From 0cb7362f62410f58e2356381bbf2c1fe85abe2a5 Mon Sep 17 00:00:00 2001 From: John MacFarlane Date: Thu, 9 Aug 2012 20:19:06 -0700 Subject: Removed `--strict`, added extensions to writer/reader names. * The `--strict` option has been removed. * Instead of using `--strict`, one can now use `strict` instead of `markdown` as an input or output format name. * The `--enable` and `--disable` optinos have been removed. * It is now possible to enable or disable specific extensions by appending them (with '+' or '-') to the writer or reader name. For example `pandoc -f markdown-footnotes+hard_line_breaks`. * The lhs extensions are now implemented this way, too; you can use either `+lhs` or `+literate_haskell`. --- src/Text/Pandoc.hs | 19 ++++++++++++++----- src/Text/Pandoc/Shared.hs | 5 +++-- src/Text/Pandoc/Templates.hs | 17 +++++++++-------- 3 files changed, 26 insertions(+), 15 deletions(-) (limited to 'src/Text') diff --git a/src/Text/Pandoc.hs b/src/Text/Pandoc.hs index 06bfd128f..61e461b35 100644 --- a/src/Text/Pandoc.hs +++ b/src/Text/Pandoc.hs @@ -139,11 +139,13 @@ import Text.Pandoc.Templates import Text.Pandoc.Options import Text.Pandoc.Shared (safeRead) import Data.ByteString.Lazy (ByteString) +import Data.List (intercalate) import Data.Version (showVersion) import Text.JSON.Generic import Data.Set (Set) import qualified Data.Set as Set import Text.Parsec +import Text.Parsec.Error import Paths_pandoc (version) -- | Version number of pandoc library. @@ -160,10 +162,12 @@ parseFormatSpec = parse formatSpec "" formatName = many1 $ noneOf "-+" extMod = do polarity <- oneOf "-+" - name <- many1 $ noneOf "-+" - ext <- case safeRead name of + name <- many $ noneOf "-+" + ext <- case safeRead ("Ext_" ++ name) of Just n -> return n - Nothing -> unexpected $ "Unknown extension: " ++ name + Nothing + | name == "lhs" -> return Ext_literate_haskell + | otherwise -> fail $ "Unknown extension: " ++ name return $ case polarity of '-' -> Set.delete ext _ -> Set.insert ext @@ -172,6 +176,8 @@ parseFormatSpec = parse formatSpec "" readers :: [(String, ReaderOptions -> String -> Pandoc)] readers = [("native" , \_ -> readNative) ,("json" , \_ -> decodeJSON) + ,("strict" , \o -> readMarkdown + o{ readerExtensions = strictExtensions } ) ,("markdown" , readMarkdown) ,("rst" , readRST) ,("docbook" , readDocBook) @@ -215,6 +221,8 @@ writers = [ ,("texinfo" , PureStringWriter writeTexinfo) ,("man" , PureStringWriter writeMan) ,("markdown" , PureStringWriter writeMarkdown) + ,("strict" , PureStringWriter $ \o -> + writeMarkdown o{ writerExtensions = strictExtensions } ) ,("plain" , PureStringWriter writePlain) ,("rst" , PureStringWriter writeRST) ,("mediawiki" , PureStringWriter writeMediaWiki) @@ -224,10 +232,11 @@ writers = [ ,("asciidoc" , PureStringWriter writeAsciiDoc) ] +-- | Retrieve reader based on formatSpec (format+extensions). getReader :: String -> Either String (ReaderOptions -> String -> Pandoc) getReader s = case parseFormatSpec s of - Left e -> Left $ show e + Left e -> Left $ intercalate "\n" $ [m | Message m <- errorMessages e] Right (readerName, setExts) -> case lookup readerName readers of Nothing -> Left $ "Unknown reader: " ++ readerName @@ -239,7 +248,7 @@ getReader s = getWriter :: String -> Either String Writer getWriter s = case parseFormatSpec s of - Left e -> Left $ show e + Left e -> Left $ intercalate "\n" $ [m | Message m <- errorMessages e] Right (writerName, setExts) -> case lookup writerName writers of Nothing -> Left $ "Unknown writer: " ++ writerName diff --git a/src/Text/Pandoc/Shared.hs b/src/Text/Pandoc/Shared.hs index 9f615867c..ad28b7c23 100644 --- a/src/Text/Pandoc/Shared.hs +++ b/src/Text/Pandoc/Shared.hs @@ -498,5 +498,6 @@ warn msg = do safeRead :: (Monad m, Read a) => String -> m a safeRead s = case reads s of - (d,[]):_ -> return d - _ -> fail $ "Could not read `" ++ s ++ "'" + (d,x):_ + | all isSpace x -> return d + _ -> fail $ "Could not read `" ++ s ++ "'" diff --git a/src/Text/Pandoc/Templates.hs b/src/Text/Pandoc/Templates.hs index 061be29aa..899f6510a 100644 --- a/src/Text/Pandoc/Templates.hs +++ b/src/Text/Pandoc/Templates.hs @@ -86,15 +86,16 @@ import qualified Control.Exception.Extensible as E (try, IOException) getDefaultTemplate :: (Maybe FilePath) -- ^ User data directory to search first -> String -- ^ Name of writer -> IO (Either E.IOException String) -getDefaultTemplate _ "native" = return $ Right "" -getDefaultTemplate _ "json" = return $ Right "" -getDefaultTemplate _ "docx" = return $ Right "" -getDefaultTemplate user "odt" = getDefaultTemplate user "opendocument" -getDefaultTemplate user "epub" = getDefaultTemplate user "html" getDefaultTemplate user writer = do - let format = takeWhile (/='+') writer -- strip off "+lhs" if present - let fname = "templates" "default" <.> format - E.try $ readDataFile user fname + let format = takeWhile (`notElem` "+-") writer -- strip off extensions + case format of + "native" -> return $ Right "" + "json" -> return $ Right "" + "docx" -> return $ Right "" + "odt" -> getDefaultTemplate user "opendocument" + "epub" -> return $ Right "" + _ -> let fname = "templates" "default" <.> format + in E.try $ readDataFile user fname data TemplateState = TemplateState Int [(String,String)] -- cgit v1.2.3
