datalad diff [-h] [-f REVISION] [-t REVISION] [-d DATASET] [--annex [{basic|availability|all}]] [--untracked {no|normal|all}] [-r] [-R LEVELS] [--version] [PATH ...]

The two to-be-compared states are given via the --from and --to options. These state identifiers are evaluated in the context of the (specified or detected) dataset. In the case of a recursive report on a dataset hierarchy, corresponding state pairs for any subdataset are determined from the subdataset record in the respective superdataset. Only changes recorded in a subdataset between these two states are reported, and so on.

Any paths given as additional arguments will be used to constrain the difference report. As with Git's diff, it will not result in an error when a path is specified that does not exist on the filesystem.

Reports are very similar to those of the STATUS command, with the distinguished content types and states being identical.

PATH

path to constrain the report to. Constraints: value must be a string or value must be NONE

-h,  --help,  --help-np

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

-f REVISION, --from REVISION

original state to compare to, as given by any identifier that Git understands. Constraints: value must be a string [Default: 'HEAD']

-t REVISION, --to REVISION

state to compare against the original state, as given by any identifier that Git understands. If none is specified, the state of the working tree will be compared. Constraints: value must be a string or value must be NONE

-d DATASET, --dataset DATASET

specify the dataset to query. If no dataset is given, an attempt is made to identify the dataset based on the current working directory. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path) or value must be NONE

--annex [{basic|availability|all}]

Switch whether to include information on the annex content of individual files in the status report, such as recorded file size. By default no annex information is reported (faster). Three report modes are available: basic information like file size and key name ('basic'); additionally test whether file content is present in the local annex ('availability'; requires one or two additional file system stat calls, but does not call git-annex), this will add the result properties 'has_content' (boolean flag) and 'objloc' (absolute path to an existing annex object file); or 'all' which will report all available information (presently identical to 'availability'). The 'basic' mode will be assumed when this option is given, but no mode is specified. Constraints: value must be one of ('basic', 'availability', 'all')

--untracked {no|normal|all}

If and how untracked content is reported when comparing a revision to the state of the working tree. 'no': no untracked content is reported; 'normal': untracked files and entire untracked directories are reported as such; 'all': report individual files even in fully untracked directories. Constraints: value must be one of ('no', 'normal', 'all') [Default: 'normal']

-r,  --recursive

if set, recurse into potential subdatasets.

-R LEVELS, --recursion-limit LEVELS

limit recursion into subdatasets to the given number of levels. Constraints: value must be convertible to type 'int' or value must be NONE

--version

show the module and its version which provides the command
