Installation

go get -u github.com/rookie-ninja/rk-common

Quick Start

common

Utility functions mainly used with rk series of packages, including rk-gin, rk-grpc, rk-entry and etc.

Please don't add any dependency cycle with above packages.

flags

pflag.FlagSet which contains rkboot and rkset as key.

Usage of rkboot:

Receives path of boot config file path, can be either absolute of relative path. If relative path was provided, then current working directory would be attached in front of provided path.

example:

./your_compiled_binary --rkboot <your path to config file>`

Usage of rkset:

Receives flattened boot config file(YAML) keys and override them in provided boot config.

We follow the way of HELM does while overriding keys, refer to https://helm.sh/docs/intro/using_helm/ example:

Lets assuming we have boot config YAML file (example-boot.yaml) as bellow:

gin:
  - port: 1949
    commonService:
      enabled: true

We can override values in example-boot.yaml file as bellow:

./your_compiled_binary --rkboot example-boot.yaml --rkset "gin[0].port=2008,gin[0].commonService.enabled=false"

Basic rules:

• Using comma(,) to separate different k/v section.
• Using [index] to access arrays in YAML file.
• Using equal sign(=) to distinguish key and value.
• Using dot(.) to access map in YAML file.

strvals

Copied from https://github.com/helm/helm/blob/main/pkg/strvals/parser.go with some utility function.
