Description SOUMENDRA GANGULY 2020-07-30 19:33:51 UTC
Created attachment 216889 [details] script.diff The current manpage of script(1) says "Certain interactive commands, such as vi(1), create garbage in the type- script file. The script utility works best with commands that do not ma- nipulate the screen. The results are meant to emulate a hardcopy termi- nal, not an addressable one." This patch fixes this issue by appropriately calling cfmakeraw. Additional note: script(1) is currently able to record [-r] curses sessions perfectly; only the playback functionality [-p] needs to be fixed. To reproduce the problem, one may use the following program. https://github.com/iiSeymour/game-of-life by GitHub user iiSeymour, which, in the words of the author, is "a python implementation of Conway's Game of Life using the curses module with a small evolutionary twist." This script was written for Linux; therefore, one must call "python gol.py" on FreeBSD to bypass the #!

Additional notes: . This patch is a duplicate of that submitted by me as a part of https://github.com/freebsd/freebsd/pull/433. This was done to maximize the chances of getting noticed. If this patch on Bugzilla is accepted, I will close the GitHub pull request, and vice versa. . I submitted a similar patch for "scriptreplay(1)" from util-linux; it has now been merged by the maintainer of the project.
