combined some awk options into QSE_AWK_EXTRAKWS.
deleted QSE_AWK_EXTRAOPS and enabled all new operators by default added === and !==. fixed a bug in printing the explicit concatenation operator(%%, %%=) improved @include handling

@section awk_ext AWK LANGUAGE EXTENSIONS
|
||||
Some language extensions are implemented and those can be enabled by setting
|
||||
the corresponding options.
|
||||
@subsection awk_litvar LITERAL AND VARIABLE
|
||||
|
||||
Value type
|
||||
- Scalar
|
||||
-- String
|
||||
-- Integer
|
||||
-- Floating-Pointer number
|
||||
- Hashed Map
|
||||
- Regular expression
|
||||
|
||||
Scalar values are immutable while a hashed map value is mutable.
|
||||
A regular expression value is specially treated.
|
||||
|
||||
A variable is tied to a value when it is assigned with a value.
|
||||
If the variable is tied to a map value, it can't be assigned again.
|
||||
You can use 'reset' to untie the variable from the value, and thus
|
||||
restore the variable to the 'nil' state.
|
||||
|
||||
....
|
||||
|
||||
@subsection awk_ext_teq TEQ OPERATOR
|
||||
|
||||
The === operator compares two values and evaluates to a non-zero value
|
||||
if both have the same internal type and the actual values are the same.
|
||||
so 1 is not equal to 1.0 for the === operator.
|
||||
|
||||
A map comparison for the === operator is a bit special. The contents of
|
||||
the map is never inspected. Comparing two maps always result in inequality.
|
||||
|
||||
However, if two variables points to the same map value, it can evaluate
|
||||
to a non-zero value. This is possible if you allow assigning a map to
|
||||
another non-map variable with #QSE_AWK_MAPTOVAR. In this case, a map
|
||||
is not deep-copied but the reference to it is copied.
|
||||
|
||||
@code
|
||||
BEGIN {
|
||||
a[10]=20;
|
||||
b=a;
|
||||
b[20]=40;
|
||||
for (i in a) print i, a[i];
|
||||
print a===b;
|
||||
}
|
||||
@endcode
|
||||
|
||||
|
||||
The === operator may be also useful when you want to indicate an error
|
||||
with an uninitialized variable. The following code check if the function
|
||||
returned a map. Since the variable 'nil' has never been assigned, its
|
||||
internal type is 'NIL' and
|
||||
|
||||
@code
|
||||
function a ()
|
||||
{
|
||||
x[10] = 2;
|
||||
return x;
|
||||
}
|
||||
|
||||
BEGIN {
|
||||
t = a();
|
||||
if (t === nil)
|
||||
print "nil";
|
||||
else
|
||||
print "ok";
|
||||
}
|
||||
@endcode.
|
||||
|
||||
The !== operator is a negated form of the === operator.
