Typelib decompiler


gi-decompile-typelib [OPTION…] TYPELIB [TYPELIB…]


gi-decompile-typelib is a GIR decompiler, using the repository API. It generates GIR XML files from the compiled binary typelib format. The output will be written to standard output unless the --output is specified.

The binary typelib format stores a subset of the information available in GIR XML, so not all typelibs can be decompiled in this way, and the resulting GIR XML might be incomplete.

Normally, GIR XML should be generated from source code, headers and shared libraries using g-ir-scanner(1) instead of using this tool.



Show help options.


Save the resulting output in FILENAME.

--includedir DIRECTORY

Add DIRECTORY to the search path for typelibs. This option can be used more than once. The first DIRECTORY on the command-line will be searched first (highest precedence).


Show all available information.


Show program’s version number and exit.



$ libdir=/usr/lib/x86_64-linux-gnu     # or /usr/lib64 or similar $ gi-decompile-typelib -o Gio-2.0.gir

System Message: ERROR/3 (../docs/reference/girepository/gi-decompile-typelib.rst:, line 84)

Unexpected indentation.


$ diff -u /usr/share/gir-1.0/Gio-2.0.gir Gio-2.0.gir

You will see that the original GIR XML contains much more information than the decompiled typelib.
