NAME

       g-ir-scanner - extracting C metadata from sources and headers

SYNOPSIS

       g-ir-scanner [OPTION...] FILES...

DESCRIPTION

       g-ir-scanner  is  a tool which generates GIR XML files by parsing headers and introspecting GObject based
       libraries.  It is usually invoked during the normal build step for a project and the information is saved
       to  disk  and later installed, so that language bindings and other applications can use it.  Header files
       and source files are passed in as arguments on the command line.  The suffix determines whether a file be
       treated  as  a  source file (.c) or a header file (.h). Currently only C based libraries are supported by
       the scanner.

OPTIONS

       --help Show help options

       --quiet
              If passed, do not print details of normal operation.

       --warn-all
              Display warnings for public API which is not introspectable.

       --warn-error
              Make warnings be fatal errors.

       --format=FORMAT
              This parameters decides which the resulting format will be used.  The default value is gir.

       --include=NAME
              Add the specified introspection dependency  to  the  scanned  namespace.   NAME  is  of  the  form
              NAMESPACE-VERSION, like Gtk-3.0.

       --include-uninstalled=PATH
              Add  the specified introspection dependency to the scanned namespace.  This differs from --include
              in that it takes a file path, and does not process the pkg-config dependencies (since they may not
              be installed yet).

       --add-include-path=PATH
              Add  a directory to the path which the scanner uses to find GIR files.  Can be used multiple times
              to specify multiple directories

       -i, --library=LIBRARY
              Specifies a library that will be introspected. This means that the *_get_type()  functions  in  it
              will be called for GObject data types.  The name of the library should not contain the leading lib
              prefix nor the ending shared library suffix.

       -L, --library-path=PATH
              Include this directory when searching for a library.  This option can be specified multiple  times
              to include more than one directory to look for libraries in.

       -Idirectory
              Include  this  directory  in the list of directories to be searched for header files.  You need to
              pass to the scanner all the directories you'd  normally  pass  to  the  compiler  when  using  the
              specified source files.

       -n, --namespace=NAME
              The  namespace  name.  This  name should be capitalized, eg the first letter should be upper case.
              Examples: Gtk, Clutter, WebKit.

       --no-libtool
              Disable usage of libtool for compiling stub introspection binary.  Use this if your  build  system
              does not require libtool.

       --libtool
              Full path to libtool executable.  Typically used for Automake systems.

       --nsversion=VERSION
              The  namespace  version.  For instance 1.0. This is usually the platform version, eg 2.0 for Gtk+,
              not 2.12.7.

       -p, --program=PROGRAM
              Specifies a binary that will be introspected. This means that the  *_get_type()  functions  in  it
              will  be  called for GObject data types.  The binary must be modified to take a --introspect-dump=
              option, and to pass the argument to this function to g_irepository_dump.

       --program-arg=ARG
              Additional argument to pass to program for introspection.

       --identifier-prefix=PREFIX
              This option may be specified multiple times.  Each one gives a prefix that will be  stripped  from
              all  C  identifiers.   If none specified, the namespace will be used.  Eg, an identifier prefix of
              Foo will export the identifier typdef struct _FooBar FooBar; as Foo.Bar.

       --symbol-prefix=PREFIX
              This option may be specified multiple times.  Each one gives a prefix that will be  stripped  from
              all  C  symbols.   Eg,  an  symbol  prefix  of  foo will export the symbol foo_bar_do_something as
              Foo.Bar.do_something.

       --accept-unprefixed
              If specified, the scanner will accept identifiers and symbols which do  not  match  the  namespace
              prefix.  Try to avoid using this if possible.

       --output=FILENAME
              Name of the file to output. Normally namespace + format extension.  Eg, GLib-2.0.gir.

       --pkg=PACKAGE
              List  of  pkg-config packages to get compiler and linker flags from.  This option can be specified
              multiple times to include flags from several pkg-config packages.

       --pkg-export=PACKAGE
              List of pkg-config packages that are provided by the generated gir.  This option can be  specified
              multiple  times  if the gir provides more packages.  If not specified, the packages specified with
              --pkg= will be used.

       --verbose
              Be verbose, include some debugging information.

       ENVIRONMENT VARIABLES
              The g-ir-scanner uses the XDG_DATA_DIRS variable to check  for  dirs,  the  girs  are  located  in
              XDG_DATA_DIRS/gir-1.0.  It  is  normally  set  on  a  distribution so you shouldn't need to set it
              yourself.

              The variable GI_SCANNER_DISABLE_CACHE ensures that the scanner will not write cache data to $HOME.
