Hey, just trying to kick the tires on jard and I got the error mentioned above. Using Ruby 2.6.3 and RVM. Here's the script:
#!/usr/bin/env ruby
require 'ruby_jard'
def sieve(n)
primes = (0..n).to_a
limit = Math.sqrt(n)
jard
(2..limit).each do |i|
(( i + i )..n).step(i) do |x|
primes[x] = nil
end
end
primes.compact
end
puts sieve(100).inspect
and the traceback:
Internal error from Jard. I'm sorry to mess up your debugging experience.
It would be great if you can submit an issue in https://github.com/nguyenquangminh0711/ruby_jard/issues

Thanks.

Hi @ruprict, thank you for your bug report. I already pushed a patch as an attempt to fix your error. Could you try again with the source code on master branch, by putting this in your gem file, and run bundle update ruby_jard?
gem 'ruby_jard', git: 'https://github.com/nguyenquangminh0711/ruby_jard'I tested the patch with Ruby 2.6.3 installed by RVM in my local machine, and it works quite well.
The root cause of the bug is still unknown. Internally, Ruby Jard uses Ruby's IO Console (https://ruby-doc.org/stdlib-2.6.3/libdoc/io/console/rdoc/IO.html) to achieve cursor movement, screen cleaning, etc. It is a C extension belong to Ruby's stdlib. So, maybe, your ruby installation in your machine skips this extension. I removed the dependency, and use ANSI escape sequence instead.
I'm not sure whether the patch could fix your issue or not, so I will publish a release after the fix is confirmed. If it doesn't work or gets weird behaviors again, please let me know some more information, including: your operating system, your terminal emulator, the output if you run tput colors?

It is so weird. Could you provide some more information about your environment, like your operating system, or your terminal emulator? And if it is possile, could you provide the output from tput colors?

Mac OS Catalina (10.15.4)
I do use tmux, but I am not using it for this.

Hi @ruprict, I pushed another patch into master of the Gem. Could you try again? In this patch, I added multiple fallback mechanism to serve the case that io/console is not available, or even tput is not available. I tested the patch with a custom Ruby build without io/console, and borrow a Mac OS catalina machine to test, and it works now. Sorry for wasting for time on this back, and forth debugging.
ruprict commented
That did it! And this is not wasting time, this is open source. Glad to help.
