The diagrams-svg package

[Tags: bsd3, library]

This package provides a modular backend for rendering diagrams created with the diagrams EDSL to SVG files. It uses blaze-svg to be a fast, native Haskell backend, making it suitable for use on any platform.

The package provides the following modules:

Readme for diagrams-svg-1.0.1

Build Status

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 = 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.

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"
    "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
