[ruote:2256] Get error message after ruote fresh install

[Christophe Malaurie]

Hi John
just installed ruote-2.1.9 (looks great that's why I give it a try),
running the ruote_quickstart.rb and bang...does no display the pretty
message about Alice but instead ....nothing. So far I identified a
kind of error message (see below) when inputing the file into an irb
session.
Tried to increase stack size on the system (ulimit -s xxxx), no effect
except harming the system if I define a stack too high...
I'm running ruby ------ > 1.8.7 (2008-08-11 patchlevel 72) [x86_64-
linux].
and downloaded the soft using rubygems, no problem.

Any idea might save my day.
Many thanks in advance
Cheers
Christophe

Hello Christophe,

I just tried with ruby 1.8.7 (2008-08-11 patchlevel 72)
[i686-darwin10.2.0] and couldn't reproduce the error (works for me).

The "stack level too deep" message is a symptom of an infinite
recursion, ulimit will not help.

Could you please run with

ruby ruote_quickstart.rb -d

and paste the resulting stack trace here ?


Thanks in advance,

Hello,

could you please install the gem "yajl-ruby" and try again ?

I tried with :

- "json" : same error as you
- "json_pure" : works
- "yajl-ruby": works

I will now try with a more recent ruby and those 3 gems...

[Christophe Malaurie]

oops working. Saw the line about yajl-ruby in the "ruote quickstart" web page but did not pay attention to it, except for the JSON gem that I had to install apart.


Cheers and many thanks
Christophe

Great.

it's interesting, json 1.4.3 exposes the issue, but json 1.2.4
(previous generation) works fine. I will try to fill a bug report for
the json gem people.

Thanks,

[Christophe Malaurie]

Yep, kind of thing that could stop people using ruote when it is clearly not a ruote issue.
Is there a way I can get all ruote classes definition (methods and attributes) ? I red with a lot of interest the Guide pages, which contain a lot of information already, but probably not exhaustive.
Many ty again for quick intervention
Cheers
