Package Exports
- jsep
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jsep) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
##jsep: A JavaScript Expression Parser jsep is a simple expression parser written in JavaScript. It can parse JavaScript expressions but not operations. The difference between expressions and operations is akin to the difference between a cell in an Excel spreadsheet vs. a proper JavaScript program.
###Why jsep? I wanted a lightweight, tiny parser to be included in one of my other libraries. esprima and other parsers are great, but had more power than I need and were way too large to be included in a library that I wanted to keep relatively small.
jsep's output is almost identical to esprima's, which is in turn based on SpiderMonkey's.
###Custom Build First, install Grunt. While in the jsep project directory, run:
npm install .
gruntThe jsep built files will be in the build/ directory.
###Usage
####Client-side
...
var parse_tree = jsep("1 + 1");
####Node.JS
First, run npm install jsep. Then, in your source file:
var jsep = require("jsep");
var parse_tree = jsep("1 + 1");###License jsep is under the MIT license. See LICENSE file.
###Thanks Some parts of the latest version of jsep were adapted from the esprima parser.
