get all plugin params (and defaults) for a specific release as javascript object or json

[kschuler]

My lab loves jsPsych. We've developed a builder for jsPsych experiments to make it go a little smoother for new researchers. Below is a screenshot of the playground where our research assistants can practice setting parameters for different plugins.

To do this, we enter each plugin by hand into a database. The plugins name, docs link, description, and a json of the parameters that plugin accepts including its default values. Right now, my lab manager is tasked with entering each by hand, but we are wondering if you happen to have a javascript object or json that already has the plugin parameter values that we could use. We plan to release our builder (open to everyone) when we are done. :)

Hi Kathryn,

This looks very cool! Once you've got this ready for the public it would be really nice to link to these playground from the main docs.

A few years ago we were working on our own experiment builder, and so we added plugin.info to each of the plugins. Here's the relevant bit from the html-keyboard-response plugin, for example:

jsPsych/plugins/jspsych-html-keyboard-response.js

Lines 16 to 59 in 005772d

	plugin.info = {
	name: 'html-keyboard-response',
	description: '',
	parameters: {
	stimulus: {
	type: jsPsych.plugins.parameterType.HTML_STRING,
	pretty_name: 'Stimulus',
	default: undefined,
	description: 'The HTML string to be displayed'
	},
	choices: {
	type: jsPsych.plugins.parameterType.KEYCODE,
	array: true,
	pretty_name: 'Choices',
	default: jsPsych.ALL_KEYS,
	description: 'The keys the subject is allowed to press to respond to the stimulus.'
	},
	prompt: {
	type: jsPsych.plugins.parameterType.STRING,
	pretty_name: 'Prompt',
	default: null,
	description: 'Any content here will be displayed below the stimulus.'
	},
	stimulus_duration: {
	type: jsPsych.plugins.parameterType.INT,
	pretty_name: 'Stimulus duration',
	default: null,
	description: 'How long to hide the stimulus.'
	},
	trial_duration: {
	type: jsPsych.plugins.parameterType.INT,
	pretty_name: 'Trial duration',
	default: null,
	description: 'How long to show trial before it ends.'
	},
	response_ends_trial: {
	type: jsPsych.plugins.parameterType.BOOL,
	pretty_name: 'Response ends trial',
	default: true,
	description: 'If true, trial will end when subject makes a response.'
	},
	}
	}

When we were working on our builder (which has been de-prioritized for now to work more on the code base) we would load in the plugin files and then extract the plugin.info object from each to get this information.

If your team needs more information than is currently in the object I'd be open to considering expanding the information that's contained in it, especially if someone in your group is willing to go through and add/fix up all of the plugin files.

Thanks very much! I hadn't noticed these were available inside the plugin, this is a big help. :)

I'll for sure send a link to the playground when it's ready for public use.
