Go source code linter providing checks for license headers.
For installation you can simply use go get.
go get github.com/denis-tingajkin/go-header/cmd/go-headerTo configuring .go-header.yml linter you simply need to fill the next fields:
---
temaplte: # expects header template string.
tempalte-path: # expects path to file with license header string.
values: # expects `const` or `regexp` node with values where values is a map string to string.
const:
key1: value1 # const value just checks equality. Note `key1` should be used in template string as {{ key1 }} or {{ KEY1 }}.
regexp:
key2: value2 # regexp value just checks regex match. The value should be a valid regexp pattern. Note `key2` should be used in template string as {{ key2 }} or {{ KEY2 }}.Where values also can be used recursively. Example:
values:
const:
key1: "value"
regexp:
key2: "{{key1}} value1" # Reads as regex pattern "value value1"- YEAR - Expects current year. Example header value:
2020. Example of template using:{{YEAR}}or{{year}}. - YEAR-RANGE - Expects any valid year interval or current year. Example header value:
2020or2000-2020. Example of template using:{{year-range}}or{{YEAR-RANGE}}.
go-header linter expects file paths on input. If you want to run go-header only on diff files, then you can use this command:
go-header $(git diff --name-only | grep -E '.*\.go')Create configuration file .go-header.yml in the root of project.
