NAME
datalad rerun - re-execute previous `datalad run` commands.
SYNOPSIS
datalad rerun [-h] [--since SINCE] [-d DATASET] [-b NAME] [-m MESSAGE] [--onto base] [--script FILE]
[--report] [--assume-ready {inputs|outputs|both}] [--explicit] [--version] [REVISION]
DESCRIPTION
This will unlock any dataset content that is on record to have been modified by the command in the speci‐
fied 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-or-pick: the revision does
not have a recorded command and would
be either skipped or cherry picked - merge: the revision is a merge commit and a corresponding merge
would
be made
The decision to skip rather than cherry pick a revision is based on whether the revision would be reach‐
able from HEAD at the time of execution.
In addition, when a starting point other than HEAD is specified, there is a rerun_action value "check‐
out", in which case the record includes information about the revision the would be checked out before
rerunning any commands.
NOTE 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.
Examples
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...
OPTIONS
REVISION
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. The default value is like "HEAD" but resolves
to the main branch when on an adjusted branch. Constraints: value must be a string
-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
-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)
-b NAME, --branch NAME
create and checkout this branch before rerunning the commands. Constraints: value must be a string
-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
--onto base
start point for rerunning the commands. If not specified, commands are executed at HEAD. This op‐
tion 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 the parent of the first run commit in the specified revision list. Constraints:
value must be a string
--script FILE
extract the commands into FILE rather than rerunning. Use - to write to stdout instead. This op‐
tion implies --report. Constraints: value must be a string
--report
Don't actually re-execute anything, just display what would be done. Note: If you give this op‐
tion, you most likely want to set --output-format to 'json' or 'json_pp'.
--assume-ready {inputs|outputs|both}
Assume that inputs do not need to be retrieved and/or outputs do not need to unlocked or removed
before running the command. This option allows you to avoid the expense of these preparation steps
if you know that they are unnecessary. Note that this option also affects any additional outputs
that are automatically inferred based on inspecting changed files in the run commit. Constraints:
value must be one of ('inputs', 'outputs', 'both')
--explicit
Consider the specification of inputs and outputs in the run record to be explicit. Don't warn if
the repository is dirty, and only save modifications to the outputs from the original record. Note
that when several run commits are specified, this applies to every one. Care should also be taken
when using --onto because checking out a new HEAD can easily fail when the working tree has modi‐
fications.
--version
show the module and its version which provides the command
