Slim sliminality

Dot composition

f.g.h(x) === f(g(h(x)))

Example

const add1 = x =&gt; x + 1;

Hidden dependencies

Sarah Lim, Northwestern University

Update, September 2019: This Gist detailed an early idea which formed the basis for a major research project. For more information, you can read the resulting full paper, which received Best Paper Honorable Mention at UIST 2018. A tool based on this research is now available on Firefox Nightly.

What are hidden dependencies?

Hidden dependencies between CSS properties are a common source of beginner confusion. For instance, a user might write the following code in order to vertically align some text within a <div>:

Remotes

Upstream vs downstream?

upstream is where you cloned from (origin)
downstream is any project that integrates your work

Origin

These things are equivalent and refer to the branch named master on the remote named origin:

remotes/origin/master
origin/master

LIP: Finding good/relevant papers

Search/read with intentionality

        old <-------------------> new
theoretical <-------------------> system

"Most similar papers" will probably be towards the (new, concrete) end

Build system arguments

Argument	Example	Notes
`cmd`	`['python', '-m', '$project']`	Required if `shell_cmd` is empty; overridden by `shell_cmd`; searched in `PATH`
`shell_cmd`	`yarn build`	Required if `cmd` is empty; overrides `cmd`
`working_dir`	??	Temporarily change to directory before executing `cmd`
`env`	`{ EDITOR: 'vim' }`?	Can merge in a dictionary before passing to `cmd`; expands environment variables.
`shell`	`true`	Runs `cmd` through the shell if `true`; noop if `shell_cmd` is used
`path`	`/User/sarah/git`	Used by `cmd`; expands environment variables.

The Missing README for JavaScript Projects

This README provides general instructions for installing Node.js and npm ecosystem projects from GitHub.

Many project READMEs assume a baseline level of user knowledge, but the following "Getting Started" section isn't very helpful to an absolute beginner:

Getting Started
npm install

	#[no_mangle]
	pub extern "C" fn double_subtract5_add1(x: i32) -> i32 {
	let result = double(x) + negate(5) + 1;
	return result;
	}

	#[no_mangle]
	pub fn double(x: i32) -> i32 {
	return x * 2;
	}

	var config = {
	templateSheetName: 'TEMPLATE',
	dateFormat: 'ddd M/d',
	sheetTitlePrefix: 'Week ',
	daysPerSheet: 7,
	showLatestOnLeft: true,
	dateHeaderRow: 1,
	};

	// Get the first sheet from the given spreadsheet.
