To accelerate inital development use of already existed tools as Delphi IDE is needed. Although main focus is to mimic sucessfull product like Delphi IDE it is good to achieve independency in future. This means no need to use any third party tools. To fulfill such goal we need to create self-compiled pascal compiler. This is also useful for transfer to other platforms.
Self-compiler should support basic subset of pascal language. It could serve as jumping board for implementation of fully featured compiler.
