enumer runtime crash due to x/tools being broken in go 1.22.0 (with workaround) #71

Open jth-0 opened 6 months ago

jth-0 commented 6 months ago

the x/tools package used by enumer causes it to generate the following error when it is built with go 1.22.0 on Mac OSX silicon.

panic: runtime error: invalid memory address or nil pointer dereference [recovered]

As you can see these errors come from x/tools not enumer

the workaround

per https://github.com/temporalio/sdk-go/issues/1382 we need to update x/tools in go mod to a later version

I edited enumer/go.mod to

module github.com/alvaroloes/enumer

go 1.17 // bumped to later version

require (
    github.com/pascaldekloe/name v0.0.0-20180628100202-0fd16699aae1
    golang.org/x/tools v0.17.0 //was v0.0.0-20190525145741-7be61e1b0e51
)

require golang.org/x/mod v0.14.0 // indirect

Awesome thanks so much :pray:

Is there a fork of this repo that is still actively developed?

I made my own fork with the above changes if anybody wants to use it: https://github.com/PotatoesFall/enumer

(I make no guarantees to keep this up until the end of time)
