Soupault 2.6.0 release

Estimated reading time: less than a minute.


Soupault 2.6.0, is available for download from my own server and from GitHub releases. It's a relatively small release with a few bug fixes and one new feature: configurable index entry sorting method.

Bug fixes

Configurable entry sorting

Originally, soupault assumed that the index entry sort key field is some kind of a date. You could configure supported date formats using the index_date_formats option, and it would attempt to parse every value as a date, or resorted to lexicographic comparison if parsing failed.

A lot of websites with auto-generated index pages are blogs, so that assumption wasn’t terribly unreasonable. However, it still was a rather inflexible design.

Now there’s a new option: sort_type that can have three values: calendar (the default), numeric, and lexicographic.

The calendar mode matches the old behaviour: it tries to parse a field value as a date according to supported index_date_formats. Invalid values are considered “older” than any valid values. Between themselves, invalid values are compared lexicographically.

In the numeric mode, soupault will try to parse values as integer numbers. Invalid values are considered “less” than any valid values. This is useful in cases when you want to order pages or sections by “weight”.

In the lexicographic mode, soupault will simply compare values as strings.

There’s also a new strict_sort option. If it’s set to true, then soupault will log an error and terminate if it finds a value that cannot be parsed.


  sort_type = "numeric"
  strict_sort = true


Thanks for testing and suggestions to Anton Bachin and Javier Chávarri who now use soupault in the documentation workflows for Dream and Melange respectively.
