Each page will +get `page.earlier` and `page.later` variables that contain the pages with +earlier and later dates, respectively. +### `weight` +This will be sort all pages by their `weight` field, from lightest weight +(at the top of the list) to heaviest (at the bottom of the list). Each +page gets `page.lighter` and `page.heavier` variables that contain the +pages with lighter and heavier weights, respectively. + +When iterating through pages, you may wish to use the Tera `reverse` filter, +which reverses the order of the pages. Thus, after using the `reverse` filter, +pages sorted by weight will be sorted from lightest (at the top) to heaviest +(at the bottom); pages sorted by date will be sorted from oldest (at the top) +to newest (at the bottom). + +`reverse` has no effect on `page.later`/`page.earlier`/`page.heavier`/`page.lighter`. + +## Sorting Subsections +Sorting sections is a bit less flexible: sections are always sorted by `weight`, +and do not have any variables that point to the next heavier/lighter sections. + +Based on this, by default the lightest (lowest `weight`) subsections will be at +the top of the list and the heaviest (highest `weight`) will be at the top; +the `reverse` filter reverses this order. + +**Note**: Unlike pages, permalinks will **not** be used to break ties between +equally weighted sections. Thus, if the `weight` variable for your section is not set (or if it +is set in a way that produces ties), then your sections will be sorted in +**random** order. Moreover, that order is determined at build time and will +change with each site rebuild. Thus, if there is any chance that you will +iterate over your sections, you should always assign them weight. diff --git a/docs/content/documentation/templates/pages-sections.md b/docs/content/documentation/templates/pages-sections.md index 6dcf7ac..297c95b 100644 --- a/docs/content/documentation/templates/pages-sections.md +++ b/docs/content/documentation/templates/pages-sections.md @@ -32,9 +32,12 @@ extra: HashMap; word_count: Number; // Based on https://help.medium.com/hc/en-us/articles/214991667-Read-time reading_time: Number; -// `previous` and `next` are only filled if the content can be sorted -previous: Page?; -next: Page?; +// `earlier` and `later` are only populated if the section variable `sort_by` is set to `date` +earlier: Page?; +later: Page?; +// `heavier` and `lighter` are only populated if the section variable `sort_by` is set to `weight` +heavier: Page?; +lighter: Page?; // See the Table of contents section below for more details toc: Array
