String Replacer

Tiny and fast string replacer utility.

Usage

const strep = require('strep'),
      great = strep('{1} {0}!')
       
console.log(great([ 'World', 'Hello' ]))

Hello World!

Objects are supported as well:

const format = strep('{first} {last} ({nick})'),
      name = {
          nick: 'Johnny',
          first: 'John',
          last: 'Doe'
      }

console.log(format(name))

John Doe (Johnny)

Custom placeholders

By default the following regexp is employed to find placeholders in a format string: /{([a-zA-Z0-9_]+)}/g You are able to override it globally or per call to use different placeholders.

strep.pattern = /\{{\s*([a-z]+)\s*}}/g // override globally

const mustache = strep('Hello {{ name }}!'),
      bash     = strep('$0 is my $1', /\$([0-9]+)/) // override just for this call

console.log(bash([ 'Buggy', 'cat' ]))
console.log(mustache({ name: 'Buggy' }))

Buggy is my cat.
Hello Buggy!

Note: mind the capturing group in those regexps. Those are required to work properly.
