solmeister

Edit your solidity code by applying transforms on its (Spider Monkey compliant) AST's nodes.

Installation

npm install solmeister

Usage

let solmeister = require ('solmeister');

Available methods

-> version (): Version information

-> edit (code, callback): code is the source code on which to operate (This can be a String or a Buffer object) & callback is the function solmeister calls upon entering every Node during the AST treversal. The callback is passed the node just entered.

Properties of node

-> node.parent: access the parent node of the current node

-> node.getSourceCode (): get the source code of the current node

-> node.transform (finalCode): apply the transform on the node by replacing its source code with finalCode.

Example

/**
 * Append '.00' to every integer and change every Identifier name to lowercase, like:
 * 178 --> 178.00
 * hasEther --> hasether
 */
 
'use strict';
 
let i = require ('solmeister'),
    code = 'contract Visual {\n\tuint[] x = [13,212,334,44,52];\n\tMIxEDCaSEvAr = 100;\n}';
 
let output = i.edit (code, function (node) {
 
    if (node.type === 'Literal' && typeof node.value === 'number' && node.value === parseInt (node.value)) {
 
        node.transform (node.getSourceCode () + '.00');
    
    } else if (node.type === 'Identifier') {
    
        node.transform (node.getSourceCode ().toLowerCase ());
    
    }
 
});
 
console.log ('Version: ', i.version);
console.log (output);

Code before transform

contract Visual {
    uint[] x = [13,212,334,44,52];
    MIxEDCaSEvAr = 100;
}

Code after transform

contract Visual {
    uint[] x = [13.00,212.00,334.00,44.00,52.00];
    mixedcasevar = 100.00;
}
