🌟 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.
