Lexer specs for the various XPath axes.
2014-06-13 00:16:40 +02:00
eba2d9954d
Support for parsing basic XPath expressions.
2014-06-12 00:20:46 +02:00
70f3b7fa92
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.

7244e28eec
Corrected docs of the xpath lexer.

114bc0d6e8
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([...])

1d2f9e6db6
Added T_STAR as an XPath parser token.
2014-06-02 09:27:25 +02:00
e11b9ed32c
Basic XPath parser setup.
2014-06-01 23:02:28 +02:00
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.
2014-06-01 23:01:24 +02:00
48bf1a0628
Tweak Gemspec file list a bit.
...
This ensures it also takes files such as "Rakefile" into account when needed.
2014-06-01 22:16:55 +02:00
b7855c124f
XPath lexer test for predicates using axes.
2014-06-01 19:49:37 +02:00
88b06e247d
Added a few more XPath lexer tests.
2014-06-01 19:43:36 +02:00
8dd8d7a519
Basic working XPath lexer.
...
This doesn't lex everything of the XPath specification just yet and needs more
tests.
2014-06-01 19:24:35 +02:00
a50b76a2d8
Cleaned up XPath lexer boilerplate a bit.
2014-05-29 19:25:49 +02:00
e0b07332d9
Boilerplate for the XPath lexer.
2014-05-29 19:25:49 +02:00
be3f8fb494
Removed the on_newline XML lexer callback.
2014-05-29 14:21:48 +02:00
ead5c71fee
Cleaned up the XML parser grammar.
...
This resolves all shift/reduce and reduce/reduce conflicts that were previously
present.
2014-05-29 01:37:19 +02:00
49780e2b04
Fix for useless XML parser rules.
...
Something tells me that using : and | in your syntax might not be the best
decision.

Rewind IO input upon resetting the lexer.
2014-05-26 00:33:20 +02:00
c81c6db74e
Benchmarks/profilers for IO inputs in the lexer.
2014-05-26 00:31:15 +02:00
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.

418b4ef498
Cleaned up documentation of the XML lexer.
2014-05-21 00:21:21 +02:00
3a8582030d
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.
2014-05-21 00:11:39 +02:00
4542f06d0f
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.
2014-05-21 00:04:53 +02:00
feaf28d423
Remove dedicated string machine in the XML lexer.
...
This removes the need for another fcall/fret combination.
2014-05-19 20:26:07 +02:00
93b9718406
Cleaned up the XML lexer documentation.
2014-05-19 09:39:35 +02:00
cd0f3380c4
Merge multiple CDATA tokens into a single token.
...
The tokens T_CDATA_START, T_TEXT and T_CDATA_END have been merged together into
T_CDATA.
2014-05-19 09:36:19 +02:00
a4fb5c1299
Merge multiple comment tokens into a single one.
...
The tokens T_COMMENT_START, T_TEXT and T_COMMENT_END have been merged into a
single token: T_COMMENT. This simplifies both the lexer and the parser.
2014-05-19 09:30:30 +02:00
c891dd88cb
Removed useless code from the XML parser.
2014-05-18 23:30:26 +02:00

Fixed guard in the lexer header.

Don't create Arrays when not needed.
2014-05-16 17:05:42 +02:00

Added average benchmarks for the parser.

Only include debug info when DEBUG is set.
2014-05-15 20:43:48 +02:00

Only set explicit ivars in the lexer.
2014-05-15 19:48:18 +02:00
44bf1dd1ca
Split up handling of element names/namespaces.
...
This is now split up on Ragel level, simplifying the corresponding Ruby code.
2014-05-15 10:22:05 +02:00
723a273e4f
Enforce symbols for element attributes.
...
This comes with a little bit of memory overhead but this should be minor in
most cases.
2014-05-15 01:04:26 +02:00
f4b9bbd4ac
Removed lazy way of setting instance variables.
...
This process is quite a bit slower compared to setting instance variables
directly.
2014-05-15 00:43:13 +02:00
043ea9a366
Fall back to ps in the profiler.
...
If the /proc filesystem doesn't exist we'll fall back to using the `ps` shell
command.
2014-05-11 21:15:33 +02:00
1b58723e7d
Removed stdioh. #include.
...
This header is also not needed.
2014-05-11 21:06:55 +02:00
e2b9fc75ca
Removed #include for malloc.h
...
Apparently some OS' move this to malloc/malloc.h. Since it's not needed lets
just get rid of it.
2014-05-11 21:06:02 +02:00
ba3d96c819
Re-build lexers when base_lexer.rl changes.
...
Thanks to @avdi for bringing up on how to do this when using rule() blocks.
2014-05-10 00:28:23 +02:00
19f04f98f7
Support for lexing/parsing inline doctypes.
2014-05-10 00:28:11 +02:00
a92023fe94
Removed outdated paragraph from the README.
...
Ironically Oga now uses native extensions for the lexer.

Manually bootstrap JRuby after all.
...
After discussing this with @headius I've decided to do this the manual way
anyway. Apparently the basic load service stuff is deprecated and not very
reliable.
