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.

       --strict
              Display warnings for strict introspectable API.

       --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.

       --c-include=C_INCLUDES
              Headers which should be included in  C  programs.  This  option  can  be  specified
              multiple times to include more than one header.

       -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.

       --compiler=COMPILER
              The  C  compiler  to  be used internally by g-ir-scanner when introspecting the run
              time  type  information,  like  properties,  signals,  ancestors,  and  implemented
              interfaces. It has the same semantics as the CC environment variable.

       --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.

       The variable GI_SCANNER_DEBUG can be used to debug issues in the build-system that involve
       g-ir-scanner.  When  it  is set to save-temps, then g-ir-scanner will not remove temporary
       files and directories after it terminates.

       The variable GI_HOST_OS can be used to control the OS name  on  the  host  that  runs  the
       scanner. It has the same semantics as the Python os.name property.

       The  variable  GI_CROSS_LAUNCHER  can  be  used  to  wrap  the  GType introspection binary
       generated by g-ir-scanner before executing it. It is useful when generating  introspection
       data in a cross-compilation environment.
