The chất lượng of code development has several aspects, so adhering lớn certain rules when writing code is important. This applies not only to lớn formatting but also to many other factors, determined by the corresponding coding convention for the selected programming language & the selected development framework.

Bạn đang xem: Coding conventions

The importance of adhering lớn a coding convention, as well as a unified style of writing code, and following certain rules when building an architecture, is hard khổng lồ overestimate.

These are important points in the development of code, & in many ways, they are the key lớn the success of the hàng hóa in the future.

Let's see why, where, and when khổng lồ use the coding conventions.

What is Coding Conventions

The code formatting standard is generally accepted & used by a group of software developers to lớn uniformly mô tả code. The purpose of adoption và use of the standard is lớn simplify the understanding of program code by a person, and minimize the load on memory, thinking, & vision when reading a program.

An example of a coding standard is a phối of conventions adopted in any common printed work in a language (for example, the C standard for coding, which received the acronym K&R, comes from the classical books of C by Kernighan và Ritchie). Another example is a widely used library or API (for example, the distribution of the Hungarian notation was clearly influenced by its use in the Windows API, and most coding standards for Python use, to lớn one degree or another, the PEP standards).

Language developers also release detailed coding guidelines. For example, Microsoft’s C # coding standards and Oracle’s Java coding standards have been released. The coding manner proposed by the developer or accepted by well-known sources is more or less supplemented và refined in corporate standards.

Typically, a coding convention standard describes:

ways of choosing names và the used case of characters for variable names và other identifiers:writing the type of the variable in its identifier (Hungarian notation) và a cast of characters (lower, upper, "camel", "camel" with a lowercase letter), the use of underscores lớn separate words;indentation style for logical blocks - whether tabs are used, indent width;a method for placing brackets bounding logical blocks;the use of spaces in the design of logical and arithmetic expressions;comment style and the use of documentary comments;variable, class and file naming conventions;statement style and best practices of their usage;file organization;declaration of classes and interfaces;programming practices.

Outside of the standard, the following are implied:

lack of magic numbers;restriction of the kích cỡ of the code horizontally (so that it fits on the screen) và vertical (so that all the code of the file is held in memory)as well as a function or method to the form size of one screen (for some programming languages).

Why use coding Conventions

Coding standards are important for software developers for several reasons:

40% - 80% of the total cost of software is spent on its maintenance.Software is almost never fully supported by its original author.Coding standards improve software readability by allowing developers khổng lồ understand new code faster & better.Like any other product, the software must be "well packaged" và clean.

As the developers of aryannations88.com Systems note, “The project should be written in the same style. This is necessary both lớn improve support and tốc độ up involving new developers & to prevent the writing of new bicycles or the use of unnecessary patterns in the project, where it is not needed at the moment."

In our experience, the coding convention improves code readability, facilitates the introduction of new developers on the project, and simplifies code writing, because there is an understanding of in what style it should be written, và therefore less refactor later (if standards are well written with architecture and structure).

The main reasons for using the coding convention are as follows:

The same rules for writing code make it easy for other colleagues to understandIt is easier lớn understand the code in a year or 5 without the need khổng lồ read each termYou always know where certain classes & files are in a huge project

In general, this is the cleanness of the code, which simply speeds up the work. This can be compared to lớn a desktop: if everything is neatly arranged, it is easy to work. If there is a mess, then every little thing takes a long time lớn find.

Very often Coding Conventions for each team are different, & sometimes very different from project to project. We need them so that other developers can easily figure out the code và in general, the code written by different team members looks the same within the project và is maintainable và supportable.

For various programming languages, there are coding conventions. These coding conventions are not absolute. In each project and in each company, standards can be developed for the coding convention. Here is a chart for example:

Where và When khổng lồ use Coding Conventions

It is worth noting that coding convention is not just formatting.

Answering the question of when lớn use the coding convention, the easiest option is when writing the code itself. This provides for familiarization of all project participants with the convention và coordination of all necessary requirements.

*

Convention coding must be applied both by a single developer & by a development team.

Regardless of the qualifications of the developers, they must use the coding convention; this makes the software development process more stable & the code turns out to be better.

Note that during the Software peer review, compliance with the coding convention is very important.

The verification process of the coding convention can also be carried out during refactoring. This improves code readability và makes the whole project more unified.

Standardization of coding conventions can be adopted at the following levels

Conclusion

Our developers from aryannations88.com Systems work according to conventions established và agreed upon with customers.

This applies khổng lồ various programming languages và various frameworks.

aryannations88.com Systems project managers and developers usually work with the following codebase options:

fully fit into the customer development environment và integrate into the team, accepting the coding convention as a wholeif the customer has not chosen a coding convention, our developers will always advise the best coding convention for this projectif required, our developers can make changes to a certain coding convention and accept it for developmentif required (in very rare cases), our developers can write the necessary coding convention for the selected project, & follow it to conduct the project

aryannations88.com Systems follows a high code development culture. This applies khổng lồ strict adherence lớn the coding convention, as well as building a clear project architecture, developing unit tests, and adhering khổng lồ agile (scrum) methodologies.

We always vì the code correctly so that it can be supported in the future, is easy lớn understand và it is easy to lớn complement the team with new developers.
