Reverse String Template
Extract values from structured strings. This module used regular expressions under the covers while providing a simpler template stile syntax for specifying patterns.
Pattern matching is a bit touchy 🤡. If the result is unexpectedly null
, it means the string wasn't sufficiently matched.
This work was derived from laktek/extract-values 🙏.
Examples
var tmpl = >> "year": "2012" "month": "08" "day": "12" "title": "test" >> "name": "John Doe" "email": "john@example.com" "url": "http://example.com" >> "from": "4th October" "to": "10th October" >> "quantity": "1500" "from_unit": "grams" "to_unit": "kilograms"
How to Use
Install as a NPM package
npm install reverse-string-template
- Then
require
in your project.
Unit Tests
Run npm test
.
Template ✓ lakteks original test cases should pass ✓ should output expected values 2 passing
Options
whitespace - normalizes the whitespace in the input string, so it can be aligned with the given pattern. You can define the number of continous whitespaces to contain in the string. Making it zero (0) will remove all whitespaces.
lowercase - converts the input string to lowercase before matching.
delimiters - If specify the delimiters used in the pattern to define the values. Default delimiters are {{
and }}
.
lazy_delimiters - If specify the lazy delimiters used in the pattern to define the values. Default delimiters are {%
and %}
. Lazy delimiator produce matchers using lazy matching (instead of greedy).
