Subject Re: [VOTE] add FreeBuilder to Ambari
Date Wed, 21 Mar 2018 00:20:18 GMT
Let's close this vote:

+1: Balazs Bence Sari, Attila Doroszlai
0: Nate Cole, Jonathan Hurley
-1: Attila Magyar, Robert Levas

Since most developers didn't express any opinion, but would be
affected by the change, I take your silence as a "no".  I'll go ahead
and remove the library from the feature branch, and will not add it on

this thread about requiring an IDE to rely on a third-party tool to generate code.  If something
breaks, we are dead in the water for a while - whether we are waiting for someone to fix the
issue in the tool or whether we need to rewrite code to rip it out.

the generated code (or the meta-code used to generate the actual code), how easy or hard would
it be to access, read, or walk-through that code. Or what if the code generator had a bug
generating code.  We will either need to wait for a fix in the generator or figure out a work-around.

need such a tool?
