Formatting with multiple Services

[Xytrical]

As of #59, post formatting .ridl files using -fmt=true with multiple Services does not work anymore.

How to reproduce

Create a example.ridl file with the following contents:

webrpc = v1

name = example-api
version = v0.1.0

service ExampleService
  - Ping()
  - Status() => (status: bool)

service DummyService
  - Ping()
  - Status() => (status: bool)

Running the following command:

webrpc-gen -schema=./example.ridl -pkg=webrpc -server -out=./gen/webrpc/example.gen.go -target=golang

Will result in:

 format error       : failed to format generated Go source: 57:2: expected ';', found 'type'

Running the same command with version v0.14.1 works fine:

webrpc-gen -schema=./example.ridl -pkg=webrpc -server -out=./gen/webrpc/example.gen.go -target=github.com/webrpc/[email protected]

Fix

The issue is in line 60 of types.go.tmpl. Changing this:

{{- range $_, $method := $service.Methods -}}
{{ if eq $method.StreamOutput true }}

To this:

{{- range $_, $method := $service.Methods }}
{{ if eq $method.StreamOutput true -}}

Seems to fix the issue.
