Comparison of configuration file languages

We need to PEPify a static format for writing down bootstrap information in Python source trees. The initial target is a list of PEP 508 package requirement strings. It's possible that in the future we might want to add more features like a build system backend specification (as in PEPs 516, 517), or an extension namespace feature to allow third-party developer tools (flit, pytest, coverage, flake8, etc.) to consolidate their configuration in this file in a systematic

UDF creation

Current state

Right now there are a few ways we can create UDF:

With standalone function:

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

	#!/bin/bash
	## Timer Function - displays the timed duration between start and stop ##
	# example:
	# Timer start
	# Script_Cmds
	# Timer stop


	Timer() {
	## Set a timer to display duration ##

	`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`

	What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.

	Now let’s extract the certificate:

	`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`
