| TextTransformer 1.0.0 The newly released product TextTransformer 1.0.0 presents itself after three-year development time as a mature developer tool for the construction of individual programs for the analysis, extraction and transformation of texts. The program offers a visual development environment (IDE) with an integrated parser-generator, a c++ interpreter and a debugger. The range of applications reaches from multiple word substitutions, extractions of information, syntax check, calculations and evaluations of data records up to complete translations from programming languages or developments of scripting languages. Also smaller daily tasks, as the counting of words or the rearrangement of lines of texts are handled fast and easily. TextTransformer is worldwide the only program conceived for both the development and the execution of programs which analyze a text and synthesize a result. For this the parser generator produces recursively descendent parsers with an arbitrary look-ahead possibility. Elementary text sections are recognized by regular expressions and these are connected to a grammar as quasi Meta regular expressions. The TextTransformer isn't restricted to formal languages unlike other parser generators but copes with any text structures; unspecified sections simply can be skipped. To define how the text sections are processed, the designed parser can be extended by semantic actions for a transformation program or a translator. A simple c++ interpreter permits the synthesis of the recognized text sections to a new text or a numeric evaluation of the text contents. The convenient debugging has to be emphasized: the parsers can be tested stepwise or stopped at breaks in the source text or in the grammar. I.e. the professional developer has the possibility of concentrating fully on the development of the grammar of the parser since testing without a previous compiling is possible. The processing step-by-step shows which text section is recognized next by which grammatical branching. But that's not all: grammar tests and a syntax check of the interpreter instructions are carried out automatically and the error position is shown by a mouse click. With the transformation manager or the command line tool ready projects can be applied to file groups. The professional version of the TextTransformer can export a ready transformation program even as a c++ code, which can be included into other software products. TextTransformer 1.0.0 has a comfortable user interface with syntax highlighting and immediate localization of errors. The rule repository is organized like a database, where scripts with definitions for tokens, productions, and class methods can be inserted, deleted or changed. A detailed context sensitive help, a tutorial and various wizards help the user with words and deeds. write your comments about the article :: © 2005 Computing News :: home page |
