# Project (context)

## Migrate project

Updates the project from an old version to the current one and saves the
resulting project in the output directory. Projects cannot be updated
inplace.

The command tries to map the old source configuration to the new one.
This can fail in some cases, so the command will exit with an error,
unless `-f/--force` is specified. With this flag, the command will
skip these errors an continue its work.

Usage:

``` bash
datum project migrate [-h] -o DST_DIR [-f] [-p PROJECT_DIR] [--overwrite]
```

Parameters:
- `-o, --output-dir` (string) - Output directory for the updated project
- `-f, --force` - Ignore source import errors (default: False)
- `--overwrite` - Overwrite existing files in the save directory.
- `-p, --project` (string) - Directory of the project to operate on
  (default: current directory).
- `-h, --help` - Print the help message and exit.

Examples:
- Migrate a project from v1 to v2, save the new project in other dir:
`datum project migrate -o <output/dir>`

## Print project info

Prints project configuration info such as available plugins, registered models,
imported sources and build tree.

Usage:

``` bash
datum project info [-h] [-p PROJECT_DIR] [revision]
```

Parameters:
- `<revision>` (string) - Target project revision. By default,
  uses the working tree.
- `-p, --project` (string) - Directory of the project to operate on
  (default: current directory).
- `-h, --help` - Print the help message and exit.

Examples:
- Print project info for the current working tree:
`datum project info`

- Print project info for the previous revision:
`datum project info HEAD~1`
