Replaces the hardcoded nxagent keybindings by a configurable table of keybindings. The default configuration is the same as the original one, to maintain compatibility. A user/administrator can either specify a command line parameter, environment variable or place a file in ~/.nx/config/keystroke.cfg or /etc/nx/keystroke.cfg to reconfigure these keybindings. The configuration file format is XML, a dependency on libxml2 is added to allow parsing the configuration. --- nx-X11/programs/Xserver/Imakefile | 9 +- nx-X11/programs/Xserver/hw/nxagent/Imakefile | 9 +- nx-X11/programs/Xserver/hw/nxagent/Keystroke.c | 699 ++++++++++++++++-------- nx-X11/programs/Xserver/hw/nxagent/Keystroke.h | 47 ++ 4 files changed, 527 insertions(+), 237 deletions(-) diff --git a/nx-X11/programs/Xserver/Imakefile b/nx-X11/programs/Xserver/Imakefile index 3f53eca..80e3a71 100644 --- a/nx-X11/programs/Xserver/Imakefile +++ b/nx-X11/programs/Xserver/Imakefile @@ -1013,15 +1013,18 @@ $(NXAGENTOBJS) $(NXAGENTLIBS) $(NXAGENTSYSLIBS):: $(NXAGENTDIRS) #if defined(SunArchitecture) NXAGENTNXLIBS = -L ../../../nxcomp -L ../../../nxcompext -L ../../../nxcompshad \ -lXcomp -lXcompext -lXcompshad -lrt -L/usr/sfw/lib -lNX_Xrender -lNX_Xfixes \ - -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdamage -lNX_Xrandr -lNX_Xcomposite -lNX_Xdmcp + -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdamage -lNX_Xrandr -lNX_Xcomposite -lNX_Xdmcp \ + `pkg-config --libs libxml-2.0` #elif defined(cygwinArchitecture) NXAGENTNXLIBS = -L ../../../nxcomp -L ../../../nxcompext \ -lXcomp -lXcompext -lNX_Xrender -lNX_X11 -lNX_Xext -lNX_Xcomposite -lNX_Xfixes \ - -L ../../../nxcompshad -lXcompshad -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdmcp + -L ../../../nxcompshad -lXcompshad -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdmcp \ + `pkg-config --libs libxml-2.0` #else NXAGENTNXLIBS = -L ../../../nxcomp -L ../../../nxcompext -L ../../../nxcompshad \ -lXcomp -lXcompext -lXcompshad -lNX_Xrender -lNX_X11 -lNX_Xext -lNX_Xfixes \ - -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdamage -lNX_Xrandr -lNX_Xcomposite -lNX_Xinerama -lNX_Xdmcp + -L../../../nx-X11/exports/lib -lNX_Xtst -lNX_Xdamage -lNX_Xrandr -lNX_Xcomposite -lNX_Xinerama -lNX_Xdmcp \ + `pkg-config --libs libxml-2.0` #endif #endif diff --git a/nx-X11/programs/Xserver/hw/nxagent/Imakefile b/nx-X11/programs/Xserver/hw/nxagent/Imakefile index a8e1621..ccd53d1 100644 --- a/nx-X11/programs/Xserver/hw/nxagent/Imakefile +++ b/nx-X11/programs/Xserver/hw/nxagent/Imakefile @@ -142,7 +142,8 @@ INCLUDES = -I. -I../../../../../nxcomp -I../../../../../nxcompext -I../../../../ -I../../miext/damage -I../../miext/cw \ -I../../GL/glx -I../../GL/include -I../../../../lib/GL/include -I../../Xext \ -I$(EXTINCSRC) -I$(XINCLUDESRC) \ - $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) + $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) \ + `pkg-config --cflags-only-I libxml-2.0` #ifdef SunArchitecture INCLUDES = -I. -I../../../../../nxcomp -I../../../../../nxcompext -I../../../../../nxcompshad \ -I../../../../extras/Mesa/include \ @@ -152,7 +153,8 @@ INCLUDES = -I. -I../../../../../nxcomp -I../../../../../nxcompext -I../../../../ -I../../GL/glx -I../../GL/include -I../../../../lib/GL/include -I../../Xext \ -I../../miext/damage -I../../miext/cw \ -I$(EXTINCSRC) -I$(XINCLUDESRC) \ - $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) + $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) \ + `pkg-config --cflags-only-I libxml-2.0` #else #ifdef cygwinArchitecture INCLUDES = -I. -I$(XBUILDINCDIR) -I$(FONTINCSRC) \ @@ -162,7 +164,8 @@ INCLUDES = -I. -I$(XBUILDINCDIR) -I$(FONTINCSRC) \ -I../../../../../nxcomp -I../../../../../nxcompext -I../../../../../nxcompshad \ -I../../../../extras/Mesa/include \ -I$(EXTINCSRC) -I$(XINCLUDESRC) \ - $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) + $(VFBINCLUDES) $(NXFONTINCLUDES) $(LIBXRANDRINCLUDES) \ + `pkg-config --cflags-only-I libxml-2.0` #endif #endif diff --git a/nx-X11/programs/Xserver/hw/nxagent/Keystroke.c b/nx-X11/programs/Xserver/hw/nxagent/Keystroke.c index 6c6e477..b5f4acf 100644 --- a/nx-X11/programs/Xserver/hw/nxagent/Keystroke.c +++ b/nx-X11/programs/Xserver/hw/nxagent/Keystroke.c @@ -28,8 +28,15 @@ #include "Keystroke.h" #include "Drawable.h" +#include <unistd.h> + +#include <libxml/parser.h> +#include <libxml/tree.h> + extern Bool nxagentWMIsRunning;
