NKSP VM refactoring: Renamed all methods, functions and classes matching pattern '*ScalarNumber*' to simply '*Number*': - Renamed classes VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr, ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp -> NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction. - Renamed method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(). - Renamed function isScalarNumber() -> isNumber().
NKSP: Allow more wider support of standard measuring units & 'final'ness. * Raised compiler requirement to be C++14 compliant (due to severe restrictions regarding C-style aggregate initializer lists in C++11 which are now massively used throughout the code base). * NKSP VM API: Allow units and 'final'ness to be returned as result from built-in functions (added methods VMFunction::returnUnitType() and VMFunction::returnsFinal() for that purpose which must be implemented by built-in function implementations). * NKSP language: Allow metric unit prefixes of numeric scalar and array variables to be changed freely at runtime (unlike unit types like Hz etc. which are still sticky parse-time features of variables which cannot be changed at runtime for the intentional sake of determinism). * NKSP language: 'final' values are prohibited for array variables for now (attempt causes a parsers error). * NKSP language: expressions with unit types (e.g. Hz) are prohibited for conditions of runtime control structures like if(), while(), select() (attempt causes a parser error). * NKSP VM API: Allow built-in functions to perform their own, individual parse time checks of arguments going to be passed to the function at runtime (added method VMFunction::checkArgs() for that purpose). * NKSP language: raise parser warning if only one operand of binary operators (like logical 'or' comparison) contain a 'final' value (because it would always yield in a 'final' result in such cases). * NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with different metric unit prefixes, which will behave as expected (e.g. result of expression '1000us < 2ms' is true). * NKSP language: Allow adding values with different metric unit prefixes (e.g. result of expression '100Hz + 5kHz' is '5100Hz'). * NKSP language: Allow subtracting values with different metric unit prefixes (e.g. result of expression '1ms - 20us' is '980us'). * NKSP language: Allow multiplying with any metric unit prefixes (e.g. result of expression '2k * 3ms' is '6s'), however multiplications with unit types on both sides (e.g. '2s * 2s') is still prohibited since we don't have any considerable practical use for a term like '4s^2' (hence any attempt multiplying two unit types still causes parser error). * NKSP language: Allow dividing by any metric unit prefixes and allow division of same unit type on both sides (e.g. expression '8kHz / 1000Hz' yields in unit free result '8'). So this is now a way to cast units away e.g. for passing the result to other expressions, certain function calls or variables which are not accepting any units (or that specific unit). * NKSP language: integer arrays and real number arrays can now be converted to strings (e.g. for dumping their content with message() calls for script debugging purposes). * NKSP language: expressions and variables with units are now correctly casted to strings (e.g. with message() calls). * NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected floating point tolerances into account. * NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and VMScalarNumberExpr::evalCastReal(). * NKSP VM API: Added base class 'VMNumberArrayExpr' for classes 'VMIntArrayExpr' and 'VMRealArrayExpr'. * NKSP VM API: replaced all unitPrefix() (parse time) methods by unitFactor() (runtime) methods. * Built-in function "exit()" supports now returning units and 'final'ness exclusively for test cases. * The following built-in functions support now units as well: "abs()", "random()", "inc()", "dec()", "in_range()", "min()", "max()", "real_to_int()", "int()", "int_to_real()" and "real()". * Built-in functions "array_equal()", "search()" and "sort()" support now real number arrays (correctly) as well. * Added individual parse time checks of arguments to be passed to built-in functions "random()", "inc()", "dec()", "in_range()", "min()", "max()", "array_equal()" and "search()" specific for their individual purposes. * Test cases: Added massive amount of NKSP test cases for standard measuring units and 'final' operator usage cases. * Test cases: Added NKSP test cases for (floating point tolerance aware) real number equalness / unequalness comparison. * Bumped version (2.1.1.svn8).
NKSP: Introducing floating point support. * NKSP language: Added support for NKSP real number literals and arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0"). * NKSP language: Added support for NKSP real number (floating point) script variables (declare ~foo := 3.4). * NKSP language: Added support for NKSP real number (floating point) array script variables (declare ?foo[3] := ( 1.1, 2.7, 49.0 )). * NKSP built-in script function "message()" accepts now real number argument as well. * Added built-in NKSP script function "real_to_int()" and its short hand form "int()" for casting from real number to integer in NKSP scripts. * Added built-in NKSP script function "int_to_real()" and its short hand form "real()" for casting from integer to real number in NKSP scripts. * Bumped version (2.1.1.svn6).
NKSP: Bug fixes regarding new measurement units feature: * Fix: Engine internal Fade of script synthesis parameters volume, pitch and pan were not rendered at all. * Fix: Backward compatibility of built-in function arguments without a metric unit prefix was broken (resulted in incorrect value transformation). * Fix: built-in script function change_play_pos() resolved wrong arguments. * Bumped version (2.1.1.svn5).
* NKSP script editor API: Added support for detecting standard unit tokens and their potential metric prefix token.
NKSP: Added standard units support for numbers and final "!" operator: * NKSP strictness: Variable names, function names and preprocessor condition names must start with a regular character (a-z or A-Z); starting them with a digit or underscore is no longer allowed. * NKSP parser fix: equal comparison operator "=" and not equal comparison operator "#" must only accept integer operands. * NKSP language: Implemented support for standard units like Hertz, seconds, Bel including support for metric unit prefixes; so one can now e.g. conveniently use numbers in scripts like "5us" meaning "5 microseconds", or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning). * NKSP language: Introduced "final" operator "!" which is specifically intended for synthesis parameter values to denote that the synthesis parameter value is intended to be the "final" value for that synthesis parameter that should explicitly be used by the engine and thus causing the sampler engine to ignore all other modulation sources for the same synthesis parameter (like e.g. LFO, EG); by simply prefixing a value, variable or formula with this new "!" operator the expression is marked as being "final". * Bumped version (2.1.1.svn4).
* NKSP: Implemented built-in script function "inc()". * NKSP: Implemented built-in script function "dec()". * NKSP language fix: division expressions were evaluated too often. * NKSP language fix: string concatenation operator was right associative instead of left (to right). * Bumped version (2.0.0.svn15).
* Instrument script classes now exported with the liblinuxsampler C++ API. * Added new API method ScriptVM::syntaxHighlighting() which provides a convenient syntax highlighting backend for external instrument script editor applications. * Bumped version (2.0.0.svn5).
* Implemented built-in instrument script function "abs()". * Implemented built-in instrument script function "random()". * Implemented built-in instrument script function "num_elements()". * Disabled debug mode of RefPtr template class. * Bumped version (1.0.0.svn51).
* ScriptVM (WIP): Built-in script function "play_note()" now returns the event ID of the triggered note. * ScriptVM (WIP): Implemented built-in script int variable $EVENT_ID. * ScriptVM (WIP): Implemented built-in script function "ignore_event()". * ScriptVM (WIP): Implemented built-in script function "ignore_controller()" (accepts one and no argument). * Bumped version (1.0.0.svn44).
* ScriptVM (WIP): Implemented execution of script event handlers "note" and "release". * ScriptVM (WIP): Implemented built-in script function "play_note()" (only two of the max. four function arguments are currently implemented yet though). * ScriptVM (WIP): Fixed incorrect handling of suspended scripts. * Bumped version (1.0.0.svn43).
