![]() a ~ b - converts both values to 32 bit integers, bitwise XOR the values.a & b - converts both values to integer, and returns bitwise AND of values.a | b - converts both values to integer, and returns bitwise OR of values.Use parentheses when mixing these operators. Note: the relative precedence of |, &, and ~ are equal, meaning a mix of these operators is evaluated left-to-right (which is different from other languages and may not be as expected).value + another_value - adds two values and returns the sum.value - another_value - subtracts two values and returns the difference.value * another_value - multiplies two values and returns the product.value / divisor - divides two values and returns the quotient.Note that shifts by more than 32 or less than 0 produce undefined results. value > shift_amt - converts both values to 32 bit integers, bitwise right shifts the first value by the second, with sign-extension (negative values of y produce non-positive results).numerator % denominator - divides two values as integers and returns the remainder.This is also available the function pow(x,y) base ^ exponent - returns the first parameter raised to the power of the second parameter.-value - returns value with a reversed sign (-1 * value).!value - returns the logical NOT of the parameter (if the parameter is 0.0, returns 1.0, otherwise returns 0.0).This option also increases the size of gmem to be 8 million entries (from the default 1 million). So, if you have a single plug-in, or a few plug-ins that access the shared namespace, they can communicate without having to worry about other plug-ins. Which will make gmem refer to a larger shared buffer, accessible by any plugin that uses options:gmem=. The plug-in can also specify a line (before code sections): If 'gmem' is specified as the left parameter to the brackets, then the global shared buffer is used, which is approximately 1 million (1,048,576) slots that are shared across all instances of all JSFX effects. If a value in the brackets is omitted then only the value to the left of the brackets is used. The sum of the value to the left of the brackets and the value within the brackets is used to index memory. Your effect has approximately 8 million (8,388,608) slots of memoryĪnd you may access them either with fixed offsets (i.e. You may use brackets to index into memory that is local to your effect. Listed from highest precedence to lowest (but one should use parentheses whenever there is doubt!): /* comments block of code that span lines or be part of a line */.If you wish to generate a mask of 1 bits in integer, you can use $~X, for example $~7 is 127, $~8 is 255, $~16 is 65535, etc.You may specify the ASCII value of a character using $'c' (where c is the character).(REAPER v4.25+ can also take traditional C syntax, i.e. Numbers are in normal decimal, however if you prefix an '$x' to them, they will be hexadecimal (i.e.User definable functions, which can define private variables, parameters, and also can optionally access namespaced instance variables.These variables are shared between all JSFX plug-in instances. Shared global named variables, accessible via the "_global." prefix.These words are shared between all JSFX plug-in instances. A shared global address space of about 1 million words, accessed via gmem.A virtual local address space of about 8 million words, which can be accessed via brackets "".A semicolon " " is used to separate statements from eachother (including within parentheses).Parentheses "(" and ")" can be used to clarify precedence, contain parameters for functions, and collect multiple statements into a single statement.These all convert to integer for calculation. Bitwise operations including OR (|), AND (&), XOR (~), shift-left (>).Basic operations including addition (+), subtraction (-), multiplication (*), division (/), and exponential (^).There are a few predefined constant variables: $pi, $phi, and $e.characters, though this is used for namespaced pseudo-objects. The maximum variable name length is 127 characters.Variable names may begin with a _, a-z, or A-Z, and can contain numbers after one of those characters.Variable names are NOT case sensitive, so a and A refer to the same variable.Variables do not need to be declared, are by default global to the effect, and are all double-precision floating point.Some basic features of this language are: Code is written in one or more of the numerous code sections. The core of JSFX is custom code written in a simple language (called EEL2), which has many similarities to C. JSFX Programming Reference - Language Essentials
