profile for debug

Profile each pipeline element in a closure.

Signature

> profile (closure) --source --values --max-depth

Parameters

• closure: the closure to run
• --source (-): Collect source code in the report
• --values (-): Collect values in the report
• --max-depth {int}: How many levels of blocks to step into (default: 1)

Notes

The command collects run time of every pipeline element, recursively stepping into child closures until a maximum depth. Optionally, it also collects the source code and intermediate values.

Current known limitations are:

• profiling data from subexpressions is not tracked
• it does not step into loop iterations

Examples

Profile some code, stepping into the spam command and collecting source.

> def spam [] { "spam" }; profile {|| spam | str length } -d 2 --source
