Of course I understood your article, and as I say, it's pretty naive.
First thing is what knipknap points out: how are you going to tackle
parameter-ignoring script someone placed in your path that does "rm -rf
~/"? Second thing is, you ignore completely more complex activation
scenarios, like network-based ones, and influencing already running
application -- support for that from command line means turning _every_
app into "unique app" instance, and coming up with sketchy ad-hoc IPC
mechanism anyway. Thank you very much, I'll pass.

mathrick at megumi:~$ gimp --parameter-list
Invalid option "--parameter-list"
GIMP version 2.0.3
Usage: gimp [option ... ] [file ... ]
I don't see it being used in "existing but still used tools"
Adding support for it means:
1) Work of coming up with sensible and well-covered spec for it
2) Work of documenting every option
3) Work of restructuring apps' internals into interfaces supporting it
4) Work of testing it in real life
5) Work of fighting with old, non-conformant apps (remember rm -rf ~/ ?)
I can't see how it's better or easier than adding proper support for
something that's actually designed for that purpose.

And? Do you think it's only a matter of extending --help? For small
hacks, sure, but for any reasonable coverage, it's 5 points above, and
it's still essentially a hack after all the work.

DBUS interfaces are pretty much self-documenting, when it comes to
listing supported methods and parameters. And real documentation still
needs to be written, and can't be autogenerated.

Can you tell me, what is the basis of your statements here? Why do you
think Evt _has to_ be limited, GNOME-only, or terminal unfriendly, or
that it can't provide friendly dialogs? And your almost-HIG is bullshit
anyway, starting with "help" and "version" parameters as the very first
ones listed in your "HIGgish" dialog.

Pffft, again the same naive thinking. _Printing_ text dump is easy, I
can hack up script that does that for DBUS interfaces right _now_. What
is hard is making it do something _useful_.
