File irb_debug_level.patch added

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
=> 1
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:indebug_level=’
…(省略)…

conf.debug_level
MATCH: start : #<RubyLex:0x00000000f613a0 …(省略)…
=> 1

RubyLex.debug_level
MATCH: start : #<RubyLex:0x00000001a85470 …(省略)…
=> 1

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

I think the patch
https://bugs.ruby-lang.org/attachments/2611/irb_debug_level.patch should
be applied for init.rb.

Bug #6301: irb 起動後に conf.debug_level を変更するとエラーになる
https://bugs.ruby-lang.org/issues/6301#change-35082

Author: sho-h (Sho H.)
Status: Closed
Priority: Normal
Assignee: keiju (Keiju Ishitsuka)
Category: lib
Target version:
ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux]

$ 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:indebug_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。
