Fix bug https://sourceforge.net/p/flightgear/codetickets/2219/
Changes to logging mean than setlistener breaks when invoked via
call(), which occurs in the Warthog Nasal scripting. The problem is
that call() forces caller() to return nil, which the setlistener()
debug code did not check for.
- A simple assert() function is added to the globals namespace.
- io.include() marks the target namespace to avoid dependency loops.
If the namespace is marked before the script to be included is
compiled, a parse error leaves the target namespace marked while
the script has not been loaded. This patch fixes this problem.
earlier available. (The settimer/1 was a workaround for another
problem that should be fixed by now.)
globals.nas: load $FG_HOME/Nasal/ files as first settimer(0) function,
so that it always comes after all nasal-dir-initialized callbacks
This should fix the glide_slope_tunnel/popupTip bug and makes the
startup order clearer and cleaner.
- fuel.nas: use props.initNode()
- debug.nas: fix comment
- globals.nas: load_nasal(): check extension and set module arg
- io.nas: update log message (the rules are no longer for io.open() only)
writes (not directly written tied ones), all node additions and removal.
Frames are separated with a line. Turn off ANSI coloring if you want to
pipe the results into a file: --prop:sim/startup/terminal-ansi-colors=0
a regular function argument for that. Note the "n" in this example:
setlistener("/sim/current-view/view-number", func(n) {
setprop("/sim/hud/visibility", !n.getValue());
}, 1);
the $FG_ROOT/Nasal/*.nas ones are done. This allows to use props.Node etc.
immediately, without requirement for settimer(func{}, 0) constructions.
Rationale:
- clean separation of local additions (and hacks :-) from standard files
- users might not have write permission to $FG_ROOT/Nasal/ or shouldn't
have to su to root for writing Nasal code
functions when used in $FG_ROOT/Nasal/*.nas, because it
depends on props.nas being available; no restrictions in
aircraft files, where it will proof most useful
