80ed641d69 avoid unnecessary call() 2008-02-13 20:12:42 +00:00
andy
4ae206fc00 Turns out some code likes to call isa() with non-objects. Might as 
well have it return false (which is valid) instead of throwing an
exception (also valid, but more surprising).

fc6f357a0e add new debugging function proptrace(), which outputs all regular property 
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

256b1880cb wrapNode(): One argument ought to be enough for anybody. 2007-10-15 18:32:20 +00:00

2bcddab9b6 setlistener(): accessing the node via cmdarg() is now depreciated. Use 
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);

0d3c7cec6f - setlistener(): add wrapper function to turn ghost arguments into props.Nodes 
- "modernization": use more named function arguments and "var" keywords

bf050c012f load and execute all ~/.fgfs/Nasal/*.nas files in alphabetic order after 
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

30502189d8 The screen-capture command no longer pops up a dialog, so toss up a tip 
from within the F3 keybaord handler instead.

1e446a26ae setlistener(): don't drop calls with invalid property -- the c++ side 
outputs a nice error message in this case

944e6a8548 in debug levels "debug" and "bulk" output listener id, file name, and 
line-number for every setlistener() wrapper call. This allows to identify
listeners later by their id.

cde64c8543 use __ for static variables (one underscore is too handy for use in other

printlog("warn", "Monty", "Burns");

003ae0986f add printlog() function that works like SG_LOG(). It takes two arguments: 
a --log-level and a scalar. Example: printlog("info", "I want more noise");

523b81e317 globals.nas: add _setlistener wrapper (needs to be used in INIT style 
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

f1c70da6d4 Fix interpolate() so that interpolate("/prop/name") freezes the 
interpolation at the current value.  This was always a feature of the
C++ code, but the Nasal wrapper couldn't handle the empty argument
list.

57eea1be61 Melchior needs an equivalent of Perl's defined() function to test for 
double-initialization of joystick blocks.  So here it is.

3677b96fad Bugfix to globals.fgcommand(). 
New Node.setValues() method which sets whole property trees from Nasal
data.

A view.nas module, which takes over handling of the X/x zoom keys.  It
clamps the FOV to a dynamically calculated maximum corresponding to
typical human visual accuity, and pops up a pretty dialog informing
you of the new FOV.
