I'm using Cygwin for two reasons: mintty + Emacs w32. Nowadays WSL 1 has become important (vendors provide ready to work .deb packages, I use: Ansible + Google Cloud SDK, if name any). Still WSL 1 lacks UI and integrates less smoothly into my workflow to replace Cygwin's amazing Emacs W32. WSL1 files are "hidden" for regular access. Emacs has TRAMP mode to access foreign environments: https://www.gnu.org/software/tramp/ I tried to define configuration that should have allowed to access WSL 1 from Cygwin's Emacs via "wsl sh" jump (the way TRAMP support "su" & "sudo" jumps): * https://www.reddit.com/r/emacs/comments/jrkgmy/tramp_for_wsl_1_from_cygwin_emacsw32/ * https://github.com/microsoft/WSL/issues/6236 - wsl.exe periodically sends control characters making impossible "piping" via interactive/terminal mode The problem is that when Cygwin's Emacs invokes "wsl.exe" conhost or wsl?? thinks it is in a PTY mode and sends different "clearing" terminal escape sequences (see WSL issue report). I reproduce garbage with Elisp code: (setq xxx (make-process :name "xxx" :buffer "xxx" :command '("wsl" "echo" "OK") :connection-type 'pty)) (stop-process xxx) Note that changing the last argument "pty" => "pipe" solves the problem, but things are a bit complicated... TRAMP mode has been implemented via call to "sh" by internal API "make-process". And then TRAMP sends "wsl ..." to the shell so WSL thinks it is in PTY and I have no way to influence that decision (( I tried stupid tricks like passing everything related to "ws.exe" via pipe to "cat": (with-eval-after-load 'tramp (setf (alist-get "wsl" tramp-methods nil nil #'equal) '((tramp-login-program "sh") (tramp-login-args (("-c") ("wsl") ("-u" "%u") ("-d" "%h") ("|" "cat"))) (tramp-remote-shell "/bin/sh") (tramp-remote-shell-login ("-l")) (tramp-remote-shell-args ("-c")) (tramp-connection-timeout 10) (tramp-session-timeout 300)))) or define a wrapper script that has "wsl ... | cat" inside. Nothing helped. Few experiments with Cygwin's Expect also failed as I forgot everything about that obscure tech... So I need to write some wrapper that will bidirectionally pipe to "wsl.exe" putting wsl into piped instead TTY mode. It can be that there is a ready solution. If not please advise which API should I use to write such a wrapper. Should it be Cygwin's pipe/dup2/fork/execvp or popen? Or should it be Windows native CreateChildProcess / WriteToPipe / ReadFromPipe as here: https://docs.microsoft.com/en-us/windows/win32/procthread/creating-a-child-process-with-redirected-input-and-output Please CC me in replies, I'll check the mail archive after a week to not lose any responses. -- 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
