R"""Add files from the working tree, specific blobs, or
:class:`~git.index.typ.BaseIndexEntry`\s to the index.
:param items:
Multiple types of items are supported, types can be mixed within one call.
Different types imply a different handling. File paths may generally be
relative or absolute.
- path string
Strings denote a relative or absolute path into the repository pointing
to an existing file, e.g., ``CHANGES``, ``lib/myfile.ext``,
``/home/gitrepo/lib/myfile.ext``.
Absolute paths must start with working tree directory of this index's
repository to be considered valid. For example, if it was initialized
with a non-normalized path, like ``/root/repo/../repo``, absolute paths
to be added must start with ``/root/repo/../repo``.
Paths provided like this must exist. When added, they will be written
into the object database.
PathStrings may contain globs, such as ``lib/__init__*``. Or they can be
directories like ``lib``, which will add all the files within the
directory and subdirectories.
This equals a straight :manpage:`git-add(1)`.
They are added at stage 0.
- :class:`~git.objects.blob.Blob` or
:class:`~git.objects.submodule.base.Submodule` object
Blobs are added as they are assuming a valid mode is set.
The file they refer to may or may not exist in the file system, but must
be a path relative to our repository.
If their sha is null (40*0), their path must exist in the file system
relative to the git repository as an object will be created from the
data at the path.
The handling now very much equals the way string paths are processed,
except that the mode you have set will be kept. This allows you to
create symlinks by settings the mode respectively and writing the target
of the symlink directly into the file. This equals a default Linux
symlink which is not dereferenced automatically, except that it can be
created on filesystems not supporting it as well.
Please note that globs or directories are not allowed in
:class:`~git.objects.blob.Blob` objects.
They are added at stage 0.
- :class:`~git.index.typ.BaseIndexEntry` or type
Handling equals the one of :class:`~git.objects.blob.Blob` objects, but
the stage may be explicitly set. Please note that Index Entries require
binary sha's.
:param force:
**CURRENTLY INEFFECTIVE**
If ``True``, otherwise ignored or excluded files will be added anyway. As
opposed to the :manpage:`git-add(1)` command, we enable this flag by default
as the API user usually wants the item to be added even though they might be
excluded.
:param fprogress:
Function with signature ``f(path, done=False, item=item)`` called for each
path to be added, one time once it is about to be added where ``done=False``
and once after it was added where ``done=True``.
``item`` is set to the actual item we handle, either a path or a
:class:`~git.index.typ.BaseIndexEntry`.
Please note that the processed path is not guaranteed to be present in the
index already as the index is currently being processed.
:param path_rewriter:
Function, with signature ``(string) func(BaseIndexEntry)``, returning a path
for each passed entry which is the path to be actually recorded for the
object created from :attr:`entry.path <git.index.typ.BaseIndexEntry.path>`.
This allows you to write an index which is not identical to the layout of
the actual files on your hard-disk. If not ``None`` and `items` contain
plain paths, these paths will be converted to Entries beforehand and passed
to the path_rewriter. Please note that ``entry.path`` is relative to the git
repository.
:param write:
If ``True``, the index will be written once it was altered. Otherwise the
changes only exist in memory and are not available to git commands.
:param write_extension_data:
If ``True``, extension data will be written back to the index. This can lead
to issues in case it is containing the 'TREE' extension, which will cause
the :manpage:`git-commit(1)` command to write an old tree, instead of a new
one representing the now changed index.
This doesn't matter if you use :meth:`IndexFile.commit`, which ignores the
'TREE' extension altogether. You should set it to ``True`` if you intend to
use :meth:`IndexFile.commit` exclusively while maintaining support for
third-party extensions. Besides that, you can usually safely ignore the
built-in extensions when using GitPython on repositories that are not
handled manually at all.
All current built-in extensions are listed here:
