Changelog of @hackage/scholdoc-texmath 0.1

texmath (0.8)

  • Added OMML reader (Jesse Rosenthal).
  • Support latex \substack (#57).
  • Added EBoxed and implemented in readers and writers (#58).
  • Handle latex \genfrac. Use \genfrac for \brace, \brack, etc. when amsmath is available.
  • Improvements in handling of space characters.
  • Use ESpace rather than EText when a mathml mtext just contains a space.
  • Use \mspace when needed to get latex spaces with odd sizes, rather than finding the closest simple command.
  • Use Rational instead of Double in ESpaced, EScaled.
  • Shared: Export getSpaceWidth, getSpaceChars.
  • Shared: Export fixTree, isEmpty, empty (formerly in MathML reader).

texmath (0.7.0.2)

  • TeX reader: further improvements in error reporting. Instead of reporting line and column, a snippet is printed with a caret indicating the position of the error. Also fixed bad position information when control sequences are followed by a letter.

texmath (0.7.0.1)

  • TeX reader:

    • Improved error reporting.
    • Optimized parser.
    • Treat \ as ESpaced rather than ESymbol.
    • Internal improvements, including using the parsec3 interface instead of the older parsec2 compatibility interface.

  • Added tests for phantom.

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).
