Most likely what is happening is that the two Python instances you are using are linked to different versions of the external readline library. From the version information, it's clear that you are using the Python 3.8.0 from the python.org macOS installer. That Python uses the macOS-supplied BSD editline (AKA libedit) for readline functionality. The Python 3.7.3 you have is not from python.org and based on the prompt it looks like it was linked with a version of GNU readline which probably does bind ^R to the reverse search function by default. As described in the Python Library Reference page for readline (https://docs.python.org/3/library/readline.html), both GNU readline and BSD editline can be tailored via configuration files; GNU readline uses ~/.inputrc while BSD editline uses ~/.editrc. On macOS, the available configuration commands for editline are described in the man page for editrc: man 5 editrc In particular, you should be able to enable editline's reverse search functionality by adding the following line to ~/.editrc: bind ^R em-inc-search-prev where ^R is two characters, not the single character CTRL-R. ---------- nosy: +ned.deily resolution: -> third party stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38995> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
