Getting ideas from other editors: Postfix Code Completion

Getting ideas from other editors: Postfix Code Completion

[Tom]

Here's an idea from IDEA for Emacs programming mode developers.
This combination of snippets, completion and transforming
typed expressions seems like a useful convenience feature:

Looks cute, but these are basically local refactorings.

I think I'd prefer invoking them the usual way (with some key
combination, not after typing a dot), but as long as Emacs has no native
refactoring support, the question is moot anyway.

And when it does, implementing something like this would be relatively
trivial.

Cedet has SRecode, which is useful for refactoring.

Looks like a code generation tool. Can you give an example of it being
used for refactoring (i.e. taking an existing piece of code and changing
it according to some rules)?

You can feed it tags from the semantic parser. You can transform the
tags with lisp before you feed them to the generator. This is not like
the Eclipse refactoring tool I saw demoed once.

My own cases are a bit specialized. I do have a more useful example of the code
generation half of the process for generation of C code from lisp for
the Ergodox keyboard firmware.

Actualy, there are 2 parts:
1- "local refactoring".  This should be handled via skeletons/snippets.
2- "postfix completion" which in Emacs would be called "completion of
   abbrev names" where IDEA's examples are abbrevs that start with ".".
