Spurious invalid indentation exception

[hlship]

When compiling the following template:

.sidebar-placeholder
    h1 Sidebar Empty
    p.lead
      | The sidebar is used when selecting certain objects or operations
      | in the main user interface. It will open when needed,
      | and can be closed using the
      button
        i.icon-chevron-left
      |  button.

which is (I believe) valid; I get an "invalid indentation" exception on line 4.

I've pasted the same text into http://naltatis.github.io/jade-syntax-docs/ and it generates my expected HTML output.

Are you indenting with tabs or spaces?
jade4j is a bit stricter with indentation than jade.js.
If the first indentation you use are two spaces, you have to use two spaces in the complete file.

I'm indenting with two spaces.

Are you developing on Windows or Mac/Linux? I'm wondering if there's a line-ending issue confusing the parser. I'm on Mac, so each line ends with a \n character.

Ok, I can see it now; at some point I indented with 4 spaces (the h1) and then tried to use 2 space indentation for the contents of the p element. I'm able to make progress now, so that's cool.

At the very least, I'd love to see a more useful error message to help me diagnose this, i.e., "expected 4 spaces, saw 2 spaces" or something.
