Replace custom sitemap with datasette-sitemap

[simonw]

New plugin: https://github.com/simonw/datasette-sitemap

Can replace this:

datasette.io/plugins/seo.py

Lines 28 to 48 in d2c1545

	async def urls(datasette):
	paths = ["/", "/for", "/examples", "/plugins", "/tools", "/news"]
	db = datasette.get_database("content")
	for row in await db.execute("select _path from uses"):
	paths.append("/" + row["_path"].split(".")[0])
	for row in await db.execute("select name from plugins"):
	paths.append("/plugins/" + row["name"])
	for row in await db.execute("select name from tools"):
	paths.append("/tools/" + row["name"])
	return ("https://datasette.io{}".format(path) for path in paths)
	async def sitemap_xml(datasette):
	content = [
	'<?xml version="1.0" encoding="UTF-8"?>',
	'<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">',
	]
	for url in await urls(datasette):
	content.append("<url><loc>{}</loc></url>".format(url))
	content.append("</urlset>")
	return Response("\n".join(content), 200, content_type="application/xml")

Maybe use this as an excuse to solve the thing where datasette-block-robots and datasette-sitemap can intefere with each other since they both try to register /robots.txt.

Could do that by teaching datasette-block-robots to detect if datasette-sitemap is installed.
