Re: ANN: LispIndent, jEdit plugin that indents lisp code

The plugin has been updated to support function argument indenting. It is configurable in the plugin options. Next, I think I will implement "presets". The idea is that each preset corresponds to one language. That way, LispIndent can still be language-independent. Users will also be spared of imp

ANN: LispIndent, jEdit plugin that indents lisp code

Hi, As I were unable to find a way to indent lisp code in jEdit, I decided to write a plugin for this purpose. It's called LispIndent and can be found here: https://github.com/odyssomay/LispIndent Please report if you have any problems! Jonathan -- You received this message because you are su

I agree with Lee. Everything that works in standard clojure should also work in an eval. Jonathan On Mon, Oct 15, 2012 at 8:11 PM, Lee Spector wrote: > On Oct 15, 2012, at 12:51 PM, Alan Malloy wrote: > > > Evaluating function literals is not intended to work; that it works > > for non-closure

File endings proposal for easier cross-compiling

Hi, In my opinion, cross-compiler projects is way too complicated to pull off. When they really shouldn't be. Therefore, I'm proposing the following file ending scheme: .clj - detected by all compilers. In a cross-compiler project, .clj files contains code not specific to the compiler. .cljj - d

Re: Clojure contrib profiler error

clojure.contrib is not supported in clojure versions 1.3+ The reason in this case is that in 1.3+, it is necessary to add ^:dynamic or ^{:dynamic true} in the def form (i.e. to the metadata) for the var to be dynamically changed with bindings. Fixed clojure.contrib.profile: https://gist.github.com

Re: [ANN] Timbre, an all-Clojure logging library

Looks good! As you said, logging is just too damn complicated in java. Suggestion: change timbre/config to a function, seems way nicer to call (timbre/config :current-level :warn) rather than (swap! timbre/config assoc :current-level :warn) Jonathan On Mon, May 28, 2012 at 1:17 PM, Peter Taou

Re: ClojureScript One

When clojurescript first came out (.toString this) (.toString this 3) both of these seems to be a function call, but the first one was transformed to (. this toString) and because there is no way to know if the user meant to call the function "toString" or get the property "toString", it return

[CLJS] Disable name mangling for 'static'

Hi, I want to create a (partially static) server with nodejs and express. I want to be able to write something like the following: (def app (.createServer express)) (.use app (.static express "public")) (.listen app 8080) The problem here is that clojurescript seems to compile the name 'static

It works now, and the result is as expected. In the browser I still get the extra characters however. On Tue, Oct 18, 2011 at 5:04 PM, David Nolen wrote: > Have you rerun the bootstrap script since the Rhino upgrade? > > > On Tue, Oct 18, 2011 at 10:33 AM, Jonathan Fischer Friber
