  • How to copy a file using Paperclip

    - by CalebHC
    Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Speaking of copying, is there an easier way of copying a whole model including all of its has_many relationships? Sorry for the second question but it kind of fits! :) Thanks

  • Get scanner to include but ignore quoted text?

    - by user1086516
    Basically my problem is this, I need to parse text where , is the delimiter but anything in " " quotes should not be checked for a delimiter. Is this what the Scanner.skip method is for? I would check it myself but I don't understand how to write a regex pattern in java where the token is something in between two " ". I also want to include any quoted text in the proper token which was delimited by the valid ,.

  • How would one go about adding (minor) syntactic sugars to Java?

    - by polygenelubricants
    Suppose I want to add minor syntactic sugars to Java. Just little things like adding regex pattern literals, or perhaps base-2 literals, or multiline strings, etc. Nothing major grammatically (at least for now). How would one go about doing this? Do I need to extend the bytecode compiler? (Is that possible?) Can I write Eclipse plugins to do simple source code transforms before feeding it to the standard Java compiler?

  • Syntax highlighting on iPhone Text-Editor

    - by pbcoder
    Hi, I want to write a simple text editor for iPhone with syntax highlighting support for c,c++. But the problem is, I dont't know how to do this. The first solution I was thinking about, was to go over the text and highlight keywords when the value of the UITextView has changed, but I think that if I got more than 1000lines of code that doesn't work very well. Thanks for help!

  • conditionally enabling constructor

    - by MK
    Here is how I can conditionally enable a constructor of a class : struct Foo { template<class T> Foo( T* ptr, boost::enable_if<is_arithmetic<T> >::type* = NULL ) {} }; I would like to know why I need to do the enabling via a dummy parameter. Why can I not just write : struct Foo { template<class T> Foo( boost::enable_if<is_arithmetic<T>, T>::type* = NULL ) {} };

    - by Jared
    is there any local file manipulation that's been done with javascript? i'm looking for a solution that can be accomplished with no install footprint like requiring AIR. specifically, i'd like to read the contents from a file and write those contents to another file. at this point i'm not worried about gaining permissions, just assuming i already have full permissions to these files.

  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

  • Trying to provide a global logging function

    - by Gekitsuu
    I typically write my scripts with a structure like s #!/usr/bin/python import stuff def do_things(): print "FOO" def main(): do_things() if __name__ == "__main__": main() The problem I have is I'd like to have a logging function that is defined globally and I"m not really sure how to do this. I tried a decorator function but if I define it in main I can't call it from other functions in the script. It seems like something that should be easy to do but not something I have experience with.
