Você está enfrentando conflitos de nomenclatura de variáveis em seu projeto. Como você pode garantir consistência e clareza?

Each language has its naming convention you have to adhere to. Standards ask you to stick on a case style, avoid keywords/special chars, or else you get errors. Unit testing does not detect naming convention bugs. To detect naming convention inconsistencies you may use static analysis (linters), code review or a custom script where you define the rule, check the names and report violations. I worked in a project where I did static analysis visually, reading code written by many developers of different levels, along the years. It was hard to understand what a crypted, abbreviated or confusingly, too shortly named variable does in a very technical code, with no comments added. Team leaders were doing a code review and approval for our fixes.

Adopting a naming convention simplifies collaboration because everyone is working within the same structure, so you don’t have to waste time figuring out what a variable represents or why it’s named a certain way. It also makes code maintenance easier since you can quickly scan and understand it without getting tripped up by inconsistent naming. I think it’s less about which convention you choose and more about sticking to one consistently especially when working with a team.

Descriptive variable names are the best way to highlight the significance of a value in a program. By using clear and specific names, you can avoid duplicating variable names and maintain consistency throughout your code. This practice not only makes the code easier to understand but also simplifies debugging, especially when changes are made during development. Ultimately, descriptive names add significant value to the overall quality and readability of your code.

Imagine you work in a very technical enterprise application where code is developed years in lot of releases and has lot of features. If variables are not well defined you are lost in the forest with no indicators where to go next. I encountered and I was also tempted to use and being corrected following types of mistakes: case sensitivity (var1, Var1, VAR1), similar names (num, nums, t1, t2) and single letter vars like x, y or i, j, k used in loops in different blocks of code (var shadowing, which var you reference). Nowadays, with powerful tools available, I think code is documented and well commented. I corrected collaborative code where I had also to correct and comment the code, to make it more readable and without inconsistencies.

As a bug fixing developer, I encountered the aspect of limiting the global scope of variables in the code. I corrected many conflicts and inconsistencies generated by using same variable name in loops in different blocks of code, or scope overlapping (nested scope). I had hard times reading a not commented collaborative code containing lots of iterator vars named i, j, x, t, n, nr, nrs that I had to detect what they do and what they should do. There were a lot of bugs and memory issues generated by the fact that vars were named in a hurry in the beginning of the creation of the app that became huge over the years and with a lot of versions. This is why today's rules and tools were invented, to help writing fast a clean&clear code.

Keep variables tightly scoped to where they’re needed. This minimizes conflict and makes your code more modular. Localized variables reduce the chance of accidental overrides, making debugging simpler and the code more maintainable.

Don’t let messy naming fester. Regularly revisit and refactor variable names to ensure they remain relevant and consistent with project evolution. It’s like tidying up your workspace—it keeps things efficient and prevents headaches down the road.

Naming doesn’t have to be a solo endeavor. Involve your team in the process, especially when variables impact shared code. Collaboration ensures that naming conventions reflect collective understanding and that no one is left puzzled by ambiguous

My coding experiences included static analysis, to detect the root cause of a bug that it proved to be a var naming. I also implemented solutions for bugs implying defining or renaming variables for better readability or consistency. I had a reviewer that verified and approved my solution. I also had a mentor that guided me through the immensity of specific functional tech terms of the app logic and design. Peer reviewing was present in all projects I worked, regardless the company.

Documenting naming conventions makes it easier to manage code and capture the reasoning behind key decisions. This is especially helpful for new developers, as it gives them a clear guide to follow, ensuring they use the correct standards and conventions. In large codebases, where it's nearly impossible to remember every convention, documentation becomes essential for consistency and clarity. It not only helps maintain order but also provides a point of reference that can prevent misunderstandings and conflicts in the process.

This is an important part, and I had the occasion to work in a team dealing with a not documented and not commented code. It is very time consuming, and not always successful, if you want to correct a bug, because you don't have clues to understand what code does and most important what it should do. Along with version control tools becoming more powerful and lots of IntelliSense like tools, coding bad practices were less frequent. And with the help of AI, less worries: today GitHub Copilot can write, correct, comment code, and can also automatically create the documentation for your code. Developers double check and approve the logic solution but don't have to care about variable definition naming correctness at all, it's accurate.

Create a living document that outlines your naming conventions and reasoning behind key decisions. This way, everyone—current and future team members—can refer back to it, ensuring ongoing consistency and reducing the need for guesswork.
