Method: Rugged::Repository#checkout_tree

Defined in:

ext/rugged/rugged_repo.c

#checkout_tree(treeish[, options]) ⇒ Object

Updates files in the index and working tree to match the content of the tree pointed at by the treeish.

The following options can be passed in the options Hash:

:progress

A callback that will be executed for checkout progress notifications. Up to 3 parameters are passed on each execution:

• The path to the last updated file (or nil on the very first invocation).

• The number of completed checkout steps.

• The number of total checkout steps to be performed.

:notify

A callback that will be executed for each checkout notification types specified with :notify_flags. Up to 5 parameters are passed on each execution:

• An array containing the :notify_flags that caused the callback execution.

• The path of the current file.

• A hash describing the baseline blob (or nil if it does not exist).

• A hash describing the target blob (or nil if it does not exist).

• A hash describing the workdir blob (or nil if it does not exist).

:strategy

A single symbol or an array of symbols representing the strategies to use when performing the checkout. Possible values are:

:none

Perform a dry run (default).

:safe

Allow safe updates that cannot overwrite uncommitted data.

:recreate_missing

Allow checkout to recreate missing files.

:force

Allow all updates to force working directory to look like index.

:allow_conflicts

Allow checkout to make safe updates even if conflicts are found.

:remove_untracked

Remove untracked files not in index (that are not ignored).

:remove_ignored

Remove ignored files not in index.

:update_only

Only update existing files, don’t create new ones.

:dont_update_index

Normally checkout updates index entries as it goes; this stops that.

:no_refresh

Don’t refresh index/config/etc before doing checkout.

:disable_pathspec_match

Treat pathspec as simple list of exact match file paths.

:skip_locked_directories

Ignore directories in use, they will be left empty.

:skip_unmerged

Allow checkout to skip unmerged files (NOT IMPLEMENTED).

:use_ours

For unmerged files, checkout stage 2 from index (NOT IMPLEMENTED).

:use_theirs

For unmerged files, checkout stage 3 from index (NOT IMPLEMENTED).

:update_submodules

Recursively checkout submodules with same options (NOT IMPLEMENTED).

:update_submodules_if_changed

Recursively checkout submodules if HEAD moved in super repo (NOT IMPLEMENTED).

:disable_filters

If true, filters like CRLF line conversion will be disabled.

:dir_mode

Mode for newly created directories. Default: 0755.

:file_mode

Mode for newly created files. Default: 0755 or 0644.

:file_open_flags

Mode for opening files. Default: IO::CREAT | IO::TRUNC | IO::WRONLY.

:notify_flags

A single symbol or an array of symbols representing the cases in which the :notify callback should be invoked. Possible values are:

:none

Do not invoke the :notify callback (default).

:conflict

Invoke the callback for conflicting paths.

:dirty

Invoke the callback for “dirty” files, i.e. those that do not need an update but no longer match the baseline.

:updated

Invoke the callback for any file that was changed.

:untracked

Invoke the callback for untracked files.

:ignored

Invoke the callback for ignored files.

:all

Invoke the callback for all these cases.

:paths

A glob string or an array of glob strings specifying which paths should be taken into account for the checkout operation. nil will match all files. Default: nil.

:baseline

A Rugged::Tree that represents the current, expected contents of the workdir. Default: HEAD.

:target_directory

A path to an alternative workdir directory in which the checkout should be performed.
