Space Lua Integrated Query (SLIQ) — query syntax for SilverBullet data.
Syntax:
from = index.objects("") [where ] [order by [asc|desc] [nulls first|last] [, ...]] [group by [, ...]] [having ] [select ] [limit [, ]] [offset ]
Clauses can appear in any order. Only from is required.
Always use variable binding: from p = index.pages() (not from index.pages()).
Type-specific helpers: index.pages(tag?), index.contentPages(), index.metaPages(),
index.aspiringPages(), index.tasks(tag?), index.headers(tag?), index.items(tag?),
index.paragraphs(tag?), index.tables(tag?); otherwise index.objects("tag").
Operators: ==, ~= (not equal), <, >, <=, >=, and, or, not String: s:startsWith("x"), s:endsWith("x"), s:contains("x") Tables: table.includes(t, val), table.select(t, "k1", "k2", ...)
Grouping:
After group by, each row has key (the group key) and group (array of items).
Use #group for count. Multi-key: group by p.x, p.y makes key a table ({key[1], key[2]}).
having filters groups after grouping (can use aggregates).
Aggregates (in select/having, with or without group by): count(expr), sum(expr), min(expr), max(expr), avg(expr), array_agg(expr) With ordering: array_agg(p.name order by p.name asc) With filter: count(p.size) filter(where p.size > 100)
Projection: select p.name -- single field select {name=p.name, count=#group} -- construct table select table.select(p, "name", "tags") -- pick specific fields from object
Examples: query 'from t = index.tasks() where not t.done' query 'from p = index.pages() order by p.lastModified desc limit 10' query 'from t = index.tasks() group by t.page select {page=key, count=#group}' query 'from p = index.pages() select table.select(p, "name", "lastModified") limit 5' query 'from l = index.objects("link") where l.toPage == "MyPage"' query 'from p = index.pages() order by p.lastModified desc limit 5 select templates.pageItem(p)'
