History

kouji 7eb66d1c7b * ext/readline/extconf.rb: checked to have clear_history in readline library. * ext/readline/readline.c (hist_get, hist_each, Init_readline): The offset specified for the argument of history_get() might be different in GNU Readline and libedit. If use libedit, it was corrected that the computational method of the offset specified for the argument of history_get() when the Readline module was initialized was decided. (hist_get, hist_set): If use libedit, accesses first an input content in history when specifies the negative offset for the argument of history_get() or replace_history_entry(). Then checks the offset is negative in ruby. (rb_remove_history): When compiling, it corrects it to warning when libedit is used. (hist_clear, Init_readline): added Readline::HISTORY.clear method. [ruby-dev:35551] * test/readline/test_readline_history.rb: added unit test for Readline::HISTORY. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@18313 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2008-08-01 15:04:37 +00:00

Extension for GNU Readline Library

Example:

  require "readline"
  include Readline

  line = readline("Prompt> ", true)

  should take input-string, and return an array of completion
  candidates.

completion_proc

  Returns the completion Proc object.

completion_case_fold = bool

  Sets whether or not to ignore case on completion.

completion_case_fold

  Returns true if completion ignores case.

completion_append_character = char

  Specifies a character to be appended on completion.
  Nothing will be appended if an empty string ("") or nil is
  specified.

completion_append_character

  Returns a string containing a character to be appended on
