View file @ 7960c687
included in LibVNCServer package, autoconf'ed it
SetXCutText implemented
fix for cargs
attributes work.
cursor in LinuxVNC is shown.
paste works
selection works (no cursor trails)
LinuxVNC gets it's dimensions via ioctl TIOCGWINSZ
First working key injection in LinuxVNC!
Added Mouse marking
added screenBuffer (so you have ASCII screen also)
fixed CopyRect for scrolling (need to propagate to libvncserver)
made VNCommand work (no prompt for bash, but else seems ok)
added flag for VNCommand to send input only after a newline
(good for interactive bash)

In this stage (beta), there are two programs functional:
LinuxVNC <tty number>
monitor a virtual console (text mode) of Linux. You need
root privileges, or at least be in the "tty" group, because
it reads /dev/vcsN and writes /dev/ttyN.
It follows the same idea as WinVNC, x11vnc or OSXvnc, i.e. it
takes an existing desktop and exports it via RFB (VNC), just that
LinuxVNC exports text.
VNCommand <command> <args>
executes <command> redirecting stdin from a vncviewer and stdout &
stderr to the vnc clients. This might be renamed to vncTerm if
there are some term capabilities added (up to now, bash doesn't look
nice). Colours and other ANSI sequences need to be added.
My original plan was to create a program named vncTerm. It was meant to
overcome incompatibilities between different TERMs, but I found "screen" to
be just such a program. Maybe once some time in the future I'll make a
patch for screen to use VNConsole to export it's contents via RFB...
These two programs are a simple application of LibVNCServer with a small
console layer in between (VNConsole). You can use them under the terms
(not vncTerms ;-) of the GPL. They where written by Johannes E. Schindelin.

VNConsole:
LinuxVNC:
VNCommand:
make Control or Alt sequences work.
Find out how to satisfy isatty(). => /dev/ptyN
Fix check if child is alive.
Add command line option for real interactive mode.
done:
.treat colours correctly (use /dev/vcsaN's attributes).
.introduce per cell colours (for attributes)
.fix cursor fuckup when selecting.
.default to paste for right mouse button.
.have an idea how to insert keys
.convert VNCommand to an interactive shell (vncTerm)
.bidirectional pipes (spawn a shell ...)
.mark with mouse (copy text)
.when scrolling, cursor must be hidden!
modifiedRegion which are copied with CopyRect have to be modified also.
