■ [Ruby] irbで履歴を保存する方法

2,3日前にtwitterであーありがちな人が困っていたので一応書いておこう。
~/.irbrcに

require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 1000

と書けばok。1000は残したい履歴の最大数。

■ [Ruby] irbrcの罠

~/.irbrcで間違ったrequireを書いてもそれ以降は無視される。
昨日実は

require 'irb/ext/save-hisotry'

と最初は書いていたんだけど、エラーにならず単に無視されるので、
なかなか気づかなかった。irb/init.rbを見ると

def IRB.run_config
  if @CONF[:RC]
    begin
      load rc_file
    rescue LoadError, Errno::ENOENT
    rescue
      print "load error: #{rc_file}\n"
      print $!.class, ": ", $!, "\n"
      for err in $@[0, $@.size - 2]
        print "\t", err, "\n"
      end
    end
  end
end

のようになぜかわざと無視してんだけど、これは一体何の罠？

■ [Life] 花粉症？

家に帰ったら急にくしゃみ連発で鼻水が止まらない。
秋も花粉症ってのはさすがに避けたいんだが。
