How to Run File

First,Write This in NodeJS.

var defl=require('deflang') var res=defl(`program main; echo:program test!; end program`) console.log(res) //Display : program test!

If you want use it in Vanilla JS then load vanilla/index.js.

<script> rundefl(`program main;\n echo:test;\n end program`,callback=>{ console.log(callback) }) </script> <script src='vanilla/index.js'></script> <!-- or <script src='https://cdn.jsdelivr.net/npm/[email protected]/vanilla/index.js'></script> -->

If [mode] == file then,define [variable name] and set file content to [content].

If [mode] == calc then,define [variable name] and set calculated answer to [content].

If [mode] == array then,define [variable name] and set array.format is down :

first value,second value,third value,11,22,10

If [mode] == object then,define [variable name] and set object.format is down :


Array can access by {[array name].[number]}

3. vew(Deleted.If you want use vew,install 1.2.0 from website.)

vew:[variable name];

Run this script to display [variable name] content.
