Version constraint

[laurentvd]

Question; is there a reason why this package has a <3.0 handlebars dependency? I mean, 3.0 and 4.0 are out yet. Is there a known incompatibility?

Hi @laurentvd, no incompatibility that I'm aware of. That constraint was set before version 3 came out. I'd be happy to merge a PR that loosens the contraint if the tests all pass 👍

Unfortunately the tests fail 👎 with a <5 constraint. I dug a little deeper and it seems the AST signature that is returned from Handlebars.parse is different in newer versions. I'm sorry to say I'm not familiair with handlebars so it's pretty hard for me to fix the issue. If anyone wants to take a stab at this, here's the different formats:

Pre 3.0 (the statements array is the relevant part here)

ProgramNode {
    firstLine: 1,
    firstColumn: 0,
    lastColumn: 26,
    lastLine: 1,
    type: 'program',
    statements: [],
    strip: {}
}

4.0 (and maybe also 3.0)

{
    type: 'Program',
    body: [],
    strip: {},
    loc: {
        source: undefined,
        start: {},
        end: {}
    }
}

I'm not sure what the equivalent of statements would be in the new format.
