Hi,
Thank you for all answers, as I did my homework (reading overview sent by
Jeff and applying Luca's suggestions), things have improved quite a bit.
Yet there are still some things I'm not fully grasping, so I have more
questions :)
First one is about object created by (om/build ...) - in
If you're using cider (https://github.com/clojure-emacs/cider), there's a
convenience function for controlling the value of *print-length*, including
giving it a default value for new nrepl instances:

there is one then having the programmer work around something like

It's dynamic, so it can be bound for a repl thread!

I would say that there is no sensible default value *including* the
current. Certainly at REPL usage, the current value is probably the
least sensible.

Hi,
I see there are a lot of functions strings, but nothing that allows me to
create a new string with a character replaced at a given index? Am I meant
to use subs and join to do this? It seems a bit long-winded? I wonder why
there isnt a helper function out of the box to do this (or is
There are many ways to do this, these 2 come to mind:
(doto (StringBuilder. abc) (.setCharAt 2 \d))
(apply str (assoc (vec abc) 2 d))
The former is probably a lot faster (uglier too)...

about 1. if that's meant to be portable, yes, not the best indeed, but if
you look at c.c.string/* or even c.c/str, most of the functions use
stringbuilder I think.

Hello everybody,
Given an enormous network of inter-referenced, mutable objects which have
to change in-place driven by events (= the OO system).
Which strategy would you recommend to plug into such a system with Clojure,

these objects are always created on the fly in (render ...) functions. So
if some component disappears from view for some time, it loses its state.
Greetings,
The nuance below took a long time to identify and reduce from a test
failure. Should it be considered a bug?

I guess my point is that if the java function is so good, then why doesnt
the clojure library thinly wrap it, so that your code remains portable
clojure?

Using subs (no need for join) is the way I would go, just define

No. IMO this is not a common operation and should not be in core. If you
need do it a lot, you should not use java string in the first place.
What should be included in core is a transient string, with support for

Is there some like remove, but only removing the first item found?
Not exactly an incredibly hard problem, but with all this clojure

appropriate way is to implement it.

I hate REPLs. I also hate large compile times.
For me the hardest part of the ~5s compile time is not waiting, it's the
watching of the progress of the auto build and waiting until exactly that
moment
