Backport #7157: Ruby ignores Kernel#gsub block

• Status: Closed
• Assignee: usa (Usaku NAKAMURA)

[popoxee (Bruce Metz)]

When working with command line and use Kernel#gsub, ruby ignores the block if given.

Reproduce code:

Test text file:
File name:
test
File Content:
test

Test Command line input:

ruby -pe 'gsub(/t([a-z])s/){"d"+$1.capitalize}' test

Expected output:

dEt

Actual output:

#Enumerator:0x00000001c78520

The docs for Kernel#gsub mention:
"Equivalent to $.gsub..., except that $ receives the modified
result. Available only when -p/-n command line option specified."
