Help with array

Ruby

Hello team,

I am having an issue with the code below.
Could you please take a quick look at the highlighted and commented code
below and let me know what’s wrong?

Thank you

Victor

input.file
group.was=hostname1 hostname.2 hostname.r3
group.web=webserver1 webserver2 webserver3 hostname1
/usr/local/bin/test.sh
web /usr/local/bin/testcmd.sh
#end of input.file

Program

@myhostname = hostname # webserver3
#comment# The intent is to create a arrays “was” and “web” and to assign
the
values in the group statement
IO.foreach(“inpit.file”) do |line|
if line =~ /^#/ || line.chomp.length == 0
next
end # if line
if line.upcase =~ /^GROUP/
grouplit, groupinfo = line.split(".")
groupname, groupentries = groupinfo.split("=")
#{groupname} = groupname.to_a
groupname = groupentries.split
next
end # if GROUP
targetserver, command = line.split(" ")
if targetserver == @myhostname
@runcommand = true
end # if targetserver
#comment# In this case I’m trying to determine if “myhostname” is in the
array “web”
#comment# I’ve tried a number of ways to get the following to work
without
success
if #{targetserver}.include? “#{@myhostname %23{@myhostname}”
####### THIS IS WHERE THE FAILURE IS
@runcommand = true
end # if
end
exit

Try to parse this code

if
@runcommand = true
end

Do you see what is wrong?
If not scroll down :wink:

The escape #{ works in string literals only, so you probably just
wanted to write

if targetserver.include? “#{@myhostname %23{@myhostname}”

I have no idea however what you meant with .include? (just high
lightening, I guess).

Victor,

In ruby, a statement like

#{foo} = ‘bar’

just won’t work. You are trying to use “dynamic variables” (ala PHP I
guess) and that simply does not work in ruby. Here is a version of your
code that I think does what you are trying to do. I removed the @
sigils on the variable names … you might need to add them back if you
took this code out of a class you are working on. I also stored the
group arrays in a ruby Hash object keyed by the group name. There are
other ways to do this, the best one depends on your specific needs. You
also had what looked to be a misspelling in the IO.foreach statement:
your version was opening ‘inpit.file’ not ‘input.file’.

Program

#@myhostname = hostname # webserver3
myhostname = ‘webserver3’
runcommand = false
command_to_run = nil
#comment# The intent is to create a arrays “was” and “web” and to assign
the values in the group statement
groups = {}
IO.foreach(“input.file”) do |line|
if line =~ /^#/ || line.chomp.length == 0
next
end # if line
if line.upcase =~ /^GROUP/
grouplit, groupinfo = line.split(".")
groupname, groupentries = groupinfo.split("=")
groups[groupname] = groupentries.split
next
end # if GROUP
targetserver, command_to_run = line.split(" ")
if targetserver == myhostname
runcommand = true
end # if targetserver
#comment# In this case I’m trying to determine if “myhostname” is in the
array “web”
#comment# I’ve tried a number of ways to get the following to work
without success
end

if groups[‘web’].include?(myhostname)
####### THIS IS WHERE THE FAILURE IS
runcommand = true
end
puts “groups: #{groups.inspect}”
puts “run command: #{runcommand}, command: #{command_to_run}”
exit
