1.2.1

Bugfix compile(tag, { csp: true }) should now work correctly.

1.2.0

Add four options to the second arg of the compile method :

  • compile(tag, {filters: { upper: (input) => input.toUpperCase()}}) which adds filters to a specific instance (those filters are not shared between instances).

  • compile(tag, {cache: {}}) to set a "non global" cache.

  • compile(tag, { csp: true }) to use the interpreter (avoid use of "new Function()" which is for example not allowed in Vercel).

  • compile(tag, {literals: { true: true, false: false, null: null, undefined: undefined } }) which allows to customize literals (such as null, true, false, undefined)

1.1.10

Update typescript typings for "Parser"

1.1.9

Update typescript typings (add .assign method)

1.1.8

Update typescript typings (add filters).

1.1.7

Add typescript typings (for compile, Parser and Lexer).

1.1.6

Published by mistake (same as 1.1.7), but without dependency changes

1.1.5

Add specific error when a filter is not defined.

1.1.4

Bugfix : When using an assignment expression, such as b = a, the value will always be set in the scope, not in the locals.

With this code :

const scope = { a: 10 };
const locals = { b: 5 };
compile("b=a")(scope, locals);

The scope value will be { a: 10, b: 10 } after the evaluation.

In previous versions, the value would be assigned to the locals, meaning locals would be { b: 10 }

1.1.3

Bugfix : Make module ES5 compatible (to work in IE10 for example), by using var instead of const

1.1.2

  • Disallow access to prototype chain (CVE-2021-21277)

1.1.1

Previous version was published with ES6 feature, now the published JS uses ES5 only

1.1.0

  • Add support for special characters by using the following :
function validChars(ch) {
  return (
    (ch >= "a" && ch <= "z") ||
    (ch >= "A" && ch <= "Z") ||
    ch === "_" ||
    ch === "$" ||
    "ÀÈÌÒÙàèìòùÁÉÍÓÚáéíóúÂÊÎÔÛâêîôûÃÑÕãñõÄËÏÖÜŸäëïöüÿß".indexOf(ch) !== -1
  );
}
evaluate = compile("être_embarassé", {
  isIdentifierStart: validChars,
  isIdentifierContinue: validChars,
});

evaluate({ être_embarassé: "Ping" });

1.0.1

  • Disallow access to prototype chain (CVE-2020-5219)

1.0.0

  • Add support for this keyword to write :
evaluate = compile("this + 2")(2); // which gives 4
