V was originally designed as a language with very strict coding rules. This avoids a lot of problems when code is written in different styles, which makes maintaining large codebases a big problem.
As with Go, V has a special built-in code formatter, vfmt which brings the code to a single style.
Source code organization
V is a very modular language, so any programs should be organized into modules, which are located in separate folders within the project. You can read more in the Modules article.
The root of all modules can be either the project root or the special src/ folder.
project/ ├── src/ │ ├── module1/ │ │ ├── module1.v │ │ └── module1_test.v │ └── module2/ │ ├── module2.v │ └── module2_test.v └── v.mod
At the root of the project, there should be a
v.mod file with a description of the module.
Unlike Go, V also requires structs/functions/etc. naming in one allowed style.
- Structures, interfaces, types -
- Functions, methods, variables, constants -
If structs/functions/etc. are not named according to these rules, the compiler will throw an error.
