- README for ept
- ==============
-
- The intent of this library is to provide high-level access to all sorts of
- sources of information about Debian packages.
-
- There are four data providers currently implemented:
-
- - APT: access the APT database
- - Debtags: access the Debtags tag information
- - Popcon: access Popcon package scores
- - TextSearch: fast Xapian-based full text search on package description
-
- To enable the popcon data provider, just download the file
- http://popcon.debian.org/all-popcon-results.txt.gz and put it into
- /var/lib/popcon/ or ~/.popcon/ in the user's home directory.
-
- To enable the xapian fast search index, run ept-cache reindex as root.
-
- The xapian index is not regenerated automatically like with popcon and debtags
- because it takes a while to build. It is also not stored in the user's home
- directory because it is quite large.
-
-
- Development
- ===========
-
- The library revolves around two classes: Package and Version. These classes
- represent a package or one of its specific versions. Using these classes it is
- possible to query one or more data providers for information about the package.
-
- The idea is to have a way to represent a package or one of its versions, and
- that this way must be valid for any data provider.
-
- A data provider does not need to know about the others, nor it needs to
- implement a specific interface: the only requirement on a data provider is that
- it can be queried using Package and Version objects, as appropriate.
-
- It is easy to implement more data providers. It is also easy to implement new
- data providers outside of this library, as long as they can be queried using
- Package or Version objects.
-
- The 4 providers are currently shipped with the library to avoid having a chain
- of dependencies on the initial state of the project. It is straightforward,
- however, to package them separately from the core Package infrastructure.
-
-
- The development of libept is currently published in the Mercurial repository
- at: http://hg.debian.org/hg/private/enrico/libept
-
- It is possible to checkout a copy of the repository with the command:
-
- hg clone http://hg.debian.org/hg/private/enrico/libept
-
- Mercurial is a distributed version control system: you are encouraged to play
- with the code, join the development and publish your Mercurial tree.
