Feature request: Add support for multiple or multiline "custom"

[noabody]

We can work around the Keywords issue from #20 with --custom but there doesn't seem to be a way to use multiple. Only the last is honored, and it isn't possible to inject \n to break the line into multiple parts.

Neither of these produce StartupWMClass and Keywords:

gendesk -f -n --name=name --comment='comment' --genericname='comment' --custom='StartupWMClass=class' --custom='Keywords=this;that;' --exec=exec --icon=icon --terminal=false --categories='This;That' --startupnotify=false --pkgname=name

gendesk -f -n --name=name --comment='comment' --genericname='comment' --custom='StartupWMClass=class\nKeywords=this;that;' --exec=exec --icon=icon --terminal=false --categories='This;That' --startupnotify=false --pkgname=name

Thanks for reporting! Supporting multiple custom lines might be a good idea.

I guess there is a crossover point where enough custom lines means that the contents should be piped directly to the .desktop file instead.

And StartupWM could have a dedicated flag.

There are many possible paths.

I agree. Looking at the specs, there are 24 recognized keys that can reside within the desktop file. Currently, gendesk supports 12 and one custom.

I believe the most common ones should be implemented, without question. Having multiple, or a multi-line, custom should be adequate for those remaining.

I agree.
