This fixes a segfault that occurs for the following reason: - In XKeyboard::initializeXkb(), the XkbSymbolParser::parse() is called with three arguments - string to process (symName), vector to push symbol names to (_symbolNames) and vector to push variant names to (_variantNames). - In XkbSymbolParser::parse(), it looks for char '+' in symName string, but Xkb may use '_' instead when creating that string. If the char is not found, parse() doesn't append anything to vectors and they remain empty. - Later, XKeyboard::initializeXkb() tries to access nonexistent data in _symbolNames, which causes a segmentation fault (on lines 162-163). |

Description
xkblayout-state is a small command-line program to get/set the current XKB keyboard layout.
It's a thin wrapper around a slightly version of Jay Bromley's XKeyboard class, the original of which is included in http://members.dslextreme.com/users/jbromley/files/ruby-xkb.tar.bz2.
Compilation and installation
- To compile just say:
make
- To install copy the resulting executable
xkblayout-state
somewhere in your path
Usage
xkblayout-state can be used to either print keyboard layout information on stdout or set the currently active layout.
Printing keyboard layout information
The command to print keyboard layout information is
xkblayout-state print format
format is printed to stdout with the following substitutions (to include a literal % use %%
):
%c
-> The number of the currently active layout%n
-> The name of the currently active layout%s
-> The symbol of the currently active layout%v
-> The variant of the currently active layout (this is empty if no variant is specified)%e
-> The variant of the currently active layout (this is the same as%s
if no variant is specified)%C
-> The number of defined layouts%N
-> A list containing the names of the layouts (one per line)%S
-> A list containing the symbols of the layouts (one per line)%V
-> A list containing the variants of the layouts (one per line; an empty line if no variant is specified for the respective layout)%E
-> A list containing the variants of the layouts (one per line; if no variant is specified for the respective symbol, the layout symbol is used)
Setting the active keyboard layout
The command to set the currently active keyboard layout is
xkblayout-state set [+-]number
number is the number of the layout to activate. It corresponds to the layouts in the order they appear in, for example, xkblayout-state print %N
, starting from zero. If number begins with a plus or minus sign, the number'th layout counting from the currently active layout down or up the list is activated. It wraps around if the list is exceeded.
