Hello Dmytro,
I am sure you know, but I will mention this anyway, just in case:
Please note that the format of the .tcNM file is undocumented and can be changed in future versions of TestComplete. In this case, you will need to rewrite your parser.
Another difficulty with the approach you are trying to implement is the fact that a name mapping tree of a TestComplete project can change. It can be modified, for example, from the TestComplete GUI. Additionally, TestComplete can automatically add new elements to the name mapping tree while recording a test. Every time the name mapping tree is changed, you will need to recreate the code completion information.
