[Query] Inspect Recursive Functions

Determine whether functions are recursive
This query is requested with the type inspect-recursion.
Run in the REPL: :query @inspect-recursion [(<crit>;...)] <code | file://path>

With this query you can identify which functions in the code are recursive. Please note, that functions that may be recursive due to indirect calls are also considered recursive.

Using the example code fact <- function(n) { if(n <= 1) 1 else n * fact(n - 1) } the following query returns the information for all identified function definitions whether they are recursive:

[ { "type": "inspect-recursion" } ]

(This can be shortened to @inspect-recursion when used with the REPL command :query).

Results (prettified and summarized):

Query: inspect-recursion
  - Function 21 (1.9-57) is recursive

{"inspect-recursion":{".meta":{},"recursive":{"21":true}},".meta":{}}

fact <- function(n) { if(n <= 1) 1 else n * fact(n - 1) }

This query also supports a slicing criterion based query mode that only returns information for functions matching the given criteria:

[ { "type": "inspect-recursion",   "filter": [ "1@function" ] } ]

(This can be shortened to @inspect-recursion (1@function) "fact <- function(n) { if(n <= 1) 1 else n * fact(n - 1) }" when used with the REPL command :query).

Results (prettified and summarized):

Query: inspect-recursion
  - Function 21 (1.9-57) is recursive

{"inspect-recursion":{".meta":{},"recursive":{"21":true}},".meta":{}}

fact <- function(n) { if(n <= 1) 1 else n * fact(n - 1) }
