.
Can you please update it?

I am also willing to contribute with new language and calendar data.

I would run in my servers if I could, but wasn't able to install the required gems both in mac and in linux. So, I rely on calling the api.

Thanks in advance.

While this data appears to exist in the repository, it still not available in the API.

Correct.

Can you please update it?

No, sorry. My resources are limited and my priorities are elsewhere.

I would run in my servers if I could, but wasn't able to install the required gems both in mac and in linux.

I may help overcome the issues if you elaborate.

[LucasMW]

I run with issues just by trying to run bundle install.
It refuses to install the gems.
Did not manage to make it work both on Mac OS or Linux.
Back in that day, I did try it for a long and on a linux machine too, so it is not just the mac os permissions.

I am not familiar with the ruby ecosystem, so I may be missing something obvious.

Here is what happens if I try it just now:
bundle install

An error occurred while installing ffi (1.9.18), and Bundler cannot
continue.
Make sure that gem install ffi -v '1.9.18' --source 'https://rubygems.org/'
succeeds before bundling.

In Gemfile:
guard-rack was resolved to 2.2.0, which depends on
guard was resolved to 2.14.1, which depends on
listen was resolved to 3.1.5, which depends on
rb-inotify was resolved to 0.9.10, which depends on
ffi

I don't expect you to do it for free, though.
I will happily make a donation for the fix.

I did not try to make it run on docker, because I would have to install docker (both on my machine and the server) I would like to make it into a binary.
If you tell me docker is the only thing that works, I guess I would try it.

(Thanks, I don't accept donations.)

It seems you're running Ruby 2.6.0. C header files for Ruby are available. Compilation of native extensions for ffi v1.9.18 fails, the critical bit is

compiling Call.c
Call.c:355:5: error: call to undeclared function 'rb_thread_call_without_gvl';
ISO C99 and later do not support implicit function declarations
[-Wimplicit-function-declaration]
rbffi_thread_blocking_region(call_blocking_function, data, (void *) -1,
NULL);

See this report of the same issue for possible solutions.

Preferable is running $ bundle update ffi and then $ bundle install. It should work fine, as even the latest release of ffi supports rubies down to 2.5.0 and our Gemfile.lock has very vague version constraints for this gem.

Second option is tweaking options passed to the C compiler $ bundle config build.ffi -- --with-cflags=-Wno-implicit-function-declaration
