Hikchr is a Haskell wrapper for Pikchr, a PIC-like markup language for diagrams.
Install by adding hikchr to your *.cabal file
and use the hikchr functions to convert Pikchr scripts to SVG:
import Hikchr
main :: IO ()
main = do
let pikchrScript = """
arrow right 200% "Markdown" "Source"
box rad 10px "Markdown" "Formatter" "(markdown.c)" fit
arrow right 200% "HTML+SVG" "Output"
arrow <-> down 70% from last box.s
box same "Pikchr" "Formatter" "(pikchr.c)" fit
"""
svgResult <- hikchrCustom
( HikchrConfig
{ svgClass = Just "example"
, darkMode = False
, width = Nothing
, height = Nothing
}
)
pikchrScript
-- Without configuration:
-- svgResult <- hikchr pikchrScript
case svgResult of
Left err -> putErrText err
Right svg -> writeFile "example.svg" svgwill generate following SVG:
Install by running cabal install hikchr or stack install hikchr
and use the hikchr command like this:
hikchr graph.pikchr > graph.svg
echo "box \"Hello\"" | hikchr > hello.svg
hikchr --dark-mode graph.pikchr > graph-dark.svg
hikchr --class graph graph.pikchr > graph.svg
hikchr example1.pikchr example2.pikchr \
| cat "<html><body>" - "</body></html>" \
> example.html
