Gerbonara can open a folder of manufacturing files, and parse file names and metadata to figure out which +file contains what. Gerbonara is tested using an extensive library of real-world example files from CAD tools including +KiCAD, Altium, Eagle, Allegro, gEDA, Fritzing, Siemens/Mentor Graphics PADS, and Target3001!.</p> +<p>Gerbonara's API is built on two principles:</p> +<dl class="docutils"> +<dt><strong>Meaningful, object-oriented API</strong></dt> +<dd>Gerbonara abstracts away the details of the underlying file format such as tool indices, coordinate notation and +graphical state, and presents meaningful "graphical objects" such as a <cite>primitives.Line</cite>, +<cite>primitives.Arc</cite>, or <cite>Region</cite> through its API. These objects can be easily created, +manipulated or deleted from code without breaking anything else. You can even copy graphical objects between files, +and Gerbonara will automatically convert coordinate format, units etc. for you. <cite>GerberFile</cite> and +<cite>ExcellonFile</cite> use the same types of <cite>graphic objects <object-api></cite>, so objects can be directly +copied between file types without conversion.</dd> +<dt><strong>Unit-safety</strong></dt> +<dd>Gerbonara embeds physical <cite>LengthUnit</cite> information in all objects. The high-level API such as +<cite>LayerStack.merge</cite> or <cite>GerberFile.offset</cite> accepts arguments with an explicitly given unit and +automatically converts them as needed. Objects can be copied between <cite>GerberFile</cite> instances and unit +conversion will be handled transparently in the background.</dd> +</dl> +<p>Gerbonara was started as an extensive refactoring of the <a class="reference external" href="https://github.com/opiopan/pcb-tools-extension">pcb-tools</a> and <a class="reference external" href="https://github.com/curtacircuitos/pcb-tools/issues">pcb-tools-extension</a> packages. Both of these +have statement-based APIs, that is, they parse input files into one python object for every line in the file. This means +that when saving files they can recreate the input file almost byte by byte, but manipulating a file by changing +statements without breaking things is <em>hard</em>.</p> +<p>Gerbonara powers <a class="reference external" href="https://github.com/jaseg/gerbolyze">gerbolyze</a>, a tool for converting <a class="reference external" href="https://en.wikipedia.org/wiki/Scalable_Vector_Graphics">SVG</a> vector graphics files into Gerber, and embedding <a class="reference external" href="https://en.wikipedia.org/wiki/Scalable_Vector_Graphics">SVG</a> into +existing Gerber files exported from a normal PCB tool for artistic purposes.</p> +<div class="section" id="features"> +<h2>Features</h2> +<blockquote> +<ul class="simple"> +<li>File I/O +* Gerber, Excellon (drill file), IPC-356 (netlist) read and write +* supports file-level operations: offset, rotate, merge for all file types</li> +<li>Modification API (<cite>GraphicObject</cite>)</li> +<li>Rendering API (<cite>GraphicPrimitive</cite>)</li> +<li>SVG export</li> +<li>Full aperture macro support, including transformations (offset, rotation)</li> +</ul> +</blockquote> +</div> +<div class="section" id="quick-start"> +<h2>Quick Start</h2> +<p>First, install gerbonara from PyPI using pip:</p> +<pre class="code shell literal-block"> +pip<span class="whitespace"> </span>install<span class="whitespace"> </span>--user<span class="whitespace"> </span>gerbonara +</pre> +<p>Then, you are ready to read and write gerber files:</p> +<pre class="code python literal-block"> +<span class="keyword namespace">from</span> <span class="name namespace">gerbonara</span> <span class="keyword namespace">import</span> <span class="name">LayerStack</span><span class="whitespace"> + +</span><span class="name">stack</span> <span class="operator">=</span> <span class="name">LayerStack</span><span class="operator">.</span><span class="name">from_directory</span><span class="punctuation">(</span><span class="literal string single">'output/gerber'</span><span class="punctuation">)</span><span class="whitespace"> +</span><span class="name">w</span><span class="punctuation">,</span> <span class="name">h</span> <span class="operator">=</span> <span class="name">stack</span><span class="operator">.</span><span class="name">outline</span><span class="operator">.</span><span class="name">size</span><span class="punctuation">(</span><span class="literal string single">'mm'</span><span class="punctuation">)</span><span class="whitespace"> +</span><span class="name builtin">print</span><span class="punctuation">(</span><span class="literal string affix">f</span><span class="literal string single">'Board size is </span><span class="literal string interpol">{</span><span class="name">w</span><span class="literal string interpol">:</span><span class="literal string single">.1f</span><span class="literal string interpol">}</span><span class="literal string single"> mm x </span><span class="literal string interpol">{</span><span class="name">h</span><span class="literal string interpol">:</span><span class="literal string single">.1f</span><span class="literal string interpol">}</span><span class="literal string single"> mm'</span><span class="punctuation">)</span> +</pre> +</div> +<div class="section" id="command-line-interface"> +<h2>Command-Line Interface</h2> +<p>Gerbonara comes with a <cite>built-in command-line interface<cli-doc></cite> that has functions for analyzing, rendering, +modifying, and merging Gerber files.
