Checkout#

This command allows to restore a specific project revision in the project tree or to restore separate revisions of sources. A revision can be a commit hash, branch, tag, or any relative reference in the Git format.

This command has multiple forms:

1) datum checkout <revision>
2) datum checkout [--] <source1> ...
3) datum checkout <revision> [--] <source1> <source2> ...

1 - Restores a revision and all the corresponding sources in the working directory. If there are conflicts between modified files in the working directory and the target revision, an error is raised, unless --force is used.

2, 3 - Restores only selected sources from the specified revision. The current revision is used, when not set.

“–” can be used to separate source names and revisions:

  • datum project checkout name - will look for revision “name”

  • datum project checkout -- name - will look for source “name” in the current revision

Usage:

datum project checkout [-h] [-f] [-p PROJECT_DIR] [rev] [--] [sources [sources ...]]

Parameters:

  • --force - Allows to overwrite unsaved changes in case of conflicts

  • -p, --project (string) - Directory of the project to operate on (default: current directory).

  • -h, --help - Print the help message and exit.

Examples:

  • Restore the previous revision: datum project checkout HEAD~1

  • Restore the saved version of a source in the working tree datum project checkout -- source-1

  • Restore a previous version of a source datum project checkout 33fbfbe my-source
