Allow installation via go install

[edthedev]

What should it do?

The current instructions to install via go get are deprecated in the recent versions of go.

Following the steps in README.md,
go get -u github.com/wtfutil/wtfgives this error:

go: go.mod file not found in current directory or any parent directory.
        'go get' is no longer supported outside a module.
        To build and install a command, use 'go install' with a version,
        like 'go install example.com/cmd@latest'
...

Running go install (which is a great way to install command line utilities) gives this error:

 $go install github.com/wtfutil/wtf@latest
go: downloading github.com/wtfutil/wtf v0.43.0
go: github.com/wtfutil/wtf@latest (in github.com/wtfutil/wtf@v0.43.0):
        The go.mod file for the module providing named packages contains one or
        more replace directives. It must not contain directives that would cause
        it to be interpreted differently than if it were the main module.

It would be terrific to be able to install wtfutil using go install. I have found it to be a reliable way to install command line utilities, in particular.

The go version that I got these errors from is:

$go version
go version go1.21.5 linux/amd64

Seems that go install takes issue with this line:

wtf/go.mod

Line 228 in 85b3568

replace github.com/wtfutil/todoist => github.com/Seanstoppable/todoist v0.0.0-20221214042915-6505286e6b1e

Git blame suggests
c327cd3
is relevant

Maybe dependent on (or blocked by?)
wtfutil/todoist#4
?

For what it's worth, forking and removing that line (and changing the first line) in go.mod allowed me to install.

$go install github.com/edthedev/wtf@ba90358
go: downloading github.com/edthedev/wtf v0.0.0-20240520021219-ba90358e748d
go: downloading github.com/logrusorgru/aurora/v4 v4.0.0
go: downloading github
...

But it did not result in the expected wtfutil appearing in ~/go/bin.

This seems likely to be related to:

(Essentially, go has a few more expectations about where main.go should be, if we want wtf to appear in ~/go/bin (on GOPATH).
