|

|
"""
|
||
|
|
Holder class for uniform access to SCons options, regardless
|
||
|
|
of whether or not they can be set on the command line or in the
|
||
|
|
SConscript files (using the SetOption() function).
|
||
|
|
|
||
|
|
A SCons option value can originate three different ways:
|
||
|
|
|
||
|
|
1) set on the command line;
|
||
|
|
2) set in an SConscript file;
|
||
|
|
3) the default setting (from the the op.add_option()
|
||
|
|
calls in the Parser() function, below).
|
||
|
|
|
||
|
|
The command line always overrides a value set in a SConscript file,
|
||
|
|
which in turn always overrides default settings. Because we want
|
||
|
|
to support user-specified options in the SConscript file itself,
|
||
|
|
though, we may not know about all of the options when the command
|
||
|
|
line is first parsed, so we can't make all the necessary precedence
|
||
|
|
decisions at the time the option is configured.
|
||
|
|
|
||
|
|
The solution implemented in this class is to keep these different sets
|
||
|
|
of settings separate (command line, SConscript file, and default)
|
||
|
|
and to override the __getattr__() method to check them in turn.
|
||
|
|
This should allow the rest of the code to just fetch values as
|
||
|
|
attributes of an instance of this class, without having to worry
|
||
|
|
about where they came from.
|
||
|
|
|
||
|
|
Note that not all command line options are settable from SConscript
|
||
|
|
files, and the ones that are must be explicitly added to the
|
||
|
|
"settable" list in this class, and optionally validated and coerced
|
||
|
|
in the set_option() method.
