Nothing about the original text is maintained after the operation. With a simple find and replace, the target text is found and blindly replaced with the desired new text. Access to the feature usually lives in a menu somewhere - typically the Edit menu since it is an editing function. Most users of a modern IDE or text editor will be familiar with find and replace functionality. keep the semicolon on the end because this example is Java.I’ll have to remove set and then change the case of the next character of the method name.change the method name into the property/member name that needs to be assigned a value.insert an assignment operator prior to the value.keep the single method parameter to use as the assignment value, but get rid of the parentheses that surround it.I know the member name I’ll be assigning a value to is embedded in the setter method name. For this example, I want to change the method call to be an assignment statement.
ANDROID STUDIO FIND AND REPLACE CODE
The first step here is to understand what the desired code needs to look like. Now, I need to craft a regex that manipulates existing lines to get our desired code. Aside from that, we can make ourselves more productive by practicing our regex skills! It wouldn’t take too long to do it by hand (again: at least not for this case - only four lines of code), but doing it that way is tedious and boring. To get to my target code from the existing code, I need to remove some characters in a few places, add the assignment operator, and change the case of the member name embedded in the setter method name. So, here is the code that I’m targeting as a result from my example above: It’s probably just as fast, or faster, to just make the change by hand for small cases. I can type out every line of code or I can save myself some time and use regex replace to make the task faster.Īgain, I don’t necessarily recommend using regex replace for so few lines on a regular, pun intended, basis. Let’s assume I would like to eliminate the setters and use direct member access (but let’s not argue about why we made that choice our senior has issued the directive). Regular Expressions are, more or less, universal, but how you enable regex in your find/replace dialog will likely differ depending on the editor. It shouldn’t take much effort to find the specifics for your favorite editor or IDE. Well, you can do it manually in 10 or 15 minutes or you can get it knocked out in rapidly using regex find/replace.įor these examples, I’m going to cover how I would do this in my favorite IDE, IntelliJ (Android Studio). For a slightly more realistic context, imagine you have a length list of constants that you need to make available as symbols for your application. The example I’ll use below is not necessarily a great case for using this approach - I want to be clear about that. The situation I’m talking about isn’t a refactoring task that is supported by the refactoring tools built in to most IDEs so I enlist that double-edged sword, regular expressions, to make things easier and faster. I frequently encounter situations where I have a lot of code that needs to be refactored.
