Snap2JS can be installed using `npm` as follows: 8 | 9 | ``` 10 | npm install -g snap2js 11 | ``` 12 | 13 | Next, you can compile your favorite Snap! application by first exporting it to xml then using snap2js to compile it to a js file! A "hello world" example project is provided [here](https://github.com/NetsBlox/Snap2Js/blob/master/test/test-cases/projects/hello-world.xml). 14 | 15 | ``` 16 | snap2js hello-world.xml 17 | node hello-world.js 18 | ``` 19 | -------------------------------------------------------------------------------- /bin/snap2js: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env node 2 | 3 | const prog = require('caporal'); 4 | const version = require('../package.json').version; 5 | const snap2js = require('..'); 6 | const path = require('path'); 7 | const fs = require('fs'); 8 | const exists = require('exists-file'); 9 | const browserify = require('browserify'); 10 | const BROWSERIFY_OPTS = { 11 | noParse: [ undefined ], 12 | extensions: [], 13 | ignoreTransform: [], 14 | fullPaths: false, 15 | builtins: false, 16 | commondir: false, 17 | bundleExternal: true, 18 | basedir: undefined, 19 | browserField: false, 20 | transformKey: undefined, 21 | dedupe: true, 22 | detectGlobals: true, 23 | insertGlobals: false, 24 | insertGlobalVars: 25 | { 26 | process: undefined, 27 | global: undefined, 28 | 'Buffer.isBuffer': undefined, 29 | Buffer: undefined 30 | }, 31 | ignoreMissing: false, 32 | debug: false, 33 | standalone: undefined 34 | }; 35 | const {promisify} = require('util'); 36 | const readFile = promisify(fs.readFile); 37 | const writeFile = promisify(fs.writeFile); 38 | 39 | prog 40 | .version(version) 41 | .description('A tool to compile Snap! xml files to JavaScript') 42 | .argument('', 'Snap xml files to compile') 43 | .option('-i,--interpret') 44 | .option( 45 | '--args [inputs]', 46 | 'Comma separated list of arguments (if interpreting a serialized function)' 47 | ) 48 | .option('--output ', 'Output directory', fileExists, '.') 49 | .option('--context ', 'Context to use', isContext, 'basic') 50 | .action((args, opts, logger) => { 51 | if (opts.interpret) { 52 | if (args.files.length > 1) logger.warn(`Only interpretting ${args.files[0]}`) 53 | return interpretFile(args.files[0], opts, logger); 54 | } else { 55 | return Promise.all(args.files.map(filename => saveToFile(filename, opts, logger))); 56 | } 57 | }); 58 | 59 | async function compileFile(filename, opts, logger) { 60 | const contents = await readFile(filename) 61 | return snap2js.transpile(contents); 62 | } 63 | 64 | async function saveToFile(filename, opts, logger) { 65 | const outfile = path.join(opts.output, path.basename(filename).replace(/\.[a-zA-Z0-9]+$/, '.js')); 66 | const tmpfile = outfile + '.tmp'; 67 | const context = opts.context; 68 | 69 | logger.debug('compiling ' + filename + ' to ' + outfile); 70 | const fn = await compileFile(filename, opts, logger); 71 | const relPath = path.resolve(`${path.dirname(__dirname)}/src/context/${context}`); 72 | const contextPath = path.relative(path.resolve(opts.output), relPath); 73 | const code = `(${fn.toString()})(require('./${contextPath}'))`; 74 | await writeFile(tmpfile, code); 75 | 76 | const b = browserify([tmpfile], BROWSERIFY_OPTS); 77 | const outputStream = fs.createWriteStream(outfile); 78 | 79 | b.bundle().pipe(outputStream); 80 | outputStream.on('error', err => logger.warn(err)); 81 | 82 | outputStream.on('close', () => { 83 | logger.debug('finished compiling ' + outfile); 84 | logger.debug('removing ' + tmpfile); 85 | fs.unlinkSync(tmpfile); 86 | }); 87 | } 88 | 89 | async function interpretFile(filename, opts, logger) { 90 | const context = opts.context; 91 | const contents = await readFile(filename, 'utf8'); 92 | const fn = await snap2js.compile(contents); 93 | const env = require(`../src/context/${context}`); 94 | 95 | const result = await fn(env); 96 | if (isFunction(contents)) { 97 | const args = opts.args ? parseFnArgs(opts.args) : []; 98 | try { 99 | const fnOutput = await result.apply(null, args); 100 | console.log(fnOutput); 101 | return fnOutput; 102 | } catch (err) { 103 | console.log(err.stack); 104 | process.exit(1); 105 | } 106 | } 107 | return result; 108 | } 109 | 110 | function parseFnArgs(argString) { 111 | try { 112 | return JSON.parse(argString); 113 | } catch (err) { 114 | return argString.split(','); 115 | } 116 | } 117 | 118 | function isFunction(data) { 119 | return data.trim().startsWith(' name.replace(/\.js$/, '')); 133 | 134 | var isValid = contexts.find(filename => filename === name.toLowerCase()); 135 | 136 | if (!isValid) { 137 | throw new Error(`Invalid context: ${dir}.
