NAME

tp-magic-config -- Helps creating 'Magic' tool plugins for Tux Paint(1)

SYNOPSYS

tp-magic-config [--apiversion | --version | --cflags | --pluginprefix | --plugindocprefix
| --dataprefix | --localpluginprefix | --localdataprefix]

DESCRIPTION

tp-magic-config is a simple shell script that responds with various pieces of information
about the currently-installed version of Tux Paint(1) that are useful when building
'Magic' tool plugins.

OPTIONS

--apiversion
Outputs the version of the Tux Paint 'Magic' tool plugin API that the installed
copy of Tux Paint supports. (For API compatibility testing.)

--version
Outputs the version of Tux Paint that tp-magic-config corresponds to.

--cflags
Outputs the compiler flags that Tux Paint 'Magic' tool plugins should be compiled
with. (For example, a "-I" include path option that tells the compiler where it
can find the plugin API header file, "tp_magic_config.h", that plugins must
#include.)

--pluginprefix
Outputs the system directory where the installed copy of Tux Paint expects to find
'Magic' tool plugins (".so" shared objects). (e.g.,
"/usr/share/tuxpaint/plugins")

--localpluginprefix
Outputs the user directory where the installed copy of Tux Paint expects to find
'Magic' tool plugins (".so" shared objects). (e.g.,
"/home/username/.tuxpaint/plugins")

--plugindocprefix
Outputs the directory where the installed copy of Tux Paint expects to find
documentation for 'Magic' tool plugins (".html" and ".txt" files). Tux Paint's
main documentation includes a link to this directory under the section on "Magic"
tools.

--dataprefix
Outputs the system directory where the installed copy of Tux Paint keeps its
global data files (e.g., "/usr/share/tuxpaint/"). This is the same value that
plugins installed system-wide will receive in the "data_directory" string within
the "magic_api" structure sent to the plugins' functions.

--localdataprefix
Outputs the user directory where the installed copy of Tux Paint expects plugins
to install their local data files. (e.g.,
"/home/username/.tuxpaint/plugins/data"). This is the same value that plugins
installed locally will receive in the "data_directory" string within the
"magic_api" structure sent to the plugins' functions.
