Hello David,
thank you for the reply.
I need the begin and end offset of each component, so for each token
type (heading, link, image) I know its exact position in the raw document.
If we know their position, we can mark each component according to the
type in the rawtext more easily (similar to WikiText editor).
(e. g.: for marking bold, marking as link etc.)
But where could I find
org.eclipse.mylyn.internal.wikitext.ui.editor.syntax.FastMarkupPartitioner.PartitionBuilder.
Regards,
Luven

Luven,
The good news: The WikiText parser is used behind the scenes in the
WikiText editor -- so yes, it can give you the offsets that you need
to know where things are in the source markup. The bad news: this
functionality was retrofitted into the WikiText parser and is probably
not the most intuitive API.
You're pointed in the right direction.
org.eclipse.mylyn.wikitext.core.parser.Locator is indeed the place to
get the offsets that you need. The WikiText markup editor uses a
DocumentBuilder to build a model of the document with exact offsets.
A good place to start looking
is org.eclipse.mylyn.internal.wikitext.ui.editor.syntax.FastMarkupPartitioner.PartitionBuilder.
If you feel that there are bugs in the implementation (including
documentation bugs or lacking documentation) please post a bug at
bugs.eclipse.org <http://bugs.eclipse.org> under Tools/Mylyn/WikiText.
If you're able to attach JUnit tests that exercise/demonstrate the
bug, that's even better.
To satisfy my curiosity, perhaps you could tell me more about your use
case: Why do you want to know these offsets?
Regards,
David

Hello,
now I like to get the begin and end offset of each links in
wikitext. Later maybe other components (images).
Is that possible to do this using Mylyn WikiText?
I tried to use getLocator().getDocumentOffset() in method:
void
org.eclipse.mylyn.wikitext.core.parser.builder.NoOpDocumentBuilder.link(Attributes
attributes, String hrefOrHashName, String text) and
void
org.eclipse.mylyn.wikitext.core.parser.builder.NoOpDocumentBuilder.characters(String
text)
but I found out that document offset is not updated after calling
method link(Attributes attributes, String hrefOrHashName, String
text).
The offset is also sometimes decremented. So far I now, it should
be only incremented.
I test by using this simple text below as my MediaWiki WikiText:
The '''EditorX''' is an [[text editor|editor]] of small to
medium-sized [[text]].
This is a [[test]] too ('''yes''').
_*The Result*_*:*
*Offset
* *Component type
* *Value
* *Comment*
-1 DOCUMENT_BEGIN
[]
0 BLOCK_BEGIN
[PARAGRAPH]
0 CHARACTERS_GROUP [*The *]
4 SPAN_BEGIN [BOLD]
7 CHARACTERS_GROUP [*EditorX*]
7 SPAN_END [BOLD]
17 CHARACTERS_GROUP [* is an *]
*7*
LINK [*editor*] The offset is anyhow decremented (¿*Bug*?)
7
CHARACTERS_GROUP [* of small to medium-sized *] Now is all
offset incorrect
55 LINK
[*text*]
55 CHARACTERS_GROUP [*.*]
*83* CHARACTERS_GROUP [] New line position is correct
now.
83 CHARACTERS_GROUP [*This is a *]
93 LINK [*test*]
*93* CHARACTERS_GROUP [* too (*] 93 is offset of the link
*107* SPAN_BEGIN [BOLD] Here is correct again
110 CHARACTERS_GROUP
[*yes*]
110 SPAN_END [BOLD]
116 CHARACTERS_GROUP [*).*]
118 BLOCK_END [PARAGRAPH]
118 DOCUMENT_END []
For heading I am currently using:
getLocator().getLineDocumentOffset() for beginOffset and
getLocator().getLineDocumentOffset()+getLocator().getLineLength()
for endOffset
and it works so far.
It does not work for link because there can be some links in the
same line.
Best regards,
Luven

Thank you David,
that is the functionality I need. I've tried also with headings
and images.
And it works too.
Best regards,

You want to do something like this:
public class ExtractHyperlinksBuilder extends NoOpDocumentBuilder {
private Set<String> hyperlinks = new HashSet<String>();
@Override
public void link(Attributes attributes, String hrefOrHashName,
String text) {
hyperlinks.add(hrefOrHashName);
}
@Override
public void imageLink(Attributes linkAttributes, Attributes
imageAttributes, String href, String imageUrl) {
hyperlinks.add(href);
}
public Set<String> getHyperlinks() {
return hyperlinks;
}
}
MarkupParser parser =
new
MarkupParser(ServiceLocator.getInstance().getMarkupLanguage("MediaWiki"));
ExtractHyperlinksBuilder builder = new ExtractHyperlinksBuilder();
parser.setBuilder(builder);
Reader markupContent = null;// open reader
try {
parser.parse(markupContent);
} finally {
markupContent.close();
}
// do something with builder.getHyperlinks()

Hello everyone,
I am a new Mylyn user. I'm planning to work with Wiki
Articles with java and eclipse.
Is that possible to extract attributes like hyperlinks,
headings, images, etc. directly from e. g. wikimedia
markup-language using WikiText.
like:
- obj.getHyperlinks();
If it is possible or maybe there is solutions for this, how
could it be done?
Thank you and best regards
Luven
