SOURCE

The built-in source function in HookScript is used for pulling data. Data is lazy loaded into a table, along with the source's type information. The data is not retrieved until the table is used in a context that requires the data (e.g., a for-of loop).

Datasets

HookScript has three built-in datasets that are always available. To access these datasets, prefix their names with dataset::

• source("dataset:iris"): retrieves the popular iris dataset
• source("dataset:cars"): retrieves the popular cars dataset
• source("dataset:titanic"): retrieves the popular titanic dataset

var iris = source("dataset:iris")
var total = 0
var i = 0
for sample of iris:
    i++
    total += sample["sepal_length"]
end
print("Average sepal length:", total / i)

Local (not available in browser)

When running HookScript locally, you can pull data from the local file system. To access local files, prefix the absolute file path with local::

• source("local:/absolute/path/to/file.csv"): retrieves a local file

Hub (not available in browser)

When connecting HookScript with the Hub, you can pull data from other sources in the Hub. To access sources in the hub, provide their domain location:

• source("/public/domain/source"): retrieves a source from the hub
