Re^2: Lose first element of hash in hash ..

jethro, thanks for suggesting that .. It produced some interesting output!

'THINGS' => {
                          'pillow' => 'Nice soft pillow ..',
                          'sheets' => 'Long white sheets .. You slept 
+in them last night.
',
                          '
 bed' => 'There is some sheets and a pillow here'
[download]

The one that is missing, kind of falls out of the print instead of being listed nicely togetehr with the other ones. That datadumper is a pretty useful tool! (I learn so much new here everyday :)

Setting `$Data::Dumper::Useqq = 1;` would make it clearer, but the issue is that the key is `"\nbed"` (newline-b-e-d)	[reply] [d/l] [select]

It seems that the key you are looking for is not stored as 'bed' but as '\nbed'.	[reply]

ikegami, jethro, thanks for your kind help. Ok, that is pretty crazy but it makes sense, and I suspected something along those lines (that it is stored as \nbed instead of bed. But how can it? It is read from a text file composed in vi that reads: `bed-There is some sheets and a pillow here-pillow-Nice soft pillow ..- +sheets-Long white sheets .. You slept in them last night.` [download] I dont know where the \n comes from. I would suspect that the \n would terminate the line (from a CR) not initiate it. ta	[reply] [d/l]

Well, if you do `cat rooms.txt` what do you see? `> cat rooms.txt bed-There is ...` [download] or `> cat rooms.txt bed-There is ...` [download] If you see the second variant, then you have a \n at the start of your file. Maybe you should read the file line by line, or sanitize your input.	[reply] [d/l] [select]

jethro, when I cat the text I get no \n except at the end of lines. I just did `$_ =~ s/\n//g;` and that got rid of the problem, I guess that is a way of sanitizing input? Thanks, ta	[reply] [d/l]
