Changelog of @hackage/texmath 0.8.6.6

texmath (0.8.6.6)

• Allow pandoc-types 1.17.*.

texmath (0.8.6.5)

• Fixed transposition of sub/super on operators (jgm/pandoc#3040).

texmath (0.8.6.4)

• Support 'equation' environment, without the numbering of course.

texmath (0.8.6.3)

• Use POST instead of GET for texmath-cgi.

texmath (0.8.6.2)

• Fixed array alignment issues (jgm/pandoc#2864, jgm/pandoc#2310).
• Use 1 and 0 for _Hide attributes, rather than on and off. Officially it seems that either 1/0 or true/false are wanted.
• Fixed EUnderOver for omml output. Previously both the under and the over part were being placed under (jgm/pandoc#2775).

texmath (0.8.6.1)

• OMML writer: Fixed rendering of roots, so that the degree appears in the right place.
• OMML writer: Don't include empty rPr elements.

texmath (0.8.6)

• TeX reader: Support hundreds more math symbols (all of those defined in Text.TeXMath.Unicode.ToTeX), including \nwarrow, \swarrow, \nearrow, \searrow (#90).

texmath (0.8.5.1)

• OMML writer: Fixed order of elements in nary formulas to conform to OMML spec (#88, Niko Weh). <e> must follow the <sup> and <sub> parts of <nary>. This fixes rendering issues in LibreOffice (though Word copes with the incorrect order).
• Added Paths_texmath to Other-Modules for texmath executable.

texmath (0.8.5)

• TeX parser: Support limited styling inside \DeclareMathOperator (#85).
• TeX reader: Correctly parse \mbox. Its argument is text mode.
• Updated mathml tests to use mo for operators.
• TeX reader: support mathopen, mathclose, mathpunct.
• MathML writer: render EMathOperator as mo, not mi (#86).
• MathML: handle leading space in EText (#87).
• Take --version in executable from cabal metadata.
• Added Paths_texmath to other-modules.

texmath (0.8.4.2)

• Fixed overbrace, underbrace (#82). Previously we were using the wrong character: U+FE37 instead of U+23DE. This didn't work in Word.
• Support \mathop, \mathrel, \mathbin, \mathord
• MathML - render Symbol Ord as mi, not mo (#83).
• Handle align environments with > 2 cells per row (#84).

texmath (0.8.4.1)

• Added stack install instructions.
• Fixed bold-italic in OMML (#76). Previously \mathbfit didn't work properly in OMML output.
• Ignore \nonumber (#79).
• Allow styling in \operatorname e.g. \operatorname{\mathcal{L}} (#80).
• Fixed bug in supHide and subHide for OMML. This led to little empty boxes being displayed in integrals with subscripts but no superscripts. See jgm/pandoc#2571.
• Implemented \mod as a math operator (#81). This doesn't capture all the spacing subtleties of the amsmath version, but should be good enough for most purposes.
• Allow pandoc-types < 1.17.

texmath (0.8.4)

• Improved symbol spacing in Pandoc output (jgm/pandoc#2261). This change avoids putting space around binary symbols that come at the beginning or end of a group, or appear on their own. It also avoids spacing on a binary symbol that follows a Bin, Op, Rel, Open, or Punct atom, in accord with TeXBook Appendix G. We could go farther towards exactly matching the TeXBook rules, but this simple change goes some of the way.
• Added stack.yaml.

texmath (0.8.3)

• Parse uppercase Greek letters as EIdentifier, not ESymbol Op. This fixes handling of things like $Lambda^1$, particularly in omml.

texmath (0.8.2.2)

• Handle . after number with no following digits.

texmath (0.8.2.1)

• Handle bare hyphen in \text{...}. Closes jgm/pandoc#2274.
• Support \ltimes and \rtimes in the TeX reader (Arata Mizuki).
• Slightly more efficient number parser.

texmath (0.8.2)

• Better handling of decimal points. Decimal points are now parsed as parts of numbers, not as separate symbols. E.g. in MathML they now appear in <mn> elements. Closes #74.

texmath (0.8.1)

• OMML: Don't force everything into Roman font by default. This change ensures that variables will be italic by default in Word. See jgm/pandoc#2075.

texmath (0.8.0.2)

• Fixed typo in defaultEnv to include amssymb (#68).
• Moved some lookup tables to C, and disabled aggressive profiling defaults, to avoid excessive memory usage in compiling with clang (#70).
• Support \newcommand* in parseMacroDefinition (jgm/pandoc#2005).
• Fixed order bug for over/under in OMML reader (#66).
• Support \boldsymbol (#67).

texmath (0.8.0.1)

• Added network-uri flag. This addresses the split of network and network-uri packages.
• OMML reader: change default accent (Jesse Rosenthal). The default had previously been set as accute (possibly as a placeholder). It appears to be circumflex/hat instead.

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.

• 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
