In general: more optimizations are + now applied to the bytecode. The downside is that callback Functions + can no longer be flagged as non-optimizable. (The flag is still present + but ignored) This is necessary since the optimizer had to call the + functions in order to precalculate the result (see Bugfixes). These calls + posed a problems for callback functions with side effects and if-then-else + clauses in general since they undermined the shortcut evaluation prinziple. + + Bugfixes: + * Infix operators where not properly detected in the presence of a constant + name starting with an underscore which is a valid character for infix + operators too (i.e. "-_pi"). + * Issue 3463353: Callback functions are called twice during the first call to eval. + * Issue 3447007: GetUsedVar unnecessaryly executes callback functions. + + +Rev 2.1.0: 19.11.2011 +--------------------- + New feature: + * Function atan2 added + + Bugfixes: + * Issue 3438380: Changed behaviour of tellg with GCC >4.6 led to failures + in value detection callbacks. + * Issue 3438715: only "double" is a valid MUP_BASETYPE + MUP_BASETYPE can now be any of: + float, + double, + long double, + short, + unsigned short, + unsigned int, + long, + unsigned long. + Previousely only floating point types were allowed. + Using "int" is still not allowed! + * Compiler issues with GCC 4.6 fixed + * Custom value recognition callbacks added with AddValIdent had lower + priority than built in functions. This was causing problems with + hex value recognition since detection of non hex values had priority + over the detection of hex values. The "0" in the hex prefix "0x" would + be read as a separate non-hex number leaving the rest of the expression + unparseable. + +Rev 2.0.0: 04.09.2011 +--------------------- +This release introduces a new version numbering scheme in order to make +future changes in the ABI apparent to users of the library. The number is +now based on the SONAME property as used by GNU/Linux. + + Changes: + * Beginning with this version all version numbers will be SONAME compliant + * Project files for MSVC2010 added + * Project files for MSVC2003 removed + * Bytecode parsing engine cleaned up and rewritten + * Retrieving all results of expressions made up of comma separate + subexpressions is now possible with a new Eval overload. + * Callback functions with fixed number of arguments can now have up to 10 + Parameters (previous limit was 5) + + New features: + * ternary if-then-else operator added (C++ like; "(...) ? ... : ..." ) + * new intrinsic binary operators: "&&", "||" (logical and, or) + * A new bulkmode allows submitting large arrays as variables to compute large + numbers of expressions with a single call. This can drastically improve + parsing performance when interfacing the library from managed languages like + C#. (It doesn't bring any performance benefit for C++ users though...) + + Removed features: + * intrinsic "and", "or" and "xor" operators have been removed. I'd like to let + users the freedom of defining them on their own versions (either as logical or bitwise + operators). + * Implementation for complex numbers removed. This was merely a hack. If you + need complex numbers try muParserX which provides native support for them. + (see: http://beltoforion.de/muparserx/math_expression_parser_en.html) + + Bugfixes: + * User defined operators could collide with built in operators that entirely + contained their identifier. i.e. user defined "&" would not work with the built + in "&&" operator since the user defined operator was detected with a higher + priority resulting in a syntax error. + * Detection of unknown variables did not work properly in case a postfix operator + was defined which was part of the undefined variable. + i.e. If a postfix operator "m" was defined expressions like "multi*1.0" did + not detect "multi" as an undefined variable. + (Reference: http://sourceforge.net/tracker/index.php?func=detail&aid=3343891&group_id=137191&atid=737979) + * Postfix operators sharing the first few characters were causing bogus parsing exception. + (Reference: https://sourceforge.net/tracker/?func=detail&aid=3358571&group_id=137191&atid=737979) + +Rev 1.34: 04.09.2010 +-------------------- + Changes: + * The prefix needed for parsing hex values is now "0x" and no longer "$". + * AddValIdent reintroduced into the DLL interface + + New features: + * The associativity of binary operators can now be changed. The pow operator + is now right associative. (This is what Mathematica is using) + * Seperator can now be used outside of functions. This allows compound + expressions like: + "a=10,b=20,c=a*b" The last "argument" will be taken as the return value + + Bugfixes: + * The copy constructor did not copy binary operator definitions. Those were lost + in the copied parser instance. + * Mixing special characters and alphabetic characters in binary operator names + led to inconsistent parsing behaviour when parsing expressions like "a ++ b" + and "a++b" when "++" is defined as a binary operator. Binary operators must + now consist entirely of special characters or of alphabetic ones. + (original bug report: https://sourceforge.net/projects/muparser/forums/forum/462843/topic/3696881/index/page/1) + * User defined operators were not exactly handled like built in operators. This + led to inconsistencies in expression evaluation when using them. The results + differed due to slightly different precedence rules. + * Using empty string arguments ("") would cause a crash of muParser + + +Rev 1.32: 29.01.2010 +-------------------- + + Changes: + * "example3" renamed to "example2" + * Project/Makefiles files are now provided for: + - msvc2003 + - msvc2005 + - msvc2008 + - watcom (makefile) + - mingw (makefile) + - bcc (makefile) + * Project files for borland cpp builder were removed + + + New features: + * Added function returning muparsers version number + * Added function for resetting the locale + + + Bugfixes: + * Changes example1 in order to fix issues with irritating memory leak reports. + Added conditional code for memory leak detection with MSVC in example1. + (see: http://www.codeproject.com/KB/recipes/FastMathParser.aspx?msg=3286367#xx3286367xx) + * Fixed some warnings for gcc + + + +Rev 1.31cp: 15.01.2010 (Maintainance release for CodeProject) +---------------------- + + Changes: + * Archive structure changed + * C# wrapper added + * Fixed issued that prevented compiling with VS2010 Beta2 + + +Rev 1.30: 09.06.2008 +-------------------- + + Changes: + * Epsilon of the numerical differentiation algorithm changed to allow greater accuracy. + + New features: + * Setting thousands separator and decimal separator is now possible + + Bugfixes: + * The dll interface did not provide a callback for functions without any arguments. + + +Rev 1.29: Januar 2008 +--------------------- + + Unrelease Version available only via SVN. + + +Rev 1.28: 02. July, 2007 +--------------------------- + + Library changes: + * Interface for the dynamic library changed and extended to create an interface + using pure C functions only. + * mupInit() removed + + Build system: + * MSVC7 Project files removed in favor of MSVC8 + + Bugfixes: + * The dynamic library did not build on other systems than linux due to a misplaced + preprocessor definition.

February, 2006 +--------------------------- + + Build system: (special thanks to Francesco Montorsi for implementing it!) + * created a bakefile-based build system which adds support for the following win32 compilers: + -> MS visual C++ (6 and .NET) + -> BorlandC++ (5 or greater) + -> Mingw32 (tested with gcc 3.2) + -> Watcom (not tested) + and for GCC on Unix (using a standard autoconf's configure script). + + Compatibility improvements: + * fixed some small warnings when using -Wall with GCC on Unix + * added inclusion guards for win32-specific portions of code + * added fixes that remove compiler warnings on Intel C++ and the Solaris C++ compiler. + + +Rev 1.24: 29. October, 2005 +--------------------------- + +Changes: + + Compatibility improvements: + * parser now works on 64 bit compilers + * (bytecode base datatype can now be changed freely) + + +Rev 1.23: 19. October, 2005 +--------------------------- + +Changes: + + Bugfixes: + * Variable factory examples in Example1.cpp and Example3.cpp contained a subtle bug. + + New features: + * Added a MSVC6 project file and introduced muParserFixes.h in order to make it compile with MSVC6 + + +Rev 1.22: October, 2005 +----------------------- + +Release notes: + +All features of Version 1.22 are similar to Version 1.21. Version 1.22 fixes a compilation issue with +gcc 4.0. In order to fix this issue I rewrote part of the library to remove some unnecessary templates. +This should make the code cleaner. The Borland Project files were removed. If you want to use it +with Borland either use the dll version or create your own project files. I can't support it since I don't +have this compiler at hand. + +Changes: + + Project Changes: + * Borland project files removed + (The code should still compile with BCB but I cant provide you with project files) + + Internal Changes: + * unnecessary template files have been removed: + - new files: muParserError.cpp, muParserTokenReader.cpp, muParserCallback.cpp + - removed Files: muIParserTypes.h + + +Rev 1.2 / 1.21: April, 2005 +--------------------------- + +Release Notes: +First of all the interface has changed so this version is not backwards compatible. +After receiving a couple of questions about it, this version features support for +user defined binary operators. Consequently the built in operators can now be +turned off, thus you can deactivate them and write complete customized parser +subclasses that only contain the functionality you want. Another new feature is +the introduction of callback functions taking string arguments, implicit +generation of variables and the Assignement operator. + + Functionality + * New built in operator: xor; Logical xor. + * New built in operator: Assignement operator; Defining variables in terms of + other variables/constants + * New feature: Strings as arguments for callback functions + * New feature: User defined binary operators + * New feature: ParserInt a class with a sample implementation for + integer numbers. + * New feature: Callbacks to value regognition functions. + + * Removed: all predefined postfix operators have been removed. + * New project file: Now comes with a ready to use windows DLL. + * New project file: Makefile for cygwin now included. + * New example: Example3 shows usage of the DLL. + + Interface changes + * New member function: DefineOprt For adding user defined binary operators. + * New member function: EnableBuiltInOprt(bool) Enables/Disables built in + binary operators. + * New member function: AddValIdent(...) to add callbacks for custom value + recognition functions. + * Removed: SetVar(), SetConst(). + * Renamed: Most interface functions have been renamed + * Changed: The type for multiargument callbacks multfun_type has changed. + It no longer takes a std::vector as input. + + Internal changes + * new class muParserTokenReader.h encapsulates the token identification + and token assignement. + * Internal handling of function callbacks unified as a result the performance + of the bytecode evaluation increased. + + +Rev 1.10 : December 30, 2004 +---------------------------- + +Release Notes: +This version does not contain major new feature compared to V1.07 but its internal structure has +changed significantly. The String parsing routine is slower than the one of V1.07 but bytecode +parsing is equally fast. On the other hand the error messages of V1.09 are more flexible and you +can change its value datatype. It should work on 64-bit systems. For this reason I supply both +versions for download. If you use V1.07 and are happy with it there is no need for updating +your version. + + * New example program: Archive now contains two demo programs: One for standard C++ and one for + managed C++. + * New member function: RemoveVar(...) can be used for removing a single variable from the internal + storage. + * New member function: GetVar() can be used for querying the variable names and pointers of all + variables defined in the parser. + * New member function: GetConst() can be used for querying all defined constants and their values. + * New member function: GetFunDef() can be used for querying all defined functions and the number of + arguments they expect. + * Internal structure changed; hanging base datatype at compile time is now possible. + * Bugfix: Postfix operator parsing could fail in certain cases; This has been fixed now. + * Bugfix: Variable names must will now be tested if they conflict with constant or function names. + * Internal change: Removed most dependencies from the C-string libraries. + * Internal change: Bytecode is now stored in a separate class: ParserByteCode.h + * Internal change: GetUsedVar() does no longer require that variables are defined at time of call. + * Internal change: Error treatment changed. ParserException is no longer derived from + std::runtime_error; Internal treatment of Error messages changed. + * New functions in Parser interface: ValidNameChars(), ValidOprtChars() and ValidPrefixOprtChars() + they are used for defining the charset allowed for variable-, operator- and + function names. + + +Rev 1.09 : November 20, 2004 +---------------------------- + + * New member function: RemoveVar(...) can be used for removing a single variable from the internal + storage. + * Internal structure changed; changing base datatype at compile time is now possible. + * Bug fix: Postfix operator parsing could fail in certain cases; This has been fixed now. + * Internal change: Removed most dependencies from the C-string libraries. + * Internal change: Bytecode is now stored in a seperate class: ParserByteCode.h. + * Internal change: GetUsedVar() does no longer require that variables are defined at time of call. + * Internal change: Error treatment changed. ParserException is no longer derived from + std::runtime_error; Internal treatment of Error messages changed. + * New functions in Parser interface; ValidNameChars(), ValidOprtChars() and ValidPrefixOprtChars() + they are used for defining the charset allowed for variable-, operator- and function names. + + +Rev 1.08 : November, 2004 +------------------------- + + * unpublished; experimental template version with respect to data type and underlying string + type (string <-> widestring). The idea was dropped... + + +Rev 1.07 : September 4 2004 +--------------------------- + + * Improved portability; Changes to make life for MSVC 6 user easier, there are probably still some + issues left. + * Improved portability; Changes in order to allow compiling on BCB. + * New function; value_type Diff(value_type *a_Var, value_type a_fPos) 4th order Differentiation with + respect to a certain variable; added in muParser.h. + + +Rev 1.06 : August 20 2004 +------------------------- + + * Volatile functions added; All overloaded AddFun(...) functions can now take a third parameter + indicating that the function can not be optimized. + * Internal changes: muParserStack.h simplified; refactorings + * Parser is now distributed under the MIT License; all comments changed accordingly. + + +Rev 1.05 : August 20 2004 +------------------------- + + * Variable/constant names will now be checked for invalid characters. + * Querying the names of all variables used in an expression is now possible; new function: GetUsedVar(). + * Disabling bytecode parsing is now possible; new function: EnableByteCode(bool bStat). + * Predefined functions with variable number of arguments added: sum, avg, min, max. + * Unary prefix operators added; new functions: AddPrefixOp(...), ClearPrefixOp(). + * Postfix operator interface names changed; new function names: AddPostfixOp(...), ClearPostfixOp(). + * Hardcoded sign operators removed in favor of prefix operators; bytecode format changed accordingly. + * Internal changes: static array removed in Command code calculation routine; misc. changes. + + +Rev 1.04 : August 16 2004 +------------------------- + + * Support for functions with variable number of arguments added. + * Internal structure changed; new: ParserBase.h, ParserBase.cpp; removed: ParserException.h; + changed: Parser.h, Parser.cpp. + * Bug in the bytecode calculation function fixed (affected the unary minus operator). + * Optimizer can be deactivated; new function: EnableOptimizer(bool bStat). + + +Rev 1.03 : August 10 2004 +------------------------- + + * Support for user-defined unary postfix operators added; new functions: AddPostOp(), InitPostOp(), + ClearPostOp(). + * Minor changes to the bytecode parsing routine. + * User defined functions can now have up to four parameters. + * Performance optimized: simple formula optimization added; (precalculation of constant parts of the + expression). + * Bug fixes: Multi-arg function parameters, constant name lookup and unary minus did not work properly. + + +Rev 1.02 : July 30 2004 +----------------------- + + * Support for user defined constants added; new functions: InitConst(), AddConst(), SetConst(), + ClearConst(). + * Single variables can now be added using AddVar(); you have now the choice of adding them either + one by one or all at the same time using SetVar(const varmap_type &a_vVar). + * Internal handling of variables changed, is now similar to function handling. + * Virtual destructor added; InitFun(), InitConst() are now virtual too thus making it possible to + derive new parsers with a modified set of default functions and constants. + * Support for user defined functions with 2 or 3 parameters added; bytecode format changed to hold + function parameter count. + + +Rev 1.01 : July 23 2004 +----------------------- + + * Support for user defined functions has been added; new functions: AddFun(), ClearFun(), + InitFunctions(). + * Built in constants have been removed; the parser contained undocumented built in + constants pi, e. + There was the possibility of name conflicts with user defined variables. + * Setting multiple variables with SetVar can now be done with a map of names and pointers as the only + argument. For this reason, a new type Parser::varmap_type was added. The old version that took 3 + arguments (array of names, array of pointers, and array length) is now marked as deprecated. + * The names of logarithm functions have changed.
