Scripts > Class elements and c++ instructions


While parsing the input simultaneous the recognized sections of text can be processed. Before and after each step of recognition semantic actions are executed. A semantic action consists of c++ instructions.

In contrast to programming languages, which have to translate instruction to binary code understandable for the computer and then to build a new executable from these binaries, in the TextTransformer a lot of instructions can directly be executed, that means: they are interpretable.


The integrated interpreter of the TextTransformer masters


1. A sub set of the instructions of the programming language c++


2. Several functions, which are created specially for the use in TETRA


3. Formatting instructions


4. Several instructions, to access the actual state of the parser


5. User defined functions and variables (class elements)
