HAML parser has problems with phoenix_html `link do` helper

[Qqwy / Marten]

First and foremost: How nice that there is a HAML-parser for Elixir/Phoenix! :-)

Unfortunately, the following goes wrong:

This file (saved as templates/layout/menu.html.haml)

%nav.ui.top.fixed.menu
  .header.item
    Cyclicash
  .right.menu
    =link to: login_path, class: "item" do
      login

    = link to: register_path, class: "item" do
      register

breaks the HAML-parsing. Here is the stacktrace:

== Compilation error on file web/views/layout_view.ex ==
** (EEx.SyntaxError) web/templates/layout/menu.html.haml:11: unexpected end of string, expected a closing '<% end %>'
    (eex) lib/eex/compiler.ex:68: EEx.Compiler.generate_buffer/4

    web/views/layout_view.ex:1: Heads.LayoutView (module)
    (elixir) lib/kernel/parallel_compiler.ex:100: anonymous fn/4 in Kernel.ParallelCompiler.spawn_compilers/8

I think it chokes on the optional block-passing.

phoenix_haml isn't a haml parser and it doesn't really do much. Your issue is with calliope and should be submitted in to that project https://github.com/nurugger07/calliope. However, I can tell you that calliope doesn't support that syntax so it may be a feature request rather than a bug report.

Actually, I believe you can do it like this:

%nav.ui.top.fixed.menu
  .header.item
    Cyclicash
  .right.menu
    =link to: login_path, class: "item" do
      login
    - end

    = link to: register_path, class: "item" do
      register
    - end

You just need an explicit - end on each block.

[Edit: I realized after commenting that the link above already provided this solution.]
