feat: Support custom col_sep for CSV data files

[captn3m0]

Summary

CSV data files should support custom separators.

Motivation

I have a CSV file with ; as the column separator, but this configuration cannot be passed to Jekyll.

Guide-level explanation

Similar to #8858, setting up a col_sep configuration in the csv_reader should support CSV files with a custom column separator.

Reference-level explanation

Drawbacks

Can't think of any reason.

Unresolved Questions

It might be worth it to support more CSV reader configuration options here . The complete list is

:col_sep -> ","
:row_sep -> :auto
:quote_char -> '"'
:field_size_limit -> nil
:converters -> nil
:unconverted_fields -> nil
:headers -> false
:return_headers -> false
:header_converters -> nil
:skip_blanks -> false
:force_quotes -> false
:skip_lines -> nil
:liberal_parsing -> false
:quote_empty -> true

This issue has been automatically marked as stale because it has not been commented on for at least two months.

The resources of the Jekyll team are limited, and so we are asking for your help.

If this is a bug and you can still reproduce this error on the latest 3.x-stable or master/main branch, please reply with all of the information you have about it in order to keep the issue open.

If this is a feature request, please consider building it first as a plugin. Jekyll 3 introduced hooks which provide convenient access points throughout the Jekyll build pipeline whereby most needs can be fulfilled. If this is something that cannot be built as a plugin, then please provide more information about why in order to keep this issue open.

This issue will automatically be closed in two months if no further activity occurs. Thank you for all your contributions.
