POSIX & BSD Standard Command Line Flags & Options

The vital resource for developers creating new command-line tools to learn the wisdom of the ancients.

All programs should universally implement these flags:

-V (uppercase), --version, version
--help, help (also the default if nothing is given)
-- stop processing flags; treat all else as raw arguments

XDG - Base Directory Specification `(extended)`

Directories

Base

The intended use-case for BaseDirectories is to query the paths of user-invisible standard directories that have been defined according to the conventions of the operating system the library is running on.

RSA Private / Pubic key pair

To generate a private / public RSA key pair, you can either use openssl, like so:

$ openssl genrsa -out private.pem 4096  
$ openssl rsa -in private.pem -outform PEM -pubout -out public.pem

Or, you can use the following python script:

	[package]
	name = "test-multipart"
	version = "0.1.0"
	edition = "2021"

	[dependencies]
	axum = { version = "0.6.20", features = ["multipart"] }
	tokio = { version = "1.32.0", features = ["full"] }
	mime = "0.3.17"
	log = "0.4.20"

	-- This is a sample custom writer for pandoc, using Layout to
	-- produce nicely wrapped output.

	local layout = pandoc.layout
	local text = pandoc.text
	local type = pandoc.utils.type

	local l = layout.literal

	-- Table to store footnotes, so they can be included at the end.

	fetch( '/calc.wasm' ).then( ( response ) => {
	return response.arrayBuffer(); // convert stream to ArrayBuffer
	} ).then( ( wasmBuffer ) => {
	return WebAssembly.instantiate( wasmBuffer ); // compile and instantiate WASM module
	} ).then( ( { instance, module } ) => {
	console.log( instance.exports.add( 1, 2 ) ); // 3
	} );
