Capture variable assignments in a Perl eval
- by Bruce
I would like to be able to capture variable assignments from a Perl eval. That is, to determine what variable names have been assigned to within the code and extract their value.
For example if I run:
eval '$foo=42; $bar=3.14;'
The result of the eval is 3.14 (the last value evaluated), but I would also like to be able to determine the names "$foo" and "$bar" and their values (without knowing the names in advance).
I have read up on a couple of ways of inserting variables into the eval block, through Safe and Eval::Context, but not yet any way of extracting them. I am more familiar with Python's eval/exec which have built in support for this.
