It seems that rdoc of lang/ruby26 is broken.

Have you installed it rubygem-rdoc for Ruby 2.6? See how /usr/local/bin/rdoc be. It is just a wrapper script since Ruby 2.6. Not an rdoc itself. rubygem-rdoc port needs to be installed. Same with irb. Ruby < 2.6, /usr/local/bin/irb is a irb itself. However Ruby >= 2.6 , it is no longer irb itself. It is a wrapper script to call irb gem. irb gem port doesn't exist right now. It should be created.
I've created bug 237830 for irb.
(In reply to Koichiro Iwao from comment #2) Yes, I confirmed that installing rubygem-rdoc makes rdoc work. However, I cannot think that it is intentional to installbroken rdoc without rubygem-rdoc installed.
(In reply to Hajimu UMEMOTO from comment #4) It is not intentional. What about adding these gems runtime dependency of lang/ruby26?
Created attachment 204366 [details] patch
(In reply to Koichiro Iwao from comment #5) Adding run_depend to gems is still workaround. Installing broken rdoc by lang/ruby26 seems bad idea.
(In reply to Hajimu UMEMOTO from comment #7) However, it is a gem. What is your plan?
(In reply to Koichiro Iwao from comment #8) I'm not sure how the default gem should be handled, but, the default gem seems different from the regular gem. Perhaps, it should be: 1. Stop installing the broken bin scripts and useless related libs if any, by lang/ruby26. 2. Providing the separated default gem port like ruby26-rdoc which built and installed from the Ruby 2.6.X source. 3. The separated default gem port installs the bin script as well. 4. Optionally, the separate ports are RUN_DEPENDS from lang/ruby26. 5. The rubygem-rdoc can be installed to use latest version of the rdoc.
I will learn about default gem and consider what should be done.
As I already mentioned, irb, rdoc, ri and perhaps other components are installed as default gems since Ruby 2.6. However, files/patch-tool_rbinstall.rb prevents installing default gems. This is the cause why rdoc etc is not installed. https://svnweb.freebsd.org/ports/head/lang/ruby26/files/patch-tool_rbinstall.rb?revision=501068&view=markup#l27 There should be a certain reason why this patch is added. Just removing the patch might break something so the patch needs to be removed carefully.
Ruby 2.6 is now default r511605. Let's make irb, rdoc, ri as part of lang/ruby26.
After upgrading to Ruby 2.6 I can no longer start irb: $ irb Traceback (most recent call last): 2: from /usr/local/bin/irb:23:in `<main>' 1: from /usr/local/lib/ruby/site_ruby/2.6/rubygems.rb:303:in `activate_bin_path' /usr/local/lib/ruby/site_ruby/2.6/rubygems.rb:284:in `find_spec_for_exe': can't find gem irb (>= 0.a) with executable irb (Gem::GemNotFoundException) This is with ruby-2.6.4,1 compiled with Poudriere using default make options on FreeBSD 12.0-REL amd64. Thanks.
(In reply to mail from comment #13) Have you tried to install what the error message tells you? pkg install rubygem-irb
(In reply to Matthias Fechner from comment #14) OK, irb works after installing devel/rubygem-irb. I'm not a Ruby user so that step was non-obvious, nor was it automatic after upgrading from Ruby 2.5. Obviously rubygem-irb should be required as a dependency for a functioning Ruby installation.
