Bug #6301: irb 起動後に conf.debug_level を変更するとエラーになる

$ irb --irb_debug <数字> などでは問題ありませんが、irb の起動後に conf.debug_level を設定するとエラーになるようです。(1.9.3-p125 で確認しましたが、trunk でも同様のようです)

conf.debug_level = "1"
NoMethodError: undefined method debug_level=' for IRB::SLex:Class from /home/sho-h/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1/irb/context.rb:245:in debug_level='

IRB::SLex.debug_level を代入するのを止めるか、debug_level を追加するのがよいのではないかと思いました。

すみません。昨日は気づきませんでしたが、conf.debug_level は irb の起動後に再度代入するまでは効いていないようでした。

$ irb

RubyLex.debug_level
=> 0
conf.debug_level

conf.debug_level = 1
NoMethodError: undefined method debug_level=' for IRB::SLex:Class from /home/sho-h/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1/irb/context.rb:245:in debug_level='

RubyLex.debug_level

昨日の提案の修正に加えて以下が必要なのではないかと思いました。

• IRB.conf[:DEBUG_LEVEL] のデフォルト値を 0 に揃える(現状の実際の動作を維持)
• lib/irb/init.rb で conf.debug_level の値を反映させる

Sho, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

• lib/irb/init.rb, lib/irb/context.rb: fix conf.debug_level=

After the changeset r38611, the output of irb is too verbose by default.
