I have an issue, I wouldn't say it's a problem at the moment, but I can see how it could turn into one in the future.
I'm following some tutorials from Ruby, so I have a folder with a bunch of different files. In one of them, I was studying Hashes, and they showed that I could name its keys like :key. No problem so far.
The issue came when I was studying Classes and I had to declare the class attributes, IntelliSense (I guess, maybe it is another extension) would recommend code completion with the keys I declared in that Hashes ruby file.
So I tested some stuff and:
It wasn't unique to that file (of course).
It's not just in hashes, it will recommend any type of :attribute I create. Whether it is classes or hashes (which is what I have tried so far), it doesn't matter.
It isn't unique to that folder. If I have the files in different folders, with different depths let's say, it will still appear.
The only way I found to get rid of that was to erase the file, and that's no solution at all.
I guess my precise question is: How can I disable that code completion characteristic?
You can ignore file or folder in code completion by adding it to files.watcherExclude setting.
Files must be closed in editor: if ignored file is open, it will still be used for autocomplete.

I use Poedit in a project for localization. Whenever I change an entry with poedit, it reorders all elements. I think it reorders the elements according to their line number and file but since I´m working with many coders on this project, poedit must not reorder all elements to avoid unneccessary line changes in the repository. Does anyone know how to achieve that?
Poedit never, under any circumstances, reorders content of the file when you “change an entry”. Files are always saved in the order they had when loaded, and it’s been like this since the very first version.
I have two explanations:
Either you’re confusing content of the file with the view presented in Poedit (where you can select your preferred display order in the View menu), in which case just change the display to whatever you like. But this seems unlikely.
Or you’re talking about not “changing an entry” in the file, but updating the PO file from source code. If that’s the case, it’s possible that you or some of your coworkers are using some very old version of Poedit. The fix would be to update to the current version, because the scan order was fixed to be stable across platforms in v1.6.5 1.3 years ago.
If it’s neither, you need to describe the issue reproducibly.
Commonly I have written programs that have multiple classes in one .rb file. Similarly I have updated programs that use multiple classes, however, each class is in its own .rb file. I can assume that having them in different files would make it easier for a team to all work together or to split work up. But in almost every project I have been assigned I have put all the classes in one file. What is the major advantage or disadvantage of using one file vs multiple and which is better 'ruby' etiquette?
Well, you've already got one great reason: "...having them in different files would make it easier for a team to all work together or to split work up."
Another reason is organization. Suppose I want to know where the User class is defined. If there are a bunch of files and one is named user.rb, that's a pretty good clue. If there are a bunch of files and none of them is named user.rb I have to start hunting through files, or use a file search utility, and my time is wasted.
Furthermore, if I'm reading a file and it says require "user" at the top, I know automatically that this file probably needs something called User. If it says require "script" at the top, I have no idea what it's loading, or what's in there that this file needs, so I have to go digging around, and my time is wasted.
A third reason is encapsulation. Keeping code in memory has real performance implications. If there are a dozen different classes in script.rb and I do require "script", then I'm loading all of those classes, even if I only want User. Not to mention your tests—and thereby your entire workflow—run a lot faster if they only have to load the things they actually need.
I'm not sure if this is the correct place to post this question because I have a hunch that the behavior I witness will also be observed using other methods. But anyway, here it goes.
I have a VBscript that contains code like this:
For Each objFile In colFiles
...

I've been running this code for quite some time on many different systems. I never bothered to order the files alphabetically. But today I found out by accident that the logic of my program depends on it. I ran the code on a new system (under Citrix) and the files were returned in a seemingly random order.
Does anybody know why Windows sometimes returns the files sorted alphabetically while sometimes it doesn't?
Added note: It might be relevant to note that the script as well as the input folder are on a network share (where my script outputs randomly ordered files).
Ordering is not supported for FileSystemObject. See KB 189751 http://support.microsoft.com/kb/189751/en-us
Also check out an answer on how to deal with that on SO Order of Files collection in FileSystemObject
The docs do not specify an ordering. Thus, you cannot depend on it to have an order. The Files property needs to ask the underlying file system for the files, and then gives it to you as it, without any processing. If that file system happens to return the files in order, that's great. If not, you'll have to sort it. Regardless of whether it is in order, you should always order it if you expect it in a certain order because the implementation may change tomorrow (as you've just witnessed).
It depends on what data structure you are looping through.
You will obviously get a different order if you use foreach loop in an array and a hashset, for example.
Personally, I don't know anything about VB. But it does work this way in C#.
I am currently developing some functionality that implements some complex calculations. The calculations themselves are explained and defined in Word documents.
What I would like to do is create a hyperlink in each code file that references the assocciated Word document - just as you can in Word itself. Ideally this link would be placed in or near the XML comments for each class.
The files reside on a network share and there are no permissions to worry about.
So far I have the following but it always comes up with a file not found error.
file:///\\165.195.209.3\engdisk1\My Tool\Calculations\111-07 MyToolCalcOne.docx
I've worked out the problem is due to the spaces in the folder and filenames.
My Tool
111-07 MyToolCalcOne.docx
I tried replacing the spaces with %20, thus:
file:///\\165.195.209.3\engdisk1\My%20Tool\Calculations\111-07%20MyToolCalcOne.docx
but with no success.
So the question is; what can I use in place of the spaces?
Or, is there a better way?
One way that works beautifully is to write your own URL handler. It's absolutely trivial to do, but so very powerful and useful.
A registry key can be set to make the OS execute a program of your choice when the registered URL is launched, with the URL text being passed in as a command-line argument. It just takes a few trivial lines of code to will parse the URL in any way you see fit in order to locate and launch the documentation.
The advantages of this:
You can use a much more compact and readable form, e.g. mydocs://MyToolCalcOne.docx
A simplified format means no trouble trying to encode tricky file paths
Your program can search anywhere you like for the file, making the document storage totally portable and relocatable (e.g. you could move your docs into source control or onto a website and just tweak your URL handler to locate the files)
Your URL is unique, so you can differentiate files, web URLs, and documentation URLs
You can register many URLs, so can use different ones for specs, designs, API documentation, etc.
You have complete control over how the document is presented (does it launch Word, an Internet Explorer, or a custom viewer to display the docs, for example?)
I would advise against using spaces in filenames and URLs - spaces have never worked properly under Windows, and always cause problems (or require ugliness like %20) sooner or later. The easiest and cleanest solution is simply to remove the spaces or replace them with something like underscores, dashes or periods.
Sadly, a project that I have been working on lately has a large amount of copy-and-paste code, even within single files. Are there any tools or techniques that can detect duplication or near-duplication within a single file? I have Beyond Compare 3 and it works well for comparing separate files, but I am at a loss for comparing single files.
Thanks in advance.
Edit:
Thanks for all the great tools! I'll definitely check them out.
This project is an ASP.NET/C# project, but I work with a variety of languages including Java; I'm interested in what tools are best (for any language) to remove duplication.
Check out Atomiq. It finds code that is duplicate that is prime for extracting to one location.
http://www.getatomiq.com/
If you're using Eclipse, you can use the copy paste detector (CPD) https://olex.openlogic.com/packages/cpd.
You don't say what language you are using, which is going to affect what tools you can use.
For Python there is CloneDigger. It also supports Java but I have not tried that. It can find code duplication both with a single file and between files, and gives you the result as a diff-like report in HTML.
See SD CloneDR, a tool for detecting copy-paste-edit code within and across multiple files. It detects exact copyies, copies that have been reformatted, and near-miss copies with different identifiers, literals, and even different seqeunces of statements.
The CloneDR handles many languages, including Java (1.4,1.5,1.6) and C# especially up to C#4.0. You can see sample clone detection reports at the website, also including one for C#.
Resharper does this automagically - it suggests when it thinks code should be extracted into a method, and will do the extraction for you
Check out PMD , once you have configured it (which is tad simple) you can run its copy paste detector to find duplicate code.
One with some Office skills can do following sequence in 1 minute:
use ordinary formatter to unify the code style, preferably without line wrapping
feed the code text into Microsoft Excel as a single column
search and replace all dual spaces with single one and do other replacements
sort column
At this point the keywords for duplicates will be already well detected. But to go further
add comparator formula to 2nd column and counter to 3rd
copy and paste values again, sort and see the most repetitive lines
There is an analysis tool, called Simian, which I haven't yet tried. Supposedly it can be run on any kind of text and point out duplicated items. It can be used via a command line interface.
Another option similar to those above, but with a different tool chain: https://www.npmjs.com/package/jscpd
