MindStream / Articles in English / Code generation. Extracting the specific model and the specific templates to external dictionaries

Original in Russian

The previous series was here – Code generation. Extracting almost everything to external dictionaries.

Now we will extract the specific model and the specific templates to external dictionaries.

The following code stays untouched:

USES

  '
  CodeGen - function to test functionality
  '

USES
 Concrete.ms.model
 // - loads the specific model
;

USES
 CodeDump.ms.dict
 // - the CodeDump.ms.dict is loaded so we can “see” the DumpElement word
;

this.method.addr DumpElement
%REMARK
 '
 - the CodeGen element and its contents are dumped in a standard output device.
   We only do it to debug what we’ve written.
 '

USES
 Generation.ms.dict
 // - in order to load CallGensList
 CommonLang.ms.tpl
 // - loads the specific templates of code generation
;

%REMARK
 '
 The available axiomatic is output to a standard output device.

( Project1 Project2 Project3 )
%REMARK 'Full list of root elements (projects)'
 ( .dump .pas .c++ .h .script )
 %REMARK 'Full list of generators'
  CallGensList
  %REMARK '- launches the list of generators on the model’s “root elements” list'

; // CodeGen

CodeGen

Next we will develop the templates of code generation as target languages.

As for now, the templates of code generation as target languages look as follows:
// CommonLang.ms.tpl
// Code generation templates for “common languages”
