Hi I have a string passed back from rspec.
It should show
"alias/public_html/ab1/ab2/"
but I am getting "\"alias/public_html/ab1/ab2/\""
I am getting the rspec error below:
WebServer::HttpdConf#alias_path returns the aliased path
Failure/Error: expect(httpd_file.alias_path('/ab/')).to eq 'alias/public_html/ab1/ab2/'
expected: "alias/public_html/ab1/ab2/"
got: "\"alias/public_html/ab1/ab2/\""
(compared using ==)
# ./spec/lib/config/httpd_conf_spec.rb:90:in `(root)'
And here is my actual program file
def alias_path(path)
#hash_httpd['Alias'][path]
end
Please help
EDIT
Sorry, I am new to RUby, here is the httpd_file
def initialize(httpd_file_content)
#hash_httpd = Hash.new
httpd_file_content.each_line do | line |
#commands = line.split
if #commands.length == 2
#hash_httpd[#commands[0]] = #commands[1]
else
if !#hash_httpd.has_key?(#commands[0])
al = Hash.new
#hash_httpd[#commands[0]] = al
else
al = #hash_httpd[#commands[0]]
end
al[#commands[1]] = #commands[2]
end
end
end
If you are sure that your alias_path output will be "alias/public_html/ab1/ab2/", then you can just modify your alias_path method definition by removing the quotes (if any) from the returned path:
def alias_path(path)
#hash_httpd['Alias'][path].gsub('"', '')
end

What is the best way to write a function (or something DSLish) that will allow me to write this code in Ruby. How would I construct the function write_pair?
username = "tyndall"
write_pair username
# where write_pair username outputs
username: tyndall
Is it possible to do? Looking for the most simple way to do this.
Sure it is possible!
My solution tests the var by Object#object_id identity: http://codepad.org/V7TXRxmL
It's crippled in the binding passing style ...
Although it works just for local vars yet, it can be easily be made "universal" adding use of the other scope-variable-listing methods like instance_variables etc.
# the function must be defined in such a place
# ... so as to "catch" the binding of the vars ... cheesy
# otherwise we're kinda stuck with the extra param on the caller
#_binding = binding
def write_pair(p, b = #_binding)
eval("
local_variables.each do |v|
if eval(v.to_s + \".object_id\") == " + p.object_id.to_s + "
puts v.to_s + ': ' + \"" + p.to_s + "\"
end
end
" , b)
end
# if the binding is an issue just do here:
# write_pair = lambda { |p| write_pair(p, binding) }
# just some test vars to make sure it works
username1 = "tyndall"
username = "tyndall"
username3 = "tyndall"
# the result:
write_pair(username)
# username: tyndall
If it's possible for you to use a symbol instead of the variable name, you could do something like this:
def wp (s, &b)
puts "#{s} = #{eval(s.to_s, b.binding)}"
end
In use:
irb(main):001:0> def wp (s, &b)
irb(main):002:1> puts "#{s} = #{eval(s.to_s, b.binding)}"
irb(main):003:1> end
=> nil
irb(main):004:0> var = 3
=> 3
irb(main):005:0> wp(:var) {}
var = 3
Note that you must pass the empty block {} to the method or it cannot get the binding to evaluate the symbol.
You can't actually get a variable's name in Ruby. But you could do something like this:
data = {"username" => "tyndall"}
Or even,
username = "tyndall"
data = {"username", "password", "favorite_color"}
data.each { |param|
value = eval(param)
puts "#{param}: #{value}"
}
I made a vim macro for this:
" Inspect the variable on the current line (in Ruby)
autocmd FileType ruby nmap ,i ^"oy$Iputs "<esc>A: #{(<esc>"opA).inspect}"<esc>
Put the variable you'd like to inspect on a line by itself, then type ,i (comma then i) in normal mode. It turns this:
foo
into this:
puts "foo: #{(foo).inspect}"
This is nice because it doesn't have any external dependencies (e.g. you don't have to have a library loaded up to use it).
Building on previous answers relating to symbols & bindings ... if passing in the variable name as a symbol works for you (who doesn't love cutting out extra keystrokes?!), try this:
def wp(var_name_as_sym)
# gets caller binding, which contains caller's execution environment
parent_binding = RubyVM::DebugInspector.open{|i| i.frame_binding(2) }
# now puts the symbol as string + the symbol executed as a variable in the caller's binding
puts %Q~#{var_name_as_sym.to_s} = #{eval("#{var_name_as_sym.to_s}.inspect", parent_binding)}~
end
aa=1
bb='some bb string'
os = OpenStruct.new(z:26, y:25)
Console output:
> wp :aa
aa = 1
=> nil
> wp :bb
bb = "some bb string"
=> nil
> wp :os
os = #<OpenStruct z=26, y=25>
=> nil
Using ruby 2.2.2p95
(Credit to banister for getting binding of calling context)
This is a simple solution:
def write_pair(variable)
puts variable + eval(variable)
end
This is more readable:
def write_pair(variable)
puts 'A' * 100
puts variable + ': ' + eval(variable).inspect
puts 'Z' * 100
end
Invocation:
write_pair "variable"
def write_pair var, binding
puts "#{ var } = #{ eval(var, binding)}"
end
username = "tyndall"
write_pair "username", binding
This seems weird because binding is never defined, but it works. From Ruby: getting variable name:
The binding() method gives a Binding object which remembers the
context at the point the method was called. You then pass a binding
into eval(), and it evaluates the variable in that context.
Be sure to pass a string, not the variable.
# make use of dynamic scoping via methods and instance vars
#_binding = binding
def eval_debug(expr, binding = #_binding)
"#{expr} => #{eval(expr, binding)}"
end
# sample invocation:
x = 10
puts eval_debug "x"
puts eval_debug "x**x"
I am getting an error when executing my test.
Failure/Error: expect(industry_sic_code).to include page.sic_code
TypeError:

I have tried to implicitly change each variable to a string but it still complain about the array issue.
When I include some puts statments, I get some really wonky responses. The method itself returns the expected result.
When I used the method in the test I end up with the code gibberish below.

Your sic_code method returns subtables array, that's why you have this error. It doesn't matter that the method puts something, every method in ruby implicitly returns result of its last line, in your case it is subtables.each do ... end, so you have an array.
You need to explicitly return needed value. Not sure if I correctly understood what are you doing in your code, but try something like this:
def sic_code
subtables = #b.table(:class => 'industry-codes').tables(:class => 'industry-code-table')
result = [] # you need to collect result somewhere to return it later
subtables.each do |subtable|
if subtable.tbody.h4.text == "US SIC 1987:"
subtable.tr.next_siblings.each do |tr|
codes = tr.cell
result << codes.text.to_s
end
end
end
result.join(', ')
end
I want to execute Ruby code if command line argument is present:
ruby sanity_checks.rb --trx-request -e staging_psp -g all
Ruby code:
def execute
command_options = CommandOptionsProcessor.parse_command_options
request_type = command_options[:env]
tested_env = command_options[:trx-request] // check here if flag is present
tested_gateways = gateway_names(env: tested_env, gateway_list: command_options[:gateways])
error_logs = []
if(request_type.nil?)
tested_gateways.each do |gateway|
........
end
end
raise error_logs.join("\n") if error_logs.any?
end
How I can get the argument --trx-request and check is it present?
EDIT:
Command parser:
class CommandOptionsProcessor
def self.parse_command_options
command_options = {}
opt_parser = OptionParser.new do |opt|
opt.banner = 'Usage: ruby sanity_checks.rb [OPTIONS]'
opt.separator "Options:"
opt.on('-e TEST_ENV', '--env TEST_ENV','Set tested environment (underscored).') do |setting|
command_options[:env] = setting
end
opt.on('-g X,Y,Z', '--gateways X,Y,Z', Array, 'Set tested gateways (comma separated, no spaces).') do |setting|
command_options[:gateways] = setting
end
end
opt_parser.parse!(ARGV)
command_options
end
end
Can you advice?
You will need to add a boolean switch option to your OptionParser like so
opt.on('-t','--[no-]trx-request','Signifies a TRX Request') do |v|
# note we used an underscore rather than a hyphen to make this symbol
# easier to access
command_options[:trx_request] = v
end
Then in your execute method you can access this as
command_options[:trx_request]
If you need to have a default value you can add one in the parse_command_options method by setting it outside the OptionParser as command_options[:trx_request] = false
I am working on a CLI Project and trying to open up a web page by using url variable declared in another method.
def self.open_deal_page(input)
index = input.to_i - 1
#deals = PopularDeals::NewDeals.new_deals
#deals.each do |info|
d = info[index]
#product_url = "#{d.url}"
end
#product_url.to_s
puts "They got me!"
end
def self.deal_page(product_url)
#self.open_deal_page(input)
deal = {}
html = Nokogiri::HTML(open(#product_url))
doc = Nokogiri::HTML(html)
deal[:name] = doc.css(".dealTitle h1").text.strip
deal[:discription] = doc.css(".textDescription").text.strip
deal[:purchase] = doc.css("div a.button").attribute("href")
deal
#binding.pry
end
but I am receiving this error.
`open': no implicit conversion of nil into String (TypeError)
any possible solution? Thank you so much in advance.
Try returning your #product_url within your open_deal_page method, because now you're returning puts "They got me!", and also note that your product_url is being created inside your each block, so, it won't be accessible then, try creating it before as an empty string and then you can return it.
def open_deal_page(input)
...
# Create the variable
product_url = ''
# Assign it the value
deals.each do |info|
product_url = "#{info[index].url}"
end
# And return it
product_url
end
In your deal_page method tell to Nokogiri to open the product_url that you're passing as argument.
def deal_page(product_url)
...
html = Nokogiri::HTML(open(product_url))
...
end
my environment: ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]
The thing is, I can make ruby return the parameters sent over GET. but when i'm trying to use them as arguements to my methods in if/else, ruby wont return anything and I end up with a blank page.
ph and pm return correctly:
http://127.0.0.1/cgi-bin/test.rb?hostname=node00.abit.dk&macadd=23:14:41:51:63
returns:
node00.abit.dk 23:14:41:51:63
Connection to the database (MySQL) works fine
When I test the method newHostName it outputs correctly:
puts newHostName
returns (which is correct)
node25.abit.dk
the code:
#!/usr/bin/ruby
require 'cgi'
require 'sequel'
require 'socket'
require 'timeout'
DB = Sequel.connect(:adapter=>'mysql', :host=>'localhost', :database=>'nodes', :user=>'nodeuser', :password=>'...')
#cgi-part to work
#takes 2 parameters:
#hostname & macadd
cgi = CGI.new
puts cgi.header
p = cgi.params
ph = p['hostname']
pm = p['macadd']
def nodeLookup(hostnameargv)
hostname = DB[:basenode]
h = hostname[:hostname => hostnameargv]
h1 = h[:hostname]
h2 = h[:macadd]
ary = [h1, h2]
return ary
end
def lastHostName()
#TODO: replace with correct sequel-code and NOT raw SQL
DB.fetch("SELECT hostname FROM basenode ORDER BY id DESC LIMIT 1") do |row|
return row[:hostname]
end
end
def newHostName()
org = lastHostName
#Need this 'hack' to make ruby grep for the number
#nodename e.g 'node01.abit.dk'
var1 = org[4]
var2 = org[5]
var3 = var1 + var2
sum = var3.to_i + 1
#puts sum
sum = "node" + sum.to_s + ".abit.dk"
return sum
end
def insertNewNode(newhost, newmac)
newnode = DB[:basenode]
newnode.insert(:hostname => newhost, :macadd => newmac)
return "#{newnode.count}"
end
#puts ph
#puts pm
#puts newHostName
cgi.out() do
cgi.html do
begin
if ph == "node00.abit.dk"
puts newHostName
else
puts nodeLookup(ph)
end
end
end
end
I feel like im missing something here. Any help is very much appreciated!

What about modify last lines of your code as followed? CGI HTML generation methods take a block and yield the return value of the block as their content. So you should make newHostName or nodeLookup(ph) as the return value of the block passed to cgi.html(), rather than puts sth, which prints the content to your terminal and return nil. That's why cgi.html() got an empty string (nil.to_s).
#puts newHostName
cgi.out() do
cgi.html do
if ph == "node00.abit.dk"
newHostName
else
nodeLookup(ph)
end
end
end
p.s. It's conventional to indent your ruby code with 2 spaces :-)
