Pre-commit installation fails

[sgabenov]

It seems like, if i use this tool with pre-commit, it tries to search Go files not in pre-commit .cache directory, but from root path of the repo. Could you please check with some empty git repo to use this pre-commit configuration to get same errors.

After creating .pre-commit-config.yaml and commiting files \ executing pre-commit run

repos:
- repo: https://github.com/hashicorp/copywrite
  rev: v0.16.4
  hooks:
    - id: add-headers
    - id: check-headers

have such error:

Add copyright headers....................................................Failed
- hook id: add-headers
- exit code: 1
go: cannot find main module, but found .git/config in /Users/gabenov/git/sandbox/pre-commit
	to create a module there, run:
	go mod init

or after executing go mod init pre-commit

Validate copyright headers...............................................Failed
- hook id: check-headers
- exit code: 1
no Go files in /Users/gabenov/git/sandbox/pre-commit

version: pre-commit 3.3.2

Getting the same error. I do have Go installed, but I'm using it in .NET project (with some Terraform).

I installed the tool using homebrew, so I was expecting the pre-commit-hooks to run the installed binary instead of doing go run.

Hey folks!

Before I jump into troubleshooting, it sounds like there may be some ergonomics issues with using the Golang-mechanism for installation. To make things more idiomatic with how you would expect pre-commit hooks to work, would it be preferable to have the hook install the binary from GitHub releases or expect it to already be in the user's $PATH?

[bloudraak]

I expected it to use the copy I installed. That being said, it would be preferable if the hook installed the binary, so it can work on any supported platform, including Windows (which some teammates use).

I think, that pre-hook should not install golang itself. The better is to distribute 'copywrite' as a prebuild binary, as it said, it could be executed on each platform.
