Arch Linux User Repository

For some reason the PKGBUILD tries to extract the .jar-file with bsdtar and fails. It seems to ignore the noextract line.
I fixed that by replacing the line

noextract=('Mars${_ver}.jar')

with

noextract=("Mars${_ver}.jar")

in the PKGBUILD.

Could someone please create a GTK version using java-swing-joxy-git? Perhaps repackage as mars-mips-gtk or perhaps build it into mars-mips as an option to load the GTK. I tried using java-swing-joxy-git while loading the jar and the gtk graphics (icons, etc.) wouldn't load until mouse over or some other redraw interaction.

It would be nice to be able to transmit commandline arguments to the MARS program.

Just one last remark: you can use Bash's parameter expansion to create the 4_4 part in the URL/file name:

pkgver=4.4
_ver=${pkgver%.*}_${pkgver#*.}

Now ${_ver} will contain 4_4

I retract the part about noextract: the license file is inside the .jar file, so you should extract it anyway to obtain it.

A few other improvements should (or could) be made:
- as this package contains no ELF executables, 'arch' should be set to 'any';
- you could add a noextract value to prevent extracting of the .jar-file (which you don't need);
- according to the Java Package Guidelines [1], .jar-files should be installed in /usr/share/java/${pkgname}/ instead of in /opt;
- only the shell script should be installed as executable, the other files should be installed with permissions 644;
- you should add 'exec' (without the quotes) before and "$@" (including the double quotes) after the command line in the mars-mips shell script to feed the command line parameters to the Java program (also see the Java Package Guidelines);
- as there is an icon installed in /usr/share/icons/hicolor you should call gtk-update-icon-cache in an .install file and add gtk-update-icon-cache as a dependency (see GNOME Package Guidelines [2]);
- somehow, the MIT license is not a common license included in the licenses package; therefore you should include it within /usr/share/licenses/${pkgname}/

Please quote all instances of $pkgdir en $srcdir to allow for spaces in directory names.

If possible, a launcher under applications>programming would be nice.
