Helm (and?) or Icicles (possibly using Evil)

[Hans BKK]

I'm looking feedback on these from those (perhaps few?) that have actually 
become somewhat familiar with both. Since EmacsWiki has so much information on 
Icicles (thanks Drew!) there isn't any need to give an overview/run-through on 
that package, but I haven't seen so much on Helm, just a lot of side-mentions 
on how fantastic it is from people whose opinion would seem to carry a lot of 
weight.

For example, does Helm actually help you learn how to use regexp?

Has anyone tried running both together? or is the overlap so great they 
interfere with each other as with icicles and ido?

My current context is facilitating exploring the "self-documentation" aspect of 
emacs, searching/browsing/jumping between info docs and other sources of help 
docs and the relevant source code.

I also plan to use emacs straight off for org-mode, shell usage and files 
management. Actual coding myself will come later, but is of course very 
relevant. Mostly web dev to start, but I want to get to know Python to start 
with and then Haskell, and plan to use pandoc to convert 
language/framework-specific docs to gnu info wherever possible, and to try to 
make my own code self-documenting as with elisp.

Does Helm have any support for creating info "books" as does icicles?

Drew, do you happen to know if your "Help Plus" libs are compatible/helpful 
with Helm's approach?


It's also possible I'll be learning emacs editing in evil mode, except in modes 
where there are still conflicts (apparently few these days), so feedback on 
that aspect is also welcome, apparently Helm's fine there.

I've stuck with del.icio.us since beta, over 20K bookmarks there, so Helm's 
support there as a platform for creating a DAG tree from that (self-documenting 
brain activity) is a tempting little project:
