Hi,
Two weeks ago I showed Erlide to one guy who has never used it before (he's
developing some big project in Erlang). He tried it and liked it:) However he
has some problems while debugging. Here are his emails:
-----------------------------------------
I gave erl-ide a good go and after a while got it working!!
It always gives me this odd error on my erlang node running in my Terminal app
on my mac, though its not a problem as the code all works fine — breakpoints
and all!
=ERROR REPORT==== 17-Sep-2010::17:14:03 ===
Error in process <0.732.0> on node 'ejabb...@localhost' with exit value:
{badarg,[{erlang,register,[erlide_builder,<0.734.0>]},{erlide_batch,start,2},{erlide_kernel_common,'-init/3-fun-1-',3}]}
=ERROR REPORT==== 17-Sep-2010::17:14:03 ===
Error in process <0.738.0> on node 'ejabb...@localhost' with exit value:

-----------------------------------------
Yes i have been giving erlide a good go and it mostly works. The main problem i
was having is that my erlang code that connects to the "cassandra project"
datastore over the "thrift" interface works perfectly when i run it directly on
my erlang node in the mac terminal but when i connect into it with erlide (by
adding the node name and correct cookie) my code all works fine (and i can
debug it ) until it connects to the Cassandra Project and then crashes with
loads and loads of written out onto the console. Its not a huge problem as i
can run lots of my code with out connecting it to the db but its a bit of a
pain… maybe if i don't run my erlang node in the console but instead tell
erlide to run its own erlang node then it wont have that problem. The only
other question, do you know where the final output of the called function thats
debugged actually goes? as in if i do my on of my test
"example_calls:read_doc_xml_back()." in the terminal it displays lots of
output, but when debugging in erlide it seems to get lost? maybe its logged
somewhere… il have a look!
-----------------------------------------
ok cool i fixed my problem!!
i still get this random junk on my console every time i debug :
=ERROR REPORT==== 30-Sep-2010::00:51:19 ===
Error in process <0.747.0> on node 'ejabb...@localhost' with exit value:
{badarg,[{erlang,register,[erlide_builder,<0.749.0>]},{erlide_batch,start,2},{erlide_kernel_common,'-init/3-fun-1-',3}]}
=ERROR REPORT==== 30-Sep-2010::00:51:19 ===
Error in process <0.753.0> on node 'ejabb...@localhost' with exit value:
{badarg,[{erlang,register,[erlide_scanner_listener,<0.754.0>]},{erlide_scanner_listener,start,0},{erlide_kernel_ide,'-init/0-fun-0-',0}]}
& i have no idea what it means, but it does not effect my code. The way i got
it to work with my cassandra project code was to remove all the Thrift code
(the stuff that talks directly to the Cassandra Project DB, not my code ( its a
RPC serialisation thing) ) from my erlide project and compile that stuff only
in the console node and then it works fine
The only slightly odd problem is when using erlide as a text editor (something
i don't currently plan to do) it pauses for a few seconds every time i type
something that matches an otp / erlang module (eg i type io:format and it locks
up for a few seconds) i guess its trying to look up documentation and failing
so il look in to that. but it is great, i now have a debugger that works soooo
much better than the inbuilt one!
