sUTL 1.0.6

A sUTL implementation for python

# sUTL_py
sUTL Universal Transform Language for Python

This is a python implementation of sUTL. See the [sUTL spec](https://github.com/emlynoregan/sUTL-spec) here.

Import sUTL like this:

from sUTL_py import sUTL

Evaluate a transform like this:

transform = {
"&": "+",
"a": "^@",
"b": 5
}

source = 6

result = sUTL.evaluate(source, transform, {})

# here result is 11

To use library distributions, do the following:

1: Load the libraries. The following loads the core library.

coreString = urllib2.urlopen("http://emlynoregan.github.io/sUTL-spec/sUTL_core.json").read()
distributions = [json.loads(coreString)]

2: Add your transform to a declaration

transform = {
"&": "map_core",
"list": "^@",
"t": {":": {
"&": "+",
"a": "^@.item",
"b": 1
}}
}

declaration = {
"transform-t": transform,
"requires": ["map_core"]
}

3: Compile a set of libraries from the distribution

lib = sUTL.compilelib([declaration], distributions, false)

4: Evaluate your transform

source = [1, 2, 3, 4]

result = sUTL.evaluate(source, transform, lib)

# here result is [2, 3, 4, 5]
