Fancier error messages for the parser.
...
The error messages of the parser now contain surrounding lines of code instead
of only the offending line of code. This should make debugging a bit easier.
Line numbers are also shown for each line.

Rip out column counting.
...
This makes both the lexer and parser quite a bit easier to use. Counting column
numbers isn't also really needed when parsing XML/HTML.
2014-03-20 19:44:28 +01:00
70a39042e7
Removed useless rules from the parser.
2014-03-20 18:58:32 +01:00
03774f2788
Documented the lexer.
2014-03-19 22:05:57 +01:00
192ba9bb54
Expanded the lexer comment tests.
2014-03-19 21:44:57 +01:00
f1fcdfbacb
Cleaned up the Ragel bits of the lexer.
...
This removes some of the complexity that existed before (e.g. too many state
machines) and fixes a bunch of problems with nested data.

Revert "Compacter parser AST."
...
Although this AST is compacter it will result in conflicts between (text),
(attributes) and (attribute) nodes in regular XML documents. This is due to XML
allowing elements with these names (unlike in HTML).
This reverts commit 8898d08831
2014-03-18 18:55:16 +01:00
9687dd379f
Added a .ruby-version file.
2014-03-18 18:08:25 +01:00
56f22c311e
Allow JRuby to fail for now.
2014-03-18 00:13:33 +01:00

Lowered the required Ragel version to 6.7.
2014-03-18 00:12:21 +01:00

Install Ragel on Travis CI.
2014-03-18 00:09:16 +01:00

Configuration file for Travis CI.
2014-03-17 21:52:24 +01:00

Removed the emit_text_buffer Ragel action.
2014-03-17 21:49:49 +01:00
274ab359ba
Don't use separate tokens/nodes for newlines.
...
Newlines are now lexed together with regular text. The line numbers are
advanced based on the amount of "\n" sequences in a text buffer.
2014-03-17 21:26:21 +01:00
8898d08831
Compacter parser AST.
...
The AST no longer uses the generic `element` type for element nodes but instead
changes the type based on the element type. That is, a <p> element now results
in an (p) node, <link> in (link), etc.
2014-03-17 21:03:54 +01:00
8d3f3f15d7
Renamed parse_html() to parse().
2014-03-16 23:46:20 +01:00
cb75edc30d
Basic support for lexing/parsing HTML5.
...
This will need a bunch of extra tests before I'll consider closing #7 .
2014-03-16 23:42:24 +01:00
ce8bbdb64a
Parsing support for multiple nested nodes.
2014-03-15 20:19:54 +01:00
05ee3c13c9
Parsing support for nested element/text nodes.
2014-03-14 00:44:11 +01:00
6b2f682c5c
Tests for lexing a basic HTML document.
...
This also comes with some changes to the lexer so that it advances column/line
numbers correctly.
2014-03-13 23:55:18 +01:00
edf2e4112b
Added a test for parsing bare text tokens.
2014-03-13 00:42:58 +01:00
34f8779c94
Lexing of bare regular text.
...
This is currently a bit of a hack but at least we're slowly getting there.
2014-03-13 00:42:12 +01:00
2fbca93ae8
Supported for parsing nested elements.
2014-03-12 23:13:28 +01:00
8cfa81aed9
Basic support for parsing elements.
...
This includes support for elements with namespaces and attributes. Nested
elements are not yet supported.
2014-03-12 23:02:54 +01:00
5ce515d224
Small line wrapping change in the lexer.
2014-03-12 22:42:13 +01:00
98b3443e7f
Lexing of element attributes without values.
2014-03-12 22:41:17 +01:00
ed9d8c05a2
Added support for parsing comments.
2014-03-12 22:20:12 +01:00
0a396043f8
Support for parsing CDATA tags.
2014-03-11 22:22:02 +01:00
c9592856f0
Updated parsing of doctypes.
...
The resulting nodes now separate the type, public and system IDs in to separate
string values.
2014-03-11 22:08:21 +01:00
c07edc767b
Updated the gitignore entry for the parser.
2014-03-11 22:03:02 +01:00
4a41894e2c
Updated the doctype parser specs.
2014-03-11 22:02:26 +01:00
8ce76be050
Moved the parser class to Oga::Parser.
...
Oga will use the same parser for XML and HTML so it doesn't make sense to
separate the two into different namespaces (at least for now).
2014-03-11 22:01:50 +01:00
77b40d2e81
Use a separate machine for closing tags.
...
This makes it easier to advance column numbers for whitespace as well as
captuing and emitting tokens for the closing tag.
2014-03-11 21:55:36 +01:00
eacd9b88cf
Reworked token generation for elements.
...
This emits separate tokens for the start tag (T_ELEMENT_OPEN) and name
(T_ELEMENT_NAME). This makes it easier to include the namespace of an element
(T_ELEMENT_NS) in the output.
2014-03-10 23:50:39 +01:00
cd53d5e426
Fixed advancing column numbers.
...
In a bunch of cases the column number would not be increased correctly.
2014-03-07 23:54:56 +01:00
1c9a6c8b76
Tests for nested tags/text nodes.
...
Well guess what, apparently that did work. That was slightly unexpected.
2014-03-03 22:13:29 +01:00
a5a3b8db3f
Basic lexing of HTML tags.
...
The current implementation is a bit messy. In particular the counting of column
numbers is not entirely the way it should be. There are also some problems with
nested tags/text that I still have to resolve.
2014-03-03 22:08:46 +01:00
d9ef33e1f8
Lexing of comments.
...
This fixes #4 .
2014-02-28 23:27:23 +01:00
92ae48f905
Use fcall + fret instead of fgoto.
...
This removes the hardcoded return to the main machine.
2014-02-28 23:19:31 +01:00
30d3e455d1
Use squote/dquote everywhere in the lexer.
2014-02-28 23:18:23 +01:00
970ce27283
Cleanup of buffering text/strings.
...
This removes the need to use ||= and such, which should speed things up a bit
and keeps the code cleaner.
2014-02-28 23:16:01 +01:00
ca6f422036
Lexing of doctypes.
...
This comes with various structural changes to the lexer as I'm slowly starting
to get the hang of Ragel. Ragel is a beast but damn it's an awesome piece of
software.
Note that the doctype public/system IDs are lexed as T_STRING. The parser will
figure out whether a ID is a public or system ID based on the order.
This fixes #1
2014-02-28 23:08:55 +01:00
3c825afee0
Cleaned up lexer rules a bit.
...
There's no benefit to adding variables for angle brackets and such, it's much
easier to grok to just use them directly.
2014-02-28 20:09:13 +01:00
2294bf19f4
Better lexing of CDATA tags.
...
This means the lexer is now capable of lexing CDATA tags that contain text such
as ]].
2014-02-28 20:05:12 +01:00
6138945d53
Moved some of the CDATA docs around.

Lexing of CDATA tags.
2014-02-28 00:03:37 +01:00
c011e2faaa
Moved the lexer specs to spec/oga/lexer.
...
I accidently moved these inside the parser specs.
2014-02-27 21:30:10 +01:00
cdaa14a28e
Broke up lexer specs into separate files.
2014-02-27 20:55:29 +01:00
2c82f88f6c
Basic lexing + parsing of doctypes.
...
We're doing these the lazy way. I can't be bothered writing patterns/rules for
4 different formats for something such as doctypes.
2014-02-27 01:27:51 +01:00
d7d20b4c23
Added a license.
