Changelog of @hackage/texmath 0.7

texmath (0.7)

• Changes in Exp type:

  • Removed EUp, EDown, EDownup, EUnary, EBinary.
  • Added EFraction (and FractionType), ESqrt, Eroot, EPhantom.
  • Added boolean "convertible" parameter to EUnder, EOver, EUnderover.
  • Changed parameter of EScaled from String to Double.
  • Changed parameter of ESpace from String to Double.
  • Removed EStretchy.
  • Added EStyled, corresponding to mstyle in mathml, and \mathrm, \mathcal, etc. in TeX (which can contain arbitrary math content, not just text).
  • Changed the type of EDelimited. The contents of an EDelimited are now either Right Exp or Left String (the latter case represents a fence in middle position, e.g. \mid| in LaTeX).

• Module reorganisation: the exposed interface has been completely changed, and modules for reading MathML and writing TeX math have been added:

  • All writers now reside in Text.TeXMath.Writers.

    • Text.TeXMath.MathML -> Text.TeXMath.Writers.MathML. toMathML and showExp are removed, writeMathML added.
    • Text.TeXMath.OMML -> Text.TeXMath.Writers.OMML. toOMML and showExp removed, writeOMML added.
    • Text.TeXMath.Pandoc -> Text.TeXMath.Writers.Pandoc. toPandoc removed, writePandoc added.
    • New module Text.TeXMath.Writers.TeX, exporting writeTeX, writeTeXWith, addLaTeXEnvironment (the latter giving control over which packages are assumed to be available).

  • All readers now reside in Text.TeXMath.Readers.

    • Text.TeXMath.MathMLParser -> Text.TeXMath.Readers.MathML, exporting readMathML.
    • Text.TeXMath.Readers.TeX nows exports readTeX rather than parseFormula.

  • New modules for unicode conversion: Text.TeXMath.Unicode.ToASCII, Text.TeXMath.Unicode.ToTeX, Text.TeXMath.Unicode.ToUnicode.

  • Two MathML specific modules: Text.TeXMath.Readers.MathML.EntityMap, Text.TeXMath.Readers.MathML.MMLDict.

  • In Text.TeXMath, all the XtoY functions have been removed in favour of rexporting raw reader and writer functions. The data type Exp is now also exported.

• Bug fixes and improvements.

  • TeX writer: Properly handle accents inside \text{}. Use real text environments for EText (\textrm, not \mathrm). Improved handling of scalers (\Big etc.). Use amsmath matrix environments when appropriate. Fixed \varepsilon.
  • MathML writer: Omit superfluous outer mrows. Add position information to fences.
  • OMML writer: Handle \phantom.
  • Pandoc writer: Use unicode characters to support Fraktur and other text styles.
  • TeX reader: Use EUnder/Over for \stackrel, \overset, \underset. Improved handling of primes. Fixed \notin. Avoid superfluous grouping of single elements. Improved handling of scalers (\Big etc.). Handle \choose, \brace, \brack, \bangle (#21).
  • Macros: Don't raise an error if applying a macro fails to resolve to a fixed point; instead, just return the original string.

• Rewrote test suite as a proper cabal test suite. Added --regenerate-tests and --round-trip options.

• Updated texmath online demo for bidirectional conversion.

• Removed cgi and test flags. Added executable flag to build texmath.

• Modified texmath so it works like a cgi script when run as texmath-cgi (through symlink or renaming). Removed dependency on the cgi package.

texmath (0.6.7)

• New Module: Text.TeXMath.Unidecode, a module for approximating unicode characters in ASCII.
• New Module: Text.TeXMath.Shared, a module for shared lookup tables between the various readers and writers
• New Module: Text.TeXMath.MathMLParser, exporting readMathML.
• New Module: Text.TeXMath.EntityMap, exporting getUnicode, a conversion table from MathML entities to unicode characters.
• New Module: Text.TeXMath.UnicodeToLaTeX, exporting getLaTeX, converting a string of unicode characters to a string of equivalent LaTeX commands.
• New Module: Text.TeXMath.LaTeX, replacing Text.TeXMath.Parser, exporting toTeXMath.
• New Module: Text.TeXMath.MMLDict, implements a lookup table from operators to their default values as defined by the MML dictionary, exporting getOperator.
• New Module: Text.TeXMath.Compat, maintaining compatibility with mtl < 2.2.1.
• Modified Text.TeXMath to export the primitive readers, as well as mathMLTo{Writer} for all writers
• Modified: Text.TeXMath.Types: added additional record types for Text.TeXMath.MMLDict and Text.TeXMath.UnicodeToLaTeX. New Exports: Operator(..), Record(..).
• Modified test suite: use cabal test, added significant number of tests.
• Added recognition of the LaTeX command \phantom

texmath (0.6.6.3)

• Use combining tilde accent for \tilde. Closes pandoc #1324.

texmath (0.6.6.2)

• Allow \left to be used with ), ], etc. Ditto with \right. Previously only (, [, etc. were allowed with \left. Closes pandoc #1319.

texmath (0.6.6.1)

• Support \multline (previously it was mispelled "multiline")
• Changed data-files to extra-source-files.

texmath (0.6.6)

• Insert braces around macro expansions to prevent breakage (#7).
• Support \operatorname and \DeclareMathOperator (rekka) (#17).
• Support \providecommand (#15).
• Fixed spacing bugs in pandoc rendering (#24).
• Ignore \hline at end of array row instead of failing (#19).
