Hey, thanks & yes, there seems to be an issue with their syntax highlighter taking quite a while to process the dozens of code blocks on that page. Just give it a few seconds until the page has finished loading before you start scrolling... Will check with the site owners what can be done. On 29 D

How to debug this trace involving Korma

The first lines of the trace says: Failure to execute query with SQL: SELECT "GUESTBOOK" .* FROM "GUESTBOOK" :: [] JdbcSQLException: Message: Table "GUESTBOOK" not found; SQL statement SELECT "GUESTBOOK".* FROM "GUESTBOOK" ... I see that there is a "create-guestbook-table" in schema.clj (defn

No PDF version, but in the coming weeks we will put up a Git repo with the original markdown sources & examples, you can build a PDF from those. For now, couldn't you just print that page to a PDF file, no? On 29 December 2013 11:42, Zeynel wrote: > I like it very much. Is there a pdf version? >

Re: protocols and overloading

Not mentioned in Cedric's post are two other important things: Protocols can be extended to existing types. For example: (defprotocol IType (type-as-string [x])) (extend-protocol IType String (type-as-string [x] "string") Integer (type-as-string [x] "integer")) => (type-as-string 42)

Re: Why is "add-watch" still in alpha?

Actually, one simple way to use core.async to asynchronously watch a future or a promise, or *any* other blocking-derefable thingy, for delivery, is just to throw a (thread (do-something-with @thingy)) in your code somewhere. The thread will block until the thingy is ready, and then do whatever. Me

Reading that tutorial, it looks like it expects you to call (create-tables) manually via the REPL. On Sun, Dec 29, 2013 at 3:47 AM, Zeynel wrote: > The first lines of the trace says: > > Failure to execute query with SQL: > > SELECT "GUESTBOOK" .* FROM "GUESTBOOK" :: [] > JdbcSQLException: > Mess

Re: protocols and overloading

That must have been a long time ago? That problem was solved well before I left the C++ committee in '99 and gcc was normally pretty good at tracking the emerging standard at the time... But, yes, the template compilation model and it's impact on linking modules that specialized the same template

Re: protocols and overloading

Yeah, it was sometime in the 90s. The only workaround I could think of was maybe to create a single compilation unit for template use, and there derive a trivial subclass of each used template specialization, then use that subclass elsewhere in lieu of the template. Needless to say, not a solution

There are at least some keyboard shortcuts you should be familiar with for loading / compiling namespaces. Look a the "Using the REPL" section of this: http://clojure-doc.org/articles/tutorials/emacs.html On Sat, Dec 28, 2013 at 7:38 PM, larry google groups < lawrencecloj...@gmail.com> wrote: >
