Issue #21188 has been updated by k0kubun (Takashi Kokubun). Backport changed from 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONTNEED, 3.4: REQUIRED to 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONTNEED, 3.4: DONE ruby_3_4 commit:1f421d092bb8c290df5cfc9e95a01e279ebadc42. ---------------------------------------- Bug #21188: PRISM does not end reading from tty with ^D twice https://bugs.ruby-lang.org/issues/21188#change-114618 * Author: nobu (Nobuyoshi Nakada) * Status: Closed * Assignee: prism * Backport: 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONTNEED, 3.4: DONE ---------------------------------------- When reading from tty, `^D` ends the text without the newline. ```console $ cat a ``` Typing `^D` here, only "a" is sent without a newline, and `cat` echos back it. Then by typing `^D` again, an empty read that means EOF causes `cat` to exit. `ruby --parser=parse.y` behaves in this manner: ```console $ ruby --parser=parse.y p __FILE__"-" ``` Typing `^D` twice just after `__FILE__`, and `p` prints `"-"`. However prism requires `^D` thrice. -- https://bugs.ruby-lang.org/
