1  Version SVN trunk (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13    
14      * Real-time instrument scripts:
15        - Added method ScriptVM::setExitResultEnabled() which allows to
16          explicitly enable the built-in exit() function to optionally accept
17          one function argument; the value of the passed exit() function
18          argument will then become available by calling
19          VMExecContext::exitResult() after script execution.
20        - 64 bit support for NKSP integer scripts variables (declare $foo).
21        - Variable names, function names and preprocessor condition names must start
22          with a regular character (a-z or A-Z); starting them with a digit or
23          underscore is not allowed.
24        - NKSP parser fix: equal comparison operator "=" and not equal comparison
25          operator "#" must only accept integer operands.
26        - NKSP language: Implemented support for standard units like Hertz, seconds,
27          Bel including support for metric unit prefixes; so one can now e.g.
28          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31        - NKSP language: Introduced "final" operator "!" which is specifically
32          intended for synthesis parameter values to denote that the synthesis
33          parameter value is intended to be the "final" value for that synthesis
34          parameter that should explicitly be used by the engine and thus causing
35          the sampler engine to ignore all other modulation sources for the same
36          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37          variable or formula with this new "!" operator the expression is marked as
38          being "final".
39        - NKSP script editor API: Added support for detecting standard unit tokens
40          and their potential metric prefix token.
41        - NKSP language: Added support for NKSP real number literals and
42          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43        - NKSP language: Added support for NKSP real number (floating point) script
44          variables (declare ~foo).
45        - NKSP language: Added support for NKSP real number (floating point) array
46          script variables (declare ?foo[]).
47        - Built-in script function "message()" accepts now real number argument as
48          well.
49        - Added built-in script function "real_to_int()" and its short hand form
50          "int()" for casting from real number to integer in NKSP scripts.
51        - Added built-in script function "int_to_real()" and its short hand form
52          "real()" for casting from integer to real number in NKSP scripts.
53        - Allow built-in exit() function to potentially accept real number type
54          argument as well.
55        - Built-in script functions may have a different return type depending on
56          the arguments passed to the function.
57        - Built-in script function "abs()" optionally accepts and returns real
58          number.
59        - Built-in script functions "min()" and "max()" optionally accept real
60          number arguments and return real number as result in that case.
61        - NKSP VM API: Allow units and 'final'ness to be returned as result from
62          built-in functions (added methods VMFunction::returnUnitType() and
63          VMFunction::returnsFinal() for that purpose which must be implemented by
64          built-in function implementations).
65        - NKSP language: Allow metric unit prefixes of numeric scalar and array
66          variables to be changed freely at runtime (unlike unit types like Hz etc.
67          which are still sticky, parse-time features of variables which cannot be
68          changed at runtime for the intentional sake of determinism).
69        - NKSP language: 'final' values are prohibited for array variables for now
70          (attempt causes a parsers error).
71        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
72          conditions of runtime control structures like if(), while(), select()
73          (attempt causes a parser error).
74        - NKSP VM API: Allow built-in functions to perform their own, individual
75          parse time checks of arguments going to be passed to the function at
76          runtime (added method VMFunction::checkArgs() for that purpose).
77        - NKSP language: raise parser warning if only one operand of binary
78          operators (like logical 'or' comparison) contain a 'final' value (because
79          it would always yield in a 'final' result in such cases).
80        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
81          different metric unit prefixes, which will behave as expected (e.g.
82          result of expression '1000us < 2ms' is true).
83        - NKSP language: Allow adding values with different metric unit prefixes
84          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
85        - NKSP language: Allow subtracting values with different metric unit
86          prefixes (e.g. result of expression '1ms - 20us' is '980us').
87        - NKSP language: Allow multiplying with any metric unit prefixes
88          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
89          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
90          we don't have any considerable practical use for a term like '4s^2'
91          (hence any attempt multiplying two unit types still causes parser error).
92        - NKSP language: Allow dividing by any metric unit prefixes and allow
93          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
94          yields in unit free result '8'). So this is now a way to cast units away
95          e.g. for passing the result to other expressions, certain function calls
96          or variables which are not accepting any units (or that specific unit).
97        - NKSP language: integer arrays and real number arrays can now be converted
98          to strings (e.g. for dumping their content with message() calls for
99          script debugging purposes).
100        - NKSP language: expressions and variables with units are now correctly
101          casted to strings (e.g. with message() calls).
102        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
103          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
104          floating point tolerances into account.
105        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
106          VMScalarNumberExpr::evalCastReal().
107        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
108          'VMIntArrayExpr' and 'VMRealArrayExpr'.
109        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
110          unitFactor() (runtime) methods.
111        - Built-in function "exit()" supports now returning units and 'final'ness
112          for test cases.
113        - The following built-in functions support now units as well: "abs()",
114          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
115          "real_to_int()", "int()", "int_to_real()" and "real()".
116        - Built-in functions "array_equal()", "search()" and "sort()" support now
117          real number arrays (correctly) as well.
118        - Added individual parse time checks of arguments to be passed to built-in
119          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
120          "array_equal()" and "search()" specific for their individual purposes.
121        - NKSP VM refactoring: Renamed all methods, functions and classes matching
122          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
123          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
124          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
125          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
126          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
127          isScalarNumber() -> isNumber()).
128        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
129          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
130          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
131          as convenient methods for automatically converting values to expected
132          metric value basis.
133        - Built-in function "wait()" accepts now both integers and real numbers as
134          argument.
135        - NKSP VM API cleanup: Get rid of legacy method
136          VMFunction::argType(vmint iArg) which was already superseded by its new
137          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
138        - NKSP parser: if wrong argument type was passed to a built-in function and
139          that built-in function accepts more than one data type for the argument,
140          then show all supported data types as parser error message.
141    
142      * test cases:
143        - Fixed compiler errors in test cases.
144        - Updated README for how to compile & run test cases.
145        - Updated test case
146          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
147          expected behaviour of the Mutex class implementation (recursive
148          mutex type).
149        - Added test cases for NKSP core language aspects and core built-in
150          functions.
151        - Fixed thread tests segfaulting on Linux.
152        - NKSP: Added real number test cases for built-in functions exit(),
153          int_to_real(), real(), real_to_int() and int(), as well as for the
154          plus, minus and negate language operators.
155        - Added massive amount of NKSP test cases for standard measuring units and
156          'final' operator usage cases.
157        - Added NKSP test cases for (floating point tolerance aware) real number
158          equalness / unequalness comparison.
159        - Added NKSP int array and real array tests for value assignment and
160          initialization of arrays.
