Extra arguments for /usr/bin/josm

[Crashillo]

According to https://josm.openstreetmap.de/wiki/Help/Preferences#Settingacommondirectory you can set a different directory to handle the ​https://wiki.openstreetmap.org/wiki/Import/Guidelines#Use_a_dedicated_user_account with a single line:

java -Djosm.home=JOSM-imports -jar josm.jar

Since unix wraps all the java stuff with the /usr/bin/josm launcher, you may think that the following code should work, but:

$ josm -Djosm.home=JOSM-imports
Using /usr/lib/jvm/java-11-openjdk-amd64/bin/java to execute josm.
JOSM: unrecognized option '-Djosm.home'

I figured out that https://josm.openstreetmap.de/browser/josm/trunk/native/linux/tested/usr/bin/josm#L71 is the responsible for. But you can make it work just switching the "extra arguments" position like this:

- $JAVACMD $JAVA_OPTS -jar /usr/share/josm/josm.jar "$@"
+ $JAVACMD $JAVA_OPTS "$@" -jar /usr/share/josm/josm.jar

Is there any issue about switching the "$@" position that I'm missing? IMO, that would simplify the things a lot, keeping the java stuff wrapped.

Thanks in advance

Well. This change makes it impossible to pass any option to josm:

java --language=en -jar josm-custom.jar

Unrecognized option: --language=en

If you want to add custom java arguments I suggest to use another wrapper, e.g. stored in your $HOME/bin dir.

I achieved an easier solution which doesn't envolve any extra wrapper, based on the .desktop unix files:

Duplicate the file /usr/share/applications/org.openstreetmap.josm.desktop and modify only these fields as follows:

[Desktop Entry]
...
Name=JOSM Imports
Exec=env JAVA_OPTS="-Djosm.home=JOSM-imports" josm %U
...

Just simple as that 🎉

To make it work in the terminal you need this wrapper for /usr/bin/josm e.g. /usr/local/bin/josm-imports or $HOME/bin/josm-imports as @stoecker wrote.
