Re: [go-nuts] Packages vs methods

[温博格]

If one is using gopls for Go support for an IDE (like vscode), with
semantic tokens enabled, the two cases are colored differently. It's
incrementally cheap, as gopls already typechecks source.

[to enable in vscode: in settings, in the gopls section,
"ui.semanticTokens": true]

I don't know that this satisfies the request for 'an easy way'

Re: [go-nuts] Packages vs methods

This ist actually a syntactical difference. Both are syntactically just
selector expressions.

So you'd need *semantic* highlighting, which not a lot of highlighters do.
One reason is performance and another is that it means highlighting might
fail for incorrectly typed (but syntactically valid) programs.

And if one does, you can tell the difference between literally anything (on
a type level) - if you are willing to rely on highlighting to tell the
difference between an import and a variable, you can also use it to
differentiate between, say, an interface and a concretely typed variable.
Or an int and a float type. Or whatever.

So in the context of the question, this strikes me as a pretty unhelpful
response. Yes obviously you can use a tool to *tell* you the difference by
performing a type check. But obviously the question was about a syntactical
way to do so.

Sure, use syntax highlighting in your favor.

Re: [go-nuts] Packages vs methods

['Axel Wagner' via golang-nuts]

If you see `foo.bar()` it is definitely a method, as a package-scoped `bar`
function would not be exported so it would not be visible in other packages.
If, on the other hand, you see `foo.Bar()`, there is no easy way to tell.
You have to know if `foo` is a variable or a package in the given scope.
