tersify

Create a readable terse representation of the subject.

You can specify maxLength to further trim the resulting string.

You can also override the result by providing your own tersify() function on the subject.

import { tersify } from 'tersify'

// `() => 'foo'`
tersify(() => { return 'foo' })

// `fn(x, y) { return x + y; }`
tersify(function (x, y) { return x + y })

// `fn foo(y) { return y++; }`
tersify(function foo(y) { return y++ })

// Change result to 80 character long.
// result will have `...` to indicate info missing.
// e.g. `{ a: 'a', ... }`
tersify({...}, { maxLength: 80 })

// '{ a: 1 }`
tersify({ a: 1 })

// `() => Sym(abc)`
tersify(() => { return Symbol.for(abc) })

tersible

Inject a tersify() function to the subject.

import { tersible } from 'tersify'

const increment = tersible(a => a + 1, () => 'a++')
increment.tersify() // 'a++'

// `{ a: 1 }`
tersible({ a: 1 }, function () { return `{ a: ${this.a} }`}).tersify()

const decrement = tersible(a => a--, 'a--')
decrement.tersify() // 'a--'

// `a: 10`
tersible({ a: 1 }, options => `a: ${options.maxLength}`).tersify({ maxLength: 10 })

Tersiblized

Mixin Tersible to a class.

import { Tersiblized } from 'tersify'

class Foo { a = 1 }
class Boo extends Tersiblized(Foo, function() { return `{ a: ${this.a} }` }) { }

const boo = new Boo()
boo.a = 3
boo.tersify() // '{ a: 3 }'
