Continuing with the script from How to efficiently query dependencies for all changes?, I’ve been trying to find a set of parameters that works to be able to see a large graph.
It seems to work on Graphviz Visual Editor but I don’t understand how to view the output SVG in a way that I can read the labels. I’m using SVG so that there are links to the Nest for each.
Here is a screenshot of one export of a part of Pijul dependencies (can’t put SVG here):

I’ve kind of given up on the graph.
Instead, I modified the script to generate HTML, which could be a log
option like --output-format html
.
This shows both directions of the dependencies.
(this script inherited the function parentheses, which could probably be removed)
Direct the output to a .htm file.
Edit: I added code to output list of files for each change.
Edit: I convert <
to <
in the message and description.
#!/bin/bash
