A script for export all drawio files to flat images (i.e. png).
I used this frequently for preparing images for my blogs.
It searches for all files with "*.drawio" extension and converts them one by one. It will also ignore files that have no updates since the last run.
This script assumed that you are on MacOS and you've installed the Draw.io application.
If you don't, install it from here https://github.com/jgraph/drawio-desktop.
This application comes with a command line tool as well.
To double check:
$ /Applications/draw.io.app/Contents/MacOS/draw.io --version
15.8.7
Check which python is being invoke from shell:
$ which python
If the output is managed by conda, e.g.:
/opt/miniconda3/bin/Users/yuchen/miniconda3/bin/python
Then it is all good. We can use that.
Also make sure the version of the Python is 3.9 and above.
$ python --version
Python 3.9.1
Check which python is being invoke from shell:
$ which python
/usr/bin/python
And check which version of the python it is linking to:
ls -l /usr/bin/python lrwxr-xr-x 1 root wheel 75 8 Nov 2019 /usr/bin/python -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
Here we can see it is pointing to a pretty old version of python 2.
Let's swap that out with the one managed by miniconda.
$ conda activate
$ which python
/Users/yuchen/miniconda3/bin/python
$ python --version
Python 3.7.11
$ ln -s /Users/yuchen/miniconda3/bin/python /usr/local/bin/python
And to double check:
$ conda deactivate
$ which python
/usr/local/bin/python
$ python --version
Python 3.9.1
$ python drawio_convert/drawio_convert.py
$ pip install .

This is optional only if it is not part of $PATH.

In any folder that contains drawio files.
