Do you want put script features in your application? Use TatPascalScripter component.

With TatPascalScripter component you can add script capability to your applications. Your end-user can write their own scripts, and your application will become much more flexible..

Main features:
- Access any Delphi object in script, including properties and methods!
- Supports try..except and try..finally blocks in script
- Allows reading/writing of Delphi variables and constants in script
- Allows access (reading/writing) script variables from Delphi code
- You can build (from Delphi code) your own classes, with properties and methods, to be used in script
- Most of Delphi system procedures (conversion, date, formatting, string-manipulation) are already included (IntToStr, FormatDateTime, Copy, Delete, etc.)
- You can add your own custom functions, using AddFunction method
- You can save/load compiled code, so you don't need to recompile source code every time you want to execute it

The CronJob component is the thread-based alarm implementation for Delphi/BCB which acts like cronjob utility in Unix. The component produces periodical OnAlert events by schedule specified in CRON format (actually it uses extended CRON format with new "seconds" field, to let the event to be triggered even every second). To specify the moments when the component should trigger the OnAlert event, the component uses the CRON format (all who worked in Unix must be aware about this utility, this is daemon of scheduled, periodically executed tasks). The authors of CronJob component has very liked an idea of describing the periodical events of any complexity, tiered to astronomical time, in simple text string. We have used slightly modified CRON format, added seconds field and altered the rules of describing the lists of numbers. The package includes 2 bonus components: * AccurateTimer -- thread-based timer which periodically triggers the OnTimer events by specified Interval, but unlike standard TTimer, which based on Win32API and thus loses timer messages on high application overload, this timer runs in the separate thread and accurately triggers each OnTimer event at right time. It also allows to specify the Interval with higher precision (less than 55msec, limited in Win9x) and does not dependent to the system-wide limitations.) * AwayTimer -- monitors user activity and increase its time counter when keyboard and mouse are inactive (user distracted from PC or goes away). Also it triggers special event when system is about to start the screensaver, or after some defined period of user inactivity.

Expression parser 3.1 is a library of components, that evaluates Pascal like scripts at run time. It is not an interpretator, but is a quasi compiler, so it works fast. Features:
  • user defined functions and aliases;
  • supports: if...then..else...;for...:=... to/downto ... do ;; repeat...until...;
  • try finally end; try except end; raising exceptions;
  • class creating, referencing any published property of any class;
  • and more than 800 registered public methods and properties of more than 100 useful Delphi VCL classes;
  • creating and referencing OLE automation objects;
  • links directly in a script to a runtime components, that can be also on a data module;
  • links to any runtime function or class method;
  • calling user defined scripts from the program;
  • executing a script generated script;
  • variables, can be a value, expression, DBField or a link to a runtime var;
  • syntax checking of the scripts, checks also for using a valid variables, functions and arguments;
  • request for used variables, by a given script, that need initialization;
  • on event evaluated functions and variables;
  • supports integer, hex, FP, boolean, date string and variant type constants;
  • design time editors for variables and functions, that can be loaded and saved in INI file;
  • special links of dependences, tracks the changes in related objects;
  • more than 200 build in functions;
  • enhance error handling;
  • full help and demo;
You will feel the Expression parser as a real extention of your favourite compiler at runtime.

Expandable formula parser. Can handle variables. When the parser needs the value of a variable, it creates an event to get it. Very fast if using the same formula with different values for variables, because it works in two steps: parsing to a tree structure and calculate. Different priorities for operators. Unary (exampe: sin) and binary (example: +) operators. List of operators is easy expandable to custom problem. Demo application. Source code on purchase.

The TKAParser component is an expression parser, calculator and spread sheet engine. It can (1) Evaluate mathematical and string expressions that contain numbers, predefined variables and formulas. A mathematical expression may have any commonly used math functions. A string expression may have any commonly used string function. (2) Transparently track formula / variable dependencies. Consequently, the parser needs to re-evaluates a formula only when the value of a dependent variable changes, a feature that enables it to perform hundreds of complex expression evaluations every second. A caching mechanism further optimizes expression evaluation making the parser#well# Kick Ass! · Work with any number of user defined functions. (3) Gracefully handle undefined variables by assigning default user defined value

This Package implements an Artifical Neuronal Network (ANN), which is based on a Backpropagtion algorithm. Empower your Delphi or C++ Builder application with A R T I F I C A L I N T E L L I G E N C E !!! Have a look at the included demo first, if you don't know the power of ANN. The demo illustrate an easy way to implement a simple OCR-Solution with the Component. The demo is included as an Exe-File. No setup-procedure is necessary to run the DEMO. Limitation to the Trial-Version: Full functional, but each layer of the ANN is limited to max. 6 Neurons.

The RapidEvaluator Delphi component is a real COMPILER of the mathematical expressions (formulas), such as "SIN(0.5)+COS(x)*2". It checks the expression syntax and generates the real machine code for evaluating given formula. The code generated is optimized to use FPU in order to achieve the maximal speed of calculations: it's even up to 2 TIMES FASTER THAN DELPHI'S 32-bit code. To satisfy your personal needs you can add external user-defined variables and functions in addition to built-in ones. Use RapidEvaluator to calculate formulas that is unknown at the stage of program compilation, for example to plot and tabulate functions, to make numerical computations and so on. The equation plotting demo program (project+EXE) included.
