When we do a search and paging the result, we need to display to the
user the total number of book, not only the `itemsPerPage`.
So, we need to parse correctly the xml to keep information of the total
number of book.
The value is store as a string in in the xml, so we cannot use getAsI.
We have to get the string and parse it to an int.
We cannot use strtoull because android stdc++ lib doesn't have it.
We have to implement our how parseFromString function using a
istringstream.
When parsing a opds feed, the favicon is a url, not a dataurl.
If we download the favicon all the times, it may take a lot of time to
parse the feed.
We store the url and download the favicon only when needed (when displayed)
- "winsock2.h" needs to be included before "windows.h". But if a
compilation unit include "windows.h" and after "networkTools.h", we
fails and it is complicated to handle. The include must not be in the
header but in the cpp
- windows define some ERROR macro. It is a pitty but we cannot use `ERROR`
in our enum.
- If build statically using mingw we need to define `CURL_STATICLIB`
Library client (kiwix-desktop) need to know when a book is added to
library by the manager. By using a LibraryManipulator, we can do
dependency injection.
It is up to the book to manage its attribute.
Also remove the `absolutePath` (and `indexAbsolutePath`). The `Book::path` is always stored
absolute.
The fact that the path can be stored absolute or relative in the
`library.xml` is not relevant for the book.
The previous API suffer different problems:
- It was difficult to handle articles redirecting to other article.
- It was not possible to get few information (title) without getting
the whole content.
The new API introduce the new class `Entry` that act as a proxy to an
article in the zim file.
Methods of `Reader` now return an `Entry` and the user has to call
`Entry`'s methods to get useful information.
No redirection is made explicitly.
If an entry is not found, an exception is raised instead of returning
an invalid `Entry`.
The common pattern to get the content of an entry become :
```
std::string content;
try {
auto entry = reader.getEntryFromPath(path);
entry = entry.getFinalEntry();
content = entry.getContent();
} catch (NoEntry& e) {
...
}
```
Older methods are keep (with the same behavior) but are marked as
deprecated.
The library's books are created in the metadata in the opds.
As the opds stream is by definition a distant "library", there is no
zim to read to complete missing information.
This can lead to incomplete `library.xml`.
The downloader is using libaria2.
For now, only one download can be run a the time.
A download will start only if (and as soon as) no download is running.
