Plugins
Check out the plugin example in the examples directory.
Plugins are node modules that expose a function which accepts the REPL context. Attach variables and functions to the context to make them accessible at run-time.
module.exports = function(context) {
context.getText = function() {
//
// Access the jQuery object from within the plugin.
//
context.$('p').each(function() {
out.push(this.text());
});
//
// The return value will be written to standard out.
//
return out.join(' ');
};
};
Require your plugin using the --require
option.
$ screpl http://example.com --require plugin.js
request loaded with 200
use the variable `$` to access the result
> getText()
'\nWelcome to exmaple.com.\nChances...'
