a2dl 0.1.2

Generate draw.io icon libraries from AsciiDoc-based descriptions.

a2dl | (A)sciidoc(2D)rawio(L)ibrary

This script generates a draw.io library from AsciiDoc-based descriptions and updates diagrams that use icons from these libraries.

• It recursively searches for adoc files in a specified folder and scans for particular lines within these files.
• These lines are then integrated into HTML tooltips of draw.io icons.
• The icons are bundled into a draw.io / diagrams.net library.

I needed to visualize the relationship within previously written content. I wrote this script to extract relevant information from these articles into tooltips for draw.io icons. This allows me to concentrate on connecting the information and provide contextual information during a presentation.

Install

python3 -m pip install a2dl

Prepare Asciidoc files

To use this script, simply add the identifiers to any adoc file.

Set these variables at the top of the file

• :icon_image_rel_path: images/generated/3.png -> Path to an Icon Image PNG

• :icon_name: Icon3 -> Name for the Icon

• :read_more: #sec-icon3 -> Link for more info, to be appended to the tooltips end

These two lines form the start of a Tooltips content, while the first line will also work as a stop sign for the content extraction:

• == or === up to =====

• :variable_name: short_description -> choose any name for your variable, but do not include whitespace

Example Adoc

:toc:
:icon_image_rel_path: images/generated/3.png
:icon_name: Icon3
:read_more: #sec-icon3

[[sec-icon3]]
== Icon 3

image::{icon_image_rel_path}[The Icon 3s Alternative Text,160,160,float="right"]

=== Short Description
:variable_name: short_description

This is short Text to Describe the icon
A short abstract of the Topic

WARNING: Not Safe For Work


=== XML Attribute 1
:variable_name: xml_attribute_1

Some part of the text to add to the icons data 

Use

Use in CLI

python3 -m a2dl --library path/to/folder-to-scan path/to/library-file-to-write.xml
# OR
python3 -m a2dl --diagram path/to/folder-to-scan path/to/file-to-update
# OR
python3 -m a2dl --example path/to/folder-to-write

or

a2dl --library path/to/folder-to-scan path/to/library-file-to-write.xml
# OR
a2dl --diagram path/to/folder-to-scan path/to/file-to-update
# OR

Use in python script

A basic example.

import a2dl.a2dl

# Overwrite some constants
a2dl.a2dl.ICON_STYLE = "rounded=1;whiteSpace=wrap;html=1;"
a2dl.a2dl.IMAGE_STYLE = 'fillColor=none;rounded=1;shape=image;verticalLabelPosition=bottom;labelBackgroundColor=default;verticalAlign=top;aspect=fixed;imageAspect=0;image=data:image/{},{};'

a2dl.a2dl.logging.getLogger('a2dl').addHandler(a2dl.a2dl.logging.NullHandler())

# create icon
DI = a2dl.a2dl.Diagicon()
DI.from_adoc('./data/exampleDocument.adoc')
# write the icon to a Diagram file
DI.write_diagram('./data/test-generated-icon-from-exampleDocument.drawio')

# create a library
DL = a2dl.a2dl.Diaglibrary()
DL.from_folder('./data')
DL.write('./data/test-generated-library.xml')

#  update a diagram
DG = a2dl.a2dl.Diagdiagram()
DG.from_file('./data/exampleDiagramFromLibrary-old.drawio')
DG.update(libraries=[DL])
