"""
Formatters are classes receiving packaging instructions
and creating the
appropriate package layout.
There are three distinct formatters, each handling one of the different chrome
formats:
- flat: essentially, copies files
from the source
with the same file system
layout. Manifests entries are grouped
in a single manifest per directory,
as well
as XPT interfaces.
- jar: chrome content
is packaged
in jar files.
- omni: chrome content, modules, non-binary components,
and many other
elements are packaged
in an omnijar file
for each base directory.
The base interface provides the following methods:
- add_base(path [, addon])
Register a base directory
for an application
or GRE,
or an addon.
Base directories usually contain a root manifest (manifests
not
included
in any other manifest) named chrome.manifest.
The optional addon argument tells whether the base directory
is that of a packed addon (
True), unpacked addon (
'unpacked')
or
otherwise (
False).
The method may only be called
in sorted order of `path` (alphanumeric
order, parents before children).
- add(path, content)
Add the given content (BaseFile instance) at the given virtual path
- add_interfaces(path, content)
Add the given content (BaseFile instance)
as an interface. Equivalent
to add(path, content)
with the right add_manifest().
- add_manifest(entry)
Add a ManifestEntry.
- contains(path)
Returns whether the given virtual path
is known of the formatter.
The virtual paths mentioned above are paths
as they would be
with a flat
chrome.
Formatters all take a FileCopier instance they will fill
with the packaged
data.
