cast option should be function

[tomhelmer]

Hi

I have a CSV with booleans represented as the string true or false. I wan't these to be casted to booleans. The 'cast' option on payload defaults to true. The default cast function in csv-parse don't handle casting true|false to booleans. According to the documentation:

https://csv.js.org/parse/options/cast/

.. this can be the function handling the casting.

It would be nice if you injected a cast function handling true|false. It looks like you would have to copy the default casting functionality from csv-parse as well.. You can't stack your own parse on top of the default.

I have created a fork with a custom cast function like this :

if (csvOpts.cast) { csvOpts.cast = function(value, context) { if (isFinite(value) && !value.startsWith('0')) { return parseInt(value); } else if (_.toLower(value) === 'false') { return false; } else if (_.toLower(value) === 'true') { return true; } else { return value; } } }

• fields with integers not starting with a 0 are casted to integers
• true|false ( case-insensitive) is casted to booleans
• everything else is returned as is

This is matching my dataset, others might have floats, dates etc. It would be nice if the casting could be defined in the config file per field.
