This thread is excellent! I'm trying to get this working... Must be having some sort of basic setup issue or something. I'm just trying to use the basic "PAGEBREAK" replace option. import Text.Pandoc.JSON pgBrkXml :: String pgBrkXml = "" pgBrkBlock :: Block pgBrkBlock = RawBlock (Format "openxml") pgBrkXml insertPgBrks :: Block -> Block insertPgBrks (Para [Str "PAGEBREAK"]) = pgBrkBlock insertPgBrks blk = blk main = toJSONFilter insertPgBrks Getting all kinds of funky responses: As-MacBook-Air:poetry macair$ pandoc --filter /Users/macair/.pandoc/filter-pagebreak.hs test_ms.md -f markdown -t docx -s -o test_ms.docx /Users/macair/.pandoc/filter-pagebreak.hs: line 1: import: command not found /Users/macair/.pandoc/filter-pagebreak.hs: line 3: pgBrkXml: command not found /Users/macair/.pandoc/filter-pagebreak.hs: line 4: pgBrkXml: command not found /Users/macair/.pandoc/filter-pagebreak.hs: line 6: pgBrkBlock: command not found /Users/macair/.pandoc/filter-pagebreak.hs: line 7: syntax error near unexpected token `(' /Users/macair/.pandoc/filter-pagebreak.hs: line 7: `pgBrkBlock = RawBlock (Format "openxml")' pandoc: Error running filter /Users/macair/.pandoc/filter-pagebreak.hs Compiling the filter also seems to go wonky: As-MacBook-Air:.pandoc macair$ ghc --make filter-pagebreak.hs [1 of 1] Compiling Main ( filter-pagebreak.hs, filter-pagebreak.o ) filter-pagebreak.hs:8:1: Parse error: naked expression at top level Perhaps you intended to use TemplateHaskell I'm new to Haskell and pandoc. Assuming there's some simple, basic, no-brainer thing that I'm not doing? All best! -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.
