NAME¶datalad rerun - re-execute previous `datalad run` commands.
datalad rerun [-h] [--since SINCE] [-d DATASET] [-b NAME] [-m MESSAGE] [--onto base] [--script FILE] [--report] [REVISION]
DESCRIPTION¶This will unlock any dataset content that is on record to have been modified by the command in the specified revision. It will then re-execute the command in the recorded path (if it was inside the dataset). Afterwards, all modifications will be saved.
Report mode¶When called with --report, this command reports information about what would be re-executed as a series of records. There will be a record for each revision in the specified revision range. Each of these will have one of the following "rerun_action" values:
- run: the revision has a recorded command that would be re-executed - skip: the revision does not have a recorded command and would be skipped - pick: the revision does not have a recorded command and would be cherry picked
The decision to skip rather than cherry pick a revision is based on whether the revision would be reachable from HEAD at the time of execution.
In addition, when a starting point other than HEAD is specified, there is a rerun_action value "checkout", in which case the record includes information about the revision the would be checked out before rerunning any commands.
Re-execute the command from the previous commit::
% datalad rerun
Re-execute any commands in the last five commits::
% datalad rerun --since=HEAD~5
Do the same as above, but re-execute the commands on top of HEAD~5 in a detached state::
% datalad rerun --onto= --since=HEAD~5
Re-execute all previous commands and compare the old and new results::
% # on master branch % datalad rerun --branch=verify --since= % # now on verify branch % datalad diff --revision=master.. % git log --oneline --left-right --cherry-pick master...
- Currently the "onto" feature only sets the working tree of the current dataset to a previous state. The working trees of any subdatasets remain unchanged.
- rerun command(s) in REVISION. By default, the command from this commit will be executed, but --since can be used to construct a revision range. Constraints: value must be a string [Default: 'HEAD']
- -h, --help, --help-np
- show this help message. --help-np forcefully disables the use of a pager for displaying the help message
- --since SINCE
- If SINCE is a commit-ish, the commands from all commits that are reachable from REVISION but not SINCE will be re-executed (in other words, the commands in git log SINCE..REVISION). If SINCE is an empty string, it is set to the parent of the first commit that contains a recorded command (i.e., all commands in git log REVISION will be re-executed). Constraints: value must be a string [Default: None]
- -d DATASET, --dataset DATASET
- specify the dataset from which to rerun a recorded command. If no dataset is given, an attempt is made to identify the dataset based on the current working directory. If a dataset is given, the command will be executed in the root directory of this dataset. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path) [Default: None]
- -b NAME, --branch NAME
- create and checkout this branch before rerunning the commands. Constraints: value must be a string [Default: None]
- -m MESSAGE, --message MESSAGE
- use MESSAGE for the reran commit rather than the recorded commit message. In the case of a multi-commit rerun, all the reran commits will have this message. Constraints: value must be a string [Default: None]
- --onto base
- start point for rerunning the commands. If not specified, commands are executed at HEAD. This option can be used to specify an alternative start point, which will be checked out with the branch name specified by --branch or in a detached state otherwise. As a special case, an empty value for this option means to use the commit specified by --since. Constraints: value must be a string [Default: None]
- --script FILE
- extract the commands into FILE rather than rerunning. Use - to write to stdout instead. This option implies --report. Constraints: value must be a string [Default: None]
- Don't actually re-execute anything, just display what would be done. Note: If you give this option, you most likely want to set --output-format to 'json' or 'json_pp'. [Default: False]
