… plug-in code.
In particular, we should not hardcode this in core code anymore. The
behavior is otherwise exactly the same, except that we made the core
code generic as it should be.
The CLI options now know which procedures are batch procedures or not.
First it means that it won't just randomly try any procedure name one
may pass and will properly output an error if you pass a non-existing
interpreter procedure.
Secondly, there is no default interpreter anymore (unless only one
interpreter exists). If you don't set an interpreter procedure with
--batch-interpreter or if you pass a wrong one, it will output the list
of available batch procedure, thus helping you understanding how to use
the --batch option.
If you call GIMP with batch commands and ask it to quit immediately, you
are likely interested by failure information. For this reason, let's now
report exit code other than success, but only in such case. In
particular, even if the batch commands fail, but GIMP is not set to exit
immediately, we continue reporting SUCCESS run at the very end (when
exiting interactively).
Note that I hardcode a few exit values, as standardly found on Linux
(but not using headers which may not be found on all platforms; in
particular, Windows apparently doesn't use any standard code other than
0 for success, from what my searches return).
Additionally, when several commands are requested, GIMP will now stop at
the first failing and will return its error code, and print a message on
stderr to easily report the failed command for easier debugging.
- Change the wire protocol's GPProcInstall to transmit the entire
information needed for constructing all GParamSpecs we use, don't
use GimpPDBArgType in GPProcInstall but an enum private to the wire
protocol plus the GParamSpec's GType name. Bump the wire protocol
version.
- Add gimpgpparamspecs.[ch] in both app/plug-in/ and libgimp/ which
take care of converting between GPParamDef and GParamSpec. They
share code as far as possible.
- Change pluginrc writing and parsing to re-use GPParamDef and the
utility functions from gimpgpparamspecs.
- Remove gimp_pdb_compat_param_spec() from app/pdb/gimp-pdb-compat.[ch],
the entire core uses proper GParamSpecs from the wire protocol now,
the whole file will follow down the drain once we use a GValue
representation on the wire too.
- In gimp_plug_in_handle_proc_install(), change the "run-mode"
parameter to a GParamSpecEnum(GIMP_TYPE_RUN_MODE) (if it is not
already an enum). and change all places in app/ to treat it as an
enum value.
- plug-ins: fix cml-explorer to register correctly, a typo in
"run-mode" was never noticed until now.
- Add gimpgpcompat.[ch] in libgimp to deal with all the transforms
between old-style wire communication and using GParamSpec and
GValue, it contains some functions that are subject to change or
even removal in the next steps.
- Change the libgimp GimpProcedure and GimpPlugIn in many ways to be
able to actually install procedures the new way.
- plug-ins: change goat-exercise to completely use the new GimpPlugIn
and GimpProcedure API, look here to see how plug-ins will look in
the future, of course subject to change until this is finished.
- Next: changing GPParam to transmit all information about a GValue.
