Gnoweb: list available realms and packages in the HOME

[moul]

It could be a new helper ({{ range .ListRealms }} and {{ range .ListPackages }}) that remains resource-free when not utilized in the template. This way, we can have the default template for local development with the option to disable it on testnets. It might also be useful to enable it on staging.

Note that also there's no package query implementation in vm/handler.go. There's a TODO but I'm not sure the initial purpose of this method was to list all packages. The comment mentions package's file...

gno/tm2/pkg/sdk/vm/handler.go

Lines 116 to 120 in 3ade982

	// queryPackage fetch a package's files.
	func (vh vmHandler) queryPackage(ctx sdk.Context, req abci.RequestQuery) (res abci.ResponseQuery) {
	res.Data = []byte(fmt.Sprintf("TODO: parse parts get or make fileset..."))
	return
	}
