* Add debug information.
* This change fixed a bug where the new winpty-agent.exe process
successfully started, but immediately exited without reaching main().
The bug occurred while SSH'ing into the Cygwin SSH server.
* If a new window station can't be created, keep going anyway. I *think*
this is what IntelliJ's fork is doing. Perhaps the window should be
marked SW_HIDE in this case?
* Rename WINPYDBG to WINPTY_DEBUG.
* Add an environment variable WINPTY_SHOW_CONSOLE. If non-empty, the
console window is placed on the same window station and is visible.
It's intended for testing purposes.
If a process is running under control of winpty, the output of the process is decorated with ESC sequences to control a terminal to print the process output nicely. In some environments however, the client showing the output to the user is not a full terminal emulation, the Eclipse CDT debug console view in example, and the ESC sequences are printed as output additional to the real process output. This commit is adding an API function to switch into a mode where winpty is not decorating the process output with ESC sequences. The console mode is designated to pass on the process output to the client as is.
Added new agent message "GetProcessId" and a API "winpty_get_process_id"
to allow access to the process id of the started process. The process id
is needed to integrate "winpty" with Eclipse CDT to launch native Windows
console applications inside the Eclipse UI.
If I run a GUI program inside mintty using winpty, the GUI's window should
appear on the same desktop as mintty, not on the hidden desktop containing
the winpty console.
Even though STARTUPINFO.lpDesktop's type is LPTSTR (instead of LPCTSTR),
the documentation doesn't say anything about CreateProcess modifying the
lpDesktop string, so I didn't bother making a copy of desktop.c_str().
* This avoids a name conflict with an existing unrelated project.
* I think winpty is a better name anyway. (i) It's more obviously
Windows-related. (ii) I think it more accurately describes what it
does. A "pseudo-console" ought to mirror the console API and allow
replacing the implementation built-in to Windows. This project is only
trying to provide functionality similar to using the master interface of
a Unix pty, but for native console programs.
