Hi all, i require some assistance writing a "sleep timer" for my HTPC, that i can increment with a remote keypress, and it will execute a script when the timer reaches 0. Can anyone help?
<rue>
What've you got so far?
<Nasha>
An idea :) I've merely played around with ruby, and gained an interest, so i thought i would come here and see if someone could help me with my problem, and at the same time further my knowledge of the langugae

Hey guys, why does output.txt not contain any data once the script is finished? http://pastie.org/3750114
kvirani has joined #ruby-lang
<shevy>
perhaps because output is an array
<shevy>
tried output.join("\n") yet?
<shevy>
hmmm also
<shevy>
are you sure that output is not nil?
<robgleeson|mba>
puts also returns nil :p
<shevy>
ridders24, do a puts output or puts output.class, or even better ... require 'pp' then pp output, before you call to File.open
<shevy>
I suppose output is nil
<ridders24>
why would output be nil?
<robgleeson|mba>
you can return nil from find.
<shevy>
who knows, it is your code man
<shevy>
I am just trying to help find errors
<robgleeson|mba>
-can
<bnagy>
ridders24: what are you trying to do? Find .txt files? That's a hideous way of doing it
<ridders24>
the script gives me the data i want in console but doesnt output that data into the txt file
<shevy>
the code you used to write into a file would work correctly. so something is wrong with the variable output. it is logical.
<bnagy>
just use globbing
<ridders24>
bnagy: i was using glob but mistym suggested to use find.find as i have more to add to the script regarding an expression I will be looking for
hexo has joined #ruby-lang
<robgleeson|mba>
ridders24: check the documentation for Find.find(…), it doesn't return anything worthwhile.
<shevy>
fixed the script yet? ;)
<robgleeson|mba>
it always returns 'nil'.
<robgleeson|mba>
if you want to use find you might want to keep a open File object around, and insert when you find something.
<robgleeson|mba>
then close.
<bnagy>
anyway, it's broken because you aren't saving your find stuff, you're just doing pts in the block
<bnagy>
open the file handle, then do f.puts path ... inside your Find block
<robgleeson|mba>
bnagy: did you see what I wrote? lol
<bnagy>
no, I can't read or write
<robgleeson|mba>
you repeated everything I said before you, seems kinda redundant but ok :p
<bnagy>
yeah but more clearly :)
<ridders24>
could you give an example so i know what you mean, sorry really struggling with that...
<robgleeson|mba>
you forgot to tell him to close bnagy, tut tut!
<robgleeson|mba>
j/k
<bnagy>
yeah in a 4 line script I think we can skip close :>
<bnagy>
ok, not clearly enough, it seems
<bnagy>
f=File.open('output.txt','w');Find.find("C:/") {||p| f.puts p if File.extname( p )=='.txt'}
* shevy
rolls robgleeson|mba onto bnagy and watches what happens next
<shevy>
ridders24 does it work finally? :P
<robgleeson|mba>
it doesn't matter if a finalizer does it for you or not, good practice is to close when you don't need it no more, and who knows the larger context he is writing this in.
<bnagy>
2 line scripts aren't programming.. wait 3 lines because of the random use of Find
<ridders24>
shevy: does testing it now
<erikh>
moo
<bnagy>
anyway, the broken code already had the close, so I don't think I'm leading them astray with my evil 'files get closed on exit' ways
<ridders24>
shevy: it works :)
<ridders24>
sorry im really slow with this guys
<shevy>
finally!
<ridders24>
thanks for the help
<shevy>
one problem solved, one hundred more to go!
<erikh>
yeah but then things like File.open('foo', 'w') << text don't work
<Nasha>
Anyone want to give me 10min of their Ruby brain time, and write a script for me for $$'s?
<shevy>

In 10minutes, thats a big ask!
<bnagy>
I guess 'A' << 'A'*10000 while true simulates the performance

Ok :/ Let me describe the solution i require:
<Nasha>
Imagine your TV at home, i need to replicate it's sleep timer on my HTPC
<burgestrand>
10 minutes is half the time it takes to understand what you really want
<Nasha>
Is further understanding required as per my requirements above?
<shevy>
I dont think you need further explanation
<shevy>
in theory the requirement you explained would be one class, and threads and probably sleep. but I am sure it cant be that easy.

i havent, as I saved the spreadsheet as a txt, and the 1234 is the on the same line as the 1234-ABC-1-2. theres just divided by a space.
<ridders24>
mistym: so it probably works out better that there on the same line?
<mistym>
ridders24: OK. And I assume filenames and directories can't have spaces here ;)
<ridders24>
yh, in theory they wont have spaces, it should only be a 4 digit number if its a dir and its a file then it could be spaced with "-" so ABC-12-3

<andrewvos>
Flow control or whatever
<mistym>

<mistym>
ridders24: For example: "foo,bar".split(",") ==> ["foo","bar"]
morozovm has joined #ruby-lang

morozovm has quit [#ruby-lang]

ridders24: Well, you're going to be treating the two columns separately from each other, right? That's why you're splitting the line.
<mistym>
ridders24: Have you seen multiple assignment in Ruby yet?
<ridders24>
mistym: I havent no. and yes we treating to two columns seperatly
<mistym>
ridders24: Multiple assignment's a lovely bit of magic that lets you assign the values of multiple variables at the same time, when a method is returning multiple values
<mistym>
For example:
ridders24 has joined #ruby-lang
<ridders24>

benanne has joined #ruby-lang
<mistym>
ridders24: Well, you're going to be splitting the line so it turns into two values.
<ridders24>
mistym: ok. Lets see if I can put this to practical use. So is any of the top part of my code any good? apart from the expression
<mistym>
ridders24: A few questions from the top. Why are you using #each_with_index on your file?
<ridders24>
mistym: was just the example I had that worked
jondot has joined #ruby-lang
<ridders24>
mistym: should it be File.foreach(from_file).strip.each(' ')
fgomez has joined #ruby-lang
<mistym>
ridders24: You only have one file here. Since you're trying to read lines, you probably want to use File.readlines(from_file)!
kiddorails1 has joined #ruby-lang
<mistym>
File.readlines(from_file).each do |line|
<ridders24>
mistym: then #line.strip.each(' ') ? actually maybe i dont need the #
<mistym>
#each_with_index is a special form of each which adds a new variable to the loop, which gives you the number of the iteration. e.g. the first time the index will be 0, then 1, etc.
<mistym>
If you're not using the index, you should just use each.
<mistym>
ridders24: The hash symbol (#) just means that the method is an instance method. It's not Ruby syntax, just a convenient way to talk about method names.
<ridders24>
mistym: oops sorry
<mistym>
ridders24: Close! Rather than line.strip.each(" ") you want line.strip.split(" "). And you should make sure you assign the values of that to something.
<ridders24>
mistym: you mean like strip = line.strip.split(" ")
<ridders24>
mistym: whats the difference between (' ') and (" ")?
<mistym>
ridders24: Yes, if you want strip to equal an array. If you want separate values for the two items in it, you probably instead want something like column1, column2 = line.strip.split(" ")
elalande1 has joined #ruby-lang
<mistym>
ridders24: In this case, nothing. The difference between '' and "" has to do with the treatment of certain special characters in strings.
<ridders24>
mistym: oo i didnt know you could give more than one value to somthing
<mistym>
ridders24: An array is a set of multiple values!
<mistym>
Let's say that your line is 'foo bar'. If you do strip = 'foo bar'.strip.split(" "), then strip will equal ["foo", "bar
<mistym>
"]
<mistym>
If you do column1, column2 = 'foo bar'.strip.split(" "), then column1 will equal "foo" and column2 will equal "bar"

mistym: line should now contain the split value, so i need to add line to the expression?
<mistym>
ridders24: Mind updating the paste with what you have so far?
<mistym>
ridders24: OK! So now you want to use your columns in the Find.find block, right?
<mistym>
(ps - you might want to name the variables something that makes it clear what their purpose is. It's good habit so your code remains readable. For example, dirname and filename, or something like that.)
<ridders24>
mistym: that makes sence
<bawerd>
anyone in this channel that runs ruby on OpenSolaris/NetBSD/Illumos?
<mistym>
ridders24: You still need to check that the line matches your naming pattern, right?
<ridders24>
mistym: yh
<mistym>
Are you familiar with "next" in blocks?
<ridders24>
mistym: no is it similar to "then"
<mistym>
ridders24: Nope! next is for use in blocks that are iterating over multiple values.
<ridders24>
mistym: oh ok
<mistym>
If "next" is sent, the block will skip any of the other commands in the block and start from the next iteration.
<mistym>
For example: Find.find('/') {|file| next if file == "somefileidontwant.txt"; puts file}
<ridders24>
mistym: ahh i see, so if it finds a match it puts it, then moves on
<mistym>
ridders24: Opposite in this case! If it sees that the file matches the condition it will skip that file, then go on to the next.
<ridders24>
mistym: becuase next is before the if statement?
<mistym>
ridders24: Yeah.
<mistym>
ridders24: Thought that would be helpful here, since you said you wanted to skip some lines in your input file - right?
<ridders24>
mistym: i would like to skip any files that dont match the expression and values. so I have a list of files it locates
<mistym>
ridders24: At any rate - it looks like you're close now. You just need to check your file in the Find.find block, right?

<ridders24>
mistym: how do you mean check it? i need to add the values of dirname and filename to find.find ? to allow it to search for those right?
<mistym>
ridders24: Yes! You just need to check the file against those values.
<mistym>
ridders24: File.dirname and File.basename will probably be helpful here.

ridders24: Capital File! Those are methods in the standard Ruby library for querying the properties of files.
<mistym>
File.dirname returns the name of the directory of a file. For example, File.dirname("/Volumes/foo/bar.txt") ==> "/Volumes/foo"
<ridders24>
mistym: ok, and the other returns just the filename im guessing
<mistym>
Exactly.

ridders24: Well, think about it logically - end signals the end of a block. So, it's the end of where that iterating section of code is. Do you want to end the File.readlines(foo).each block there? Is there a reason that's not a good idea?
<ridders24>

ridders24: I probably confused things by suggesting you name a variable "dirname", since that's also a class method from File. You can rename the variable if that helps clarify things.
<ridders24>
mistym: yh i may go back to column 1 and 2
<mistym>
ridders24: Whatever's most readable. The important thing with variable names is that it should be clear what the variables hold and what they're for from how you name and use them!
<ridders24>
mistym: File.dirname(column2)
robbyoconnor has joined #ruby-lang
<mistym>
ridders24: No, column2 is already your filename, right?
<mistym>
And file 1 is the directory name the file you're looking for should be in.
<ridders24>
mistym: yh, i thought i was checking what dir it was in?
<ridders24>
mistym: or am i checking if the dir exists?
Teddy2steper has joined #ruby-lang
<mistym>
ridders24: Well, what are you doing with the columns? What are the files you're looking for and what are the conditions for when you keep them?
<ridders24>
mistym: the file name could be 1234-abc-1-2 which is fine as the filename identifies where it is. but the file could be just abc-1-2, and so the second column would confirm where it is as it would say 1234
<mistym>
ridders24: Is the first column the filename, and the second the directory?
<ridders24>
mistym: other way roud
<ridders24>
round
<mistym>
ridders24: OK.
surfprimal has joined #ruby-lang
<mistym>
So let's think of this in terms of tasks. You have the columns that give you informations on files, and in the Find.find block you have a set of arbitrary files that may or may not be how you're looking for.
<mistym>
What do you need to do to the arbitrary file (let's call it "path") to figure out if it's the one you want?
<ridders24>
mistym: ok
<ridders24>
mistym: i need path to match column1 and column2 and /\.txt$/ that in theory would be an exact match

ridders24: So this is where the File class methods come into handy. They let you look at the properties of a file.
<ridders24>
mistym: Okay
<ridders24>
mistym: do i need to do File.basename(column2) as well?
<mistym>
ridders24: column2 is already a filename, right? File.basename returns the filename of a file, given a string that could contain both the directory and filename together.
RORgasm has joined #ruby-lang
<ridders24>
mistym: not sure i need that then as if the filename contains the dir i dont need to worry about there being more that 1 file with the same name
<ridders24>
so its just the file.dirname i need to be interested in i guess
<ridders24>
mistym: do i need to give File.dirname(column1) a value, so that i can call it in find.find ?
<mistym>
ridders24: column1 is already a directory name! You don't need to use File.dirname on it, right?
<ridders24>
mistym: yh but i wasnt sure what I was ment to do with File.dirname then
<mistym>
ridders24: It's the path in Find.find whose properties you need to check.
<mistym>
Because you want to know what directory is's in, right?
<ridders24>
mistym: yh
<ridders24>
Filename.dirname(path)
<mistym>
Right. So you need to do a comparison with the result of that, right?
<ridders24>
mistym: path needs to include column1 and column2 with the .txt extenion to search for
<mistym>
ridders24: Right. So File.dirname(path) should match column1; File.basename(path) should match column2; and the path should have a .txt extension. Something like that?
voker57 has joined #ruby-lang
voker57 has joined #ruby-lang
<ridders24>
mistym: yh that sounds right
<mistym>
Little trick, by the way - if you want to get a string for a filename without its extension, do this: File.basename(path, File.extname(path))
<ridders24>
does * represent any filename? so (path, *txt(path))
<ridders24>
(path, *.txt(path))
rdeshpande has joined #ruby-lang
RomyRomy has joined #ruby-lang
<mistym>
ridders24: What do you mean? In terms of the File.basename code I was mentioning?
<ridders24>
mistym: yh
<mistym>
ridders24: Don't worry about specifying an extension. File.extname(path) returns whatever the extension is.
<mistym>
The optional second argument to File.basename just returns the filename minus that extension. So File.basename("f:\foo.txt",".txt") will return "foo".
<mistym>
File.extname("foo.txt") returns ".txt"
<ridders24>
as much as i trust the script it doesnt harm to see the extention lol
<ridders24>
for my own sake
<mistym>
ridders24: Right, but if you're comparing filenames and one has the extension and the other doesn't, then they won't be equal. You're trying to find out if they're the same!
<ridders24>
oh i see, so even though from_file contains just the filenames and no extentions, but path contains both, File.basename will ignore them as from_file doesnt contain the extention?
elalande has joined #ruby-lang
<mistym>
File.basename just returns a string. It doesn't do a comparison.
<mistym>
You can compare, e.g., str1 == str2
<mistym>
And if str1 is "foo" and str2 is "foo.txt", then it will return false for "foo" == "foo.txt"
<mistym>
That's why you want to try to chomp off the extension before comparing!
<mistym>
Yeah, you want to do those checks inside the block.
<ryanf>
in the same way that a parameter of a method is only defined inside the method
<ridders24>
grrr block!
<mistym>
Those methods are invited to the &block party.
<mistym>
You don't want them to show up at like 6am when everyone's gone home, do you?
<ridders24>
its how i feel about now though lol
<mistym>
Are you still confused? Maybe I can clarify.

mistym: i dont know how to run them inside the block
ridders24 has joined #ruby-lang

ridders24: Right now Find.find is using the single-line block syntax, whereas you're using the multiline syntax for File.open. So just switch Find.find over to the other syntax, and move those lines in!

the script didnt like f.close so i got rid of it for now and the script it running but seems to just be sitting there and not doing anything

oh hang on
<ridders24>
helps if i give it the right drive letter to look at
<ridders24>
i think the script works
<mistym>
ridders24: f.close isn't necessary since you're using the block form File.open, which autocloses the file when the block completes.
<mistym>
(Blocks, much like friendship, are magic.)
<ridders24>
mistym: the script puts in output.txt just the filenames. I need the path of where there located too

ridders24, where do you define "path"
<shevy>
I think the problem is that you are writing in a black box without feedback to you
<shevy>
you should use debug prints until the script works
<shevy>
puts f, puts path etc...
<shevy>
or as I told you even better, pp f, pp path
<shevy>
and include that output into the script you use at pastie
<mistym>
ridders24: Ah, I think I know what's going on here. I bet your files are in directories more than one level deep, right?
<mistym>
f:\foo\1234\bar.txt
<mistym>
And you're checking with your column1=1234
<ridders24>
mistym: yh its a mixture of F:\DATA\1234\1234-11\1234-11-abc-1-1.txt
<ridders24>
mistym: or could be F:\DATA\1234\ABC-1-2
<ridders24>
mistym: it will vary
<mistym>
given the first case, what are column1 and column2?
<ridders24>
column1 would be the folder "1234" and column2 would be the filename"abc-1-2"
<mistym>
What about the other one?
<ridders24>
mistym: same
<mistym>
column1 would be "1234-11" and column2 would be "1234-11-abc-1-1.txt"
<mistym>
?
<mistym>
Or rather that minus the .txt?
frangiz has joined #ruby-lang
<ridders24>
column1 would just be four digits so "1234"
<mistym>
Even though that's not the directory name?
<ridders24>
well its part of the path to get to "1234-11-abc-1-2"
<mistym>
Right, but it's not all of the path! That changes things, since you can't just take a look at the immediate directory `path` is in and see whether it exactly matches column1
<ridders24>
mistym: sorry i thought it matched the path

frangiz_ has joined #ruby-lang

mistym: not all the folders are like that though, so shouldnt i still have had some results back?
<ridders24>
mistym: or is it becuase they all start f:\DATA?
<mistym>
ridders24: Yeah, since there's more than one directory - so File.dirname is returning something like "DATA\1234-11". And that, of course, doesn't equal "1234-11".
<ridders24>
mistym: what if i did Find.find("F:/DATA/") do |path|
<ridders24>
mistym: although i still wont get all results
<mistym>
That will help, but of course some of them are still more than one level deep.
<mistym>
If you don't care about getting some potential spurious results, you could do File.dirname(path).include? column1
<mistym>
include? checks to see whether a string is contained somewhere in another one.
<mistym>
For instance, 'foobar'.include?('foo') returns true.
<ridders24>
mistym: i changed F: to F:/DATA, to see if i got any results. however nothing is in output.txt
