code-translation

I would like to transform java source code at compile time just before passing the source code to the compiler. In other word I would like to create a preprocessor able to transform "bla bla bla" into any other code such as: new MyClass("bla", 3) My actual motivation is to do string encryption, as explained here Some people suggest writing custom annotation processors but as far as I understand annotations: they can be used to generate new class file, but not to transform existing code before being passed to compiler they seem to work at package, class or method level, but not method body

Is there a relatively quick program out there to accomplish at least the basics of this? Just a few regexes? I'm willing to do some manual conversion, but this is a pretty big set of scripts. Lyndon White Updated Now several (4) years later this (almost certainly) can be done; though certainly not with RegEx. I suggest future readers look to @Piotr Dabkowski's answer. . Or some of the other answers. (I don't know having not tried them) Original Answer Hm this is a hard one. The definition of a compiler is translates from a higher level language to a lower level language. eg python to machine

This code is part of AjaxControlToolkitSampleSite . To be exact, it is in the AsyncFileUpload control: AsyncFileUpload1.UploadedComplete += new EventHandler<AsyncFileUploadEventArgs>(AsyncFileUpload1_UploadedComplete); How can I translate this to VB.NET? Here you go: AddHandler AsyncFileUpload1.UploadedComplete, AddressOf AsyncFileUpload1_UploadedComplete Alternatively, within your code, you can select the AsyncFileUpload1 control from the left-hand dropdown list (just above the code) and then select the UploadComplete event from the right-hand dropdown list. This will automatically create an

Given a set of Java source code files, how can I compile them into one or more JavaScript files that can be used with hand-crafted JavaScript? GWT is one option, but every example I've seen so far is aimed at building fancy websites. The simple use case of just converting Java source to Javascript that can be used together with handcrafted JavaScript hasn't been well-documented . I started a thread on the GWT mailing list on this subject, but opinions seem to be mixed on whether this is even feasible. One person gave a very useful tip, which was to check out GWT-Exporter . The problem is that

I was asked to write a code translator that would take a Python program and produce a C program. Do you have any ideas how could I approach this problem or is it even possible?

I'd like to save some simple data. On the iPhone, I can do it with NSUserDefaults in Objective-C. What is the similar command here in Android? I'm just saving a few variables, to be reused as long as the application is installed. I don't want to use a complicated database just to do that. christian Muller This is the most simple solution I've found: //--Init int myvar = 12; //--SAVE Data SharedPreferences preferences = context.getSharedPreferences("MyPreferences", Context.MODE_PRIVATE); SharedPreferences.Editor editor = preferences.edit(); editor.putInt("var1", myvar); editor.commit(); //-
