.. man NOTES

The FORMAT specifier syntax
+++++++++++++++++++++++++++

The ``--format`` option uses python's `format string syntax
<https://docs.python.org/3.9/library/string.html#formatstrings>`_.

Examples:
::

    $ borg diff --format '{content:30} {path}{NL}' ArchiveFoo ArchiveBar
    modified:  +4.1 kB  -1.0 kB    file-diff
    ...

    # {VAR:<NUMBER} - pad to NUMBER columns left-aligned.
    # {VAR:>NUMBER} - pad to NUMBER columns right-aligned.
    $ borg diff --format '{content:>30} {path}{NL}' ArchiveFoo ArchiveBar
       modified:  +4.1 kB  -1.0 kB file-diff
    ...

The following keys are always available:

- NEWLINE: OS dependent line separator
- NL: alias of NEWLINE
- NUL: NUL character for creating print0 / xargs -0 like output
- SPACE: space character
- TAB: tab character
- CR: carriage return character
- LF: line feed character


Keys available only when showing differences between archives:

- path: archived file path
- change: all available changes

- content: file content change
- mode: file mode change
- type: file type change
- owner: file owner (user/group) change
- group: file group change
- user: file user change

- link: file link change
- directory: file directory change
- blkdev: file block device change
- chrdev: file character device change
- fifo: file fifo change

- mtime: file modification time change
- ctime: file change time change
- isomtime: file modification time change (ISO 8601)
- isoctime: file creation time change (ISO 8601)
