diagrams-svg
diagrams-svg is a an SVG backend for diagrams. Diagrams is a powerful, flexible, declarative domain-specific language for creating vector graphics, using the Haskell programming language.
diagrams-svg is the default out-of-the box backend that comes with the diagrams framework, and supports most features defined in diagrams-lib.
Installation
cabal update && cabal install diagrams-svg
Usage
A simple example that uses diagrams-svg to draw a square.
import Diagrams.Prelude
import Diagrams.Backend.SVG.CmdLine
b1 :: Diagram B
b1 = square 20 # lw 0.002
main = mainWith (pad 1.1 b1)
Save this to file named Square.hs
and compile this program:
ghc --make Square.hs
This will generate an executable which, when run produces an SVG file. Run the
executable with the --help
option to find out more about how to call it.
$ ./Square --help
./Square
Usage: ./Square [-w|--width WIDTH] [-h|--height HEIGHT] [-o|--output OUTPUT] [--loop] [-s|--src ARG] [-i|--interval INTERVAL]
Command-line diagram generation.
Available options:
-?,--help Show this help text
-w,--width WIDTH Desired WIDTH of the output image
-h,--height HEIGHT Desired HEIGHT of the output image
-o,--output OUTPUT OUTPUT file
-l,--loop Run in a self-recompiling loop
-s,--src ARG Source file to watch
-i,--interval INTERVAL When running in a loop, check for changes every INTERVAL seconds.
-p,--pretty Pretty print the SVG output
You must pass an output file name with a .svg
extension to generate the SVG
file.
$ ./Square -o square.svg
The command above generates the SVG file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"

Bug fixes
-
Use
splitFills
to properly render certain diagrams with mixed lines and filled loops. Previously, in certain situations loops that should have been filled were not. (#43) -
Don’t emit last segment of a loop if it is linear.
See diagrams-cairo#38. This wasn’t actually causing any observable problems in the SVG backend output, but this seems a better/more robust way to do things in any case.
Closed issues:
- SVG backend doesn’t fill loops if they occur in the same subtree as a line #43

v1.0 (2013-11-25)
According to the PVP, these changes should require a major version bump. However, a major version bump would be quite annoying and I don’t expect these instance changes to affect anyone (the changes were made for internal reasons). Please yell if it does affect you.
Fixed bugs:
- SVG backend fills lines again #42
