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).

File length: 21967 byte(s)
Diff to previous 3573
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").

  script variables (declare ~foo := 3.4).

  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).

* 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

  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.

  special value -1 for "duration-us" argument, which will cause the

* Fixed crash when loading an instrument script.
* Fixed "init" script handler only to be executed once:
  when the script was loaded.
* Fixed aftertouch script event which always had value zero
  and controller number was set to aftertouch value instead.
* gig Engine: Fixed handling of "smartmidi" dimension, which
  was recognized as "unknown" dimension.
* Fixed script function gig_set_dim_zone(): was accessing
  wrong event.
* ls_instr_script command line tool: is now not limited to
  core language scripts, but can now also parse sampler format
  dependent instrument scripts, with the respective specific
  built-in script variables and functions.
* ScriptVM: Fixed runtime behavior of "and" and "or" binary
  script expressions, which also evaluated the right hand side
  of the expression even if the left hand side already failed
  the overall expression semantic to become true.
* Bumped version (1.0.0.svn46).

* 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).

* (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).
