#Using in command line

cargo install svgbob_cli

svgbob normally operates on stdin and stdout:

$ svgbob < examples/long.bob > long.svg

produces an SVG in long.svg similar to the one produced by the old main binary. svgbob also allows passing arguments instead:

$ svgbob examples/long.bob -o long.svg

And you can mix and match:

$ svgbob -o long.svg < examples/long.bob
$ svgbob examples/long.bob > long.svg

This is also documented in the output of svgbob --help:

$ svgbob --help
svgbob 0.1.2
SvgBobRus is an ascii to svg converter

USAGE:
    svgbob [OPTIONS] [input]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -o, --output <output>    where to write svg output [default: STDOUT]

ARGS:
    <input>    svgbob text file to parse [default: STDIN]
