envtrace

all the convenience of xtrace + debug in a single package

1. Let's say you want to be able to add logging a la debug and your application is called dope :

``js
DEBUG=dope node my-file.js
`

2. Use envtrace just like you would use debug:

`js
// my-file.js
import { pipe } from 'ramda'
import { envtrace } from 'envtrace'

const ntrace = envtrace('dope')

const myFunction = pipe(
ntrace('input'),
x => x * 2,
ntrace('output')
)
`

3. Wanna use multiple loggers? That's easy:

`js
// example-complex.js

const { pipe } = require('ramda')
const N = require('./envtrace')

const log = N.complextrace('example', [
'info',
'warn',
'detail',
'error'
])

const example = () => {
pipe(
log.info('input'),
x => x * 2,
log.warn('twice'),
x => x * 3,
log.detail('deets'),
x => x * 4,
log.error('nice'),
x => x * 5,
log.info('output')
)(10)
}
example()
`

Then the above can be run with DEBUG=example:* node example-complex.js and it will print:

`
example:info input 10 +0ms
example:warn twice 20 +0ms
example:detail deets 60 +0ms
example:error nice 240 +0ms
example:info output 1200 +3ms
