mathup v.next Release Notes

Language Changes

  • The following floor and ceil operators are now considered fences.
    • |__ ⇒ ⌊
    • __| ⇒ ⌋
    • |~ ⇒ ⌈
    • ~| ⇒ ⌉
  • Added the following fences:
    • << ⇒ ⟨
    • >> ⇒ ⟩

mathup v1.0.0-alpha.2 Release Notes

Language Changes

  • Meaningful identifiers and operators cannot immedietly follow—or be followed by—an alphabetic character. E.g. asinb will not combine the sin into a single identifier. Surround the identifier with spaces to get the desired result. E.g. a sin b, or—better yet—use invisible (zero width) operators (U+2061–U+2064; a&*sin&$b; see below).
  • Infixes (e.g. /, ^, or _) now follow a consistent grammar. It will operate on the previous/next literal if it immediately presides/follows (e.g. no space between), otherwise it will operate on the previous/next expression (i.e. terms grouped together by surrounding space/parens/other infixes).
  • Font commands now work on the following expression, as opposed to just following token elements. E.g. now its possible to do bf [a; b] to make all the terms of the matrix bold-face.
  • Bevelled fractions (a./b) have been removed. They are deprecated in MathML and might be removed from browsers soon. Use a//b instead for a fraction slash operator.
  • Removed nested bracket matrix notation: [(a, b), (c, d)]. Use column seperators or newlines for writing matrices: [a, b; c, d].
  • pipe fences and matrices (|a,b;c,d| and ||a,b;c,d||) now require inner parenthesis (|(a,b;c,d)| and ||(a,b;c,d)|| respectively).
  • Unicode numbers are now strictly (with one expection) in the Nd, Nl, and No unicode categories. The only exceptions are the dozenal U+218A ↊ TURNED DIGIT TWO and U+218B ↋ TURNED DIGIT THREE. This omits CJK numerals (like 二, 四, or 万) that were previously mapped to number literals. Prepend then with octothorpe (#四十二) if you want the old behavior.
  • Backslash operators in brackets \(foo), \[bar] have been removed. Instead they follow the same syntax as octothorpe numbers. Write \int for alphanumeric operators, or \`foo bar` if they contain symbols. If you need to use a backtick as an operator then the fencing follows the same syntax as markdown. \`` ` ``. The same goes for octothorpe numbers #`forty two`, identifiers `foo bar`, and text "" "in quotes" "".
  • Roots are now notated as taking two args (just like binom). write root(a, b) or root a b. Unlike previous versions root(a)(b) will now include the brackets around a and b.

Output Changes

  • Fenced groups will no long render in the deprecated <mfenced> element. Instead it renders in the visually equivalent <mrow>s with <mo>s as fences and seperators.
  • lim and mod now map to opperators and render in an <mo> element.

Additions

  • Added .toString() and .toDOM() methods to the returned object.
  • Added obrace and ubrace to accents.
  • Added invisible operators &+, &*, &,, and &$ for implied addition, multiplication, seperation and function application respectively.

Breaking Changes

  • Removed the following opitons from the main function—they might be reimplented if demand is there:
    • annotate
    • bare
    • standalone
  • Calling main function with a single option parameter no longer returns another main function with those options applied. If you want to curry the main function, use an arrow function or a library: 
    const curried = input => mathup(input, { display: "block" })
  • Main function no longer returns string by default. Use the .toString() method of the returned object instead.

Ascii2MathML v0.7.1 Release Notes

Fixes

  • binom function can now handle empty terms #32

Contributors

Ascii2MathML v0.7.0 Release Notes

Additions

  • Added binom(a, b) for the binomial coefficient.

Braking Changes

  • A two row column vector, denoted with (a; b) will no longer turn into a binomial coefficient. It will stay as a column vector. Use binom(a, b) if you want the old behavior.

Changes

  • Semicolon- and newline seperated matrices [a, b; c, d] now take precedence over parenthesis delimited matrices [(a, b), (c, d)] in case of ambiguity.

Ascii2MathML v0.6.2 Release Notes

Fixes

  • Fixed binary not working on native node. (#25)

Contributors

Ascii2MathML v0.6.1 Release Notes

Fixes

  • Updated dependencies passing npm audit. (#24)

Changes

  • Comma/semicolon matrices to take precedence over bracket delimited matrices. (#19)

Contributors

Ascii2MathML v0.6.0 Release Notes

Braking Changes

  • Dropped support for io.js and node versions 0.10.x through 7.x. Now support is only from node version 8.x.
  • Stopped transpiling down to ES5. This includes the distributed scripts and the npm published package. This means that if you want to support old browsers or runtimes you must transpile the scripts your self, using e.g. Babel.
  • Dropped Babel as a runtime dependency. This means that if you are going to support old browsers or node environments you must provide your own polyfills for ES-2015+ methods.

Additions

  • Added new operators:
    • |>< ⇒ ‘⋉’
    • ><| ⇒ ‘⋊’
    • |><| ⇒ ‘⋈’
    • -<= ⇒ ‘⪯’
    • >-= ⇒ ‘⪰’
    • ~= ⇒ ‘≅’
    • >-> ⇒ ‘↣’
    • ->> ⇒ ‘↠’
    • >->> ⇒ ‘⤖’
  • Added complex groupings:
    • abs(a + b) ⇒ |a + b|
    • floor(a + b) ⇒ ⌊a + b⌋
    • ceil(a + b) ⇒ ⌈a + b⌉
    • norm(a + b) ⇒ ∥a + b∥
  • Added tilde (~) as a new accent.
  • Added cancel as a new accent that diagonally strikes through the following expression.

Changes

  • Whitespace between font modifiers and expressions is now allowed. e.g. it"foo" and it "foo" are now equivalent.
  • Expressions ending in Fraction, root, sqrt, sub, sup, under or overscript opperations without opperands, will opperate on the empty <mrow> instead of throwing an irrelevant expression. For example sqrt yields an empty squared root.
  • Unclosed fences (a, b, will now longer throw exeptions, Instead the fence will be implicitly closed with the empty string.

Contributors

Ascii2MathML v0.5.0 Release Notes

New features

  • Passing in the dir: "rtl" option will add the attribute to the root math element, for right-to-left directionality.

Changes

  • The == operator now maps to ≡.

Ascii2MathML v0.4.0 Release Notes

New features

  • Allowing arbitrary numerals using the #`...` syntax.
  • Ascii2MathML will now recognize most UNICODE numerals. The numeral codeblocks were borrowed from xregexps (unicode-plugin)[http://xregexp.com/plugins/#unicode], but extended to include the duodecimals and Chinese/Japanese numerals.

Changes

  • Supplying a minified version through the distributied code.

Ascii2MathML v0.3.0 Release Notes

New features

  • A trailing rowbrake in matrices are allowed. A trailing rowbrake in a fence will force a row-matrix.
  • Newlines functions as rowbrakes for matrices.

Changes

  • Compiling the code to ECMA-5 with Babeljs pre-publish. That means it will run on node 0.10.x environments.

Ascii2MathML v0.2.0 Release Notes

New features

  • Added parsing options for decimal mark, column separators and row separators.
  • Calling ascii2mathml with only an object will return another ascii2mathml function with the objects values as the new defaults.
