Patch Utility - RetroGuard Documentation
A utility called RGpatch has been provided
to automate this patch generation. The extraction of updated classes and resource files from the obfuscated
Jar and the creation of the patch Jar could, in theory, be done by hand.
Starting with
a list of the classes and resources to be included in the patch, you would
convert these names to their obfuscated form by referring to the log-file,
then extract the obfuscated files from the full Jar and repack them into
a small patch Jar.
This procedure would be tiresome and error-prone, particularly on the Windows
operating systems due to the limitations of the file system (Java identifiers
are case-sensitive, but the Windows OSes smash case, which can lead to one
class overwriting another during the un-jar/re-jar process).
The command for running RGpatch has the form,
java RGpatch WHOLE-JAR PATCH-JAR LOGFILE LISTFILE
where:
WHOLE-JAR is the filename for the complete,
incrementally obfuscated Jar file
PATCH-JAR is the filename that will be used for the
generated patch Jar file
LOGFILE is the filename of the log output during the
obfuscation of WHOLE-JAR
LISTFILE is the filename of a text file containing
a list of the unobfuscated names of class and resource files which are to
be included in the patch Jar.
There are no optional arguments for this command.
If WHOLE-JAR, LOGFILE or
LISTFILE cannot be read, or if
PATCH-JAR cannot be written, execution is terminated
with a warning message.
