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=
              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 gir's are located in XDG_DATA_DIRS/share/gir-1.0. It
              is normally set on a distribution so you shouldn't need to set
              it yourself.
