Hi Tu,

The reason SRecode needs Semantic is because several of it's features 
depends on information from semantic.  For example, it asks semantic 
where in the buffer you are so it can provide better template choices. 
In addition, many templates depend on input variables calculated from 
the semantic information in the local environment.

I suspect what you really want is to enable/disable combinations of 
different semantic related minor modes only in major modes of your choice.

As in the stack-overflow article you point out, you can allow Semantic 
to init normally in all it's modes, but don't enable those modes via the 
semantic-init-hook, or via semantic-default-submodes, nor via the 
'global-*' version of the mode function.  Instead turn on the mode via 
the non-global function in the mode hook.

For example:

(add-hook 'c-mode-hook 'semantic-idle-summary-mode)

you could also turn all the different semantic modes on by default, but 
turn off some semantic modes in your major-mode hook:

(add-hook emacs-lisp-mode-hook (lambda () (semantic-idle-summary-mode -1))

As for idle-summary-mode, it should be off by default in Emacs Lisp mode 
as it defers to eldoc mode.  I hadn't tried it in common-lisp mode, 
perhaps semantic is forcing eldoc to run in common lisp in an Emacs Lisp 
style..

I hope this helps.
Eric
