``gerbonara rewrite``
|

*********************
|

|
||||
.. program:: gerbonara rewrite
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
gerbonara rewrite [OPTIONS] INFILE OUTFILE
|
||||
|
||||
Parse a single gerber file, apply transformations, and re-serialize it into a new gerber file. Without transformations,
|
||||
this command can be used to convert a gerber file to use different settings (e.g. units, precision), but can also be
|
||||
used to "normalize" gerber files in a weird format into a more standards-compatible one as gerbonara's gerber parser is
|
||||
significantly more robust for weird inputs than others.
|
||||
|
||||
.. option:: --warnings <default|ignore|once>
|
||||
|
||||
Enable or disable file format warnings during parsing (default: on)
|
||||
|
||||
.. option:: -t, --transform <code>
|
||||
|
||||
Execute python transformation script on input. You have access to the functions ``translate(x, y)``,
|
||||
``scale(factor)`` and ``rotate(angle, center_x?, center_y?)``, the bounding box variables ``x_min``, ``y_min``,
|
||||
``x_max``, ``y_max``, ``width`` and ``height``, and everything from python's built-in math module (e.g. ``pi``,
|
||||
``sqrt``, ``sin``). As convenience methods, ``center()`` and ``origin()`` are provided to center the board
|
||||
respectively move its bottom-left corner to the origin. Coordinates are given in ``--command-line-units``, angles in
|
||||
degrees, and scale as a scale factor (as opposed to a percentage). Example: ``translate(-10, 0); rotate(45, 0, 5)``
|
||||
|
||||
.. option:: --command-line-units <metric|us-customary>
|
||||
|
||||
Units for values given in other options. Default: millimeter
|
||||
|
||||
.. option:: -n, --number-format <decimal.fractional>
|
||||
|
||||
Override number format to use during export in ``[integer digits].[decimal digits]`` notation, e.g. ``2.6``.
|
||||
|
||||
.. option:: -u, --units <metric|us-customary>
|
||||
|
||||
Override export file units
|
||||
|
||||
.. option:: -z, --zero-suppression <off|leading|trailing>
|
||||
|
||||
Override export zero suppression setting. Note: The meaning of this value is like in the Gerber spec for both Gerber
|
||||
and Excellon files!
|
||||
|
||||
.. option:: --keep-comments, --drop-comments
|
||||
|
||||
Keep gerber comments. Note: Comments will be prepended to the start of file, and will not occur in their old
|
||||
position.
|
||||
|
||||
.. option:: --default-settings, --reuse-input-settings
|
||||
|
||||
Use sensible defaults for the output file format settings (default) or use the same export settings as the input file
|
||||
instead of sensible defaults.
|
||||
|
||||
.. option:: --input-number-format <decimal.fractional>
|
||||
|
||||
Override number format of input file (mostly useful for Excellon files)
|
||||
|
||||
.. option:: --input-units <metric|us-customary>
|
||||
|
||||
Override units of input file
|

.. code-block:: console
|
||||
|
||||
gerbonara transform [OPTIONS] TRANSFORM INPATH OUTPATH
|
||||
|
||||
Transform all gerber files in a given directory or zip file using the given python transformation script.
|
||||
|
||||
In the python transformation script you have access to the functions ``translate(x, y)``, ``scale(factor)`` and
|
||||
``rotate(angle, center_x?, center_y?)``, the bounding box variables ``x_min``, ``y_min``, ``x_max``, ``y_max``,
|
||||
``width`` and ``height``, and everything from python's built-in math module (e.g. ``pi``, ``sqrt``, ``sin``). As
|
||||
convenience methods, ``center()`` and ``origin()`` are provided to center the board resp. move its bottom-left corner to
|
||||
the origin. Coordinates are given in --command-line-units, angles in degrees, and scale as a scale factor (as opposed to
|
||||
a percentage). Example: ``translate(-10, 0); rotate(45, 0, 5)``
|
||||
|
||||
.. option:: -m, --input-map <json_file>
|
||||
|
||||
Extend or override layer name mapping with name map from JSON file. The JSON file must contain a single JSON dict
|
||||
with an arbitrary number of string: string entries. The keys are interpreted as regexes applied to the filenames via
|
||||
re.fullmatch, and each value must either be the string ``ignore`` to remove this layer from previous automatic
|
||||
guesses, or a gerbonara layer name such as ``top copper``, ``inner_2 copper`` or ``bottom silk``.
|
||||
|
||||
.. option:: --use-builtin-name-rules, --no-builtin-name-rules
|
||||
|
||||
Disable built-in layer name rules and use only rules given by ``--input-map``
|

|

.. option:: --warnings <default|ignore|once>
|
||||
|
||||
Enable or disable file format warnings during parsing (default: on)
|

.. option:: --units <metric|us-customary>
|

Units for values given in other options. Default: millimeter
|

|
||||
.. option:: -n, --number-format <decimal.fractional>
|
||||
|

Override number format to use during export in ``[integer digits].[decimal digits]`` notation, e.g. ``2.6``.
|
||||
|
||||
.. option:: --default-settings, --reuse-input-settings
|
||||
|
||||
Use sensible defaults for the output file format settings (default) or use the same export settings as the input file
|
||||
instead of sensible defaults.
|
||||
|
||||
.. option:: --force-zip
|
||||
|
||||
Force treating input path as a zip file (default: guess file type from extension and contents)
|
||||
|
||||
.. option:: --output-naming-scheme <altium|kicad>
|
||||
|
||||
Name output files according to the selected naming scheme instead of keeping the old file names.

``gerbonara merge``
|
||||
*******************
|
||||
|

.. program:: gerbonara merge
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ gerbonara merge [OPTIONS] [INPATH]... OUTPATH
|
||||
|
||||
Merge multiple single Gerber or Excellon files, or multiple stacks of Gerber files, into one.
|
||||
|
||||
.. note::
|
||||
When used with only one input, this command *normalizes* the input, converting all files to a well-defined, widely
|
||||
supported Gerber subset with sane settings. When a ``--output-naming-scheme`` is given, it additionally renames all
|
||||
files to a standardized naming convention.
|
||||
|
||||
.. option:: --command-line-units <metric|us-customary>
|
||||
|
||||
Units for values given in --transform. Default: millimeter
|
||||
|
||||
.. option:: --warnings <default|ignore|once>
|
||||
|
||||
Enable or disable file format warnings during parsing (default: on)
|
||||
|
||||
.. option:: --offset <COORDINATE>
|
||||
|
||||
Offset for the n'th file as a ``x,y`` string in unit given by ``--command-line-units`` (default: millimeter). Can be
|
||||
given multiple times, and the first option affects the first input, the second option affects the second input, and
|
||||
so on.
|
||||
|
||||
.. option:: --rotation <ROTATION>
|
||||
|
||||
Rotation for the n'th file in degrees clockwise, optionally followed by comma- separated rotation center X and Y
|
||||
coordinates. Can be given multiple times, and the first option affects the first input, the second option affects the
|
||||
second input, and so on.
|
||||
|
||||
.. option:: -m, --input-map <json_file>
|
||||
|
||||
Extend or override layer name mapping with name map from JSON file. This option can be given multiple times, in which
|
||||
case the n'th option affects only the n'th input, like with ``--offset`` and ``--rotation``. The JSON file must
|
||||
contain a single JSON dict with an arbitrary number of string: string entries. The keys are interpreted as regexes
|
||||
applied to the filenames via re.fullmatch, and each value must either be the string "ignore" to remove this layer
|
||||
from previous automatic guesses, or a gerbonara layer name such as ``top copper``, ``inner_2 copper`` or ``bottom
|
||||
silk``.
|
||||
|
||||
.. option:: --default-settings, --reuse-input-settings
|
||||
|
||||
Use sensible defaults for the output file format settings (default) or use the same export settings as the input file
|
||||
instead of sensible defaults.

||||
Name output files according to the selected naming scheme instead of keeping the old file names of the first input.
|
||||
|
||||
.. option:: --output-board-name <TEXT>
|
||||
|
||||
Override board name used with ``--output-naming-scheme``
|
||||
|
||||
.. option:: --use-builtin-name-rules, --no-builtin-name-rules
|
||||
|
||||
Disable built-in layer name rules and use only rules given by --input-map

|
||||
Print the bounding box of a gerber file in ``[x_min] [y_min] [x_max] [y_max]`` format. The bounding box contains all
|
||||
graphic objects in this file, so e.g. a 100 mm by 100 mm square drawn with a 1mm width circular aperture will result in

an 101 mm by 101 mm bounding box.
