This is svgo, a small utility to create SVG objects.
This was inspired by `jpmens/jo `_.
.. contents:: Table of contents
Usage
=====
Basic usage
-----------
`-W` is a width of `svg` tag elements.
`-H` is a height of `svg` tag elements.
Default values are `200`.
.. code-block:: shell
$ svgo -W 400 -H 400 [ circle cx=200 cy=200 r=200 stroke=teal fill='#DDD' ]
Save file. (`-o`)
.. code-block:: shell
$ svgo -o out.svg [ circle cx=200 cy=200 r=200 stroke=teal fill='#DDD' ]
Nested elements.
.. code-block:: shell
$ svgo [ g [ circle cx=100 cy=100 r=80 stroke=teal fill="#DDD" ] [ circle cx=100 cy=100 r=80 stroke=teal fill="#DDD" ] ]
Use stdin fields. (`-i`)
.. code-block:: shell
$ seq 0 25 100 | svgo [ circle cx=100 cy=100 r='$1' ] -i
Animation GIF
-------------
You can generate animation GIF with ImageMagick (`convert`).
.. code-block:: shell
$ (seq 1 10 100; seq 100 -10 0) | svgo [ circle cx=100 cy=100 r='$1' ] -in -w 3 -o 'out_$NR.svg'
$ convert -density 1200 -resize 200x200 out_*.svg anim1.gif
|image-demo-anim1|
.. code-block:: shell
$ (seq 5 | awk '{print $1 * 40, 200}' | tee >(awk '{print $2, $1}')) | svgo [ rect x=0 y=0 width='$1' height='$2' ] -ino 'out_$NR.svg'
$ convert -resize 200x200 out*.svg anim2.gif
|image-demo-anim2|
.. code-block:: shell
$ yes 'echo $((RANDOM % 200)) $((RANDOM % 200))' | head | bash | svgo [ circle cx='$1' cy='$2' r='50' ] -ino 'out_$NR.svg'
$ convert -resize 200x200 out*.svg anim3.gif
|image-demo-anim3|
.. code-block:: shell
$ seq -f 'obase=16; ibase=10; %g' 0 15 | bc | awk '{print $1, "0", "0"}' | svgo [ circle cx=100 cy=100 fill='#$1$2$3' r=100 ] -ino 'out_$NR.svg'
$ convert -resize 200x200 out*.svg anim4.gif
|image-demo-anim4|
.. code-block:: shell
$ seq 0 16 360 | svgo [ g rotate='$1' [ rect x=0 y=0 width=100 height=100 ] ] -ino 'out_$NR.svg'
$ convert -resize 200x200 out*.svg anim5.gif
|image-demo-anim5|
.. code-block:: shell
$ seq 10 2 30 | svgo -i [ text x=0 y='$1' font-size='$1' TEXT=HelloWorld ] -no 'out_$NR.svg'
$ convert -resize 200x200 out*.svg anim6.gif
|image-demo-anim6|
.. code-block:: shell
$ r=100
j=0
for i in f47 d47 b47 947 747 547 347 147 047 027; do
j=$((j+1))
svgo [ circle cx=100 cy=100 r=$r fill="#$i" ] > out_$(printf %02d $j).svg
r=$((r-10))
done
$ convert out*.svg anim7.gif
|image-demo-anim7|
Installation
============
.. code-block:: shell
$ nimble install -Y svgo
or install binaries from `Releases `_.
Special variables
=================
Field variables ($1, $2, ... $NF)
---------------------------------
Records are read in stdin at a time, and stored in the field variables.
The record is split into fields which are stored in $1, $2, ..., $NF like `awk`
when activate `-i (--use-stdin)` flag.
.. code-block:: shell
$ seq 3 | svgo -i [ circle cx=100 cy=200 r='$1' ]
# equals
$ svgo [ circle cx=100 cy=200 r='1' ]
$ svgo [ circle cx=100 cy=200 r='2' ]
$ svgo [ circle cx=100 cy=200 r='3' ]
.. code-block:: shell
$ seq 3 | awk '{print $1, $1*10}' | svgo -i [ circle cx='$1' cy='$2' r='$1' ]
# equals
$ svgo [ circle cx='1' cy='10' r='1' ]
$ svgo [ circle cx='2' cy='20' r='2' ]
$ svgo [ circle cx='3' cy='30' r='3' ]
Current record number (NR)
