A PDF fillable textfield which flows with text on a page using Reportlab.

	from reportlab.platypus import SimpleDocTemplate, Flowable, Paragraph
	from reportlab.lib.styles import getSampleStyleSheet


	style = getSampleStyleSheet()['BodyText']

waylan / service_year.py

Created February 22, 2021 21:10

A Python object which represents a year that runs from Sept to Aug.

	import datetime

	class ServiceYear():
	'''
	A year which runs from Sept to Aug.

	Accepts a year in any format which can be converted to an integer.

	>>> year = ServiceYear(2021)

waylan / pd_service_year.py

Last active February 22, 2021 19:14

A couple functions which use Pandas to work with a year which runs from Sept to Aug. Each function only wraps a single line of Pandas calls, so their value is limited. But, remembering how to accomplish the things they do is valuable.

	import pandas

	def get_service_year(date):
	'''
	Return service year for given date.

	The service year runs from Sept to Aug and Sept-Dec are in the service year of
	the following calendar year. In other words, the date 2020-09 will return 2021.

	Accepts date as an ISO formatted string (for example YYYY-MM), a datetime.date

waylan / example.yml

Last active November 12, 2020 02:44

A custom YAML tag for referencing environment variables in YAML files. The content of the env var will be resolved to one of YAML's implicit types (bool, float, int, timestamp, null, value). The content of the env var is always assumed to be a Scalar node, so sequence and mappings are ignored and simply passed through as a string.

	foo: !ENV FOO
	bar: !ENV [BAR]
	baz: !ENV [BAZ, ~]
	fbb: !ENV [FOO, BAR, BAZ, ~]

Proof of concept for yaml inherit tag. Unfortunately, defining the tag is ugly. This was based on the code in [this comment](https://gist.github.com/joshbode/569627ced3076931b02f#gistcomment-2309157).

	# Unforunately, the tag can't be a standalone item by itelf.
	# After all, the following document is invalid:
	# foo
	# a: bar
	# Therefore the tag needs to fit in with the structure of the document.
	# I have used a null key and then discard it in the loader
	# so that it is not in the final output.

	null: !inherit parent.yml

waylan / rawhtmltokens.py

Created September 16, 2020 18:41

Some test tools I used when refactoring Python-Markdown's HTML parser. Preserved here for future reference.

	import markdown

	src = """
	<div><p markdown="1">Hello _World!_</p></div>
	"""
	md = markdown.Markdown(extensions=['md_in_html'])
	print('Doc: ', '\n'.join(md.preprocessors['html_block'].run(src.split('\n'))))
	print('Stash: ', md.htmlStash.rawHtmlBlocks)
	md.htmlStash.reset()
	print('Ouput: ', '\n---------------------\n' + md.convert(src) + '\n---------------------')
