let charseq = new CharSequence('This is a string');
while (!charseq.eof()) {
console.log(charseq.read(1));

Command Line Argument Parser (cmd.js)
Provide functions to work with Command Line arguments.

const { Cmd } = require('@ntlab/ntlib');
Cmd.addBool('help', 'h', 'Show program usage').setAccessible(false);
Cmd.addVar('something', 's', 'Something description', 'some-argument');
if (!Cmd.parse() || (Cmd.get('help') && usage())) {
process.exit();
}
/* do something here */
function usage() {
console.log('Usage:');
console.log(' node %s [options]', path.basename(process.argv[1]));
console.log('');
console.log('Options:');
console.log(Cmd.dump());
console.log('');
return true;
}
CLI or HTTP Executor (command.js, httpcmd.js)
Execute a Command Line Interface (CLI) or HTTP command.
const { CommandExecutor } = require('@ntlab/ntlib');

bin: 'php',
cli: 'path/to/php.file.to.execute.php',
args: [
'-f',
'%CLI%',
'--',
'%DATA%'
]
}
const p = CommandExecutor(cmd).exec({DATA: 'some-data'});
p.on('exit', (code) => {
/* do something on exit */
});
p.stdout.on('data', (line) => {
/* do something on stdout data */
});
p.stderr.on('data', (line) => {
/* do something on stderr data */
});

message: 'message',
raw: Stringify.raw('`string`'),
})); // {message: 'message', raw: `string`}
Token Processing (token.js)
Provide an utility to parse string into tokens.
const { Token } = require('@ntlab/ntlib');
console.log(Token.split('1, 2, (1, "ABC")')); // [1, 2, [1, "ABC"]]
App Utility (util.js)
Internally used by CLI/HTTP Executor, also provide a small set of common functions.
const { AppUtil } = require('@ntlab/ntlib');
console.log(AppUtil.trans('Translate %ME%', {ME: '123'})); // Translate 123
