1.2 error message improvement suggestion (missing line #s for some defrecord errors)

[Jason Wolfe]

I'm converting my ~30Kloc project to 1.2 RC1 from a months-old
snapshot, and so far it's been smooth sailing. One thing I've
noticed, however, is that defrecord "parse error" exceptions seem to
be missing line numbers.

The example I ran into was
user> (defrecord foo [bar] :as this )
; Evaluation aborted.

but I think there may be other similar cases.

Loving the great new features, thanks!

I guess the line numbers aren't missing, just ... behaving weirdly.

If I make a file "test.clj" with just one line:

(defrecord foo [bar] :as this)

and start up a fresh, bare REPL:

user=> (use 'test)
java.lang.IllegalArgumentException: Unsupported option(s) - :as
(test.clj:1)
user=> (use 'test)
java.lang.IllegalArgumentException: Unsupported option(s) - :as
(test.clj:2)
user=> (use 'test)
java.lang.IllegalArgumentException: Unsupported option(s) - :as
(test.clj:3)
user=> (use 'test)
....

Line numbers for some other exceptions seem to be behaving properly.

This bug still seems to be present in 1.2 RC2, and is more general
than I previously thought:

jawolfe@[~/Projects/testproj]: cat > src/test.clj


bla
jawolfe@[~/Projects/testproj]: cat > src/test2.clj

(bla)
jawolfe@[~/Projects/testproj]: lein repl
user=> (require 'test)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test.clj:1)
user=> (require 'test)a
java.lang.Exception: Unable to resolve symbol: bla in this context
(test.clj:2)
user=> (require 'test)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test.clj:3)
user=> (require 'test2)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test2.clj:2)
user=> (require 'test2)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test2.clj:2)
user=> (require 'test2)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test2.clj:2)
user=> (require 'test)
java.lang.Exception: Unable to resolve symbol: bla in this context
(test.clj:7)
user=>

I don't think this is a regression -- I can see the same thing in 1.1.

Can you please open a ticket, along with any additional information on which kinds of errors do/do not exhibit the problem?

OK, done.

I don't have more details on what kinds of errors are affected; but, I
believe the wrong line numbers are the REPL line numbers, if that
helps..

Thanks, Jason
