这是我目前的ircd配置文件生成器代码,
我尝试使用answer_or_default
进行此操作,并弄清楚HighLine::Question#gather
的使用
这里是answer_or_default
a = HighLine.new($stdin, $stderr)
connect_pingfreq = a.ask("? ", Integer) do |q|
q.default = 240
q.in = 0..300
# q.answer_or_default
# gives
# /var/lib/gems/2.0.0/gems/highline
# -1.7.8/lib/highline/question.rb:217:in
# `answer_or_default': wrong number of arguments (0 for 1) (ArgumentError)
end
# I've used it here as
# connect_pingfreq.answer_or_default
# But then gives the error shown
# ?
# /home/ken/git/shell-scripts/inspigen/generator.rb:48:in `conf':
# undefined method `answer_or_default' for 240:Fixnum (NoMethodError)
当在里面使用answer_or_default时,我不太确定如何给它“answer_string”'文档说它想要。
然后240是给出的答案,但我无法完全做任何事情。
我也想学习HighLine::Question#gather
使用这段代码。考虑到我不太了解它的文档
a = HighLine.new($stdin, $stderr)
a.say "Your <admin> lines.."
admin_name = a.ask "Admin Real Name? "
admin_nick = a.ask "Admin Nick? "
admin_email = a.ask("Admin Email? ") do |q|
q.validate = /\A([\w+\-].?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/
end
#gather应该问我3行,姓名,昵称和电子邮件
在散列或数组中,但我相信散列会更容易阅读。
答案 0 :(得分:0)
对于您的第一个问题,您可以从connect_pingfreq
变量中获得答案(或默认值)。无需致电answer_or_default
。像这样:
a = HighLine.new($stdin, $stderr)
connect_pingfreq = a.ask("? ", Integer) do |q|
q.default = 240
q.in = 0..300
end
puts connect_pingfreq
这将输出用户输入的答案或默认值240。
