xcsrz / getContentHash.py

Last active December 20, 2021 20:19

Python port of the getContentHash() function from PHP's Composer. Useful when updating composer.lock from php when composer is available. Granted this "shouldn't be done" and is "doing it wrong", but sometimes running composer commands in your deployment chain is overkill and redundent.

	import hashlib
	from json import dumps
	from collections import OrderedDict

	# composerFileContents should be the dict version of the composer.json file
	def getContentHash(composerFileContents):
	relevant = OrderedDict((key, composerFileContents[key]) for key in composerFileContents.keys() if key in ['name','version','require','require-dev','conflict','replace','provide','minimum-stability','prefer-stable','repositories','extra'])

	if 'config' in composerFileContents and 'platform' in composerFileContents['config']:
	relevant['config']['platform'] = composerFileContents['config']['platform']

xcsrz / webtask-backup.py

Created May 10, 2021 21:05

Backup your webtask code. Can be used to make sure you have the latest version of your code locally, or used to backup in case at some point webtask.io ceases to function. Considering they very recently started failing to install new npm modules, this could be any point now I fear.

	import subprocess
	from json import dumps

	# NOTE: Files will be written to the current directory, without any checks to prevent overwriting. Archiving and/or version control are not considered here, but highly encouraged.

	# get a list of all webtasks for the current user
	list_request = subprocess.run(['wt', 'ls'], stdout=subprocess.PIPE, text=True)
	# transform that output into a list of task names
	tasks = [ ln.replace('Name:','').strip() for ln in list_request.stdout.split("\n") if 'Name:' in ln ]

xcsrz / pemify-your-private-ssh-key.sh

Created April 5, 2020 19:31

This one command is so hard to track down every 3 years when I need it. So many posts incorrectly insist the private key is in PEM format already. In truth, it depends on how the key pair was created (openssl vs ssh-keygen).

	# NOTE: this updates the file in place, do you have a backup?
	ssh-keygen -p -m PEM -f ~/.ssh/id_rsa
