If you maintain or plan to build Puppet infrastructure, this practical guide will take you a critical step further with best practices for managing the task successfully. This is a workshop style presentation, I’m going to dispense with the usual slide deck and we’ll work directly from the document which you can take away with you today. It is common to see Excel VBA code with object names such as Chart1, Sheet1, ObjectA. You can indent using the space or tab keys. ‘It is also faster than using strings since Enums are essentially a Long data type. Best Practice to Write a Clean and Maintainable Code Posted By : Harsh Soni | 31-Oct-2018. 1.3 Use field-based access. The code sample below illustrates proper code indentation and spacing. 6 Hibernate Best Practices for Readable and Maintainable Code Most code readers will be competent VBA programmers, so there’s no need to explain the code. So, if you want to be a professional developer then you must know, understand and follow the best practices of the language and should start practicing them from the very next piece of code … The best contribution to the debate, added as a comment to the editorial blog, will receive a $50 Amazon voucher. Multiple GoTo statements make it harder to read, maintain and change your code, the exception being code for error handlers (On Error GoTo statement). Indentation : The most basic aspect of maintainable code is the Readability of the code, for the code to read easily the indentation (empty space at the beginning of a line) must be appropriate. Add in-line comments to state what you’re about to do, what you have done so far, the reasoning behind decisions taken, any assumptions or need-to-knows. I use the following header block on my projects, adapt it as required. Both? Unconditionally branching from one code line to another may be handy at times, but the impact on readability is usually negative. Don’t comment on code that is clear by itself. One or two arguments is the ideal case, and three should be avoided if possible. Functions should do one thing. Make sure your variables are named meaningfully. When you isolate a function to just one action, it can be refactored easily and your code will read much much cleaner. Use both in-line (i.e., no code on the comment line) and end-of-line (placed at the end of code lines) comments. Instead of having one change affect all relevant modules, you have to find all duplicate modules and repeat that change. If you find that you need to repeat a code block, devise a procedure for it instead. It also touches on aspects of Excel VBA code flexibility and reusability. Choose a clear coding style: Keep your function and data naming consistent. Polluting globals is a bad practice in JavaScript because you could clash with another library and the user of your API would be none-the-wiser until they get an exception in production. I highly suggest you read “Clean Coder” by Robert C. Martin. A best practice for building code involves daily builds and testing, or better still continuous integration, or even continuous delivery. When you login first time using a Social Login button, we collect your account public profile information shared by Social Login provider, based on your privacy settings. Keep a definitive version of the procedure, so if you need to make changes or add more functionality, you will only need to do so in one place. Also, you must put comments where it is really required and avoid unwanted comments, for instance, you must avoid comments like While (x>10) {// starting While brace Writing maintainable code is hard. It is good practice to keep code lines less than 120 characters. VBA programs often feature named discrete entities called identifiers (e.g., variables). If your class or object name tells you what it is, do not include that in the variable name. Oftentimes duplication in code happens because two or more modules have slight differences that make it because you have two or more slightly different things that share much in common. I have only included a fraction of what you can do to write clean code. Here are a few best practices. ‘Purpose:          What (not how!) We spend more time reading code than we do writing code. Avoid ‘magic numbers’, constants, and strings for variables with unchanging values. It can be either a test driven development, pair programming or an Agile methodology like Extreme Programming. ‘Caller:              Subroutines? The DRY principle improves code reusability. ‘===============================================================, ‘Program:          What program/application is it being written for. ‘Call:                 “Assignment” or “Call” method. To avoid that and ensure maintainable Excel VBA code, here are a few things you might want to adopt while naming ‘stuff’ in your projects: Summarising critical data about significant modules, subroutines, and functions boost code readability and ensure maintainable Excel VBA code. Download for offline reading, highlight, bookmark or take notes while you read Perl Best Practices: Standards and Styles for Developing Maintainable Code. Now that you have your expectations properly set, I’m going to try and inspire you to write “the best darn maintainable code you can,” because by gosh, it’s just a swell thing to do. Review solution evaluation criteria and iterative improvement suggestions for architects and infrastructure engineers. Good neighbours help when needed but mind their own business otherwise (at least mine do). Who Should Read This Book? ... that you’ll kindly contribute by adding a tip or best practice of your own in the comments below. Emphasize best-practice code patterns for system administrators and developers. Die Technologie hat sich weiterentwickelt und Bücher zu lesen ist jetzt einfacher und bequemer als je zuvor. “Indeed, the ratio of time spent reading versus writing is well over 10 to 1. However, most scientists are never taught how to do this efficiently. Code that is not easy to isolate, reuse, and understand will not be adopted by other projects. I agree with the commonly recommended indentation of three spaces. It is a fuller version of the guidelines for writing maintainable Excel VBA code. This reduces the need for additional comments as your code speaks for itself. Change default worksheets and workbooks’ names. In the footsteps of Fowler The best book in the industry (in my opinion, and I’m not alone) is Refactoring: Improving the Design of Existing Code by Martin Fowler et al. The next step would be to brainstorm and agree on what would constitute the steps of doneness for coding. Would love your thoughts, please comment. Even for concepts that seem fundamental to the process (such as logging), there will certainly be edge cases that negate the need for one or more of these. Code Maintainablity Convention: Readability. Demonstrate declarative coding practices for Puppet novices of any type. Writing the same code more than once is not only wasteful when writing it the first time but even more so when trying to maintain it. Public media adopts the thin-column format which is more natural for humans to read. Authors Chris Barbour and Jo Rhett present best-in-class design patterns for deploying Puppet environments and discuss the The first two impede readability while strings evaluate slowly. Only be referenced by other variables (IN, i.e., right of ‘=’); Itself only reference other variables (OUT, i.e., left of ‘=’); Change default UserForm controls’ names before writing any code for them. Considering functions that represent a certain behavior, a function name should be a verb or a phrase fully exposing the intent behind it as well as the intent of the arguments. Functions? Comment on the ‘why’ and not the ‘how’. When your procedures tackle only one problem, you can edit, change, or add to them without crashing other parts of your code. Although this is a vast topic, I have limited it to only variables and functions to keep the post short. Cheers, Tony. Perl Best Practices: Standards and Styles for Developing Maintainable Code - Ebook written by Damian Conway. Code building. 1.1 Use constants for query and parameter names. The purpose of complex logic, routines, and functions must be well documented. — Robert C. Martin (Uncle Bob). It also touches on aspects of Excel VBA code flexibility and reusability. In cases where it’s not, most of the time a higher-level object will suffice as an argument. If you see a value and have no idea what it does or is supposed to do, that would be confusing on the reader’s end. If your procedure strays into doing more than its single primary job, you probably need a new one for that stray task. Anything more than that should be consolidated. Software development best practices & coding guidelines 1. The default tab indent is four spaces, but you can change that in the Visual Basic Editor (VBE) as shown below. ‘if not obvious, comment on what below block does and why it does it (not how! You should do your best to avoid code duplication. Removing duplicate code means creating an abstraction that can handle this set of different things with just one function/module/class. Once your account is created, you'll be logged-in to this account. Contents [ hide] 1 Best practices to keep your persistence layer maintainable. As a result, many are unaware of tools and practices that would allow them to write more reliable and maintainable code with less effort.
