Issue #10630 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Rejected

It seems an Erubis specific bug.
ERB hasn't had that issue.

Hello, 

First of all, is this a good place to report Erubis bugs? Their GitHub repo is stale (no action since 2011) and I was suggested by the Rails team to try here.

GitHub ticket: https://github.com/kwatch/erubis/issues/6
Repro example: https://github.com/rails/rails/issues/18098#issuecomment-67667400

---------------------

It seems that ERB (Erubis) doesn't handle well tags embedded within another tag. My goal is to produce ERB code with some values prefilled in the first pass.

Input ERB code:

```
    <div>
        <%%= Results: <%= 'first' %> | <%= 'second' %> | <%= 'third' %> %>
    </div>
```

Produces the following output:

```
    <div>
        <%= Results: <%= 'first' %> | second | third %>
    </div>
```

Expected output is:

```
    <div>
        <%= Results: first | second | third %>
    </div>
```

The first nested ERB tag is skipped. The same happens when there is just one block nested.

This is reproducible in Rails v4.1.8, which is using Erubis v2.7.0.
