The Parse() method can be even 40% faster - than in the previous version. - (Please be aware that the new parser has not been thoroughly tested; - bugs are possible.) - - A new "semi-undocumented" debugging function for printing the bytecode - of the current function (in an asm-like syntax). Mostly useless from - the user's point of view. - - - -============================================================================= - - Preface -============================================================================= - - Often people need to ask some mathematical expression from the user and -then evaluate values for that expression. The simplest example is a program -which draws the graphic of a user-defined function on screen. - - This library adds C-style function string parsing to the program. This -means that you can evaluate the string "sqrt(1-x^2+y^2)" with given values -of 'x' and 'y'. - - The library is intended to be very fast. It byte-compiles the function -string at parse time and interpretes this byte-code at evaluation time. -The evaluation is straightforward and no recursions are done (uses stack -arithmetic). - Empirical tests show that it indeed is very fast (specially compared to -libraries which evaluate functions by just interpreting the raw function -string). - - The library is made in ISO C++ and requires a standard-conforming C++ -compiler. - - -============================================================================= - - Usage -============================================================================= - - To use the FunctionParser class, you have to include "fparser.hh". When -compiling, you have to compile fparser.cc and link it to the main program. -You can also make a library from the fparser.cc (see the help on your -compiler to see how this is done). - - - * Short descriptions of FunctionParser methods: - -------------------------------------------- - -int Parse(const std::string& Function, const std::string& Vars, - bool useDegrees = false); - - Parses the given function and compiles it to internal format. - Return value is -1 if successful, else the index value to the location - of the error. - - -const char* ErrorMsg(void) const; - - Returns an error message corresponding to the error in Parse(), or 0 if - no such error occurred. - - -double Eval(const double* Vars); - - Evaluates the function given to Parse(). - - -int EvalError(void) const; - - Returns 0 if no error happened in the previous call to Eval(), else an - error code >1. - - -void Optimize(); - - Tries to optimize the bytecode for faster evaluation. - - -bool AddConstant(const std::string& name, double value); - - Add a constant to the parser. Returns false if the name of the constant - is invalid, else true. - - -bool AddFunction(const std::string& name, - double (*functionPtr)(const double*), - unsigned paramsAmount); - - Add a user-defined function to the parser (as a function pointer). - Returns false if the name of the function is invalid, else true. - - -bool AddFunction(const std::string& name, FunctionParser&); - - Add a user-defined function to the parser (as a FunctionParser instance). - Returns false if the name of the function is invalid, else true. - - - - * Long descriptions of FunctionParser methods: - ------------------------------------------- - ---------------------------------------------------------------------------- -int Parse(const std::string& Function, const std::string& Vars, - bool useDegrees = false); ---------------------------------------------------------------------------- - - Parses the given function (and compiles it to internal format). - Destroys previous function. Following calls to Eval() will evaluate - the given function. - The strings given as parameters are not needed anymore after parsing. - - Parameters: - Function : String containing the function to parse. - Vars : String containing the variable names, separated by commas. - Eg. "x,y", "VarX,VarY,VarZ,n" or "x1,x2,x3,x4,__VAR__". - useDegrees: (Optional.) Whether to use degrees or radians in - trigonometric functions. (Default: radians) - - Variables can have any size and they are case sensitive (ie. "var", - "VAR" and "Var" are *different* variable names). Letters, digits and - underscores can be used in variable names, but the name of a variable - can't begin with a digit. Each variable name can appear only once in - the string. Function names are not legal variable names. - - Using longer variable names causes no overhead whatsoever to the Eval() - method, so it's completely safe to use variable names of any size. - - The third, optional parameter specifies whether angles should be - interpreted as radians or degrees in trigonometrical functions. - If not specified, the default value is radians. - - Return values: - -On success the function returns -1. - -On error the function returns an index to where the error was found - (0 is the first character, 1 the second, etc). If the error was not - a parsing error returns an index to the end of the string + 1. - - Example: parser.Parse("3*x+y", "x,y"); - - ---------------------------------------------------------------------------- -const char* ErrorMsg(void) const; ---------------------------------------------------------------------------- - - Returns a pointer to an error message string corresponding to the error - caused by Parse() (you can use this to print the proper error message to - the user). If no such error has occurred, returns 0. - - ---------------------------------------------------------------------------- -double Eval(const double* Vars); ---------------------------------------------------------------------------- - - Evaluates the function given to Parse(). - The array given as parameter must contain the same amount of values as - the amount of variables given to Parse(). Each value corresponds to each - variable, in the same order. - - Return values: - -On success returns the evaluated value of the function given to - Parse(). - -On error (such as division by 0) the return value is unspecified, - probably 0. - - Example: - - double Vars[] = {1, -2.5}; - double result = parser.Eval(Vars); - - ---------------------------------------------------------------------------- -int EvalError(void) const; ---------------------------------------------------------------------------- - - Used to test if the call to Eval() succeeded. - - Return values: - If there was no error in the previous call to Eval(), returns 0, - else returns a positive value as follows: - 1: division by zero - 2: sqrt error (sqrt of a negative value) - 3: log error (logarithm of a negative value) - 4: trigonometric error (asin or acos of illegal value) - - ---------------------------------------------------------------------------- -void Optimize(); ---------------------------------------------------------------------------- - - This method can be called after calling the Parse() method. It will try - to simplify the internal bytecode so that it will evaluate faster (it - tries to reduce the amount of opcodes in the bytecode). - - For example, the bytecode for the function "5+x*y-25*4/8" will be - reduced to a bytecode equivalent to the function "x*y-7.5" (the original - 11 opcodes will be reduced to 5). Besides calculating constant expressions - (like in the example), it also performs other types of simplifications - with variable and function expressions. - - This method is quite slow and the decision of whether to use it or - not should depend on the type of application. If a function is parsed - once and evaluated millions of times, then calling Optimize() may speed-up - noticeably. However, if there are tons of functions to parse and each one - is evaluated once or just a few times, then calling Optimize() will only - slow down the program. - Also, if the original function is expected to be optimal, then calling - Optimize() would be useless. - - Note: Currently this method does not make any checks (like Eval() does) - and thus things like "1/0" will cause undefined behaviour. (On the other - hand, if such expression is given to the parser, Eval() will always give - an error code, no matter what the parameters.) If caching this type of - errors is important, a work-around is to call Eval() once before calling - Optimize() and checking EvalError(). - - If the destination application is not going to use this method, - the compiler constant SUPPORT_OPTIMIZER can be undefined at the beginning - of fparser.cc to make the library smaller (Optimize() can still be called, - but it will not do anything). - - (If you are interested in seeing how this method optimizes the opcode, - you can call the PrintByteCode() method before and after the call to - Optimize() to see the difference.) - - ---------------------------------------------------------------------------- -bool AddConstant(const std::string& name, double value); ---------------------------------------------------------------------------- - - This method can be used to add constants to the parser. Syntactically - constants are identical to variables (ie. they follow the same naming - rules and they can be used in the function string in the same way as - variables), but internally constants are directly replaced with their - value at parse time. - - Constants used by a function must be added before calling Parse() - for that function. Constants are preserved between Parse() calls in - the current FunctionParser instance, so they don't need to be added - but once. (If you use the same constant in several instances of - FunctionParser, you will need to add it to all the instances separately.) - - Constants can be added at any time and the value of old constants can - be changed, but new additions and changes will only have effect the next - time Parse() is called. (That is, changing the value of a constant - after calling Parse() and before calling Eval() will have no effect.) - - The return value will be false if the 'name' of the constant was - illegal, else true. If the name was illegal, the method does nothing. - - Example: parser.AddConstant("pi", 3.14159265); - - Now for example parser.Parse("x*pi", "x"); will be identical to the - call parser.Parse("x*3.14159265", "x"); - - ---------------------------------------------------------------------------- -bool AddFunction(const std::string& name, - double (*functionPtr)(const double*), - unsigned paramsAmount); ---------------------------------------------------------------------------- - - This method can be used to add new functions to the parser. For example, - if you would like to add a function "sqr(A)" which squares the value - of A, you can do it with this method (so that you don't need to touch - the source code of the parser). - - The method takes three parameters: - - - The name of the function. The name follows the same naming conventions - as variable names. - - - A C++ function, which will be called when evaluating the function - string (if the user-given function is called there). The C++ function - must have the form: - double functionName(const double* params); - - - The number of parameters the function takes. NOTE: Currently this - value must be at least 1; the parser does not support functions which - take no parameters (this problem may be fixed in the future). - - The return value will be false if the given name was invalid (either it - did not follow the variable naming conventions, or the name was already - reserved), else true. If the return value is false, nothing is added. - - Example: - Suppose we have a C++ function like this: - - double Square(const double* p) - { - return p[0]*p[0]; - } - - Now we can add this function to the parser like this: - - parser.AddFunction("sqr", Square, 1); - - parser.Parse("2*sqr(x)", "x"); - - - IMPORTANT NOTE: If you use the Optimize() method, it will assume that - the user-given function has no side-effects, that is, it always - returns the same value for the same parameters. The optimizer will - optimize the function call away in some cases, making this assumption. - - ---------------------------------------------------------------------------- -bool AddFunction(const std::string& name, FunctionParser&); ---------------------------------------------------------------------------- - - This method is almost identical to the previous AddFunction(), but - instead of taking a C++ function, it takes another FunctionParser - instance. - - There are some important restrictions on making a FunctionParser instance - call another: - - - The FunctionParser instance given as parameter must be initialized - with a Parse() call before giving it as parameter. That is, if you - want to use the parser A in the parser B, you must call A.Parse() - before you can call B.AddFunction("name", A). - - - The amount of parameters in the FunctionParser instance given as - parameter must not change after it has been given to the AddFunction() - of another instance. Changing the number of parameters will result in - malfunction. - - - AddFunction() will fail (ie. return false) if a recursive loop is - formed. The method specifically checks that no such loop is built. - - - As with the other AddFunction(), the number of parameters taken by - the user-defined function must be at least 1 (this may be fixed in - the future). - - Example: - - FunctionParser f1, f2; - f1.Parse("x*x", "x"); - f2.AddFunction("sqr", f1); - - ---------------------------------------------------------------------------- - - Example program: - -#include "fparser.hh" -#include - -int main() -{ - FunctionParser fp; - - int ret = fp.Parse("x+y-1", "x,y"); - if(ret >= 0) - { - std::cerr << "At col " << ret << ": " << fp.ErrorMsg() << std::endl; - return 1; - } - - double vals[] = { 4, 8 }; - - std::cout << fp.Eval(vals) << std::endl; -} - - - -============================================================================= - - The function string -============================================================================= - - The function string understood by the class is very similar to the C-syntax. - Arithmetic float expressions can be created from float literals, variables -or functions using the following operators in this order of precedence: - - () expressions in parentheses first - -A unary minus - A^B exponentiation (A raised to the power B) - A*B A/B A%B multiplication, division and modulo - A+B A-B addition and subtraction - A=B AB comparison between A and B (result is either 0 or 1) - A&B result is 1 if int(A) and int(B) differ from 0, else 0. - A|B result is 1 if int(A) or int(B) differ from 0, else 0. - - Since the unary minus has higher precedence than any other operator, for - example the following expression is valid: x*-y - Note that the '=' comparison can be inaccurate due to floating point - precision problems (eg. "sqrt(100)=10" probably returns 0, not 1). - - The class supports these functions: - - abs(A) : Absolute value of A. If A is negative, returns -A otherwise - returns A. - acos(A) : Arc-cosine of A. Returns the angle, measured in radians, - whose cosine is A. - acosh(A) : Same as acos() but for hyperbolic cosine. - asin(A) : Arc-sine of A. Returns the angle, measured in radians, whose - sine is A. - asinh(A) : Same as asin() but for hyperbolic sine. - atan(A) : Arc-tangent of (A). Returns the angle, measured in radians, - whose tangent is (A). - atan2(A,B): Arc-tangent of A/B. The two main differences to atan() is - that it will return the right angle depending on the signs of - A and B (atan() can only return values betwen -pi/2 and pi/2), - and that the return value of pi/2 and -pi/2 are possible. - atanh(A) : Same as atan() but for hyperbolic tangent. - ceil(A) : Ceiling of A. Returns the smallest integer greater than A. - Rounds up to the next higher integer. - cos(A) : Cosine of A. Returns the cosine of the angle A, where A is - measured in radians. - cosh(A) : Same as cos() but for hyperbolic cosine. - cot(A) : Cotangent of A (equivalent to 1/tan(A)). - csc(A) : Cosecant of A (equivalent to 1/sin(A)). - eval(...) : This a recursive call to the function to be evaluated. The - number of parameters must be the same as the number of parameters - taken by the function. Usually called inside if() to avoid - infinite recursion. - exp(A) : Exponential of A. Returns the value of e raised to the power - A where e is the base of the natural logarithm, i.e. the - non-repeating value approximately equal to 2.71828182846. - floor(A) : Floor of A. Returns the largest integer less than A. Rounds - down to the next lower integer. - if(A,B,C) : If int(A) differs from 0, the return value of this function is B, - else C. Only the parameter which needs to be evaluated is - evaluated, the other parameter is skipped; this makes it safe to - use eval() in them. - int(A) : Rounds A to the closest integer. 0.5 is rounded to 1. - log(A) : Natural (base e) logarithm of A. - log10(A) : Base 10 logarithm of A. - max(A,B) : If A>B, the result is A, else B. - min(A,B) : If A1, n*eval(n-1), 1)" - - Note that a recursive call has some overhead, which makes it a bit slower - than any other operation. It may be a good idea to avoid recursive functions - in very time-critical applications. Recursion also takes some memory, so - extremely deep recursions should be avoided (eg. millions of nested recursive - calls). - - Also note that the if() function is the only place where making a recursive - call is safe. In any other place it will cause an infinite recursion (which - will make the program eventually run out of memory). If this is something - which should be avoided, it may be a good idea to disable the eval() - function completely. - The eval() function can be disabled with the DISABLE_EVAL precompiler - constant (see the beginning of fparser.cc). - - -============================================================================= - - Contacting the author -============================================================================= - - Any comments, bug reports, etc. should be sent to warp@iki.fi - - -============================================================================= - - The algorithm used in the library -============================================================================= - - The whole idea behind the algorithm is to convert the regular infix -format (the regular syntax for mathematical operations in most languages, -like C and the input of the library) to postfix format. The postfix format -is also called stack arithmetic since an expression in postfix format -can be evaluated using a stack and operating with the top of the stack. - - For example: - - infix postfix - 2+3 2 3 + - 1+2+3 1 2 + 3 + - 5*2+8/2 5 2 * 8 2 / + - (5+9)*3 5 9 + 3 * - - The postfix notation should be read in this way: - - Let's take for example the expression: 5 2 * 8 2 / + - - Put 5 on the stack - - Put 2 on the stack - - Multiply the two values on the top of the stack and put the result on - the stack (removing the two old values) - - Put 8 on the stack - - Put 2 on the stack - - Divide the two values on the top of the stack - - Add the two values on the top of the stack (which are in this case - the result of 5*2 and 8/2, that is, 10 and 4). - - At the end there's only one value in the stack, and that value is the -result of the expression. - - Why stack arithmetic? - - The last example above can give you a hint. - In infix format operators have precedence and we have to use parentheses to -group operations with lower precedence to be calculated before operations -with higher precedence. - This causes a problem when evaluating an infix expression, specially -when converting it to byte code. For example in this kind of expression: - (x+1)/(y+2) -we have to calculate first the two additions before we can calculate the -division. We have to also keep counting parentheses, since there can be -a countless amount of nested parentheses. This usually means that you -have to do some type of recursion. - - The most simple and efficient way of calculating this is to convert it -to postfix notation. - The postfix notation has the advantage that you can make all operations -in a straightforward way. You just evaluate the expression from left to -right, applying each operation directly and that's it. There are no -parentheses to worry about. You don't need recursion anywhere. - You have to keep a stack, of course, but that's extremely easily done. -Also you just operate with the top of the stack, which makes it very easy. -You never have to go deeper than 2 items in the stack. - And even better: Evaluating an expression in postfix format is never -slower than in infix format. All the contrary, in many cases it's a lot -faster (eg. because all parentheses are optimized away). - The above example could be expressed in postfix format: - x 1 + y 2 + / - - The good thing about the postfix notation is also the fact that it can -be extremely easily expressed in bytecode form. - You only need a byte value for each operation, for each variable and -to push a constant to the stack. - Then you can interpret this bytecode straightforwardly. You just interpret -it byte by byte, from the beginning to the end. You never have to go back, -make loops or anything. - - This is what makes byte-coded stack arithmetic so fast. - - - -============================================================================= - Usage license: -============================================================================= - -Copyright © 2003 Juha Nieminen, Joel Yliluoma - - 1.
