Function and operator catalog
The catalog and the operator table are closed and enumerated — new capability is added as a
named, typed entry, and this page is regenerated from that entry, never hand-edited. Every example
shown below is executed as an assertion by the engine's own test suite (examples.test.ts), so a
result shown here is a result the engine actually produces for that input.
Catalog version: 2.0.0
Catalog content hash: ad6ea5b0ea1d49acd7b41a5fa9642bf99bab0e78db3768b2a2fc0dcf17c85597
Hash scope: every .ts file under packages/engine/src/analysis, recursively, excluding *.test.ts files and catalog-hash.ts itself — the whole analysis tree, not only the catalog directory, because an operator implementation or a shared helper outside the catalog directory can also change what an expression evaluates to
The catalog is split across seven pages, one per group below — open one directly, or use the name index further down to jump straight to the entry you need.
| Group | Entries | Holds |
|---|---|---|
| Aggregation | 5 | SUM, AVG, MIN, MAX, COUNT |
| Collections | 10 | GROUPBY, FIND_BY, GET, ARGS, SLICE, LENGTH, INCLUDES, JOIN, COMPACT, FLATTEN |
| Number | 3 | ABS, ROUND, PARSENUMBER |
| Logic & Fallback | 2 | IF, COALESCE |
| String | 12 | UPPER, LOWER, TRIM, SUBSTRING, SPLIT, REPLACE, CONCAT, INDEXOF, LASTINDEXOF, PADSTART, PADEND, REPEAT |
| Date | 13 | NOW, TODAY, DATE, YEAR, MONTH, DAY, ADD_DAYS, ADD_MONTHS, DIFF_DAYS, START_OF_DAY, END_OF_DAY, PARSEDATE, FORMATDATE |
| Operators & Precedence | 25 | Every condition operator ENG-08 enumerates, plus the parser's operator precedence table |
