Dumping the backtrace for exceptions never worked, so lets remove it.

This is porting ruby/ruby#1992 to upstream.
This PR adds `uplelvel` to deprecation warning of Psych.
The `uplevel` option was introduced from Ruby 2.5.
ruby/psych needs to support Ruby 2.4 or lower.
This PR has `warn_with_uplevel` method emulating
`warn 'message', uplevel: 1` in Ruby 2.4 or lower.
And this PR relaxes the warning.

Fix fallback keyword argument of Psych.load
|
|
|
|
|
|
This allows calling Psych.load with a fallback argument,
similar to Psych.load_file. Before, for Psych.load this
caused a "NoMethodError: undefined method `to_ruby'".
|
|
|
|
This will be released in Psych 3.0.3. See #352.
|
|
|
|
This allows the AST to be searched via a predicate method rather than
hardcoding the class name and doing is_a? checks. For example, rather
than:
```
ast.grep(Psych::Nodes::Scalar).each do |node|
# .. do something
end
```
Now you can do:
```
ast.find_all(&:scalar?).each do |node|
# .. do something
end
```
Your code no longer needs to know the exact class used in the AST.
|
|
Add more test cases for the fallback keyword argument of
Psych.load_file; additionally, fix an error in the docs.

|
|
Convert fallback option to a keyword argument
|
|
Improve docs for Psych.safe_load
|
|
|
|
Converting the optional fallback argument to a keyword argument
fixes a problem that is caused by mixing optional arguments and
optional keyword arguments.
Without this change, a hash as fallback value is not handled
correctly: in Psych.load("", nil, {}) the hash is not interpreted
as the fallback value, and the default value for the fallback
argument is used instead.
|
|
Mention filename argument and symbolize_names keyword argument.

This adds a new reported event to Psych::Handler, event_location, with precise start/end line/column information.
The line/column information provided by Psych::Parser#mark is not very useful because it points to the location past the event.
