The paper presents an original application, written by authors, which supports writing and edition of source codes in
VHDL language. It is a step towards fully automatic, augmented code writing for photonic and electronic systems, also
systems based on FPGA and/or DSP processors. An implementation is described, based on VEditor. VEditor is a free
license program. Thus, the work presented in this paper supplements and extends this free license. The introduction
characterizes shortly available tools on the market which serve for aiding the design processes of electronic systems in
VHDL. Particular attention was put on plug-ins to the Eclipse environment and Emacs program. There are presented
detailed properties of the written plug-in such as: programming extension conception, and the results of the activities of
formatter, re-factorizer, code hider, and other new additions to the VEditor program.
