gclv - golangci-lint version manager

This is a version manager for golangci-lint. It works similar to pyenv or rvm where you manage multiple binaries through gclv.

Usage

There are two ways to select golangci-lint version with gclv. For other available commands and usage, use gclv --help.

Manually

Just specify the version you want to use. If it does not exist locally it will be downloaded. If it exists it will be re-linked. If it's already selected, nothing will happen.

$ gclv --select v1.42.0                                                                                                                                                      130 ↵

With golangci-lint configuration

Since golangci-lint doesn't care about unknown configuration you can specify what version you want to use in your .golangci.yml and gclv will be able to pick that up.

All you need to do is to add the key golangci-lint-version to your existing configuration file. There are two files in the examples directory that can be used to test this.

$ cd examples
$ config=golangci-1.40.yml

$ gclv --from-config $config
Switching to v1.40.0

$ golangci-lint --version
golangci-lint has version 1.40.0 built from 5c6adb63 on 2021-05-10T10:45:21Z

$ golangci-lint run --config $config

Wrapping golangci-lint

gclv also has a --run flag which can be used to determine version from a .golangci.yml configuration file and after switching to that version run golangci-lint with any additional flags.

If no configuration is passed, golangci-lint config path will be used to determine which configuration to parse version from. If the configuration found does not contain a version declaration (golangci-lint-version), whatever version currently set will be used.

$ gclv --run ./examples --config examples/golangci-1.40.yml
Switching to v1.40.0

$ gclv --run ./examples --config examples/golangci-1.43.yml

$ gclv --remove v1.41.1
