Breaking changes

• Removed: support for node 4
• Changed: from reduce(tokens[, compileDebug]) to reduce(tokens[, options])
• Changed: use strict mode and do not wrap code in with(locals) by default.

The old version (v4) compiled templates to sloppy JS mode and used the long-deprecated with() structure. The new (v5) version changes that, but allows one to opt-out.

We used with(locals) to allow one to write <%= x %> instead of <%= locals.x %>, but employing with() forced the lib to compile to sloppy mode since this construct isn't allowed in strict mode.

In this new version, we revisited that decision and prefered to drop with in favor of strict mode. To ease transition, you can opt-out and keep using the old behavior with the option strictMode: false. On the other hand, if don't want to keep writing locals. all the time, you can list which variables should be made available with the option vars: ['someVar', 'anotherOne']. See the examples below

/**
 * Old (v4)
 */

// Variables could be accessed directly, unless there were absent in the locals parameter
ejs.render('<%= a %>', {a: 2}) // '2'
ejs.render('<%= b %>', {a: 2}) // ReferenceError: b is not defined

// In sloppy mode, weird things happen, like leaking to global context
ejs.render('<% x = 17 %>') // ''
x // 17

/**
 * New (v5)
 */

// Direct access does not work out of the box
ejs.render('<%= a %>', {a: 2}) // ReferenceError: a is not defined

// You have to be explicit. Either use the locals object or list variables to be made available
ejs.render('<%= locals.a %>', {a: 2}) // '2'
ejs.render('<%= a %>', {a: 2}, {vars: ['a']}) // '2'
ejs.render('<%= b %>', {a: 2}, {vars: ['b']}) // ''

// Code is executed in strict mode
ejs.render('<% x = 17 %>') // ReferenceError: x is not defined

// If you REALLY want to use old behavior
ejs.render('<%= a %>', {a: 2}, {strictMode: false}) // '2'

Other changes

• Added: option strictMode (defaults to true)
• Added: option vars (defaults to [])

4.0.3

• Fixed: bug in minifier with spaces around some EJS tags

4.0.2

• Fixed: compiling custom elements inside custom elements with compileDebug set to false would crash on runtime. The fix on 4.0.1 did not covered the recursive case.
