HTMLTextDocument() doesn't necessarily preserve the order of serialized dependencies #94
Description
If you run this code numerous times, notice that the ordering of dependencies aren't deterministic. By extension, ordering of "3rd party" HTML dependency Quarto docs with server: shiny also aren't deterministic.
from htmltools import HTMLDependency, HTMLTextDocument
html = '''
<html>
<head>
<script type="application/json" data-html-dependency="">
{"name": "ipywidget-libembed-amd", "version": "1.0.1", "source": {"package": "shinywidgets", "subdir": "static"}, "script": [{"src": "libembed-amd.js"}], "stylesheet": [], "meta": [], "all_files": false, "head": null}
</script>
<script type="application/json" data-html-dependency="">
{"name": "ipywidget-output-binding", "version": "0.3.2.9000", "source": {"package": "shinywidgets", "subdir": "static"}, "script": [{"src": "output.js"}], "stylesheet": [{"href": "shinywidgets.css", "rel": "stylesheet"}], "meta": [], "all_files": false, "head": null}
</script>
</head>
<body></body>
</html>
'''
doc = HTMLTextDocument(html, deps_replace_pattern='NA')
res = doc.render()
print(res["dependencies"])For example, here is output with the dependency ordering reversed:
[<HTMLDependency "ipywidget-output-binding-0.3.2.9000">, <HTMLDependency "ipywidget-libembed-amd-1.0.1">]The reason for this is because doing list(set(x)) on a list of strings does not necessarily preserve the original ordering:
