You might also enjoy looking at Gorilla REPL [1], which has an easily extensible renderer [2] for just this sort of thing. Disclosure: I'm one of its authors! Jony [1] http://gorilla-repl.org [2] http://vimeo.com/89532785 On Sunday, 13 July 2014 18:51:40 UTC+1, Sam Raker wrote: > > I'm workin

Re: When to prefer keywords as functions?

One thing to note is that while it's true "keywords can be used as functions" they can only really do one thing, which is get values from maps. That is to say, the keyword-function :foo is equivalent to the function #(get % foo). The function :foo has no relationship with the function foo, if i

Re: Tools.nrepl middleware-dependency sorting issues

I'm not sure it's relevant, but one thing that caught me out is that the "interruptible-eval" middleware has a hard dependency on the "pr-values" middleware (i.e. it depends on #'clojure.tools.nrepl.middleware.pr-values/pr-values). I found this caused trouble when I was trying to insert my own

Re: lein uberjar much faster as lein run

I recall reading that `lein run` uses JVM options optimised for startup time, not performance - as it's intended for use in development, not production. I can't seem to find where I read that though ... Jony -- You received this message because you are subscribed to the Google Groups "Clojure

Re: [ANN] Gorilla REPL 0.2.0 - all new extensible renderer

Thanks for the kind words chaps - glad you like it! @Steve Are you sure your Leiningen is up to date? I've only seen this problem when accidentally trying to run Gorilla with Lein 1.7 (as Debian seems to have that version as its default install). @Andrew Probably not what you're looking for, bu

Re: Online Gorilla REPL worksheet viewer

Hi Paul, the viewer code is pretty much all in the main project, as it shares much of its code with the editor. You can run your own instance of the viewer just by serving up the (static) files in the 'resources/public' directory of the gorilla-repl jar - no server side code is needed - and vi

Re: Leiningen: referring to another project on local disc

Or, you could make a directory called 'checkouts' inside the poker project directory, and put a symlink in there to the testgen project directory. Lein will look in the checkouts directory before it looks to any repository. See here: https://github.com/technomancy/leiningen/blob/master/doc/TUT

Online Gorilla REPL worksheet viewer

Hi folks, I've got a very simple online viewer for Gorilla REPL worksheets going here: http://gorilla-repl.org/viewer.html It's free, with no registration or other burdensome business. You use it by uploading your worksheet to GitHub, either as part of a project, or to a Gist, and then const

Thanks all :) @A. Webb: I knew it must be something dopey, thanks for the advice! @Lee That is indeed exactly what I'm trying to do, and that method is much more elegant and straightforward. In fact, precisely what I'm trying to do is write some notes on symbolic regression for some students, w

Function from a symbolic expression

Hi all, I've gotten myself stuck with what is probably a simple question, and wonder if someone can advise. What I want to be able to do is to take a symbolic expression, like '(+ 1 x) say, and turn it in to a function programmatically, so that I can call something like: (def ex '(+ 1 x)) (de

[ANN] Gorilla REPL 0.2.0 - all new extensible renderer

Hi all, I'm happy to announce a new release of Gorilla REPL. The number one comment I got from people on the original release was that it looked good, but they'd like to see it extended to some library or other. Jeff Rose hit the nail on the head with: "Being able to render values of differen
