## Summary
WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output (SVG, PNG, ...) thanks to [GraphViz](https://www.graphviz.org/). It handles automatic BOM (Bill of Materials) creation and has a lot of extra features.
## Features
* WireViz input files are fully text based
* No special editor required
* Human readable
* Easy version control
* YAML syntax
* UTF-8 input and output files for special character support
* Understands and uses color abbreviations as per [IEC 60757](https://en.wikipedia.org/wiki/Electronic_color_code#Color_band_system) (black=BK, red=RD, ...)
<!-- * Optionally outputs colors as abbreviation (e.g. 'YE'), full name (e.g. 'yellow') or hex value (e.g. '#ffff00'), with choice of UPPER or lower case (#158) -->
* Auto-generates standard wire color schemes and allows custom ones if needed
* [DIN 47100](https://en.wikipedia.org/wiki/DIN_47100) (WT/BN/GN/YE/GY/PK/BU/RD/BK/VT/...)
* [IEC 60757](https://en.wikipedia.org/wiki/Electronic_color_code#Color_band_system) (BN/RD/OR/YE/GN/BU/VT/GY/WT/BK/...)
* [25 Pair Color Code](https://en.wikipedia.org/wiki/25-pair_color_code#Color_coding) (BUWH/WHBU/OGWH/WHOG/GNWH/WHGN/BNWH/...)
* [TIA/EIA 568 A/B](https://en.wikipedia.org/wiki/TIA/EIA-568#Wiring) (Subset of 25-Pair, used in CAT-5/6/...)
* Understands wire gauge in mm² or AWG
* Optionally auto-calculates equivalent gauge between mm² and AWG
* Is suitable for both very simple cables, and more complex harnesses.
* Allows for easy-autorouting for 1-to-1 wiring
* Generates BOM (Bill of Materials)
_Note_: WireViz is not designed to represent the complete wiring of a system. Its main aim is to document the construction of individual wires and harnesses.
## Examples
### Demo 01
[WireViz input file](../examples/demo01.yml):
```yaml
connectors:
X1:
type: D-Sub
subtype: female
pinlabels: [DCD, RX, TX, DTR, GND, DSR, RTS, CTS, RI]
X2:
type: Molex KK 254
subtype: female
pinlabels: [GND, RX, TX]
cables:
W1:
gauge: 0.25 mm2
length: 0.2
color_code: DIN
wirecount: 3
shield: true
connections:
-
- X1: [5,2,3]
- W1: [1,2,3]
- X2: [1,3,2]
-
- X1: 5
- W1: s
```
Output file:
[Bill of Materials](../examples/demo01.bom.tsv) (auto-generated)
### Demo 02
[Source](../examples/demo02.yml) - [Bill of Materials](../examples/demo02.bom.tsv)
### Syntax, tutorial and example gallery
Read the [syntax description](syntax.md) to learn about WireViz' features and how to use them.
See the [tutorial page](../tutorial/readme.md) for sample code, as well as the [example gallery](../examples/readme.md) to see more of what WireViz can do.
## Usage
### Installation
#### Requirements
WireViz requires Python 3.7 or later.
WireWiz requires GraphViz to be installed in order to work. See the [GraphViz download page](https://graphviz.org/download/) for OS-specific instructions.
_Note_: Ubuntu 18.04 LTS users in particular may need to separately install Python 3.7 or above, as that comes with Python 3.6 as the included system Python install.
#### Installing the latest release
The latest WireViz release can be downloaded from [PyPI](https://pypi.org/project/wireviz/) with the following command:
```
pip3 install wireviz
```
#### Installing the development version
Access to the current state of the development branch can be gained by cloning the repo and installing manually:
```
git clone <repo url>
cd <working copy>
git checkout dev
pip3 install -e .
```
If you would like to contribute to this project, make sure you read the [contribution guidelines](CONTRIBUTING.md)!
### How to run
```
$ wireviz ~/path/to/file/mywire.yml
```
Depending on the options specified, this will output some or all of the following files:
```
mywire.gv GraphViz output
mywire.svg Wiring diagram as vector image
mywire.png Wiring diagram as raster image
mywire.bom.tsv BOM (bill of materials) as tab-separated text file
mywire.html HTML page with wiring diagram and BOM embedded
```
Wildcards in the file path are also supported to process multiple files at once, e.g.:
```
$ wireviz ~/path/to/files/*.yml
```
To see how to specify the output formats, as well as additional options, run:
```
$ wireviz --help
```
### (Re-)Building the example projects
Please see the [documentation](buildscript.md) of the `build_examples.py` script for info on building the demos, examples and tutorial.
## Changelog
See [CHANGELOG.md](CHANGELOG.md)
## Status
This is very much a work in progress. Source code, API, syntax and functionality may change wildly at any time.
