Enrich data using regular expressions

Installation

Install this plugin in the same environment as Datasette.

datasette install datasette-enrichments-re2

Usage

This enrichment allows you to run a regular expression against a column and perform one of the following:

• Execute a search and replace against that column
• Extract the first matching result and store that in the specified column (adding a column if necessary)
• Extract all matching results and store them as a JSON array in the specified column. If the regular expression uses named capture groups this will be an array of objects, otherwise it will be an array of strings.
• Execute a regular expression with named capture groups and store the results in multiple columns, one for each of those named groups
