From f53fb554fe0acf88d7c697236bbd1373e78f3d83 Mon Sep 17 00:00:00 2001 From: fiddlosopher Date: Wed, 13 Aug 2008 03:02:42 +0000 Subject: Support for display math; changed ASCIIMathML -> LaTeXMathML: Resolves Issue #47. + Added a DisplayMath/InlineMath selector to Math inlines. + Markdown parser yields DisplayMath for $$...$$. + LaTeX parser yields DisplayMath when appropriate. Removed mathBlock parsers, since the same effect is achieved by the math inline parsers, now that they handle display math. + Writers handle DisplayMath as appropriate for the format. + Changed -m option to use LaTeXMathML rather than ASCIIMathML. LaTeXMathML is closer to LaTeX in its display of math, and supports many non-math LaTeX environments. + Modified HTML writer to print raw TeX when LaTeXMathML is being used instead of suppressing it. + Removed ASCIIMathML files from data/ and added LaTeXMathML. + Replaced ASCIIMathML with LaTeXMathML in source files. + Modified README and pandoc man page source. + Modified web page. + Added --latexmathml option (kept --asciimathml as a synonym for backwards compatibility) + Modified tests accordingly; added new tests for display math. git-svn-id: https://pandoc.googlecode.com/svn/trunk@1409 788f1e2b-df1e-0410-8736-df70ead52e1b --- Main.hs | 6 +- README | 20 +- Text/Pandoc/ASCIIMathML.hs | 14 - Text/Pandoc/Definition.hs | 5 +- Text/Pandoc/LaTeXMathML.hs | 14 + Text/Pandoc/Readers/LaTeX.hs | 61 +- Text/Pandoc/Readers/Markdown.hs | 11 +- Text/Pandoc/Shared.hs | 6 +- Text/Pandoc/Writers/ConTeXt.hs | 3 +- Text/Pandoc/Writers/Docbook.hs | 2 +- Text/Pandoc/Writers/HTML.hs | 24 +- Text/Pandoc/Writers/LaTeX.hs | 3 +- Text/Pandoc/Writers/Man.hs | 5 +- Text/Pandoc/Writers/Markdown.hs | 3 +- Text/Pandoc/Writers/MediaWiki.hs | 2 +- Text/Pandoc/Writers/OpenDocument.hs | 2 +- Text/Pandoc/Writers/RST.hs | 6 +- Text/Pandoc/Writers/RTF.hs | 2 +- Text/Pandoc/Writers/Texinfo.hs | 5 +- data/ASCIIMathML.js | 3363 ----------------------------------- data/ASCIIMathML.js.comment | 2 - data/ASCIIMathML.js.packed | 374 ---- data/LaTeXMathML.js.comment | 16 + data/LaTeXMathML.js.packed | 191 ++ man/man1/pandoc.1.md | 6 +- pandoc.cabal | 8 +- tests/latex-reader.native | 14 +- tests/s5.fancy.html | 480 ++--- tests/s5.native | 2 +- tests/testsuite.native | 15 +- tests/testsuite.txt | 4 +- tests/writer.context | 5 +- tests/writer.docbook | 5 +- tests/writer.html | 4 +- tests/writer.latex | 5 +- tests/writer.man | 4 +- tests/writer.markdown | 4 +- tests/writer.mediawiki | 3 +- tests/writer.native | 15 +- tests/writer.opendocument | 5 +- tests/writer.rst | 4 +- tests/writer.rtf | 3 +- tests/writer.texinfo | 6 +- web/index.txt.in | 1 - 44 files changed, 514 insertions(+), 4219 deletions(-) delete mode 100644 Text/Pandoc/ASCIIMathML.hs create mode 100644 Text/Pandoc/LaTeXMathML.hs delete mode 100644 data/ASCIIMathML.js delete mode 100644 data/ASCIIMathML.js.comment delete mode 100644 data/ASCIIMathML.js.packed create mode 100644 data/LaTeXMathML.js.comment create mode 100644 data/LaTeXMathML.js.packed diff --git a/Main.hs b/Main.hs index 5fbffed8e..67ab68b99 100644 --- a/Main.hs +++ b/Main.hs @@ -249,12 +249,12 @@ options = (\opt -> return opt { optSmart = True })) "" -- "Use smart quotes, dashes, and ellipses" - , Option "m" ["asciimathml"] + , Option "m" ["latexmathml", "asciimathml"] (OptArg (\arg opt -> return opt { optHTMLMathMethod = - ASCIIMathML arg }) + LaTeXMathML arg }) "URL") - "" -- "Use ASCIIMathML script in html output" + "" -- "Use LaTeXMathML script in html output" , Option "" ["mimetex"] (OptArg diff --git a/README b/README index 9e588a4d7..73cb92f3a 100644 --- a/README +++ b/README @@ -310,27 +310,27 @@ For further documentation, see the `pandoc(1)` man page. `markdown`.
