Summary: Eden wants to be able to perform the purge itself, so Mercurial doesn't have to walk over the whole tree and so it can do it in bulk. Let's start by refactoring purge to be implemented within the filesystem layer, and moving the current implementation down.

|
|
|
|
Delete all untracked files in your checkout. Untracked files are files
|
|
that are unknown to Mercurial. They are marked with "?" when you run
|
|
:hg:`status`.
|
|
|
|
By default, :hg:`purge` does not affect::
|
|
|
|
- Modified and unmodified tracked files
|
|
- Ignored files (unless --all is specified)
|
|
- New files added to the repository with :hg:`add`, but not yet committed
|
|
- Empty directories that contain no files (unless --dirs is specified)
|
|
|
|
If directories are given on the command line, only files in these
|
|
directories are considered.
|
|
|
|
Caution: Be careful with purge, as you might irreversibly delete some files
|
|
you forgot to add to the repository. There is no way to undo an
|
|
:hg:`purge` operation. Run :hg:`status` first to verify the list of
|
|
files that will be deleted, or use the --print option with :hg:`purge`
|
|
to preview the results.
