help: lint tool suggestion

[ppd0705]

I make a same stupid error many times. the error is like the code below

a := decimal.NewFromString("123")
b := decimal.NewFromString("345")
a.Sub(b)
// wanted:  a = a.Sub(b)

I often forget a = . is there any lint tool for this situation ?

govet has an unusedresult check. https://golangci-lint.run/usage/linters#govet

thanks for your reply. the document is to simple to understand, do your have a config template ?
I tried the conf below, it doesn‘t work

lint:
  govet:
    settings:
      unusedresult:
        stringmethods:
          - (github.com/shopspring/decimal.Decimal).Sub

@ppd0705 that looks like the funcs formate, stringmethods should just be Sub

lint:
  govet:
    settings:
      unusedresult:
        funcs:
          - (github.com/shopspring/decimal.Decimal).Sub
        stringmethods:
          - Sub
