After this update, octave-gui (5.2.0) in x-window shows strange string at the prompt. >> undecodable token: \001b(hex)[?2004l undecodable token: \001b(hex)[?2004h To reproduce this, 1) Start X with 'run XWin -multiwindow' 2) Start octave-gui with 'env DISPLAY=:0 octave --force-gui' Does libreadline7 (8.1) break compatibility with old one? Reverting libreadline7 to 7.0.3-3 solves the issue. Setting set enable-bracketed-paste off in ~/.inputrc also solves the problem. This may be a problem of octave side. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=975902 https://www.mail-archive.com/bug-readline@gnu.org/msg01416.html Any idea? -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
