require 'yaml' and you can use YAML by syck.

= History
#2340 Removing YAML/Syck.
http://redmine.ruby-lang.org/issues/show/2340

After imported psych, it is found that test-all conflicts.
To avoid this, yamler is introduced.
By yamler people can switch syck or psych (default is syck).

= Current
There is 3 element:

• lib/yaml.rb
• ext/syck
• ext/psych

= Q&A
Why psych is bundled:

• To review psych

Why psych is not default:

• it is not confirmed that it can be default in 1.9.2
• it has some incompatibilities showed following.

Why syck is still bundled:

• for machines which libyaml is not installed
• for Windows

Incompatibilities are following, can you explain why it can't compatible, Aaron?

Why psych is not default:

• it is not confirmed that it can be default in 1.9.2

You wrote that "It's decided by Yugui." at [ruby-core:28828].
Didn't it mean to make psych the default YAML engine?

First of all, people want compatibility.
Although Ruby sometimes breaks compatibility, it is important.
We should keep compability until it has enough reason.

Yes! Many of these methods are exposing implementation specific details
for syck. For example, the "detect_implicit" method detects whether a
YAML string is an implicit or explicit string. "try_implicit" which
attempts to use "detect_implicit". "object_maker" calls allocate on
a class and sets instance variables based on a hash. These are clearly
methods which should never be exposed as a public API.

An API is implementation specific is not enough reason.
Implementation can return some value as if it works.
YAML.detect_implicit seems such one.

If an API is depend on syck implementation and hard to emulate,
such API can be removed.
It will trouble some users and it is sorry, but it is unavoidable.

Other methods are deprecated because they are simply duplicates. For
example, YAML.load_documents and YAML.each_document do exactly the same thing.
YAML.each_node and YAML.parse_documents do exactly the same thing.

Duplication is not enough reason to break compatibility.

Yes, your preference should be respect.
You can remove them with some migrating process.

Usual Ruby's process of removing API is:

• mark the API as deprecated
• release some versions
• remove it

On top of that, most of these methods are untested, which makes writing
100% compatible software impossible. All of these methods could
be added to Psych, but it wouldn't be guaranteed that they work the same
way as Syck.

Of course 100% is impossible.
What we need is almost compatible.
"almost" means what people use.

I understood from [ruby-core:28749], that Psych didn't need to have full
compatibility. The best way I could think to warn users and maintain
compatibility is to default to the old parser and let users choose to
use the new one.

If psych doesn't have enough compatibility to replace in 1.9.2,
we need some migration path.

I am happy to add most of these to Psych, if Psych is going to be the
default parser. I do not want to support these methods long term
though. Please give me a clear direction, and I will make it happen.

If psych has enough compatibility, it can be a default parser in 1.9.2.
As far as I know, YAML.quick_emit breaks some applications like RubyGems.

Yeah, what is "enough compatibility" is the problem.
I think, Rails and its dependency can run can be a test.

Issue #3112 has been updated by Usaku NAKAMURA.

Why psych is not default:

• it is not confirmed that it can be default in 1.9.2

You wrote that "It's decided by Yugui." at [ruby-core:28828].
Didn't it mean to make psych the default YAML engine?

What I wanted to say is the direction replacing syck with psych is
already decided.
When it will be done is not intended; 1.9.2 or 1.9.3 or later.

Sorry for misleading.

I found Aaron added YAML.quick_emit to Psych, thank.

So I tried test-all with setting psych as default yaml impl as following:

Some of the Syck YAML tests (like test_spec_application_family and
test_spec_url_escaping) contain invalid YAML, so Psych will raise an
exception. Do diff test/yaml/test_yaml.rb test/psych/test_yaml.rb to
see the differences.

Yeah, I know some of them are intended.
I want to confirm taht all of them are from invalid YAML.

I will make test/yaml/* use the syck engine.

OK, it may have to move to test/syck.

I can't run make test-all on Snow Leopard because of the problem I
mentioned in [ruby-core:29087]. I will try on linux.

Can you make a ticket in Redmine for [ruby-core:29087]?

For workaround you can run test-all like following:
make RUBYOPT=-w TESTS='-v -x "test/drb|test/socket"' test-all

I'm not sure. I've applied this to trunk with Eric's permission.

Won't the bundled minitest will only be available after install?

Ah, yes, so this can be a bug of Gem's load path.
Also note that this can be avoided by install before test-all.

This is from the difference of loaded libraries between syck and psych.
So this is considered as compatibility problem and this is fixed by psych.

Example is following but where "require 'date' is is upon you.

Current syck is mixed old YAML and YAML::Syck.
This breaks compatibility like following:
http://pc12.2ch.net/test/read.cgi/tech/1265467681/871

It also says require 'yaml/syck' should work.

People may require'yaml' and use YAML::Syck, but we should give up such case.

Bug #3112: require "yaml" doesn't use psych as default

Status: Open, Priority: Normal
Category: lib, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-04-08 trunk 27255)

why?

Rails runs with Psych as default. Our applications at work run well
with Psych as default.

I would like to make Psych default YAML parser for 1.9.2. What do you
think?

IMO, if Psych is enough compatible with Syck, Psych should be
the default YAML parser, like the way of the decision performed
about ext/fiddle and ext/dl recently.

However, naruse has already explained the intention of yugui at
[ruby-core:29377].
I don't want to disobey the branch/release manager about this
matter :)

Yugui,

I am worried about possible encoding issues that can come in Syck that will
be hard to fix. For instance, Aaron was able to fix Psych to honor
default_internal in just a few days, and there is no real maintainer for
Syck.

Since Aaron is the maintainer for Psych, and there is no maintainer for
Syck, I think it makes sense to make Psych the default, with the yamler=
option for backward compatibility.

I'm afraid that if we use Syck as default, no one will see errors from
invalid YAML files. If we make Psych as default, people will see errors
with their YAML files but have the option to move back to Syck.

Are we going to remove Syck in 1.9.3? If we don't make Psych default in
1.9.2, it seems to me that we have to wait until 1.9.4 to remove Syck.

Since Syck has no active maintainer, it seems bad to wait so long to
remove it.

Bump.

I think the lack of a Syck maintainer, yet making Syck the default in 1.9.2
needs to be addressed. 1.9.2 is probably going to be the de-facto release
for some time. What's the rationale for keeping an unmaintained major
component when a maintained version is available in the standard library?

I'm afraid that if we use Syck as default, no one will see errors from
invalid YAML files.  If we make Psych as default, people will see errors
with their YAML files but *have the option* to move back to Syck.

Are we going to remove Syck in 1.9.3?  If we don't make Psych default in
1.9.2, it seems to me that we have to wait until 1.9.4 to remove Syck.

Psych is an "opt-in" experience for 1.9.2. I'm not sure when we'll make
it the default YAML object.

There are two ways you can use Psych. The first way is to just require
psych and reference the Psych constant:

 require 'psych'
 
 Psych.load '--- hello world!'
 Psych.dump { :goodbye => 'cruel world' }

The second way is to change the YAML engine:

 require 'yaml'

 YAML::ENGINE.yamler = 'psych'
 YAML.load '--- hello world!'
 YAML.dump { :goodbye => 'cruel world' }

Setting the engine will replace the YAML constant with the Psych
constant. Using the first example will absolutely guarantee using
Psych. The second example cannot guarantee usage because other
libraries could possibly set the engine back to "syck" without your
knowledge.
