What happens if we enable both gofmt and gofumpt?

[agis]

gofumpt already does everything that gofmt does (and more). So, what if in our configuration we have both formatters enabled? Does golangci-lint knows that gofumpt takes care of everything and so gofmt is redundant (and therefore does NOT execute it)?

Or do we waste unnecessary resources because both of these formatters are executed?

Thanks in advance

Hello,

gofumpt and gofmt are similar but different.

tool	format	imports order	fix imports	rewrite-rules	simplify	extra
gofmt	x	x (alphabetically)		x	x
goimports	x	x (multiple imports)	x
gofumpt	x	x (one import)			x	x
gci	x	x (customizable)

• goimports is a "variant" of gofmt without simplify and rewrite-rules but with local-prefixes to organize imports.
• gofumpt is a "variant" of goimports with extra-rules, and module-path is more limited than local-prefixes.
• gci is a "variant" of goimports with options to customize import orders.

So if you enable both gofumpt and gofmt, both will be run.

The formatters are run in a specific order to avoid conflicts:

1. gofmt
2. gofumpt
3. goimports
4. gci

If you are not using gofmt options, my recommendation is to enable only gofumpt.

I see. Thanks!
