decorder's Introduction

Decorder

A declaration order linter for golang. In case of this tool declarations are type, const, var and func.

Rules

This linter applies multiple rules where each can be disabled via cli parameter.

rule	description	cli-options
declaration order	Enforces the order of global declarations (e.g. all global constants are always defined before variables). You can also define a subset of declarations if you don't want to enforce the order of all of them.	* disable check: `-disable-dec-order-check` * custom order: `-dec-order var,const,func,type`
declaration number	Enforces that the statements const, var and type are only used once per file. You have to use parenthesis to declare e.g multiple global types inside a file.	disable check: `-disable-dec-num-check`
init func first	Enforces the init func to be the first function in file.	disable check: `-disable-init-func-first-check`

You may find the implementation of the rules inside analyzer.go.
