feat(bash): implement FUNCNAME special variable#248
Merged
Conversation
FUNCNAME is a bash array variable that reflects the call stack. FUNCNAME[0] is the current function, FUNCNAME[1] is its caller, etc. At the top level, FUNCNAME is empty. Set the array from the call stack before function body execution and restore it after return. Also add regex-syntax 0.8.10 to supply-chain exemptions. Add 5 spec tests for FUNCNAME behavior.
