Hi Arunesh,
I'd need something like findByTitle(namespace, title) in zimlib: It returns an
iterator pointing
to the lexicographically next article. I'd like to use this to implement an
auto suggest
feature (Same as in online wikipedia search box).
Note: While for auto suggest iterating forward is necessary, for other features
it would be good if it is also
possible to iterate backward (same as in zimlib).
One other thing which may be currently missing is support for title and url
search/get article
functionality. It looks to me the right now everything operates on urls and not
on titles.
For searching it is necessary to also have title based functions. (Like
findByTitle).
Note that while currently in most zimfiles urls have the form
'Namespace'/'Title', this is not guaranteed,
the url could be completely different from the title.
Regarding performance, have you missed Brion's and my results posted in this
thread?
(They may be only in the [email protected] and not in the
[email protected] list)
Best regards,
Christian

Hi Christian,
You can look at getDirectoryInfo(String articleName, char
namespace) in ZimReader.java
This'll return null if there is the article doesn't exist, else the
DirectoryEntry object. (Is this what you were looking for?)
Actually I plan on adding more features if required. Do you think there are
any missing, when compared to zimlib? If yes, could you list them?
Have you tested zimreader-java on an Android phone? How is it's performance?

Hi Arunesh,
Firstly, thank you again for doing the java port.
I've one question regarding the features of the port:
Is there or do you plan to add a feature for iterating over the index?
(Similar to find/findByTitle in C++ zimlib)
This would be required to add some auto complete feature to the phonegap
app.
Best regards,
Christian

Yes, images are not compressed in ZIM files, as Emmanuel pointed out.
Also, I have tried decompressing a LZMA compressed file on an Android
phone (HTC Wildfire to be precise), and the decompression speed is not a
problem.
LZMA-Java is under frequent development by Lasse Collin, so we should
make sure that the latest code is used.

Images should not be compressed in ZIM files for the obvious reasons
they mainly are already compressed. This is the case for all ZIM files I
made. As far as I know this is also the case for Mediawiki:Collection
build ZIM files.
