Hi Symfony users,
I recently began doing some development using the Symfony 1.4
framework, which I have found to be very well designed and helpful.
However, I ran across a problem recently, and would really appreciate
it if someone can help me with it.
There appears to be a missed implementation (or I may have simply
misunderstood the YAML specification), in sfYAML parser, dealing with
multi-lined Flow Sequence declarations. I'm trying to define an array
with:
---
[
apple,
orange,
]
...
As opposed to:
---
[ apple, orange]
...
The multi-line syntax is useful when the array/sequence gets large.
According to the YAML spec, example 7.14, the former seems to be an
allowed expression: http://www.yaml.org/spec/1.2/spec.html#id2790320
Another reference can be found here:
http://en.wikipedia.org/wiki/User:Baxter.brad/Drafts/YAML_Tutorial_and_Style_Guide#Flow_Sequences
However, when I use the sfYAML parser, rev. 32519,
http://svn.symfony-project.com/components/yaml/branches/1.0/lib, it
throws an exception. After some digging, I found that the problem is
caused by line 341, sfYAMLParser.php, where "\n" is used as the
implode glue:
return implode("\n", $data);
This can be fixed by replacing it with a condition check for the glue
character:
$glue = ( $data[0][0] == "[" || $data[0][0] == "{" ) ? "" : "\n";
return implode($glue, $data);
Given that I have very little experience with the Symfony framework,
can someone please kindly let me know if I had simply misunderstood
the syntax?
Thank you for your time!
