[Syllable-developer] libsylph - Whisper and archiver

[Rui C. <wai...@ya...>]

While i was looking for ways to add imap support to Whisper,the easy way, i came across this lib - http://sylpheed.sraoss.jp/en/download.html#libsylph .
It supports imap, pop3, smtp and its only dependencies are glib and openssl. My question does it dependency on glib mean Whisper be rewritten to use this lib as a backend? It would mean a big boost in terms of funcionality.
Can glib be included in the Syllable cd?
One other thing i've been looking at is archiver source, it has some bugs under 0.6.5 like not supporting blank spaces and some others with pipes (sometimes if i don't close the application it doesn't open files correctly). So i started looking to alternatives :) Like i said on the forum i've ported avfs which gives us support for most of the formats , through command line wrappers. Is avfs ok, or would be a C++ rewrite of the code , present on archiver, giving us a nice API to handle this kind of formats?
Something like:

using namespace archiver;

archive my_compressed_file = new archive("some file.zip");

namescpace archiver {

class archive{    
        public:    
            virtual void listFiles()=0;
            virtual void extractFiles(,string pathToExtract)=0;
            virtual void extractSelectedFile(string pathToExtract)=0;
            virtual void addNewFile(string file_to_add)=0;
            virtual void compress_dir(string dir)=0;
            string getCurrentFormat();
        private:
            void findArchiveFormat(string path);
            string current_format;        
            string filepath;
}

}
My idea would be to create an abstract datatype archive , which could be subclassed to add new types. I'm not a C++ expert so if u have comments,corrections, please let me know.

Its dependency on Glib discounts entirely from inclusion in Syllable.
I'm also a bit attached to libpop3 & libsmtp.

Looking at the example code for SMTP & POP3 the API & functionality is
very close to libpop3 & libsmtp anyway, so other than a few features
they currently do not support (SSL support, mostly) Whisper wouldn't
gain anything.

I'll also point out that IMAP support is perfectly possible with
Whisper: it just requires a suitable plugin to provide an IMAP mailbox.
It's just that no-one has written one yet. As a stop-gap, it would seem
feasible to write one on top of libsylph until we have an implementation
that doesn't depend on Glib, or find some way to negate the dependency.

I believe Rick has plans, but I don't know whether they include AVFS.
Rick?
