I can’t believe that I had overlooked this application at first, but I’m glad that I finally started using it. So far, this is the best free Python IDE that I’ve found, and it’s a fantastic general text editor as well!
Here’s the official guide on how to set up Editra as a Python IDE:
My CS300 professor at Portland State University just wrote a fantastic blog post about things he commonly sees in student source code – it’s a great read and helpful for reflecting on your own code and best practices:
I’ve read quite a lot of student code over the years. Some of it is quite good. A lot of it is full of predictable badnesses. These notes attempt to enumerate some of this badness, so that you may avoid it.
This is pretty C-centric in its current form. However, many of its lessons are multilingual. This is a living document, so don’t expect it to be the same next time you look at it. In particular, the numbering may change if something gets inserted in the middle. It is revisioned automatically by Drupal, so feel free to point at a particular revision if you care.
And, my own pride and joy (this damn code took me forever, only because I had to do all sorts of research and testing with Regex in C#), the function that will fix relative paths in the combined CSS files by replacing them with absolute paths based on your application root:
/// CSS Only: Replaces relative paths in url(...) properties within the specified script.
/// <param name="scriptBody">The pre-combined script, passed from CombineScripts().</param>
/// <param name="scriptPath">The relative path where scripts are located (ex: ~/CSS/).</param>
/// <param name="applicationPath">The absolute application path. (ex: /ApplicationRoot).</param>
private static String FixRelativePaths(String scriptBody, String scriptPath, String applicationPath)
scriptPath = VirtualPathUtility.AppendTrailingSlash(scriptPath);
String relativeRoot = VirtualPathUtility.Combine(applicationPath, scriptPath);
Regex cssUrlReference = new Regex("(?<=url\\()(.+?)(?=\\))", RegexOptions.Singleline);
Regex invalidPathChars = new Regex("[ '\"]+", RegexOptions.Singleline);
MatchCollection urlMatches = cssUrlReference.Matches(scriptBody);
foreach (Match m in urlMatches)
String oldPath = Regex.Replace(m.Value, "[ '\"]+", "");
String newPath = VirtualPathUtility.Combine(relativeRoot, oldPath);
newPath = VirtualPathUtility.ToAbsolute(newPath);
scriptBody = scriptBody.Replace(m.Value, newPath);
I’d love to read your comments and/or questions about this code, so please feel free to post your thoughts in the comments on this post.
I’ll try to get you the full meal deal on this code as soon as I can. =)
Until Microsoft come up with an official solution there is a working workaround for this problem.
This problem only appears to affect people who have not got Visual C++ Installed.
1.) Download VS90SP1-KB971092-x86.exe from here … http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=294de390-3c94-49fb-a014-9a38580e64cb
2.) Start the installation VS90SP1-KB971092-x86.exe
3.) Wait for the error message to come up – DO NOT CLOSE THE WINDOW!
4.) Copy the temp. folder where the patch has been unpacked to a new folder, for example onto your desktop.
5.) Close VS90SP1-KB971092-x86.exe that you started in 2.)
6.) Navigate to <drive>:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools and find vsvars32.bat.
7.) Change the permissions on the file to allow everyone to edit it.
8.) Start VS90SP1-KB971092-x86.msp from within the saved folder and the process should complete.
If you want to preserve whitespace within an HTML element (div/span) without using non-breaking spaces (and therefore breaking word-wrap), add the following property to the CSS style(s) for that element:
There are more options available for this property as well:
It’s also worth noting that Safari and Chrome (well, anything rendered with Webkit, it seems) have an excellent set of development tools built-in that are very similar to the functionality of Firebug in Firefox, and even IE8 is catching up to the game with its Developer Tools window/pane.
I agree with Ian, this program is excellent. Gives you some useful information for a change (and something you can do with it) when you get the message “Cannot delete <X>: It is being used by another person or program.”
If you’ve been using Subversion for source control, I’m sure you’ve heard of this client. If not, get it immediately. It rocks, and integrates exceptionally well with Windows Explorer. (Not to mention Visual Studio, via AnkhSVN or VisualSVN)
Since Internet Explorer is the scourge of the Interwebs that will never go away, it helps to be able to test your site in multiple versions of IE, and since only one version can be installed at a time (and since IE8 Compatibility Mode doesn’t really help at all), IETester is a good solution that lets you test IE5.5, IE6, IE7, and IE8 rendering engines in the same tabbed browser. Very cool.
…But, as my coworker mentioned, Internet Explorer is pretty invasive and modifies more on your system than just the rendering DLLs, so it’s a good idea to keep a spare VM running each flavor of IE as well. VMWare Player is the free version of VMWare Workstation, which will run pre-existing virtual machines, but can’t create new ones. Since that functionality is missing from VMWare Player, you can use this site to create your own virtual machines from scratch: EasyVMX! Virtual Machine Creator.
RedGate’s description says it best: “.NET Reflector enables you to easily view, navigate, and search through, the class hierarchies of .NET assemblies, even if you don’t have the code for them. With it, you can decompile and analyze .NET assemblies in C#, Visual Basic, and IL.”
Ian Hickman’s post (6 Free Tools that every Windows Programmer should Install) suggests Process Explorer alone, which is a superior Task Manager replacement, but I’ll extend it to suggest the whole Sysinternals Suite, since it comes with so many other great utilities and includes Process Explorer along with them. One of my favorite tools besides PE is AutoRuns, which is a msconfig.exe replacement that offers a much better look at your startup apps and services.
TortoiseSVN comes with its own diff tool, but I tend to end up using WinMerge instead because it does a great job with comparing local files or differing versions of a file in source control, and integrates seamlessly with TortoiseSVN.
I’m definitely a keyboard junkie, so anything I can do to keep my hands on the keyboard is a plus. Launchy is by far my favorite application launcher for that reason. All I have to do is hit Alt+Space (you can reassign the hotkey if you like), and it brings up a prompt that allows me to launch anything on my Start Menu, and do a number of other tasks as well (launch websites, perform quick calculations, etc.). Definitely saves me a ton of time.
Of the two apps listed above, I prefer Charles, which is a paid application, but I’ve listed Fiddler as a free alternative. Both apps are proxies that log traffic between your system and the server you’re debugging (even localhost) and both provide valuable debugging information that is particularly helpful when trying to debug web services. From the Charles website: “Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).”
All three of the apps listed above are excellent full-featured text editors, but I prefer the feature set of EmEditor, which is a paid application. The killer feature that EmEditor provides which I haven’t yet found in either of the other editors is the Find *and Replace* in files. Notepad++ has a Find in Files option, but I haven’t found a Replace in Files function without opening up every single document and performing a replace in all open documents (info on that approach here: How To “Find And Replace” Words In Multiple Files).
Notepad2 doesn’t offer the same tabbed document interface that both EmEditor and Notepad++ offer, but it is an incredibly lightweight, and more importantly, self-contained executable that’s a perfect drop-in replacement for Windows Notepad (info on how to do this here: Replace Notepad with Notepad2).
Any of these apps offer syntax highlighting and are a great alternative to firing up Visual Studio when you need to make a quick edit (or on one of the *many* occasions when Visual Studio slows waaaaay down or locks up your system).
Also, I neglected to mention AutoHotkey since I haven’t used it as much as I probably could, but I can say that I’ve had a lot of luck with the AutoHotkey script iTunesAnywhere, which helps since I don’t have a keyboard with multimedia keys and for whatever godforsaken reason, iTunes *still* doesn’t natively support global hotkeys like Winamp does. (I’d switch back to Winamp, but I drank the Apple kool-aid and picked up an iPhone in January.)
