🌟 11 Jan 2021, v4.0

Breaking

• Update section Unsure About in README.md, change the way this ambiguous expression parsed.
• extra.ellipsis now accept a boolean value, true, false.
• These expression are valid if allowed in options.extra.{ellipsis, blankTerms}:
  • (..., a)
  • (, a)
  • (a, ) is tuple depending on extra options.
• Intervals, should have 2 terms as math expression:
  • (..., a]: throw syntax error, parsed if extra.ellipsis is true
  • (..., a): is a tuple, parsed if extra.ellipsis is true
  • [2, 1, ]: is a matrix, parsed if extra.trailingComma is true
  • (1, 2,): is a tuple, parsed if extra.trailingComma is true
  • [, a]: is a matrix, parsed if extra.blankTerms is true
  • (, a): is a tuple, parsed if extra.blankTerms is true
• Remove option strict.

Add

• options.keepParen: if you want to parse parenthesis as nodes in the AST, { type: "parenthesis" }.
• options.extra.matrices
• options.builtInIDs
  • infinity, pi, phi: these have specific values or notions in maths.
  • phix is considered as automult of single-char ids, if options.singleCharName=true, otherwise it is node of type "id" with name "phix".
  • when strict the previous expression will be automult of single-char ids, equivalent to p*h*i*x.

1 Jan 2021, v3.0.0-alpha.0

Breaking

• Node of type "function", when its args is [{ type: "block", name: "()", ... }], function's args is assigned to parenthesis args. In other words, in this case it will be Array not { type: "block", ... }.
• Removing node type delimeter:
  • f(1,3,4) when parsed as function, it will have args with length 3.
  • (1,3,4) will be parsed with type = "tuple".

Added

• Built-in function sqrt
• Node of type "tuple": (1, 2, x, ...)

Update to version v2.2.1

31 Aug 2020, v2.2.1

Summary of changes:

• Add version property to the exported package, which is now "2.2.1"
• Add strict to options, see README.md
• Parse "member expression" such as "p.first_component" and "f(x).someThing.another()" wether or not options.singleCharName == true.
• When options.strict == false, "f()" is function regardless of options.functions.
• When options.strict == false, "f + a - sin" is parse with no "Function used as variable" error.
• Allow functions to be invoked by void parentheses such as "f()";
• A more intelligent way to handle
• Fix operators ^ and ! from the previous release to parse some expression like: "5^2x!" as "(5^2)(x!)".
