|
When passing parameters,
|
|
x: means that a value should follow x
|
|
y means that 'y' is a flag, either on or off
|
|
So, the string a:b:def means that we support up to
|
|
5 parameters; two with values and three flags. The following
|
|
should be valid:
|
|
|
|
script run parameters.lua -a 1 -blala -c -de
|
|
|
|
Notice two things:
|
|
1. 'blala' works just like 'b lala', both set 'b' to 'lala'
|
|
2. Flags can be put together, '-de' is the same as '-d -e'
|
|
3. The format -b=lala is *not* supported
|
|
4. The format b lala (without -) is *not* supported

In the future, we may implement so that scripts are invoked directly
|
|
into a 'main' function, instead of being executed blindly. For future
|
|
compatibility, I have done so, but I invoke my main from here.
