Cursive already allows this with no syntax changes, but it does require reproducing Clojure's type inference in the editor.

Re: Including debugging information for Clojure code

I don't have much time right now, but AFAIK Cursive is the only debugger using JDI - CIDER has a source manipulation debugger. I don't generally have to do anything special to debug, although I use an IntelliJ layer on top of JDI. I can try to check if it's doing anything with that flag. You can al

Re: Splitting Read into 2 steps?

Hi Terje, This is how the parsing works in Cursive. I have a classical lexer/parser split because IntelliJ forces me to do that. That said, I like it that way, and I believe it makes things more flexible. I've been able to make a couple of special-case parsers easily on top of the lexer - I'm abou

Re: Reducing the pain of a clojars outage

I'm travelling at the moment so I don't have time to respond to everything right now, but one thing about the Java 6 issue - IntelliJ won't be fully on Java 8 until IntelliJ 16. This means that Java 6 will be around until a) everyone is on whatever comes after El Capitan (the last OSX to support Ap

Re: [ANN] pex, a powerful PEG parsing library

I'm really impressed by how fast it is out of the box with basically no optimisations. Tatu Saloranta is fanatical about Jackson performance, getting to within 6x on the first attempt is very promising. On 20 November 2015 at 02:43, Ghadi Shayban wrote: > Thanks for taking a look. > > User-level

Re: deprecation warnings?

Sadly Cursive doesn't show this right now - it definitely should, though. Cheers, Colin On 15 October 2015 at 06:55, William la Forge wrote: > *warn-on-deprecated* would be super! :D > > On Wed, Oct 14, 2015 at 1:44 PM, Alex Miller wrote: > >> You might wish to up-vote http://dev.clojure.org/j

Re: Using metadata to specify how calls to a macro should be indented

Unfortunately as tools developers we can't force our indentation preferences on our users, although I'd be fine with it if you convinced everyone to just use two spaces for everything, even though it's not my preferred formatting. Cursive has supported this for ages (copied from Emacs) but I don't

Re: Using metadata to specify how calls to a macro should be indented

This is an interesting proposal, and I like it in general. Everything in Cursive is based on extensions identified by the head form, like this: (style/register-formatting :clojure.core/def :only-indent) (style/register-formatting :clojure.core/defn- :only-indent) (style/register-formatting resolve
