eglint  _{^{an intuitive, unopinionated code formatter}}

format one to format it all

Many tools exist today to format code, but they generally have one of two problems: they're opinionated (like prettier), or they're hard to configure (like eslint).

eglint is an unopinionated code formatter that doesn't need configuration. To specify your code style, you simply supply examples of correctly formatted code.

No configuration beyond the reference file is used.

// reference file [containing examples of correct format]
let x = [ 1, 2, 3, 4 ];

let y = [
  "a",
  b + c,
  d.e,
];

// subject file [to be formatted by eglint]
const
  foo
= [ "abc"   
 , "def" ]
 ; let bar  =[1+ 2*3, [4,5],    ]

// output file [from eglint]
const foo = [
  "abc",
  "def",
];

let bar = [ 1 + 2 * 3, [ 4, 5 ] ];

In the example above, many issues are fixed, including contextual whitespace, trailing commas, and semicolons (both misplaced and missing) — all from the simple reference file.
