Convert SVG images into:

• OmniGraffle Stencil
• diagrams.net (formerly draw.io) library

Features:

• parametrize connection points (magnets)
• filter images by name
• format icon names

See diagrams-aws-icons with generated AWS Architecture Icons library for diagrams.net.

Idea based on script from AWS-OmniGraffle-Stencils

Requires Python 3.8+ and Poetry.

Install dependencies in virtual env:

poetry install

Run:

poetry run icons-asset-generator \
    --path ./icons-directory [<common-args>] \
    <target-application> [<application-args>]

where <target-application> is one of:

• diagrams.net
• omnigraffle

• --path - input files directory path
• --output - output directory path (default: ./library)
• --filename-includes - strings to filter image file name by, taking only those which contains them all; accepts multiple arguments
• --filename-excludes - strings to filter image file name by, taking only those which do not contain any of them; accepts multiple arguments
• --image-name-remove - strings to be removed from image file name (default: . - _); accepts multiple arguments
• --library-name-remove - strings to be removed from library file name (default: . - _); accepts multiple arguments
• --no-vertex-magnets - don't create connection points on vertices (corners)
• --side-magnets - number of connection points for each side (default: 5)
• --labels - add label with name to the images
• --help - display help

All SVG files from the given path will be added to the output asset, recursively.

If you provide arguments accepting multiple arguments, put the --path argument last so the parser knows where arguments stop and parses <target-application> parameter correctly.

• --size - resize images to target size; accepts argument in format TYPE=NUMBER where TYPE is one of width, height, longest

• --text-output - write OmniGraffle data file as text instead of binary

If SVG files are grouped into directories, each root-level directory will become a separate group in the output Stencil.

For example, this structure:

svg/
├── Group 1/
│   ├── icon1.svg
│   ├── icon2.svg
│   ├── icon3.svg
└── Group 2/
    ├── icon4.svg
    └── Subgroup
        └── icon5.svg

would produce a Stencil with Group 1 with 3 icons and Group 2 with 2 icons.

To generate icons from AWS Architecture Icons download SVG zip file (example: Asset-Package_04302022) and unpack it.

Run:

poetry run icons-asset-generator \
    --filename-includes _48 \
    --filename-excludes Dark \
    --image-name-remove Light Arch_ Res_ _48 . - _  \
    --library-name-remove  . - _ \
    --path "./Asset-Package_04302022" \
    diagrams.net

Open diagrams.net and load created asset from the ./library directory.
