Overview ¶
Package swipe is a code generation tool that automates the creation of repetitively used code. Configuration parameters are presented in Swipe as parameters of the Golang function, using explicit initialization instead of global variables or reflections.
Swipe generates code using an option: a function that calls functions that define the generation parameters. Using Swipe, you describe the generation parameters in the option, and then Swipe generates the code.
1. The "function as an option" approach is used to configure generation.
2. All ads that are not related to options found in the file will be copied to the generated file.
3. Function with a `swipe.Build` option inserted in the body. `swipe.Build` will not be transferred to the generated code.
If you want the generate code, you can run:
swipe /pkg/your_package/your_file.go

func ConfigEnv ¶
func ConfigEnv(...ConfigEnvOption) Option
ConfigEnv option for config generation. To generate a configuration loader, you can use the `swipe.ConfigEnv` directive. The first parameter is a pointer to the configuration structure, and the second parameter is the name of the configuration loader function.
The directive can work with all primitives, including datetime, and an array of primitives. The directive supports nested structures. To use the default value, just specify it as a value in the structure.
Default func name is `LoadConfig`.
You can use structure tags to control generation:
env - name of environment var, options: `required`. flag - name of flag, enable as the console flag. desc - description for String function.
