I'm catching on late to the removal of the command-line options from Rev 4.0
onwards.
Specifically, I have a current application which is sometimes run
interactively, but can also be run non-interactively from the command line.
To be clear about this, the commandline options have *not* disappeared
from post-3.5 LC. I have a commercial app that would have *very*
serious problems if this were so. That said, I haven't used the -ui
option in some time - I simply hide the stack on preOpenStack and I've
got a nice faceless app. Obviously you could pass a commandline option
to hide or not, which would let you run the app interactively if
desired.
Sorry, I misspoke: it's not that you can no longer run LC standalones in
command-line mode; but what has I believe gone is the ability to run without
attempting to create a graphic user interface, by invoking the app from the
command line with the -ui flag.
If I've just missed something, I'll be delighted, but as far as I can tell
this is the case.
I create a simple app which if it finds that the environment = "command line"
does some things and then quits.
If I build a standalone with this, using Rev 3.5, and launch it from the
command line:
- on Mac with no parameters it opens in the normal way, and I can interact
with it and quit it using the default menu.
- on Mac with -ui nothing appears in the dock or on the screen, it does the
requested task and quits.
- on a headless Linux box with no parameters I get the message "Can't open
display"
- on a headless Linux box with -ui it does the requested task and quits.
If I build the same app using LC 4.6.4
- on Mac with no parameters it opens in the normal way, and I can interact
with it and quit it using the default menu.
- on Mac with -ui the icon bounces in the dock for a long time, and then
sticks there; there is no sign of the app working, and it has to be force quit.
- on a headless Linux box with no parameters I get the message "Can't open
display"
- on a headless Linux box with -ui it hangs.
So it would be incorrect to say that the -ui flag has no effect on a
standalone built with LC 4.6.4; but it doesn't have the useful effect that it
used to.
Is there still a way to build a standalone using current LiveCode, that can
operate on a Linux box that can only be accessed on the command line?
TIA,
Ben
