regtool 2.11.1 need a way to specify leading "-" in values

regtool 2.11.1 need a way to specify leading "-" in values

[Gordon Grimes]

I believe there is no way to specify values with leading "-" in regtool.  I expect the same applies to keys.  An "end of switch processing" switch would be useful, forcing 'regtool' to interpret all remaining arguments literally.

Example:
% regtool -s set '\HKCU\Environment\MAVEN_OPTS' "-Xms512m -Xmx3072m  -Dcom.sun.management.jmxremote"
regtool: unknown option -- X
Try `regtool --help' for more information.


% regtool --version
regtool (cygwin) 2.11.1

Fortunately, you are mistaken.  regtool uses getopt_long(), and
therefore, like all other programs that use this, automatically inherits
the POSIX rule that '--' is the marker for "end of switch processing".

Try:

regtool -s set '\HKCU\Environment\MAVEN_OPS' -- "-Xms512m -Xmx3072m
-Dcom.sun.management.jmxremote"

Try:

regtool -s set '\HKCU\Environment\MAVEN_OPS' -- "-Xms512m -Xmx3072m -Dcom.sun.management.jmxremote"
