Aaron Patterson 89d89fa49d When reading from stdin, put a wrapper around the IO object ... The purpose of this commit is to fix Bug #21188. We need to detect when stdin has run in to an EOF case. Unfortunately we can't _call_ the eof function on IO because it will block. Here is a short script to demonstrate the issue: ```ruby x = STDIN.gets puts x puts x.eof? ``` If you run the script, then type some characters (but _NOT_ a newline), then hit Ctrl-D twice, it will print the input string. Unfortunately, calling `eof?` will try to read from STDIN again causing us to need a 3rd Ctrl-D to exit the program. Before introducing the EOF callback to Prism, the input loop looked kind of like this: ```ruby loop do str = STDIN.gets process(str) if str.nil? p :DONE end end ``` Which required 3 Ctrl-D to exit. If we naively changed it to something like this: ```ruby loop do str = STDIN.gets process(str) if STDIN.eof? p :DONE end end ``` It would still require 3 Ctrl-D because `eof?` would block. In this patch, we're wrapping the IO object, checking the buffer for a newline and length, and then using that to simulate a non-blocking eof? method. This commit wraps STDIN and emulates a non-blocking `eof` function. [Bug #21188]		2025-08-04 12:34:33 -07:00
