[Query] Function Info

Generated from 'wiki-query.ts' on 2026-09-10, 07:04:46 UTC (v2.15.8), do not edit directly.

Function Info Query ^[overview]

Reports where a function name comes from: which packages export it, their signature, and whether flowR itself has a built-in definition for it.
This query is requested with the type function-info.
Run in the REPL: :query @function-info <name> [<package>...]

This query answers "where does this function come from?" for a bare name, combining two sources flowR otherwise consults separately: the signature database (which packages export the name, and their signature/definition site) and flowR's own built-in configuration (whether flowR models the name itself, and how).

Given a base-R name such as sd:

[
  {
    "type": "function-info",
    "name": "sd"
  }
]

The packages property restricts which packages are considered (every exporting package is checked by default), which is useful once a name is exported by more than one package on CRAN. A name flowR models itself, like get, also reports the built-in's processor, its evaluation handler (if it folds to a constant), and the semantic tags flowR states for it:

[
  {
    "type": "function-info",
    "name": "get"
  }
]

Note

To find out what a script uses, reach for the Dependencies Query; to inspect a specific package/version in the database directly, reach for the Signature Query. In the REPL, :signature info <name> is a shorthand for this query.

Implementation Details

Responsible for the execution of the Function Info Query query is executeFunctionInfoQuery in ./src/queries/catalog/function-info-query/function-info-query-executor.ts.
