- 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 |

(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 |
|

LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld, |
| 24 |
|
SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr, |

| 36 |
|
- 64 bit support for NKSP integer scripts variables (declare $foo). |
| 37 |
|
- Variable names, function names and preprocessor condition names must start |
| 38 |
|
with a regular character (a-z or A-Z); starting them with a digit or |
| 39 |
|
underscore is not allowed. |
| 40 |
|
- NKSP parser fix: equal comparison operator "=" and not equal comparison |
| 41 |
|
operator "#" must only accept integer operands. |
| 42 |
|
- NKSP language: Implemented support for standard units like Hertz, seconds, |
| 43 |
|
Bel including support for metric unit prefixes; so one can now e.g. |
| 44 |
|
conveniently use numbers in scripts like "5us" meaning "5 microseconds", |
| 45 |
|
or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning |
| 46 |
|
"minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning). |
| 47 |
|
- NKSP language: Introduced "final" operator "!" which is specifically |
| 48 |
|
intended for synthesis parameter values to denote that the synthesis |
| 49 |
|
parameter value is intended to be the "final" value for that synthesis |
| 50 |
|
parameter that should explicitly be used by the engine and thus causing |
| 51 |
|
the sampler engine to ignore all other modulation sources for the same |
| 52 |
|
synthesis parameter (like e.g. LFO, EG); by simply prefixing a value, |
| 53 |
|
variable or formula with this new "!" operator the expression is marked as |
| 54 |
|
being "final". |
| 55 |
|
- NKSP script editor API: Added support for detecting standard unit tokens |
| 56 |
|
and their potential metric prefix token. |
| 57 |
|
- NKSP language: Added support for NKSP real number literals and |
| 58 |
|
arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0"). |
| 59 |
|
- NKSP language: Added support for NKSP real number (floating point) script |
| 60 |
|
variables (declare ~foo). |
| 61 |
|
- NKSP language: Added support for NKSP real number (floating point) array |
| 62 |
|
script variables (declare ?foo[]). |
| 63 |
|
- Built-in script function "message()" accepts now real number argument as |
| 64 |
|
well. |
| 65 |
|
- Added built-in script function "real_to_int()" and its short hand form |
| 66 |
|
"int()" for casting from real number to integer in NKSP scripts. |
| 67 |
|
- Added built-in script function "int_to_real()" and its short hand form |
| 68 |
|
"real()" for casting from integer to real number in NKSP scripts. |
| 69 |
|
- Allow built-in exit() function to potentially accept real number type |
| 70 |
|
argument as well. |
| 71 |
|
- Built-in script functions may have a different return type depending on |
| 72 |
|
the arguments passed to the function. |
| 73 |
|
- Built-in script function "abs()" optionally accepts and returns real |
| 74 |
|
number. |
| 75 |
|
- Built-in script functions "min()" and "max()" optionally accept real |
| 76 |
|
number arguments and return real number as result in that case. |
| 77 |
|
- NKSP VM API: Allow units and 'final'ness to be returned as result from |
| 78 |
|
built-in functions (added methods VMFunction::returnUnitType() and |
| 79 |
|
VMFunction::returnsFinal() for that purpose which must be implemented by |
| 80 |
|
built-in function implementations). |
| 81 |
|
- NKSP language: Allow metric unit prefixes of numeric scalar and array |
| 82 |
|
variables to be changed freely at runtime (unlike unit types like Hz etc. |
| 83 |
|
which are still sticky, parse-time features of variables which cannot be |
| 84 |
|
changed at runtime for the intentional sake of determinism). |
| 85 |
|
- NKSP language: 'final' values are prohibited for array variables for now |
| 86 |
|
(attempt causes a parsers error). |
| 87 |
|
- NKSP language: expressions with unit types (e.g. Hz) are prohibited for |
| 88 |
|
conditions of runtime control structures like if(), while(), select() |
| 89 |
|
(attempt causes a parser error). |
| 90 |
|
- NKSP VM API: Allow built-in functions to perform their own, individual |
| 91 |
|
parse time checks of arguments going to be passed to the function at |
| 92 |
|
runtime (added method VMFunction::checkArgs() for that purpose). |
| 93 |
|
- NKSP language: raise parser warning if only one operand of binary |
| 94 |
|
operators (like logical 'or' comparison) contain a 'final' value (because |
| 95 |
|
it would always yield in a 'final' result in such cases). |
| 96 |
|
- NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with |
| 97 |
|
different metric unit prefixes, which will behave as expected (e.g. |
| 98 |
|
result of expression '1000us < 2ms' is true). |
| 99 |
|
- NKSP language: Allow adding values with different metric unit prefixes |
| 100 |
|
(e.g. result of expression '100Hz + 5kHz' is '5100Hz'). |
| 101 |
|
- NKSP language: Allow subtracting values with different metric unit |
| 102 |
|
prefixes (e.g. result of expression '1ms - 20us' is '980us'). |
| 103 |
|
- NKSP language: Allow multiplying with any metric unit prefixes |
| 104 |
|
(e.g. result of expression '2k * 3ms' is '6s'), however multiplications |
| 105 |
|
with unit types on both sides (e.g. '2s * 2s') is still prohibited since |
| 106 |
|
we don't have any considerable practical use for a term like '4s^2' |
| 107 |
|
(hence any attempt multiplying two unit types still causes parser error). |
| 108 |
|
- NKSP language: Allow dividing by any metric unit prefixes and allow |
| 109 |
|
division of same unit type on both sides (e.g. expression '8kHz / 1000Hz' |
| 110 |
|
yields in unit free result '8'). So this is now a way to cast units away |
| 111 |
|
e.g. for passing the result to other expressions, certain function calls |
| 112 |
|
or variables which are not accepting any units (or that specific unit). |
| 113 |
|
- NKSP language: integer arrays and real number arrays can now be converted |
| 114 |
|
to strings (e.g. for dumping their content with message() calls for |
| 115 |
|
script debugging purposes). |
| 116 |
|
- NKSP language: expressions and variables with units are now correctly |
| 117 |
|
casted to strings (e.g. with message() calls). |
| 118 |
|
- NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or |
| 119 |
|
unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected |
| 120 |
|
floating point tolerances into account. |
| 121 |
|
- NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and |
| 122 |
|
VMScalarNumberExpr::evalCastReal(). |
| 123 |
|
- NKSP VM API: Added base class 'VMNumberArrayExpr' for classes |
| 124 |
|
'VMIntArrayExpr' and 'VMRealArrayExpr'. |
| 125 |
|
- NKSP VM API: replaced all unitPrefix() (parse time) methods by |
| 126 |
|
unitFactor() (runtime) methods. |
| 127 |
|
- Built-in function "exit()" supports now returning units and 'final'ness |
| 128 |
|
for test cases. |
| 129 |
|
- The following built-in functions support now units as well: "abs()", |
| 130 |
|
"random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 131 |
|
"real_to_int()", "int()", "int_to_real()" and "real()". |
| 132 |
|
- Built-in functions "array_equal()", "search()" and "sort()" support now |
| 133 |
|
real number arrays (correctly) as well. |
| 134 |
|
- Added individual parse time checks of arguments to be passed to built-in |
| 135 |
|
functions "random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 136 |
|
"array_equal()" and "search()" specific for their individual purposes. |
| 137 |
|
- NKSP VM refactoring: Renamed all methods, functions and classes matching |
| 138 |
|
pattern *ScalarNumber* to simply *Number* (that is i.e. classes |
| 139 |
|
VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr, |
| 140 |
|
ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp -> |
| 141 |
|
NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction, |
| 142 |
|
method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function |
| 143 |
|
isScalarNumber() -> isNumber()). |
| 144 |
|
- NKSP VM API: Added 4 overridden methods to class VMNumberExpr: |
| 145 |
|
evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t), |
| 146 |
|
evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t) |
| 147 |
|
as convenient methods for automatically converting values to expected |
| 148 |
|
metric value basis. |
| 149 |
|
- Built-in function "wait()" accepts now both integers and real numbers as |
| 150 |
|
argument. |
| 151 |
|
- NKSP VM API cleanup: Get rid of legacy method |
| 152 |
|
VMFunction::argType(vmint iArg) which was already superseded by its new |
| 153 |
|
replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type). |
| 154 |
|
- NKSP parser: if wrong argument type was passed to a built-in function and |
| 155 |
|
that built-in function accepts more than one data type for the argument, |
| 156 |
|
then show all supported data types as parser error message. |
| 157 |
|
- Built-in function "play_note()" accepts now real numbers and seconds as |
| 158 |
|
unit type as well for its 3rd and 4th function arguments. |
| 159 |
|
- The following built-in functions accept now real numbers as well for their |
| 160 |
|
2nd function argument: "change_vol()", "change_tune()", "change_cutoff()", |
| 161 |
|
"change_attack()", "change_decay()", "change_release()", |
| 162 |
|
"change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()", |
| 163 |
|
"change_cutoff_sustain()", "change_cutoff_release()", |
| 164 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 165 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 166 |
|
"change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()". |
| 167 |
|
- Fixed built-in function "change_play_pos()" not having accepted metric |
| 168 |
|
prefixes at all. |
| 169 |
|
- Fixed the following built-in functions having misinterpreted values given |
| 170 |
|
with unit type (for their 2nd argument) as if they were relative values |
| 171 |
|
(that is as if they were passed without a unit type): "change_attack()", |
| 172 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 173 |
|
"change_cutoff_decay()", "change_cutoff_release()". |
| 174 |
|
- Fixed the following built-in functions having applied completely wrong |
| 175 |
|
'final' values: "change_sustain()", "change_cutoff_sustain()" (since the |
| 176 |
|
respective EGs being their modulation sink assume uint data type with |
| 177 |
|
value range 0..1000 instead of 0.0..1.0. |
| 178 |
|
- Added individual parse-time checks of function arguments for the following |
| 179 |
|
built-in functions: "play_note()", "note_off()", "set_event_mark()", |
| 180 |
|
"delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()", |
| 181 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 182 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 183 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 184 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and |
| 185 |
|
"change_pan_time()". |
| 186 |
|
- Don't abort function call if unit type was used and at the same time |
| 187 |
|
'final' operator was omitted for the primary value argument of the |
| 188 |
|
following built-in functions: "change_cutoff()", "change_attack()", |
| 189 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 190 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 191 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 192 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 193 |
|
"change_pan_time()", instead imply 'final'ness at runtime and raise an |
| 194 |
|
appropriate parser warning at parse time. |
| 195 |
|
- Added built-in real number functions "round()", "ceil()", "floor()", |
| 196 |
|
"sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", |
| 197 |
|
"cos()", "tan()", "asin()", "acos()", "atan()". |
| 198 |
|
- Added built-in script real number constant "~NI_MATH_PI". |
| 199 |
|
- Added built-in script real number constant "~NI_MATH_E". |
