这是我当前用于 ircd 配置文件生成器的代码,我试图能够使用answer_or_default
它,并弄清楚使用HighLine::Question#gather
这是answer_or_default
a = HighLine.new($stdin, $stderr)
connect_pingfreq = a.ask("? ", Integer) do |q|
q.default = 240
q.in = 0..300
# q.answer_or_default
# gives
# /var/lib/gems/2.0.0/gems/highline
# -1.7.8/lib/highline/question.rb:217:in
# `answer_or_default': wrong number of arguments (0 for 1) (ArgumentError)
end
# I've used it here as
# connect_pingfreq.answer_or_default
# But then gives the error shown
# ?
# /home/ken/git/shell-scripts/inspigen/generator.rb:48:in `conf':
# undefined method `answer_or_default' for 240:Fixnum (NoMethodError)
在内部使用 answer_or_default 时,我不太确定如何为其提供文档所说的“answer_string”。
然后 240 是给出的答案,但我无能为力。
我还想学习HighLine::Question#gather
使用这段代码的用法。考虑到我不太了解它的文档
a = HighLine.new($stdin, $stderr)
a.say "Your <admin> lines.."
admin_name = a.ask "Admin Real Name? "
admin_nick = a.ask "Admin Nick? "
admin_email = a.ask("Admin Email? ") do |q|
q.validate = /\A([\w+\-].?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/
end
#gather 应该向我询问 3 行、姓名、昵称和电子邮件
无论是散列还是数组,但我相信散列会更容易阅读。
