This change adds a new way for fxconv to discover metadata for file
conversions. This complements the existing mechanism of passing
parameters on the command-line.
The new mechanism activates when fxconv is called without a type
argument. Type information and metadata are searched in an
fxconv-metadata.txt file in the same folder as the resource. The
metadata file lists parameters, with some additional flexibility enabled
by the use of wildcards.
This way of declaring will replace command-line argument passing, which
currently read parameters from the unreadable and not-so-maitainable
project.cfg file. Both the GNU make and CMake build systems should use
it in the future. The current way is still supported only for older
projects and one-shot conversions outside of projects.
Custom conversions can be used by:
* Providing a converters.py in the main directory with a convert()
function
* Specifying --custom on the fxconv command-line or using a subfolder or
assets-{fx,cg} unused by standard fxconv
This commit introduces the libimg image format, selected with the option
type:libimg-image. To avoid confusion with the bopti image format,
options -i and --image are now deprecated and should be replaced with
--bopti-image or type:bopti-image. The fxSDK Makefile has been updated
accordingly.
To support the construction of a structure that contains a pointer in
fxconv, an assembly-code feature has been added. The structure itself is
assembled with as and then linked with the data proper. This allows the
structure to reference the data by name and have the pointer calculated
by ld at link time.
This change enhances the style of fxconv by using more classes and
generally more Pythonic constructions.
It also introduces image conversion for fx-CG 50, requiring the use
of --fx or --cg to specify the target machine with -i. The default
is set to --fx to maintain compatibility with older Makefiles.
