DESCRIPTION

       gtk4-builder-tool can perform various operations on GtkBuilder UI definition files.

COMMANDS

   Validation
       The validate command validates the given UI definition file and reports errors to stderr.

       Note  that there are limitations to the validation that can be done for templates, since they are closely
       tied to the class_init function they are used in.  If your UI file uses types from third-party libraries,
       it may help to add those libraries to the LD_PRELOAD environment variable.

       --deprecations
          Warn about uses of deprecated types in the UI definition file.

   Enumeration
       The enumerate command prints all the named objects that are present in the UI definition file.

       --callbacks
          Print the names of callbacks as well.

   Preview
       The preview command displays the UI definition file.

       This command accepts options to specify the ID of the toplevel object and a CSS file to use.

       --id=ID
          The ID of the object to preview. If not specified, gtk4-builder-tool will choose a suitable object  on
          its own.

       --css=FILE
          Load style information from the given CSS file.

   Render
       The  render  command saves a rendering of the UI definition file as a png image or node file. The name of
       the file to write can be specified as a second FILE argument.

       This command accepts options to specify the ID of the toplevel object and a CSS file to use.

       --id=ID
          The ID of the object to preview. If not specified, gtk4-builder-tool will choose a suitable object  on
          its own.

       --css=FILE
          Load style information from the given CSS file.

       --node
          Write a serialized node file instead of a png image.

       --force
          Overwrite an existing file.

   Screenshot
       The screenshot command is an alias for render.

   Simplification
       The  simplify  command  simplifies  the  UI  definition file by removing properties that are set to their
       default values and writes the resulting XML to the standard output, or back to the input file.

       When the --3to4 option is specified, the simplify command interprets the input as a GTK 3 UI  definuition
       file  and  attempts to convert it to GTK 4 equivalents. It performs various conversions, such as renaming
       properties, translating child properties to layout  properties,  rewriting  the  setup  for  GtkNotebook,
       GtkStack, GtkAssistant  or changing toolbars into boxes.

       You  should  always test the modified UI definition files produced by gtk4-builder-tool before using them
       in production.

       Note in particular that the conversion done with --3to4 is meant as a starting point for a port from  GTK
       3 to GTK 4. It is expected that you will have to do manual fixups  after the initial conversion.

       --replace
          Write the content back to the UI definition file instead of using the standard output.

       --3to4
          Transform a GTK 3 UI definition file to the equivalent GTK 4 definitions.

                                                                                             GTK4-BUILDER-TOOL()
