About LCL_DIR and VCL_DIR:
- The tool must work without Delphi sources too.
- The tool should also work with Delphi packages.
- The tool should also convert Delphi projects, which require packages. A
LCL_DIR is not enough.
The idea is that:
It first scans the project for required packages and searches corresponding
lazarus packages.
Then it loads the needed packages.
Then it scans for search paths and compiler options.
Then it converts each .pas file and does a simple conversion of the .dfm to
.lfm files.
Then it searches for all used classes in the .lfm files and collects all
properties.
Then it finishes the conversion of the .lfm files.
The package stuff, the compiler options and the .lpi parts require so many
parts of the IDE, that it will be quite hard to create a separated
application. That's why I suggest to create instead a package with the
conversion functions. You can write a small application to test the basic
functions, like converting simple Delphi projects.
