I am having trouble including a module in a namespaced class. The example below throws the error uninitialized constant Bar::Foo::Baz (NameError). What basic piece of Ruby knowledge am I missing here?
module Foo
module Baz
def hello
puts 'hello'
end
end
end
module Bar
class Foo
include Foo::Baz
end
end
foo = Bar::Foo.new

I'm creating a bookmarklet and of course I'd like to use jQuery. But, if I include jQuery (append a script-tag to head) on a site, will the site itself work anymore, if it has some other js on?

I would like to ask if there is a way to include the total number of rows, as an additional column, in the returned result sets from a TSQL query using also the Row_Number (SQL 2005) command.
For example, getting the results set from a query against Book table in a form similar to this:
RowNum BookId BookTitle TotalRows
--------------------------------------------
1 1056 Title1 5
2 1467 Title2 5
3 121 Title3 5
4 1789 Title4 5
5 789 Title5 5
I'm trying to return a IDictionary<int,int> (created with dict tuplist) from F# to C#, but it says that I must include a reference to FSharp.Core because of System.Collections.IStructuralEquatable.
I've tried returning a Dictionary<_,_>(dict tuplist), but that doesn't make any difference.
I even tried Dictionary<_,_>(dict tuplist, HashIdentity.Reference), but that says that int is a struct...
Under the /usr/include directory in Linux i entered the command:
find -type f -name unistd.h which gave the following output:
./unistd.h
./linux/unistd.h
./asm-generic/unistd.h
./bits/unistd.h
./asm/unistd.h
./sys/unistd.h
my question is, what is the purpose of each unistd.h, since there is only one definiton of that file in the single unix specification ?
Thanks in advance.
In my src folder there is another folder called data which contains data1.txt and data2.txt. The application loads a graph from these files in the initialization so I want to include these files in my final jar. I use ant to produce the jar file.
I'm now doing it in a very ugly way by manually including all the required path(the gtk bundle is at D:/Tools/gtk+-bundle_2.20.0-20100406_win32):
include_directories(D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/gtk-2.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/glib-2.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib/glib-2.0/include D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/cairo D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/pango-1.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib/gtk-2.0/include D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/atk-1.0)
link_directories(D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib)
target_link_libraries(MyProgram gtk-win32-2.0.lib)
Is it possible to include the revision number or the name of the tag used for a build on an ASP.NET website when deploying with CruiseControl.net and subversion?
If I understand it correctly this means
extern void foo();
that the function foo is declared in another translation unit.
1) Why not just #include the header in which this function is declared?
2) How does the linker know where to look for function at linking time?
I have the following validation:
validates_presence_of :price, :message => "my message"
and I get the following error when the price is blank:
Price my message
Is there a way not to include the column name (price) in the message ?
I tried to do:
validates_presence_of :price, :message => "^ my message"
as suggested here, but it didn't work for me. I got the following message:
Price ^ my message
Because apparently require 'date' doesn't include the method hours or seconds etc:
undefined method `hours' for 5:Fixnum (NoMethodError)
Am I missing something? Is 5.seconds only something you can do in Rails? If so, what is the require statement I need to get this to work in a ruby script?
I want to compare the keys in a hash of parameters against an array of elements for a match.
For example:
params = {"key1", "key2", "key3"}
params_to_match = ["key2","key3"]
I could do this, but I'm sure there is a much more elegant way to acheive the same result
params.each_key{|key|
if params_to_match.include?(key.to_s)
return
end
}

My second question - Can I build DLL or something like that for my colleagues to use? I need them to be able to call methods from my "part" but do not modify or view their content. Basically just use namespace "MyNamespace" and call its methods, but I have never done anything like that.
Thanks
My Question is suppose I have a form which needs validation through AJAX. The AJAX is sending data to to a file called do_ajax_validation.php Now should I put this file in 'include' folder and name it do_ajax_validation.inc.php and bar it from direct access of the user. Or shud i put it in the directory in which the original form resides??
How to include an image inside another image in PHP? I want to do it like in twitterbackgrounds.com personalized backgroud. there is one main image and we can upload four personal images after that it will show as watermark of the main image.
There are many similar questions, but apparently no perfect match, that's why I'm asking.
I'd like to split a random string (e.g. 123xx456yy789) by a list of string delimiters (e.g. xx, yy) and include the delimiters in the result (here: 123, xx, 456, yy, 789).
Good performance is a nice bonus. Regex should be avoided, if possible.
I am using some external libraries, and i also want to include their javadocs.
I've searched on the internet, but few documentation exists for JDeveloper. The overall IDE is actually a little noon-intuitive, even though very powerful.
