Yorick Peterse bc49af02a2 XPath compiler support for the parent axis 2015-08-19 20:14:22 +02:00
Yorick Peterse ca7930cbf4 XPath compiler support for "descendant" 2015-08-19 20:14:22 +02:00
Yorick Peterse f8671a96b7 Fixed compiler support for descendant-or-self 2015-08-19 20:14:22 +02:00
Yorick Peterse 23379d6467 Fixed node() type test for the XPath compiler
This ensures the handler behaves the same as in the old XPath evaluator.

Yorick Peterse 4da1c637bc Cleaned up descendant-or-self compiler specs 2015-08-19 20:14:22 +02:00
Yorick Peterse 8a49d9c0ee Basic compiler support for descendant-or-self
The generated code isn't entirely correct which considering the tests do
pass means the tests need to be fixed too.

Yorick Peterse d50f89cdf1 Use "node" for axis variables
This ensures that any nested code uses the right variables.
2015-08-19 20:14:22 +02:00
Yorick Peterse 045cfe4ab8 XPath compiler support for operators in predicates
Previously the operator methods would ignore any blocks set by the
on_predicate family of methods.
2015-08-19 20:14:22 +02:00
Yorick Peterse aa8386e6f3 Cleaned up compiler handling of axes/calls
Function call handlers don't receive a single AST node, instead they
receive the XPath arguments as separate method arguments.

Yorick Peterse bfc970a95a XPath compiler support for type tests 2015-08-19 20:14:21 +02:00
Yorick Peterse ef59f160c7 XPath compiler support for true()/false() 2015-08-19 20:14:21 +02:00
Yorick Peterse 2eb12eced6 XPath compiler support for all operators
Some specs still fail due to true()/false() not being implemented but
the operators themselves should work just fine.

Yorick Peterse 3a18d23792 to_boolean support for truthy Ruby values 2015-08-19 20:14:21 +02:00
Yorick Peterse 06ae1503d4 nodes/attributes support in to_compatible_types
This extends XPath::Conversion.to_compatible_types so that it can also
take XML::Node and XML::Attribute objects as input.
2015-08-19 20:14:21 +02:00
Yorick Peterse 376d016acd Expanded supported input for Conversion.to_float
This extends XPath::Conversion.to_float so it can also convert NodeSet
and Node instances.

Yorick Peterse 0e9f533358 Use return_nodeset? vs USE_NODESET 2015-08-19 20:14:21 +02:00
Yorick Peterse 9000d5efdb XPath::Compiler#compile specifies blocks for paths
Previously the on_path method itself would specify a block to use when a
node was matched. This makes it impossible to customize this behaviour
which is needed when a path is used in an operator or predicate. By
letting the #compile() method specify the block other handlers can
overwrite it.

Yorick Peterse e549b28ca4 Removed useless YARD docs from the XPath compiler
The method names already explain their intent.

Yorick Peterse 4f03bf19c1 XPath compiler support for "ancestor" 2015-08-19 20:14:21 +02:00
Yorick Peterse f96b30fb1f Tag the XPath compiler as private 2015-08-19 20:14:21 +02:00
Yorick Peterse f7484f1c8d Use each_ancestor for ancestor-or-self in XPath
The XPath compiler now uses XML::Node#each_ancestor for compiling the
"ancestor-or-self" axis.
2015-08-19 20:14:20 +02:00
Yorick Peterse 52741a3b78 Added XML::Node#each_ancestor
This method can be used to walk through the ancestor tree of a Node.
2015-08-19 20:14:20 +02:00
Yorick Peterse db39b25546 XPath compiler support for ancestor-or-self
This also comes with some changes to the specs as the old behaviour of
the Evaluator was incorrect. The Evaluator would bail after matching a
single node but instead it's meant to continue until it runs out of
parent nodes.

Yorick Peterse 9925b2a9c9 XPath compiler support for predicates
This currently supports index predicates (e.g. "foo[10]") and predicates
using paths (e.g. foo[bar/baz]). The usage of boolean operators and more
complex expressions has not yet been tested as these are not yet
supported in the first place.

Yorick Peterse d11a754946 Basic support for compiling XPath to Ruby
This currently comes with exactly 0% test coverage. Once I've
implemented all required handler methods I'll be updating the current
evaluator tests to use the compiler instead. This removes the need for
writing an entirely new set of tests.

Currently the compiler is only capable of compiling basic expressions
such as "foo", "foo/bar" and "foo[@x="y"]/bar".

Yorick Peterse 337d126264 Added Ruby::Generator class
This class will be used to serialize a Ruby AST back to valid Ruby
source code (as a String).
2015-08-19 20:14:20 +02:00
Yorick Peterse 6673f176d8 Added Oga::Ruby::Node
This class will be used for building Ruby ASTs that will be generated
based on XPath expressions.
