Sticky Revision: |
* ScriptVM: Fixed crash when handling array results of built-in functions (e.g. "num_elements(by_marks($MARK_1)"). * Bumped version (2.1.1.svn69).
* ScriptVM: Fixed incorrect polyphonic data transfer from wrong "note" handler to "release" handler; which also fixes no "release" handler being executed sometimes, and due to the latter it also fixes potential crashes as some polyphonic script events were never released and the engine hence was running out of free script events. * Bumped version (2.1.1.svn68).
* NKSP parser: fixed memory leak; string tokens were allocated as C strings and never freed. * Bumped version (2.1.1.svn66).
NKSP: Fixed built-in exit() function to behave as return statement. * VM API: Introduced new signal STMT_RETURN_SIGNALLED. * NKSP exit() function: signal STMT_RETURN_SIGNALLED instead of STMT_ABORT_SIGNALLED. * NKSP AST: Introduced common base class 'Subroutine' for 'EventHandler' and for new 'UserFunction' class. * NKSP parser: Use 'UserFunction' class instead of 'Statements' class for user declared NKSP functions. * ScriptVM: Handle new STMT_RETURN_SIGNALLED signal by unwinding the stack to previous, calling subroutine. * NKSP tests: Added test cases for exit() acting as return statement. * Bumped version (2.1.1.svn62).
* NKSP: Fixed re-entrant issue with function calls which caused wrong result values if the same function was called multiple times in a term (specifically if metric prefixes were used). * Tests: Added NKSP core language test cases to guard this fixed issue. * Bumped version (2.1.1.svn50).
NKSP: Added support for 'patch' variables. * NKSP language: Added support for 'patch' variable qualifier (as new dedicated keyword 'patch'). * NKSP parser: capture locations of 'patch' variable declarations in script's source code. * ScriptVM: Allow patching 'patch' script variables by replacing their default assignment expression with a supplied replacement variable initialization expression by optional 2nd argument when calling loadScript(). * ScriptVM: Allow retrieval of default initialization expressions of all 'patch' variables by optional 3rd argument when calling loadScript() (i.e. for instrument editors). * gig engine: Implemented support for loading real-time instrument scripts with 'patch' variables bundled with gig instruments. * Bumped version (2.1.1.svn46).
NKSP parser: track code locations also by raw byte position and length. * NKSP VM API: Added member variables 'firstByte' and 'lengthBytes' to struct 'CodeBlock'. * NKSP Editor API: Added methods firstByte() and lengthBytes() to class 'VMSourceToken'. * NKSP VM language parser: track all positions also by raw byte offset and length (along to the already existing tracking by line/column). * NKSP editor syntax highlighting scanner: track all positions also by raw byte offset and length (along to the already existing tracking by line/column). * Bumped version (2.1.1.svn45).
NKSP: Reduced code for parsing NKSP variable declarations: * Use 2 generalized grammar rules with optional components (i.e. optional value assignment and optional variable qualifiers) instead of previous linear combinations of grammar rules, which also fixes some edge case. * Bumped version (2.1.1.svn44).
* NKSP: Fixed certain built-in variables having returned some (seemingly random) metric unit factor (instead of none). * Bumped version (2.1.1.svn32).
NKSP: Added support for RPN and NRPN event handlers: * NKSP language: Added support for RPN event handler ("on rpn ... end on" in instrument scripts). * NKSP language: Added support for NRPN event handler ("on nrpn ... end on" in instrument scripts). * Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which may be read from the new RPN/NRPN script handlers to get the (N)RPN parameter that had been changed and its new value. * Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN" which are identifying the new (N)RPN handlers as such at script runtime. * Bumped version (2.1.1.svn30).
* Fixed compiler errors with GCC 8.x. * Bumped version (2.1.1.svn16).
NKSP: Implemented common real number math functions. * Added built-in real number functions "round()", "ceil()", "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", "cos()", "tan()", "asin()", "acos()", "atan()". * Added built-in script real number constant "~NI_MATH_PI". * Added built-in script real number constant "~NI_MATH_E". * Added NKSP test cases for built-in functions "round()", "ceil()", "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", "cos()", "tan()", "asin()", "acos()", "atan()". * Bumped version (2.1.1.svn14).
* NKSP language: Fixed assignment to array variables which was broken by floating point support introduction (svn r3573). * Test cases: Added NKSP int array and real array tests for value assignment and initialization of arrays. * Bumped version (2.1.1.svn11).
NKSP: Cleanup regarding multiple data types for built-in function args. * NKSP VM API cleanup: Get rid of legacy method VMFunction::argType(vmint iArg) which was already superseded by its new replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type). * NKSP parser: if wrong argument type was passed to a built-in function and that built-in function accepts more than one data type for the argument, then show all supported data types as parser error message. * Bumped version (2.1.1.svn10).
Moved function exprTypeOfVarName() from public API file common.h to implementation internal file tree.h (since this function is only intended to be called by the generated NKSP parser).
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: Fixed negate operator which did not work with real numbers.
NKSP: Added some initial floating point test cases. * RTMath: Implemented floating point comparison methods fEqual32(float,float) and fEqual64(double,double) which take the expected floating point tolerances into account. * NKSP: Allow built-in exit() function to potentially accept real type argument as well. * NKSP: Added real number test cases for built-in functions exit(), int_to_real(), real(), real_to_int() and int(), as well as for the plus, minus and negate language operators.
NKSP: Cleanup of class inheritance scheme. * scriptvm/tree.h: Mark all relevant classes with C++11 'final' keyword. * scriptvm/tree.h: StringLiteral class has no need for virtually.
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: 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: Introducing 64 bit support for NKSP integer scripts variables (declare $foo). * Require C++11 compiler support. * Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used for checking in configure for C++11 support (as mandatory requirement) and automatically adds compiler argument if required (e.g. -std=C++11). * Bumped version (2.1.1.svn3).
* Added test cases for NKSP core language aspects and core built-in functions. * NKSP: Added method ScriptVM::setExitResultEnabled() which allows to explicitly enable the built-in exit() function to optionally accept one function argument; the value of the passed exit() function argument will then become available by calling VMExecContext::exitResult() after script execution. * Bumped version (2.1.1.svn2).
* Fixed some compiler warnings * Fixed compilation error when cross-compiling to Mac

* Added new C++ API class "ScriptVMFactory". * Instrument Scripts: extended parser issues to provide not only first line and first column, but also last line and last column of issue (thus marking the precise span of the issue within the source code). * Bumped version (2.0.0.svn7).
* Instrument Scripts: Fixed line numbers on parser error/warning messages. * Instrument Scripts: Added output of precise column on parser error/warning messages. * Shut up some irrelevant errors of parser generating shell scripts. * Bumped version (2.0.0.svn6).
* All engines: Active voices are now internally grouped to "Note" objects, instead of being directly assigned to a keyboard key. This allows more fine graded processing of voices, which is i.e. required for certain instrument script features. * Built-in script function "play_note()": Added support for passing special value -1 for "duration-us" argument, which will cause the triggered note to be released once the original note was released. * Bumped version (2.0.0.svn3).
* All engines: Implemented scheduler for delayed MIDI events and for suspended real-time instrument scripts. * Real-Time instrument scripts: Implemented support for built-in "wait()" function's "duration-us" argument, thus scripts using this function are now correctly resumed after the requested amount of microseconds. * Real-Time instrument scripts: Implemented support for built-in "play_note()" function's "duration-us" argument, thus notes triggered with this argument are now correctly released after the requested amount of microseconds. * Real-Time instrument scripts: Fixed crash which happened when trying to reference an undeclared script variable. * Real-Time instrument scripts: Script events were not cleared when engine channel was reset, potentially causing undefined behavior. * All engines: Attempt to partly fix resetting engine channels vs. resetting engine, an overall cleanup of the Reset*(), ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be desirable though, because the current situation is still inconsistent and error prone. * Bumped version (2.0.0.svn2).
* RT instrument scripts: Pass/preserve polyphonic variable data from respective "note" event handler to "release" event handler. * Fixed theoretical memory leak regarding instrument scripts. * Bumped version (1.0.0.svn54).

* ScriptVM (WIP): started to integrate real-time instrument script support into the sampler engine implementations. The code is shared among all sampler engines, however currently only the gig file format supports storing instrument scripts (as LinuxSampler extension to the original GigaStudio 4 file format). * gig engine: Added support for loading instrument scripts from .gig files. * ScriptVM (WIP): Implemented built-in script variables %CC, $CC_NUM, $EVENT_NOTE, $EVENT_VELOCITY, $VCC_MONO_AT, $VCC_PITCH_BEND. * ScriptVM (WIP): Implemented execution of script event handler "init". * ScriptVM (WIP): Implemented execution of script event handler "controller". * Bumped version (1.0.0.svn42).
* ScriptVM: refactoring and fixes.
* (WIP) Implemented parser and VM for upcoming new real-time instrument script support. It needs yet to be integrated into the sampler's sampler engines. You can toy around for now with the command line tool "ls_instr_script" and i.e. examples showing the core language features under src/scriptvm/examples/. * Bumped version (1.0.0.svn41).
