Corrected XPath operator precedence.
...
The previous commit didn't fully change the operator precedence according to
the XPath 1.0 specification. Also thanks to @whitequark for clearing up a few
things about Racc's operator precedence system.

Fixed XPath operator precedence.
...
Apparently using multiple `left` rules with T_AND and T_OR being separate
solves this problem. Riiiiight....

Parsing support for more XPath operators.
...
This still messes up some tests due to botched token precedence (by the looks
of it).

Lex XPath operators using individual tokens.

Instead of lexing every operator as T_OP they now use individual tokens such as
T_EQ and T_LT.

Upgrade to RSpec 3.0.
...
For this I've enabled both the old expectation and stubbing/mocking syntax. The
old syntax is much more compact and to me reads nicer. For example, consider
the following:
lex('<foo></foo>').should == [...]
To me this reads much nicer than this:
expect(lex('<foo></foo>')).to eq([...])

54de2df0c7
Support for lexing XPath wildcard expressions.
...
To support this we need to require whitespace around the "*" operator. This is
not ideal but it will do for now.

Basic working XPath lexer.

This doesn't lex everything of the XPath specification just yet and needs more

629dcd3fe6
Support for IO inputs in the lexer.
...
Using IO/StringIO objects one can parse large XML files without first having to
read the entire file into memory. This can potentially save a lot of memory at
the cost of a slightly slower runtime.
For IO like instances the lexer will consume the input line by line. If a
String is given it's consumed as a whole instead. A small side effect of
reading the input line by line is that text such as "foo\nbar" will be lexed as
two tokens instead of one.
Fixes #19 .

Use a method for getting input in the XML lexer.
...
Instead of directly accessing the `data` instance variable the C/Java code now
uses the method `read_data`. This is part of one of the various steps required
to allow Oga to read data from IO like instances. It also means I can freely
change the name of the instance variable without also having to change the
C/Java code.

Removed remaining fhold call in the XML lexer.

There's no particular need any more for this fhold call so we're getting rid of
it.

Replaced fcall/fret with fnext in the XML lexer.
...
With the rules being cleaned up/moved around a bit we can drop the use of
fcall/fret. This saves the need of having to maintain a stack (position).
2014-05-21 00:08:48 +02:00
c56b0395e4
Moved various rules around for the XML lexer.
...
This moves the element related rules to the element_head machine (where they
belong). This in turn makes it possible to lex ">" as a text node, previously
this was impossible.

The tokens T_COMMENT_START, T_TEXT and T_COMMENT_END have been merged into a
