Hi!
I\'ve implemented a new lexer for language Structured text. Details description, syntax and other necessary info you can find here - http://en.wikipedia.org/wiki/Structured_text

In attached there is a lexer source file, modified header "Scintilla.h" and modified file for processing Python compiler. I've checked this lexer with scintilla version 3.2.2. Is it possible to include this lexer into future releases of scintilla ?

Fails to build:
..\lexers\LexSTTXT.cxx(155) : error C3861: 'ClassifyfcSTWord': identifier not found
..\lexers\LexSTTXT.cxx(184) : error C3861: 'ClassifyfcSTWord': identifier not found
..\lexers\LexSTTXT.cxx(379) : error C3861: 'ClassifyfcSTWordFoldPoint': identifier not found

In the Scintilla.iface file, there should be '=' between the symbol and value for 'val' lines.

    Error during compilation? If yes, what compiler do you use ?

      Its not an error: its a bug with a repeated expression probably showing that a case was missed.
      
      I check with Visual C++. g++ and Clang. Also run cppcheck and the analyze commands of Visual C++ and Clang.
      
      The file needs a header comment pointing to the License.txt similar to LexPython.cxx.
      
      The name "fcST" does not produce any reasonable hits on Google so appears to be a poor choice.

Strange, but it is, checked previous attached files with Visual Studio 12, Visual C++ 11 version, no warnings.....
