Description

Manage sibling configuration

This command offers four different actions: ‘query’, ‘add’, ‘remove’, ‘configure’, ‘enable’. ‘query’ is the default action and can be used to obtain information about (all) known siblings. ‘add’ and ‘configure’ are highly similar actions, the only difference being that adding a sibling with a name that is already registered will fail, whereas re-configuring a (different) sibling under a known name will not be considered an error. ‘enable’ can be used to complete access configuration for non-Git sibling (aka git-annex special remotes). Lastly, the ‘remove’ action allows for the removal (or de-configuration) of a registered sibling.

For each sibling (added, configured, or queried) all known sibling properties are reported. This includes:

“name”
Name of the sibling
“path”
Absolute path of the dataset
“url”
For regular siblings at minimum a “fetch” URL, possibly also a “pushurl”

Additionally, any further configuration will also be reported using a key that matches that in the Git configuration.

By default, sibling information is rendered as one line per sibling following this scheme:

<dataset_path>: <sibling_name>(<+|->) [<access_specification]

where the + and - labels indicate the presence or absence of a remote data annex at a particular remote, and ACCESS_SPECIFICATION contains either a URL and/or a type label for the sibling.

Options

ACTION

command action selection (see general documentation). Constraints: value must be one of (‘query’, ‘add’, ‘remove’, ‘configure’, ‘enable’) [Default: ‘query’]

-h, –help, –help-np

show this help message. –help-np forcefully disables the use of a pager for displaying the help message

-d DATASET, –dataset DATASET

specify the dataset to configure. If no dataset is given, an attempt is made to identify the dataset based on the input and/or the current working directory. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path) [Default: None]

-s NAME, –name NAME

name of the sibling. For sibling removal this option is mandatory, otherwise the hostname part of a given URL is used as a default. This option can be used to limit ‘query’ to a specific sibling. Constraints: value must be a string [Default: None]

–url [URL]

the URL of or path to the dataset sibling named by NAME. For recursive operation it is required that a template string for building subdataset sibling URLs is given. List of currently available placeholders: %NAME the name of the dataset, where slashes are replaced by dashes. Constraints: value must be a string [Default: None]

–pushurl PUSHURL

in case the URL cannot be used to publish to the dataset sibling, this option specifies a URL to be used instead. If no URL is given, PUSHURL serves as URL as well. Constraints: value must be a string [Default: None]

-D DESCRIPTION, –description DESCRIPTION

short description to use for a dataset location. Its primary purpose is to help humans to identify a dataset copy (e.g., “mike’s dataset on lab server”). Note that when a dataset is published, this information becomes available on the remote side. Constraints: value must be a string [Default: None]

–fetch

fetch the sibling after configuration. [Default: False]

–as-common-datasrc NAME

configure the created sibling as a common data source of the dataset that can be automatically used by all consumers of the dataset (technical: git-annex auto- enabled special remote). [Default: None]

–publish-depends SIBLINGNAME

add a dependency such that the given existing sibling is always published prior to the new sibling. This equals setting a configuration item ‘remote.SIBLINGNAME .datalad-publish-depends’. This option can be given more than once to configure multiple dependencies. Constraints: value must be a string [Default: None]

–publish-by-default REFSPEC

add a refspec to be published to this sibling by default if nothing specified. Constraints: value must be a string [Default: None]

–annex-wanted EXPR

expression to specify ‘wanted’ content for the repository/sibling. See https ://git-annex.branchable.com/git-annex-wanted/ for more information. Constraints: value must be a string [Default: None]

–annex-required EXPR

expression to specify ‘required’ content for the repository/sibling. See https ://git-annex.branchable.com/git-annex-required/ for more information. Constraints: value must be a string [Default: None]

–annex-group EXPR

expression to specify a group for the repository. See https://git- annex.branchable.com/git-annex-group/ for more information. Constraints: value must be a string [Default: None]

–annex-groupwanted EXPR

expression for the groupwanted. Makes sense only if –annex-wanted=”groupwanted” and annex-group is given too. See https://git-annex.branchable.com/git-annex- groupwanted/ for more information. Constraints: value must be a string [Default: None]

–inherit

if sibling is missing, inherit settings (git config, git annex wanted/group/groupwanted) from its super-dataset. [Default: False]

–no-annex-info

Whether to query all information about the annex configurations of siblings. Can be disabled if speed is a concern. [Default: True]

-r, –recursive

if set, recurse into potential subdataset. [Default: False]

–recursion-limit LEVELS

limit recursion into subdataset to the given number of levels. Constraints: value must be convertible to type ‘int’ [Default: None]
